sound level meter

Three years later these curves were used in the first American standard for sound level meters.

Some modern digital sound level meters can carry out this analysis automatically.

Sound level meters are also divided into two types in "the Atlantic divide".

There are three types of sound level meters.

A sound level meter is a device that measures the intensity of sound at a given moment.

Ambient noise level is measured with a sound level meter.

Specific implementations may or may not be based on an actual sound level meters.

Sound level meters of the two classes have the same functionality, but different tolerances for error.

This applies to both the sound level meter itself as well as the associated calibrator.

These are, these sounds are measured on an instrument called a sound level meter.

Basically, there are two different instruments to measure noise exposures: the sound level meter and the dosimeter.

One of the more difficult decisions in selecting a sound level meter is "How do you know if it complies with its claimed standard?

Live sound covers an enormous range of levels, but this is not something that can be demonstrated with a conventional sound level meter.

The A-weighting curve has been widely adopted for environmental noise measurement, and is standard in many sound level meters.

IEC standards divide sound level meters into two "classes".

To estimate employee noise exposures with a sound level meter it is also generally necessary to take several measurements at different locations within the workplace.

A sound level meter can also be positioned within the immediate vicinity of the exposed worker to obtain an individual exposure estimate.

This type of survey is normally completed using a sound level meter (SLM).

Acoustical measurements and instrumentation range from a handheld sound level meter to a 1000-microphone phased array.

A common variant of the sound level meter is a noise dosemeter (dosimeter in American English).

After appropriate sound level meter readings are obtained, people sometimes draw "maps" of the sound levels within different areas of the workplace.

Sound level meter calibrated to an equal-loudness contour of the human auditory system behind the human ear.

The current international standard that specifies sound level meter functionality and performance is the IEC 61672:2003.

The audio units each hold two back-up audiometers and sound level meters which are operated by qualified occupational health specialists.

Even the most accurate approved sound level meter must be regularly checked for sensitivity-what most people loosely call 'calibration'.
