A device used to measure sound and music loudness as expressed in decibels. See also sound pressure level.
a device that measures the intensity of sound at a given moment
a device used for the measurement of sound level, with standard frequency weighting and standard exponentially weighted time averaging
an instrument designed to give constant and objective measurements of sound level
an instrument designed to respond to sound in approximately the same way as the human ear and to give objective, reproducible measurements of the sound pressure fluctuations present at the measurement position
An instrument for the measurement of sound level. It consists of a microphone, a frequency selective amplifier and an indicator. It measures sound level in dB SPL.
A meter, usually handheld, that is used to measure sound pressure levels.
A meter that measures sound pressure levels, with or without frequency weighting, and with the option of fast or slow averaging times. See Frequency Weighting.
A device that measures, in dB, the amplitude of sound waves.
An instrument used for the measurement of noise in sound level surveys.
A device that measures the sound pressure levels.
An instrument which includes a microphone, amplifier, RMS detector, integrator or time averaging device, output meter, and weighting networks used to measure sound pressure levels.
A sound level meter measures sound pressure level. It has several frequency-weighted decibel (dB) scales (A, B, C) to cover different portions of the range of measured loudness. Sound level meters indicate RMS sound, unless the measurements are qualified as instantaneous or peak sound level.
A device used to measure sound pressure levels. Meters consist of a microphone, amplifier, output meter, and frequency-weighting protocols.
An instrument for measuring various noise parameters
An instrument used to measure sound pressure levels. Type 1 are precision instruments, whereas Type 2 are general purpose instruments.
A sound level meter is used to measure sound levels, usually in terms of subjective loudness. This involves the use of a weighting filter, usually to the A-weighting standard.
