The second chapter in this section on Acoustics and Sound Reinforcement is also by Don and Carolyn Davis, and deals with the problem of equalizing the sound system and its associated acoustic environment to obtain the desired frequency response, and suitable freedom from feedback (or “ howlround ” ) and transient ringing. This topic is of fundamental importance, because if a system has an irregular and peaky gain response, the tallest peak will put the limit on how much gain can be used before feedback. If the response is smoothed then the overall gain can be increased at all frequencies and the system is not only being used with much greater efficiency, but its sound will be far more acceptable.

Don and Carolyn first examine the ...
