ABSTRACT

Acoustics for restaurants in Brazil – Overview and a Study case

Brazil is known as a country with rich and varied gastronomy. Studies from 2022 indicate that exists about 736 thousand restaurants in Brazil, and 56% were opened in the last three years. In São Paulo, the largest city in the country and elected by Traveller’s Choice as the seventh best gastronomic destination in the world is possible to find about 12,500 restaurants, with 52 different types of cuisine. Most of these restaurants do not have good acoustic conditions and are considered very noisy. This condition worsens comfort conditions and, according to studies, negatively affects even how we taste food. This work will present solutions implemented in some restaurants from São Paulo, with emphasis on a case study of a restaurant in operation, with the use of clean solutions and quick implementation. Field tests of room acoustic parameters were carried ou before and after the renovation. The acoustic comfort was evaluated by users after the renovation and some of the results are going to be presented.
