What does a sound level meter do?

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.

What is a sound level meter called?

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.

How do you measure sound levels?

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).

What is a Type 1 sound level meter?

A Class 1 Sound Level Meter is a noise measurement instrument that meets the requirements of IEC 61672-1:2002 (or an equivalent such as BS EN 61672-1:2003) to Class 1 performance. Tolerances & Accuracy. This standard specifies two levels of performance, Class 1 and Class 2, with Class 1 being effectively more accurate.

How many decibels can kill you?

150 decibels is usually considered enough to burst your eardrums, but the threshold for death is usually pegged at around 185-200 dB. A passenger car driving by at 25 feet is about 60 dB, being next to a jackhammer or lawn mower is around 100 dB, a nearby chainsaw is 120 dB.

What is an acceptable noise level?

Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB. In general, sounds above 85 are harmful, depending on how long and how often you are exposed to them and whether you wear hearing protection, such as earplugs or earmuffs.

What level of sound is comfortable for a human?

A sound level of 0 dB is approximately the threshold of human hearing and is barely audible under extremely quiet listening conditions. Normal speech has a sound level of approximately 60 dB; sound levels above 120 dB begin to be felt inside the human ear as discomfort.

How do you measure dB sound?

Use a mobile app.

1. For Apple devices: Decibel 10th, Decibel Meter Pro, dB Meter, Sound Level Meter.
2. For Android devices: Sound Meter, Decibel Meter, Noise Meter, decibel.
3. For Windows phones: Decibel Meter Free, Cyberx Decibel Meter, Decibel Meter Pro.

What is dB sound?

Decibels measure sound intensity

Amplitude, reported on the decibel (dB) scale, measures its pressure or forcefulness. The more amplitude a sound has, the louder it is. The logarithmic decibel scale measures differently than a linear scale. ... If a sound is 20 dB, that's 100 times louder than near silence.

What does 10 decibels sound like?

Topic Overview

Are sound meter apps accurate?

The answer is, “Yes,” but only four apps that were tested measure up. The National Institute for Occupational Safety and Health (NIOSH) evaluated the apps at its acoustic testing lab. The tests also compared results for i-Phones and Android phones. ... No Windows phone noise apps met NIOSH's standards either.
