How is a sound level meter used?

sound-level meter, device for measuring the intensity of noise, music, and other sounds. A typical meter consists of a microphone for picking up the sound and converting it into an electrical signal, followed by electronic circuitry for operating on this signal so that the desired characteristics can be measured.

How do you measure sound level?

If you are measuring the loudness of a specific machine, stand as far away from the machine as the longest dimension of that machine. For example, if the machine is 6 feet long, take sound level readings from 6 feet away from any part of that machine.

What is the difference between a sound level meter and a dosimeter?

Use Sound Level Meters when you need to know the noise level of a particular task or process, or how noisy a piece of machinery or area is. Use Noise Dosimeters when you need to find out the direct noise exposure of an employee.

What is an audio level meter?

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 manually set speaker levels?

Manually: Calibrate Surround Sound Levels with an SPL Meter

1. Set your receiver to 0dB volume.
2. Go into the System Setup menu of your AV receiver.
3. Navigate to the speaker setup submenu.
4. Select channel level or speaker level (in some receivers you need to enable the test tone)
5. Select the Left speaker.

What is an integrating sound level meter?

Definition: An integrating sound level meter is an instrument that measures sound energy over a period of time. When this is converted into a dB value (which makes it easier to shown on the display of a sound level meter) it is known as the Sound Pressure Level. This is where the term SPL comes from.

Is a dosimeter the same as a Geiger counter?

Geiger counters measure low levels of radiation, such as looking for surface contamination. Dosimeters can be in the form of a sticker, badge, pen/tube type, or even a digital readout. They all measure the total accumulated amount of radiation to which you were exposed.

How do I use the dB meter app?

With a free app and your Android phone, you can turn your phone into a noise meter and find out. Download Sound Meter from the Android Market and launch the app. It starts right up to the sound meter and measures the minimum, mean, and maximum ambient sound levels in decibels (dB).

How do I adjust the speaker level of my speakers?

Sit in the Prime Location The idea is to get each speaker to measure 75 dB SPL. Since the left and right speakers should form the foundation for your level-setting procedure, the first thing you want to do is raise the master volume of the AV receiver until the Left speaker measures 75 dB SPL on your meter.
