Impact of the glazed roof on acoustics of historic interiors

Abstrakt

The paper discusses the adverse acoustic phenomena occurring in the semi-open interiors (courtyards, yards) covered with a glass roof. Particularly negative is the rever-beration noise, which leads to the degradation of the utility functions of the resulting spaces. It involves the drastically reducing the intelligibility of speech, loss of natural sounding of music, problems with the sound system, as well as disturbances in the voice alarm system operation. The work refers to historic interiors, where preservation requirements signifi-cantly limit the possibility to reduce reverberation noise by means of sound-absorbing materials of general use. The work describes the concept of the use of micro-perforated foil which is a modern, technologically advanced sound-absorbing material. Because of its high acoustical efficiency and negligible effect on the expression of architectural de-sign, micro-perforated foil is particularly suitable for the purpose in question.
