2. Noise measurement - Wikipedia

   en.wikipedia.org/wiki/Noise_measurement

   Noise measurement can also be part of a test procedure using white noise, or some other specialized form of test signal.In audio systems and broadcasting, specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the inconsistent spectral distribution and temporal properties of the noise that they generate.

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 ...

5. Noise-figure meter - Wikipedia

   en.wikipedia.org/wiki/Noise-figure_meter

   A noise-figure meter could automate that procedure as follows: A gated broadband noise source (such as an avalanche diode) drives the device under test. A measurement is made with the noise source on; another measurement with the noise source off. From those measurements and the characteristics of the noise source, the noise figure can be ...

7. 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 ...

8. Loudspeaker measurement - Wikipedia

   en.wikipedia.org/wiki/Loudspeaker_measurement

   For a multiple sound source speaker system, the measurement should be carried out for all sound sources (woofer, bass-reflex vent, midrange speaker, tweeter...). These measurements are easy to carry out, can be done at almost any room, more punctual than in-box measurements, and predicts half-space measurements, but without directivity information.

9. Equal-loudness contour - Wikipedia

   en.wikipedia.org/wiki/Equal-loudness_contour

   The first research on the topic of how the ear hears different frequencies at different levels was conducted by Fletcher and Munson in 1933. Until recently, it was common to see the term Fletcher–Munson used to refer to equal-loudness contours generally, even though a re-determination was carried out by Robinson and Dadson in 1956, which became the basis for an ISO 226 standard.
