Effect Of Equalizers On the Performance of Sound Systems

Abstract

The listener to a concert or the visitox: to a conference room often pronounces judgment. on the acoustic reproduction quality of a signal emitted by a natural source or via electro-acoustical devices. This judgment is often very imprecise, in terms such as " very good acoustic" or "poor intelligibility". Such assessments combine objective causes with subjective experiences acquired through listening to broadcast and television transmission as well as CD, DAT and other hi-fi reproduction. For speech one normally desires intelligibility in an atmosphere unaffected by the room or by the electro-acoustical means of amplification.
