Public Spaces Acoustic Treatment Guidelines / Restaurants Introduction One of the major acoustic issues in restaurants is the high level of background noise. Recently, a survey undertaken in UK* found that nearly 80% of people have left a restaurant, cafe or pub early because of noise. In addition, studies conducted by Zagat, an international dining guide, revealed that noise levels are the top complaint from those dinning out. Excess noise is considered even more annoying than poor service! Vicoustic has developed this new White Paper to help you find a solution to control the background noise...

Typically, new Restaurants have very hard, reflective surfaces, such as glass, concrete, plasterboard, among others. In such environments, sound is strongly reflected many times around a room's surfaces taking a long time before it is finally absorbed. This leads to very reverberant rooms. In such rooms, background noise created by multiple conversations will quickly build up, making it very hard for people to understand each other.

This will help minimize the noise 'build-up' process, making communication easier and will avoid people having to raise their voices to be heard and understood. However, it should be noted that lack of background noise in a restaurant will also result in an environment that potentially lacks atmosphere and mood - no...
