Reverberation time is a measure of the time required for the sound to "fade away" in an enclosed area after the source of the sound has stopped. When it comes to accurately measuring reverberation time with a meter, the term T 60 [6] (an abbreviation for reverberation time 60 dB) is used.
Helmholtz resonator, p. 121, fig. 32. On the Sensations of Tone as a Physiological Basis for the Theory of Music (German Die Lehre von den Tonempfindungen als physiologische Grundlage für die Theorie der Musik), commonly referred to as Sensations of Tone, is a foundational work on music acoustics and the perception of sound by Hermann von Helmholtz.
Sympathetic resonance has been applied to musical instruments from many cultures and time periods, and to string instruments in particular. In instruments with undamped strings (e.g. harps, guitars and kotos), strings will resonate at their fundamental or overtone frequencies when other nearby strings are sounded.
Spring reverb, created with a series of mounted springs, is popular in surf music and dub reggae. Shimmer reverb, which alters the pitch of the reverberated sound, is often used in ambient music. Convolution reverb uses impulse responses to record the reverberation of physical spaces and recreate them digitally. Gated reverb became a staple of ...
Block diagram of the signal-flow for a common feedback loop. [1]: 118 Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
Myhill's property is the quality of musical scales or collections with exactly two specific intervals for every generic interval, and thus also have the properties of cardinality equals variety, structure implies multiplicity, and being a well formed generated collection. In other words, each generic interval can be made from one of two ...
