Without Acoustic Treatment With Acoustic Treatment

Restaurant noise build-up

The sounds and images shown in this example portray a restaurant, with people having dinner, moving and talking generating a background noise, in an untreated and a treated restaurant space.

This restaurant has 100 m² (a volume of 300 m³).

Untreated restaurant

Background noise created by multiple conversations and people moving will quickly build-up, making it very hard for people to understand each other. Consequently, people need to raise their voices above background noise levels, consequently increasing noise, in what is known as the Lombard effect, causing discomfort to both clients and workers.

Treated restaurant

Reverberation in the restaurant and noise build-up are both being controlled by the use of acoustic treatment in the ceiling and the walls. This way, speech intelligibility is improved and the sound environment becomes more enjoyable.

For this restaurant's ceiling treatment are being used 24 ViCloud VMT, which is a simple and lightweight suspended acoustic solution that presents twice the area of absorbing material exposed than a common acoustic panel. The walls are being treated with sound-absorbing panels extremely efficient in middle and high frequencies, using 8 VicShape 3D, 11 VicStrip Double and 12 Flat Panel VMT with VicSpacer Plus.

Acoustic Simulation Software Using Vicoustic's Panels 

The designs and simulations presented here were executed with the help of a tool from Odeon, a software we also use to create our acoustic simulation proposals. The simulations were developed using the estimated results obtained by using Vicoustic's acoustic panels recommended for this space.

An acoustic simulation can be requested with this type of software, which will analyze acoustic parameters such as reverberation time, speech transmission index, clarity, etc. Auralization with sound examples is not included in the projects. It is presented here solely as a demonstration.
