The circuit shows the peak level of the audio input using MOSFET Op-Amp. Audio level meters are designed to allow the optimum setting of input level for various sound functions. It utilizes a Metal ...

An instrument for measuring the level of sound pressure in DECIBELs. Such measurements are called sound level readings. See: SOUND LEVEL. Sound level meters usually ...

An example of a digital meter that was designed to display both VU standard response and peak tracking. Some excellent articles have appeared lately on the history and use of audio level meters in ...

Given its appearance in one form or another in all but the cheapest audio gear produced in the last 70 years or so, you’d be forgiven for thinking that the ubiquitous VU meter is just one of those ...

The unbridled development of radio broadcasting in the 1920s and 1930s demonstrated the need to standardize audio equipment, studio-to-transmitter links, and methods for measuring static and dynamic ...

Establishing and keeping to a standard audio level, especially in studios, has been a problem since the first radio station went on the air. Back in the 1960s, audio console output levels were usually ...

An instrument for measuring the level of sound pressure in decibels. Such measurements are called Sound Level readings. See: Sound Level. Sound level meters usually ...

This sound level meter circuit can be used to control the intensity of a sound recording or in a disco. It has 5 measurement domains between 70 and 120 dB; reading accuracy is 0.5 dB. Microphone M1 is ...
