Adaptation of coutyards into covered and glazed atriums and its impact on the level of acoustic comfort inside – case study

Abstract

Increasingly popular, in the area of modernization or revitalization of historic buildings, is the creation of a roof that is often fully glazed over the inner courtyard, thus creating a new spacious interior capable of performing many functions. The acoustics evaluation undertaken in this article was carried out on the basis of measurements and simulation of reverberation time in The Home Army Museum building in Cracow.

Analysis on the Acoustics of an Auditorium

“…A classical concern with architectural acoustics is the measurement of reverberation time [21] [22], which is defined as the time needed for sound intensity to decrease to 10 −6 of its original strength, or for sound intensity level to decrease by 60 dB. [1] suggests that a higher reverberation time reduces intelligibility of speech, while a lower reverberation time makes the sounds made in the auditorium sound "dead".…”
