  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. 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).

  4. 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 ...

  5. Audio noise measurement - Wikipedia

    en.wikipedia.org/wiki/Audio_noise_measurement

    Microphones, amplifiers and recording systems all add some electronic noise to the signals passing through them, generally described as hum, buzz or hiss. All buildings have low-level magnetic and electrostatic fields in and around them emanating from mains supply wiring, and these can induce hum into signal paths, typically 50 Hz or 60 Hz (depending on the country's electrical supply standard ...

    Measures AF signal level and noise Q meter: Measures Q factor of the RF circuits Tachometer: Measures speed of motors Signal analyzer: Measures both the amplitude and the modulation of a RF signal Signal generator: Generates signals for testing purposes Spectrum analyser: Displays frequency spectrum Sweep generator

  7. Noise (electronics) - Wikipedia

    en.wikipedia.org/wiki/Noise_(electronics)

    Examples of electrical noise-level measurement units are dBu, dBm0, dBrn, dBrnC, and dBrn(f 1 − f 2), dBrn(144-line). Noise may also be characterized by its probability distribution and noise spectral density N 0 (f) in watts per hertz. A noise signal is typically considered as a linear addition to a useful information signal.
