Several Methods to Reduce Seat-Dip Effect
In this paper, the properties of the anomalous attenuation of low-frequency sound, namely the seat-dip phenomenon in auditoria, as well as the achievements in the researches on seat-dip effect in recent decades, are summed up, and the property of seat-dip effect in time domain is specially pointed out. Moreover, the influence of the seat-dip effect on the subjective perception of the audience is described. According to the results of some authors measurements and numerical simulation, several methods to reduce the sear-dip effect are finally introduced, such as setting seats on empty pit, mounting floor absorbers and raking seats, etc.
