摘要:
The modern trend among architects to use curved walls in auditoriums brings into considertion the adjustments that are helpful in reducing the resultant echoes and concentrations. Coffering these curved surfaces breaks up the reflected sound somewhat, but usually leaves more or less concentrated echoes. The application of absorbing material in a checkerboard pattern, with bare wall between the absorbing pads is promising. The pads absorb sound and change the phase of the reflected waves which interfere with the waves from the bare spaces, so that this arrangement appears more effective than coffering.A more drastic treatment is to make the entire surface of grill work, whereby the incident sound passes through without reflection to a space behind the wall which may be used as the plenum chamber of the ventilation system. The appearance of the wall can be made satisfactory if the holes in the grills are not large, and if the surface is suitably decorated. This plan was tried in a New York auditorium with successful results, so that it now appears possible to use such curved walls, and allow architects freedom in the design of auditoriums with curved interiors.
