Abstract text:
The sound field perceived within an enclosure is very different from that in an open space, due to the existence of two overlapping fields, direct and reverberant, which cause an increasing of the sound intensity level. A good understanding of the audition rooms design prescriptions and the purpose for which these were designed lead to a proper acoustic comfort in the interior space of the hall. Each audition hall is conceived with a specific purpose, for a certain type of activity. Thus, every room intended for music or speech performances should be treated differently from an acoustical standpoint. Although cinema and chamber music halls are designed for different values of the acoustical parameters, both must ensure sound clarity and quality according to the current design standards requirements. This paper investigates the possibility of using a cinema as a chamber music hall without compromising its acoustical properties. Thus, reverberation time values were determined in order to give a practical solution to this extent.
Key Words:
sound absorption; reverberation time; acoustic treatment.
