Vibration isolation of hotels

Staying at a hotel can be the relaxing escape we all need every now and then or the necessary place to rest while on business. Either way, it is expected that you will have the amount of silence required to achieve a peaceful night’s sleep.

Hotel reviews in online media are increasingly used. 96% consider reviews important when researching a hotel. 79% will read between six and 12 reviews before making a purchase decision. Four out of five believe a hotel that responds to reviews cares more about its customers. 85% agree that a thoughtful response to a review will improve their impression of the hotel.

The demand for acoustic insulation and vibrations is increasingly high. A recent analysis of online guest reviews done by ReviewPro reveals that noise is the number one most common complaint by consumers in all but one city. The reviews came from 5,683 hotels in 20 key tourist destinations. Except from Cape Town in South Africa, noise is among the five worst rated concepts in the remaining 19 cities—garnering more negative mentions than other complaints. Hotel “elevators” were the second-largest source of complaints, followed by negative mentions about “smells”, ReviewPro’s analysis shows. Negative references to air conditioning and heating systems are also worth noting, since they were highlighted in twice as many reviews as Internet issues.

In newly built hotels or in renovation projects, AMC Mecanocaucho provides products that can solve this disturbance. In a hotel there are plenty of sources of noise, for example, rooftop machinery installations, rooftop pools, kitchens, bathroom extraction fans, lifts, laundries, or the increasingly popular rooftop bars on the terraces and rooftops. Soundproofing these areas, will provide us good acoustic insulation results.

“It’s so loud and the bass is so strong that it’s impossible to sleep” according to one Trip Advisor review.

These rooms or equipment generate structural noise/vibration and if they do not have a proper acoustic insulation, they transmit noise to the adjacent rooms. On many occasions, the most exclusive rooms are those located on the top floor, just below the main sources of noise and vibration. Addressing the vibration problems and providing a correct acoustic insulation can save important reimbursement claims as they are often the most expensive hotel rooms.

In addition, we can also find gyms and leisure rooms such as bars or pubs on any floor of the hotel, without a correct acoustic insulation, they can be a source of disturbance. It is also interesting to consider soundproofing the transit zones, as they are also one of the most relevant areas where noise is generated.

“It is also interesting to consider soundproofing the transit zones, as they are also one of the most relevant areas where noise is generated.”

AMC-Mecanocaucho, has a technical department and a range of products that can meet the highest demands in terms of acoustic insulation. It has a wide range of soundproofing solutions for the different noise and vibration sources discussed above. The integration of elastic suspensions can reduce the transmitted noise by more than 20 dB, transforming an annoying room into one with complete acoustic insulation.

BOX IN BOX CONCEPT AND MACHINE ISOLATION.

Box-in-box is a construction technique that allows a space within a space to be insulated against unwanted extraneous noise and vibration. Such extraneous noise may be airborne (travelling through the air) or they may be structure-borne – travelling through the ground and hotel structure. Noise is an audible vibration, therefore machinery or equipment that vibrate can generate noise disturbance, therefore should have also an acoustic insulation.

“Noise is an audible vibration”

Discover how “Silent Hotel” achieves a correct structural acoustic insulation .

This is principle of this soundproofing technique consists on decoupling the floor, walls and ceiling products to correct the airborne and structure borne noise transmission. This is often achieved with elastic anti vibration mounts supporting the suspended ceiling; called acoustic hangers, walls anti vibration mounts, called acoustic wall ties or floors, called floating floor anti vibration mounts. Noise absorption and mineral wool based acoustic insulation materials are often used on the air gaps, they provide thermal and reduce the reverberation inside the air gaps.

There are plenty of sources of structural noise in Hotels, and many possible mounts/systems according to the budget and level of soundproofing required.

Since the structure of the hotel plays a key role, the soundproofing solutions may not be “plug and play”. Hotels have their own natural frequencies and vibration shapes. AMC MECANOCAUCHO strongly advices to contact a professional acoustic consultant. On the following link a worldwide list of acoustic consultant associations. You can also contact if you want to get in touch with specialized acoustic consultant that will have experience treating cases like yours. AMC-MECANOCAUCHO visits acoustic consultants and develops its products jointly with the advice of many of them across the world.

In order to reduce the structural transmission of noise, elastic elements are used. The elasticity of the anti vibration mount plays a major role on the transmission of structural noise.

