You cannot "measure" the subjective loudness feeling in decibel with a "dB"-meter. You can measure the objective sound pressure with a "sound pressure meter" that shows the sound pressure in pascals or the sound pressure level SPL in dB or dBA.
The amount of deflection of a membrane held taut, being bombarded by the sound wave, is one indication of the loudness. The ear drum is another sensor.
Decibles (db)
What is the unit for volume or loudness
An oscilloscope is the machine, but it measures frequency.... so sound waves are measured by frequency
Hertz (cycles/second) measures frequency or pitch. Decibels measures loudness or sound pressure.
Ithink the answer is amplitude
"A sound meter measures the pressure of sounds. It is used in measuring the amount of noise pollution, such as aircraft noise. The sound meter does not measure the amount of sound that humans hear. There is a different type of meter used for this."

A uterine sound measures uterine depth.

An oscilloscope.
decibles
decibels
measured by a ruler lol
dicibels is the unit that measures the loudness of sound.
