Which meter is used for measuring noise?

A Sound Level Meter (SLM) is an instrument (commonly hand-held) that is designed to measure sound levels in a standardized way. It responds to sound in approximately the same way as the human ear and gives objective, reproducible measurements of sound pressure levels.

How do you measure the noise level of a database?

To measure decibels, download a mobile decibel-reading app, like Sound Level Meter or Decibel Meter. You can also measure decibels using computer programs like Audacity or Decibel reader. Another option is to use a profession decibel meter, which can give you a very accurate decibel reading.

How does a noise meter work?

A decibel meter uses a microphone to capture sound. The mic captures sound pressure deviations and converts them into an electrical signal that is made stronger by a preamplifier. The decibel meter then uses signal processing to apply frequency and time weightings to the signal according to international standards.

What is a dB meter?

A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. 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.

What is a Class 1 sound meter?

A Class 1 Sound Level Meter is a sound measuring instrument that satisfies the IEC 61672-1 international standard’s performance criteria such as linear operating range, frequency response, and temperature operating range. Check the sound level meter price here. Class 1 SLM.

What is the difference between a Class 1 and Class 2 sound level meter?

But in simple terms: A Class 1 sound level meter is generally seen as more accurate than a Class 2 meter; and, A Class 1 sound level meter is able to measure sound over a wider frequency range than a Class 2 meter.

What is 50 decibels sound like?

50 dB is as loud as a quiet conversation, a quiet suburb, a quiet office, or a quiet refrigerator. Notice the use of the word ‘quiet’ when describing this noise level? That’s because all sounds between 31-60 decibels are considered quiet.