There are several elastic materials that can be used, such as springs, rubber, Sylomer® or even combination between them. The parameter that is used to define how elastic is a material is called stiffness (k). This parameter defines the force over displacement (N/mm or Lb/in).

Hotels are complex structures and simplifications do not always work, but it can be said that the higher the stiffness of the anti vibration mounts, (acoustic hangers, wall ties or floor anti vibration mounts) the higher the natural frequency. The higher the natural frequency, the most likely is to interfere with the disturbing frequency created by machines or human activity. This leads us to lower vibration/acoustic insulation, therefore hard materials are not the best materials when soundproofing premises.

10.jpg

“The higher the stiffness of the anti vibration mount, the higher its natural frequency. Stiff materials, are not the best materials when soundproofing premises.”

Doing a simplification, it can be said that the softer the anti vibration mounts are, the higher the acoustic insulation / lower structure borne noise.

Special care must be taken to coil springs. Even if they may have low stiffness, high frequencies can go through the spring and create resonances that can be audible if the spring is not surrounded with elastomeric materials.

11.jpg

“The lower the natural frequency is, the wider is the spectra of frequencies that will be isolated.”

1.- Removing structural noise in Swimming pools.

Contractors and Architects are increasingly obliged to offer a touch of exclusivity and a wow factor in their constructions due to the wide range of housing available today. One resource vastly gaining ground is the rooftop swimming pool. But this dream can turn into a nightmare for others; swimming pools are an important source of structural noise and vibrations that are transmitted to the adjacent rooms, creating bothersome noise for their residents.

14.jpg

AMC Mecanocaucho offers a simple acoustic insulation solution that largely attenuates structure-borne noise and vibrations. The solution lies in installing an anti vibration mount under to the swimming pool basin such as Sylomer® or Sylodyn® materials. This treatment is very simple to apply and has no effect on the traditional way pools are installed. The system involves fitting an elastic sheet to the framework, covering the entire surface onto which the swimming pool basin will subsequently be installed. It is essential to fit the elastic suspension to both the floor and the walls of the pool basin to ensure complete elastic separation and prevent acoustic bridges from occurring.

15.jpg

The good acoustic insulation results obtained are visible in projects carried out, where they successfully meet the strictest of international acoustic regulations. In this applications engineers AMC-MECANOCAUCHO seek to provide <10Hz of natural frequency systems. Onsite acoustic tests show the following results.

Before: 45 dB(A) + 9 dB(A) of penalisation for impulsive and low frequency: 54 dB(A)

After: 34 dB(A) + 3 dB(A) of penalisation for impulsive and low frequency: 37 dB(A)

2.- Removing structural noise from HVAC , machinery and piping on rooftops.

Eccentric vibrating machinery provide installation challenges on hotels. The vibration levels disturb adjacent hotels/neighbors causing noise complains.

In order to reduce the level of vibration on the machinery it is advisable to install the machine with anti vibration mounts that provide a sufficiently low natural frequency, so a high degree of isolation is achieved. HVAC equipment in rooftops are often placed on relatively thin slabs. These mass and stiffness of these slabs, favorize the transmission of structural noise. Therefore, in order to achieve a successful soundproofing, anti vibration mounts that have low stiffness, will help transmit less vibration to slab. The lower the vibration level on the slab, the lower vibration and audible noise will be transmitted to the below room. Spring anti vibration mounts that incorporate a soundproofing material like Sylomer® underneath and have lateral buffers against wind are effective for achieving good results. More info on this link: Vibrabsorber+Sylomer® antiseismic.

“Spring anti vibration mounts that incorporate a soundproofing material like Sylomer® underneath and have lateral buffers against wind are effective for achieving good results. More info on this link: Vibrabsorber+Sylomer® antiseismic.”

AMC-MECANOCAUCHO has developed a mobile app called Vibration Isolator pro that allows engineers to make their own calculations. This app provides calculates the vibration isolation efficiency requiring simple information as:

  1. Total load.

  2. Disturbing frequency.

  3. % of vibration isolation required.

“The app that allows you to select the vibration isolator that you need”

30.jpg 31.jpg

Not all the machinery requires high specification Spring anti vibration mounts or vibration isolators, small machinery, such as condensers, splits, small compressors can be isolated on a cost effective way using a soundproofing material called Sylomer®. This soundproofing material comes in different colours according to the load capacity. There are products that use this elastic material in form of machine feet, they are called TSR+Sylomer®.

