In Concert Halls, music or other sounds are produced on the stage and must be carried through the air to people in the crowd. Some of these sound waves go directly to the people in the crowd, without bouncing off of anything first. However, other sound waves from the stage first go to areas like walls and ceilings, then the sound either bounces off or is absorbed. When sound waves bounce off of a surface, the new direction they travel is related to the angle they strike the surface.
Thus, acoustical engineers and architects sometimes need to place panels on the ceilings (and/or walls) to reflect sound in a specific direction - back to the audience.
using panels that are curved have a similar effect.
At concert halls NOT at church
Accoustics.
Reverberation in concert halls is caused by diffraction.
publlic concert halls
From the vibration the bass gives off.
The ceiling of conference hall are curved so that after the light reflection reaches all corners of the hall, the room becomes bright.
In bass concert halls, the sound is amplified by the size of the open empty room. The sound reverberates off the walls to make it sound louder and deeper than it really is.
concert halls, stadiums, school halls, bandshell, bandstand and clubs, party's, evets- occoasions.
In concert halls the walls are made out of acoustic materials. The materials, as well as the amplifier may result in multiple echoes in a concert hall.
Reverberation! :)
Fields, theaters, stadiums, cinemas, concert halls etc.
Like 1/100 Venue Halls. Not most of the time.
