You are looking for a Sound Pressure Level (SPL) meter.
The meter will measure on a logarithmic scale in Decibels (dB) to give you a quantifiable numbers. You should look for one with both A and C weighting.
A sound level meter would be used to measure sound level, and the unit is in decibels, dB. You could also measure it with a microphone and oscilloscope, provided you could calibrate them against standard instruments.
to measure sound from distance use decibels
If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.
You measure the sound pressure with a sound pressure level meter (SPL meter).
Take a sound pressure level meter (SPL meter). Try to measure the sound pressure p.
