In acoustics, absorption is what happens when sound waves are absorbed by a surface, as opposed to bouncing off the surface (reflection). Absorptive materials in a control room, for example, tend to “ [..]

This term describes a perfect polarity between an original signal (into the microphone) and the reproduced signal (through the speaker). When positive pressure exerted upon the microphone is translate [..]

A device that measures the acceleration to which it is subjected and creates an electric signal to match it. In music and audio, accelerometers are found in such things as microphones and guitar picku [..]

Named for its acorn-like shape, an acorn tube is a small vacuum tube used in ultra high frequency (UHF) electronics such as tube amplifiers.

The science of the sound—more specifically, the science of the properties and behavior of sound waves. A good understanding of acoustics is essential to audio engineering and studio design.

The part of a musical instrument that vibrates in response to the initial vibration of the instrument, causing the surrounding air to move more efficiently and making the sound louder. For example: th [..]

A room designed with hard, non-parallel surfaces to create reverberation. In recording studios, they are used to add natural reverb to a dry signal.

A component that is designed with the ability to control electrical current (as opposed to a “Passive Device”). In the recording studio, active devices are generally components that include an amplifi [..]
