Study and Improvement of Acoustic Conditions in Public Spaces of Shopping Malls

Acoustic comfort in shopping malls is one of the aspects that influence environment. Making enjoyable and comfortable retail public spaces demanded when designing managing properties. This paper focuses on study with a large volume operating malls, which are perceived as acoustically uncomfortable. The main reason for poor acoustic conditions too long reverberation, measured reverberation time reached 4–5 s at middle frequencies. usual way to improve acoustics apply sound-absorbing materials space surfaces. Two examples improving food courts given. In both cases, was reduced by about half, changes were considered significant positive. It shown Sabine’s equation valid spaces. Average absorption coefficients found means can be used quick estimation similar without absorbing treatment. Based analysis this other studies, method qualitative assessment proposed.