They provide a natural frequency of around 10Hz. So they are convenient for those machines where the peak measured on the Vibration Isolator pro app, give as a peak of 30Hz or higher.

23.jpg

24.jpg

Generator sets in Rooftops, are generally more complex as their eccentricity is higher than an HVAC equipment. They will require very soft anti vibration mounts, so structural transmission to the below room is also low. During the start and stop of the gensets, we cross the resonance of the system, this may lead to great movements of the genset.

Installing this machinery in concrete slabs, lowers the vibration amplitude, this can generate a very positive effect as the vibration intensity will also decrease.

The FZ Spring+Sylomer® Jack up anti vibration mounts help to reduce the vibration amplitude of the generator set at the source, their low stiffness assures low vibration transmission and helps to avoid great movements of the genset specially when they are switched off.

25.jpg

“Watch the installation process of the FZ Spring+Sylomer Jack up anti vibration mounts”

Pipes, ducts, downspouts and other channels may transmit noise to the adjacent rooms. It is advisable that pipes get decoupled. EP+Sylomer type B can be a correct solution for this type of installation.

27.jpg

28.jpg

In order to select the correct pipe anti vibration mount, we need to know the load per point and the disturbing frequency. The disturbing frequency is measured in Hz. Acoustic consultants are equipped with vibration measurement equipment, they would be able to give you correct advice.

In case that an acoustic consultant can not be contacted, a possible way of knowing the frequency is using the Vibration isolator pro app or the compatible VIP accelerometer that is available for a price of 300€.

37.jpg

Watch VIP accelerometer in action

38.jpg

If the value of the measurement shows a predominant peak of X we recommend to select a pipe mount that has a natural frequency X/3 or lower. This should provide us an structural acoustic isolation above 80%.

Example: Load per point: 15 Kg. Value measured 33 Hz on the pipe. Then Natural frequency of the EP+ Sylomer® should be 33/3= 11Hz or lower. On the below case we can see the the EP+ Sylomer® provides a natural frequency of 9Hz.

31.jpg

32.jpg

Vibration isolator pro app shows 33Hz.

Catalogue information on EP+ Sylomer® Showing 9Hz.

3.- Removing structural noise in lower ground machinery, parking doors and ducts.

Machinery in the basement can be very different nature, from pumps, compressors Gensets, parking doors, ducts to transformers. Being installed on a lower ground, we may not need to go so low in natural frequency as if this machinery was installed on a rooftop. The stiff structures (ground) provide resonate less than rooftop slabs.

Anti vibration mounts are often installed beneath vibrating machines, in many cases where there is a fixing hole of a frame. Although this may be a practical and fast way of fixing the anti vibration mounts, special caution must be made so the frames do not “hang” causing cyclical bending moments that can lead to noise or ruptures caused by fatigue.

33.jpg

34.jpg

An easy way to solve this situation is by placing the anti vibration mounts at each corner of the frame. This way we will assure that frames are not swinging at its own natural frequency. If the distance between anti vibration mounts is greater than 1,5m we often recommend installing anti vibration mounts between. This measure helps the stability and avoids frames from twisting or bending avoiding supplementary structural noise that can cause disturbance.

AMC-MECANOCAUCHO has developed an online tool that allows engineers to make their own calculation. This calculation software calculates the vibration isolation efficiency requiring simple information as:

1. Total load.

2. Centre of gravity position.

3. Position of anti vibration mounts.

4. Disturbing frequency.

SOUNDPROOFING GARAGE DOORS AND PARKING ENTRANCE.

It can be annoying to have a garage door that rattles, squeaks, and shrieks as it opens and closes. Some hotel guests claim they can hear and feel their garage door opening in every room. Garage doors create vibrations during opening and closing. This results in loud and distracting noises. It might not be a problem during the day, but if you are trying to sleep, it can be disruptive. Reduce the vibrations, and you will reduce the noise level. The first steps should be to do a maintenance first on the rollers, replace them if they are worn out change and lubricate them. This will help the soundproofing.

36.jpg

37.jpg

“Reduce the vibrations, and you will reduce the noise level”

Your garage door may also be noisy because the acoustic insulation strip on the bottom of the door is worn out or missing. With a missing insulation strip, you will feel cold and wet coming into your garage and hear a loud banging noise when the door is closed. You can easily replace this acoustic insulation strip by removing the old one and purchasing a roll soundproofing material such as Sylomer®. Slide-out the old and worn strip and slide the new Sylomer® through the tracks in the door.

