A sound level meter (also called sound pressure level meter (SPL)) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. [1]
Dynamic range is a measure of how small you can measure a signal relative to the maximum input signal the device can measure. Expressed in decibels, the dynamic range is 20 log (Vmax/Vmin). For example, a device with an input range of ±10 V and a dynamic range of 110 dB will be able to measure a signal as small as 10 μV.
An audio analyzer is a test and measurement instrument used to objectively quantify the audio performance of electronic and electro-acoustical devices. Audio quality metrics cover a wide variety of parameters, including level, gain, noise, harmonic and intermodulation distortion, frequency response, relative phase of signals, interchannel crosstalk, and more.
Specific implementations may or may not be based on an actual sound level meters. Clap-o-meters were a popular element in talent shows and television game shows in the 1950s and 1960s, most notably Opportunity Knocks, [1] but have been since been supplanted by other, more sophisticated, methods of measuring audience response.
Smaart was unusual because it helped audio professionals such as theatrical sound designers do what was previously possible only with highly sophisticated and expensive measurement devices. [23] Audio system engineers from Clair Brothers used Smaart to tune the sound system at each stop during U2's PopMart Tour 1997–1998. [24]
A peak meter is a type of measuring instrument that visually indicates the instantaneous level of an audio signal that is passing through it (a sound level meter).In sound reproduction, the meter, whether peak or not, is usually meant to correspond to the perceived loudness of a particular signal.
