Sound Level Meters: Electroacoustics - Sound level meters This is the most recent sound level meter standard and the one that modern measurement regulations will require.
Grades in order of accuracy: Class 1, Class 2: IEC Sound Level Meters: Specification for Sound Level Meters This standard has been superseded by IEC BY ORDER OF THE EXECUTIVE DIRECTOR Office of the Federal Register Washington, D.C.

A sound level meter is used for acoustic (sound that travels through air) measurements. It is commonly a hand-held instrument with a best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and diaphragm of the microphone responds to changes in air pressure caused by sound A-weighted equivalent: LAeq.

Noise shall be measured with a sound level meter meeting the standards of the American National Standards Institute (ANSI S1. ) "American Standard Specification for General Purpose Sound Level Meters." The instrument shall be set to the A-weighted response scale and the meter.
The frequency range covered by the requirements of this standard depends on the specific type of sound level meter or instrumentation being used, but, in general, the frequency content of the sound being measured should be contained within the range covered by the octave bands having center frequencies from Hz to kHz.
Real-time applications for our sound level meters include sound-system setups, music recording, and measurement of the noise produced by a machine or vehicle or typical of an environment.
Data logging sound level meters such as our DSMSD, DSMSD and DSM20 provide the documentation needed to prove compliance with regulatory limits on noise.

Sound level meters used by OSHA meet the American National Standards Institute (ANSI) Standard S (R) or S, “Specifications for Sound Level Meters.” These ANSI standards set performance and accuracy tolerances according to three levels of precision (Types 0, 1, and 2) and apply to noise dosimeters and sound level meter.

Sound level meters that measure frequency-weighted sound exposure levels. Sound level meters specified in this standard are intended to measure sounds generally in the range of human hearing. Two performance categories, class 1 and class 2, are specified in this standard.
Classes: IEC defines two performance categories, class 1 and. Mini size and affordable SPL (Sound Level) Meter is designed for quick testing of sound levels. At only 6" long, this SPL meter is very portable and can fit easily into a briefcase or tool bag. Utilizing a high quality ½” Electret Condenser Microphone that insures the.
A non-integrating sound level meter should only be used if the equipment in question produces a very steady-state (non-changing) sound level (this rarely occurs!). The meter should be configured so that there is no lower threshold cutoff (in order to capture the entire range of equipment sound levels.

Noise shall be measured with a sound level meter meeting the standards of the American National Standards Institute (ANSI S1 ) "American Standard Specification for General Purpose Sound Level Meters". The instrument shall be set to A-weighted response scale and at the meter to the slow response.
Measures shall be. A-weighting is the most commonly used of a family of curves defined in the International standard IEC and various national standards relating to the measurement of sound pressure level.A-weighting is applied to instrument-measured sound levels in an effort to account for the relative loudness perceived by the human ear, as the ear is less sensitive to low audio frequencies.
Equivalent sound level is an energy average that takes varying sound levels of a time period and describes them as one constant noise level (i.e., the total sound energy divided by the duration). It is a construction of that constant sound level containing the same acoustic energy as the varying sound level during the same time period.

Neither is suitable for the determination of the “average” value if the character of the sound is other than steady or is composed of separate periods of steady character.
If there is an ISO or IEC standard suitable for use in the United States and recommended by a U.S. technical advisory group (see Appendix C, p.
), the ASA standards committees may adopt the standard as written (or with minor changes) as an American National Standard (ASA, a). American standards can also be used as the basis for.
