Reverberation
Reverberation
Reverberation: The persistence of a sound in a big hail due to repeated reflections from the walls, ceiling and floor of the wall is known as reverberation. A short reverberation is desirable in a concert hall, where music is being played, as it boosts the sound level. But excessive reverberation is highly undesirable because sound becomes blurred, distorted and confusing due to overlapping of different sounds. To reduce reverberation, the roof and walls of the auditorium are generally covered with sound absorbent materials like compressed fibre board, rough plaster or draperies. The seat materials are also selected on the basis of their sound absorbing properties.
Application of reverbartion:
The phenomenoen of reverbration is utilized by the producers of living or recorded music in order to enhance sound quality.Several systems have been developed to produce and simulate reverbartion. A similar device is aplate reverberator, where a metal plate is used to produce vibartions instead of a loudspeaker.
Advantages of reverberation :
Reverberation do wonders when it comes to musical symphonies and orchestral halls, when the right amount of reverbartion is present, the sound quality gets enhanced drastically.
Disadvantages of reverberation :
Multiple reflection of sound sometimes results in inability of the listener to listen clearly .This is because he tends to hear both the direct sound and the repeated reflected sound waves.
