What is the gain of the feedback suppressor of voice?.

Feedback Destroyer is a dedicated sound system for acoustic feedback suppression, a device to eliminate howling. .The so-called gain of the feedback suppressor of voice (GT) is the sound pressure level of the audience and the microphone at the sound pressure level difference. .Sound transmission directly affects the size of the gain and efficiency of quality sound reinforcement, sound system requirements in many circumstances there is sufficient volume, the volume of the audience can not hear faint, so that the transfer of information and music, artistic influence greatly reduced. .According to the definition of sound transmission gain can be expressed as: P audience for the sound pressure on the audience; P microphone to the microphone at the sound pressure; P0 as the standard sound pressure. .On a good sound system, its sound transmission gain must be greater than-6dB or more. .Sound transmission gain and sound reinforcement equipment, sound reinforcement environments, the sound field is closely related to the layout..
