Auralisation demos

Demonstration videos comparing the audible noise in a hotel room, with Timber joist structure, which has a very noisy nightclub just above.
 

INTRODUCTION

A newly built or renovated building must comply with acoustic requirements depending on the country they are built in or the acoustic demands they must fulfil. These are put in place to give an improved living quality of their owners and prevents them being disturbed by problematic noisy neighbours.

Depending on the country, the quantity of wooden structure buildings may be important, especially those ones placed in the historic side of the city. They usually are light buildings that have limitations regarding the amount of load their structure can withstand, so the acoustic isolation solution cannot incorporate heavy concrete based solutions as floating floors. In these cases we have to give priority to dry construction solutions.

Achieving good noise insulation values with light structures is often a challenge. The transmission of noise through a rigid structures (structure borne noise) in these type of buildings plays a major role. In order to find easy constructive methods with the lowest cost-factor, AMC Mecanocaucho® has been working together with acoustic labs in order to obtain test results that can meet the acoustic demands of the most demanding countries.

This article shows the tests results for floating floor and hanging ceiling installations for light wooden structures, compared to a solution without isolation elements. Tests have been carried out using different solutions, either on the floor suspension, on the ceiling or combining both systems.

DEMONSTRATION VIDEOS MADE WITH AIHEAR



These videos have been created using the auralisation tool AiHear by NDY Acoustics. It models room effects and filters audio to demonstrate how diferent noise reducing materials will sound.

You are in a hotel room with a loud nightclub on the floor above. The acoustic effects of varying the floor and ceiling construction are demonstrated by exploring the different videos. To calibrate your audio playback level, adjust the volume on your device so that this conversation plays at a normal level.

These videos are best played trough headphones with a flat frequency response. Unevenness in the frequency response of your playback system may alter your audio perception of these videos. Setting the playback level of your device too loud or too quiet may also alter your perception of these videos.

INTRODUCTION

Cross Laminated Timber (CLT) framing is made of layers of wood boards that are glued together. The boards of each layer are oriented perpendicular to the adjacent layers, so similar structural properties can be obtained in both directions.


In general, wooden structures are more difficult to soundproof due to their relatively low mass compared to concrete structures, making the proper selection of sound insulation products critical.

INTRODUCTION

The majority of buildings use concrete structures as the base material for the construction of different works. It is a low-priced material compared to steel, with a resistance similar to or greater than that of brick, which offers the possibility of building elements of almost any shape.

For this study, a range of tests have been carried out using different solutions for floating floor and the suspended ceiling installations with different types of supports.

The tests were carried out by the National Research Council (NRC) of Canada.
