Often referred to as a sound pressure level spl meter decibel db meter noise meter or noise dosimeter a sound level meter uses a microphone to capture sound.
Noise measurement device.
A useful tool for complete control.
Risepro decibel meter digital sound level meter 30 130 db audio noise measure device backlight max min data hold auto power off dual ranges ht 80a 4 3 out of 5 stars 439 21 90.
Noise measurement can also be part of a test procedure using white noise or some other specialised form of test signal.
A noise dosimeter is a small light device that clips to a person s belt with a small microphone that fastens to the person s collar close to an ear.
A sound level meter is used for acoustic sound that travels through air measurements.
Although it s not the right choice for anyone who needs to measure very high noise levels its maximum decibel levels are limited to 90 decibels by some devices this well rated app is a suitable tool for people who want to keep an eye on the general sound levels that they encounter throughout their day.
When you measure noise levels with a sound level meter you measure the intensity of noise called decibel units db.
Thus the pce 322a is an ideal real time noise measuring device as well as being useful for long term noise exposure monitoring over time.
The sound is then evaluated within the device and acoustic measurement values are displayed.
A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure.

A sound meter uses a display with a decibel range and resolution to approximate to the ear s dynamic range usually the upper range rather than the quiet part.
Gateway noise monitor status all data files can then be retrieved remotely from remote xl2 sound level meter even during an ongoing measurement.
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 the diaphragm of the microphone responds to changes in air pressure caused by sound waves.
Noise measurement data from studies in similar situations are very helpful in assessing the potential noise problem.
The dosimeter stores the noise level information and carries out an.