If after the noise is still there, we may need use anti vibration mounts under the engine or decouple the frame of the door with anti vibration mounts.

38.jpg 39.jpg

“If maintenance operations do not reduce the noise, decoupling of engine and frame may address the problem.”

SOUNDPROOFING LOWER GROUND DUCTS

Ducts, especially when they are metallic, they are likely to cause vibrations and noise. This vibration can travel through rigid fixation studs to upper floors causing a disturbing noise. It is advisable that ducts get decoupled. Acoustic hangers depending on their stiffness these anti vibration mounts can provide a higher or lower acoustic insulation.

In order to select the correct pipe anti vibration mount, we need to know the load per point and the disturbing frequency. The disturbing frequency is measured in Hz. Acoustic consultants are equipped with vibration measurement equipment, they would be able to give you correct advice.

40.jpg

Ducts isolated on acoustic hangers can provide a correct structural and acoustic insulation depending on their natural frequency.

In case that an acoustic consultant can not be contacted, a possible way of knowing the frequency is using the Vibration isolator pro app or the compatible VIP accelerometer that is available for a price of 300€.

Watch VIP accelerometer in action

If the value of the measurement shows a predominant peak of X we recommend to select a pipe mount that has a natural frequency X/3 or lower . This should provide us an isolation above 80%.

4.- Soundproofing floors.

Suspending elastically the floors is one of the most effective measures to reduce the noise transmission on Hotels between floors, specially if the source of the noise is on the floor itself (People walking on a upper floor Café-Restaurant, or dancing with high heels on rooftop bar).

The noise generated on a floor can travel through rigid structures and can be audible on multiple floors across the hotel. The geometry of the building and its vibration shapes may favorize higher vibration levels in floors that may be very distant from the source of noise. Since this may be a major source of complains to hotel owners, it is recommended to decouple the floor.

43.jpg

“Café Charbon” Floating floor isolation.

There are many ways where floors can be soundproofed. One of the most popular is to make a floating floor based on point bearings such as floor blocks, these systems can prevent the transmission with improvements of up to 31 dBs in impact noise. The construction principle is a very simple system and admits both concrete and dry floors based on boards.

45.jpg

46.jpg

The range of the different densities of the Floor blocks, which give us different load capacities, allows us to use them with an unrivaled durability in the different applications.

Nevertheless there are a wide variety of floating floor anti vibration mounts. The parameters for the selection will depend on the requirement for acoustic insulation, available space, requirement of levelling in case that the hotel must be renovated, requirement to insert cables beneath the floor (technical floor) and of course cost of the system. In order to have a clear view of all the possibilities below there is an overview of the different floating floor anti vibration mounts available.

5.- Acoustic insulation of ceilings and walls.

Following the box in box concept, the walls and ceilings must also be decoupled if we want to have a correct soundproofing of the room.

Using or not a suspended ceiling with acoustic hangers can provide provide important gains in airborne and impact noise. If we follow the below structure, the difference in impact noise is 31 dB and 20dB for airborne noise.

“Using or not using a suspended ceiling with acoustic hangers can represent a difference of 31dB in impact noise and 20dB in airborne noise”.

The concept is very similar to the floating floor anti vibration mounts, there is a wide variety of systems The parameters for the selection will depend on the requirement for acoustic insulation, available space and of course cost of the system.

More information on the use of acoustic hangers, considerations for a correct selection and benefits in acoustic insulation click here.

AMC-MECANOCAUCHO has developed a mobile app called Acoustic hanger pro that allows engineers to make their own calculation and selection of the acoustic hanger or floor mount. This calculation software provides calculations of vibration isolation efficiency requiring simple information as:

  1. Distance between hangers/floor anti vibration mounts.

  2. Natural frequency required.

  3. Position of hangers/floor anti vibration mounts

“The app that allows you to select the acoustic hanger or floor mount that you need”

Following the box in box construction principle where floors and ceilings are decoupled, we must not forget about the walls. The structural noise travels also through walls, having an elastic wall tie avoids the transmission of vibrations through the wall.

“Structural noise also travels through the walls”

“Having an elastic wall tie avoids the transmission of vibrations through the wall.”

6.- Soundproofing Gyms in Hotels or adjacent to Hotels.

For those who work out regularly, constant traveling can throw a wrench into their routine. Hotels are adapting to a new “fitness trend” to attract customers, incorporating gyms in the Hotel. In some cases, hotel chains have gone a step further and hired in-house personal trainers.

