第一篇
Can you hear this?
When something creates a sound wave in a room or an auditorium (禮堂)listeners hear the sound wave directly from the source. They also hear the reflections as the sound bounces off the walls, floor, and ceiling . These are called the reflected wave or reverberant (反射的) sound, which can be heard even after the sound is no longer coming from the source .
The reverberation time of an auditorium is determined by thevolume or interior size of the auditorium .It is also determined by how well orhow poorly the walls, ceiling, floor, and contents of the room (including thepeople) absorb sound. There is no ideal reverberation time .The full-soundperformance of music such as Wagner operas or Mahler symphonies should have along reverberation time. The light, rapid musical passages of Bach or Mozartneed a reverberation time somewhere between.
Acoustic problems often are caused by poor auditorium design .Smooth , curved (彎曲的)reflectingsurfaces create large reflections . Parallel (平行的)walls reflect sound back andforth, creating a rapid ,repetitive pulsing(有節(jié)奏的跳動)effect. Large pillars (柱)andcorners can cause acoustic shadows as the sound waves try to pass around theobject . Some of these problems can be solved by using absorbers and relectorsto change the reverberation time of a room .For example , hanging largereflectors , called clouds , over the performers will allow some soundfrequencies to reflect and others to pass yo achieve a pleasing mixture ofsound.
