  2. Sound level meter - Wikipedia

    en.wikipedia.org/wiki/Sound_level_meter

    A noise dosimeter (American) or noise dosemeter (British) is a specialized sound level meter intended specifically to measure the noise exposure of a person integrated over a period of time; usually to comply with Health and Safety regulations such as the Occupational Safety and Health (OSHA) 29 CFR 1910.95 Occupational Noise Exposure Standard ...

  3. Acoustical measurements and instrumentation - Wikipedia

    en.wikipedia.org/wiki/Acoustical_measurements...

    Analysis of sound and acoustics plays a role in such engineering tasks as product design, production test, machine performance, and process control. For instance, product design can require modification of sound level or noise for compliance with standards from ANSI, IEC, and ISO. The work might also involve design fine-tuning to meet market ...

  4. Sound pressure - Wikipedia

    en.wikipedia.org/wiki/Sound_pressure

    The main instrument for measuring sound levels in the environment is the sound level meter. Most sound level meters provide readings in A, C, and Z-weighted decibels and must meet international standards such as IEC 61672-2013.

  5. Noise measurement - Wikipedia

    en.wikipedia.org/wiki/Noise_measurement

    When sound levels reach a high enough intensity, the sound, whether it is wanted or unwanted, may be damaging to hearing. [3] Environmental noise monitoring is the measurement of noise in an outdoor environment caused by transport (e.g. motor vehicles, aircraft, and trains), industry (e.g. machines) and recreational activities (e.g. music).

  6. A-weighting - Wikipedia

    en.wikipedia.org/wiki/A-weighting

    A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio). A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level. [1]

  7. Sound intensity level - Wikipedia

    en.wikipedia.org/wiki/Sound_intensity

    In consumer audio electronics, the level differences are called "intensity" differences, but sound intensity is a specifically defined quantity and cannot be sensed by a simple microphone. Sound intensity level is a logarithmic expression of sound intensity relative to a reference intensity.

    An experiment measuring noise decibels on the London Underground has revealed that tube trains can be louder than a music concert at its top speed.. The Victoria Line has been dubbed London’s ...

  9. Noise dosimeter - Wikipedia

    en.wikipedia.org/wiki/Noise_dosimeter

    With the accuracy of a type 2 sound level meter, a majority of noise dosimeters measure within ±2 dB A. One must make sure to the noise dosimeter is properly calibrated and kept out of extreme temperature and humidity. The noise dosimeter is typically programmed by a hearing conservationist, sound engineer or audiologist.
