3Acoustic enhancement — is a subtle type of sound reinforcement system used to augment direct, reflected, or reverberant sound. While sound reinforcement systems are usually used to increase the sound level of the sound source (like a person speaking into a microphone,… …
4Acoustic Research — was a Cambridge, Massachusetts based company that manufactured high end audio equipment. The brand is now owned by Audiovox. Acoustic Research was well known for the AR 3 series of speaker systems, which used the 12 inch (305 mm) acoustic… …
5feedback — /feed bak /, n. 1. Electronics. a. the process of returning part of the output of a circuit, system, or device to the input, either to oppose the input (negative feedback) or to aid the input (positive feedback). b. See acoustic feedback. 2. the… …
6Acoustic Emission — (AE) is a naturally occurring phenomenon whereby external stimuli such as mechanical loading generate sources of elastic waves. AE occurs when a small surface displacement of a material is produced. This occurs due to stress waves generated when… …
7Acoustic lubrication — Acoustic or sonic lubrication occurs when sound (measurable in a vacuum by placing a microphone on one element of the sliding system) permits vibration to introduce separation between the sliding faces. This could happen between two plates or… …
8Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… …
9Sound reinforcement system — A sound reinforcement system is an arrangement of microphones, electronic signal processors, amplifiers, and loudspeakers that makes live or pre recorded sounds usually music or speech louder, or that distributes the sound to a larger or more… …
10Audio feedback — (also known as the Larsen effect after the Danish scientist, Søren Larsen, who first discovered its principles) is a special kind of positive feedback which occurs when a sound loop exists between an audio input (for example, a microphone or… …
