WebMaximizing Gain-Before-Feedback in Your Sound System: A Webinar. In this hour-long webinar, we will look at tips, tools, and techniques for maximizing gain-before-feedback, and bust some myths about less helpful approaches. Back by popular demand, this webinar addresses one of the most frustrating audio issues for both musicians and engineers. WebStudy sample: Twenty adults (22-46 years) with normal hearing participated in gain measurement testing. Thirty adults (22-39 years) with normal hearing provided ratings of sound quality. Results: Mean additional gain before feedback for 2000-4000 Hz ranged from 5 to 16 dB across manufacturers. In live sound mixing, gain before feedback (GBF) is a practical measure of how much a microphone can be amplified in a sound reinforcement system before causing audio feedback. In audiology, GBF is a measure of hearing aid performance. In both fields the amount of gain is measured in decibels at or … See more In live sound mixing, GBF is dependent on a wide variety of conditions: the pickup pattern (polar pattern) of the microphone, the frequency response of the microphone and of the rest of the sound system, the number of active … See more A hearing aid incorporates a miniature microphone and a very small speaker driver, and various conditions may increase or decrease the amount of gain that can be applied … See more • HyperPhysics: Potential Acoustic Gain.