Marketing actions to attract this public, threaten the stay of other customers. It is not unusual to see reviews complaining about the noise generated by the gym, either on the same hotel or adjacent to it.

72.jpg

73.jpg

74.jpg

75.jpg

“Box in box” concept shall be applied also for Gyms, so there is no transmission of noise through the structures.

76.jpg

Technical review of vibration isolation of Gyms, main areas to be isolated.

For a very reduced cost, additional measures as decoupling Gym equipment can improve considerably the acoustic insulation within gyms. Some examples are shown below. Apart from this an extensive article on the acoustic insulation of gyms is available by clicking on this link.

Vibrabsorber+Sylomer® Spring anti vibration mounts supporting plattfoms incorporating Sylodamp and granulated rubber for impact/damping isolation.

In high rise hotels where slabs are not thick enough, a good strategy for improving the acoustic insulation is the floor isolation, with low natural frequency floating floor anti vibration mounts. Vibrabsorber+Sylomer® anti vibration mounts are an adequate solution for supporting this type of floor.

82.jpg

Case study of gym floor isolation on high rise hotels.

7.- Lift/Elevator acoustic insulation.

Lifts in hotels present the potential for intrusive noise and vibration to the dwelling units. The adverse noise and vibration can result from the lift equipment located in the machine rooms or the shafts. The impacts can be significant issues related to the acoustic insulation, sleeping conditions, and enjoyment in the hotel. In fact, noisy lifts are one of the most important sources of complains in Hotel reviews.

84.jpg

85.jpg

86.jpg

87.jpg

There are often challenges to identify the transmission path (airborne vs. structure borne) and how the transmission paths can be mitigated to reduce the noise and vibration. Issues relating to the reliability and safety of the elevator operation can introduce difficulties and conflicts with implementing vibration isolators.

From a structural noise point of view the following areas should be addressed:

A.- Engine.

B.- Interaction of Rails and lift cabin guide.

C.- Fastening of the rails to the Building.

D.- Decoupling electrical current noise generation.

E.- Hydraulic pipes should be decoupled.

From an airborne noise point of view the following areas should be addressed:

A.-Lift doors.

B.-Door enunciators.

C.-Lubrification of mechanical components.

D.-Machinery encapsulated with Akustikabsorber® material, helps to reduce noise emissions.

The below cross section can show the type of soundproofing solutions that lead to noise and vibration mitigation.

8.- Acoustic insulation of extraction fans in Bathrooms.

Bathroom moisture extraction loud fans that result in guest complaints.

89.jpg

90.jpg

91.jpg

92.jpg

Fans become eccentric as time goes by due to mechanic wear and powder being settled on the wings of the fan.

A cost effective way to reduce this noise is by decoupling the moisture extraction fans. This way the vibrations that come from the eccentricity of the fan are not transmitted to the drywall ceiling that acts as a resonator. The acoustic insulation of this type of fans is recommended if the fan must stay on running long after the light has been switched off.

93.jpg 94.jpg

95.jpg

Akustik ventilator+Sylomer® allows to decouple the extraction fan of a bathroom, improving the acoustic insulation.

9.- Stairs and corridors.

Noisy stairs are another source of noise that causes claims in Hotels. This stepnoise can be decoupled and provide extraordinary acoustic insulation results.

98.jpg

99.jpg

100.jpg

101.jpg

There ready made products that allow an easy installation and provide effective results. An example of this is the Sylomer® SB-10

102.jpg

103.jpg

104.jpg

Sylomer SB-10 can decouple stairs, with low cost and optimal acoustic insulation results.

10 .- Acoustic insulation of TV’s and loudspeakers.

A cost effective way to reduce the structural noise of a TV or a loudspeaker is by decoupling through elastic elements such an acoustic hanger. This way the vibrations remain on the loudspeaker or TV and does not travel to the structure as ground borne noise.

Hotel guests with hearing difficulties watching endless Action film can make ruin the hotel experience. Since noise can be transmitted through the wall to the adjacent room. Anti vibration mounts that decouple the TV are the correct measure to reduce the structure borne noise transmission. An example of this type of product can be seen.

Acoustic hangers that provide an isolation to low frequencies (Spring) and high frequencies (Sylomer®) provide good results avoiding that neigbours hear announcements of the supermarket through the structure of the building. An example of this product is the ST+Sylomer® acoustic hanger specially designed for suspension of loudspeakers.
