- Noise Abatement Society - The Noise Abatement Society (NAS) promotes ways to combat antisocial noise. The Society's annual John Connell Awards recognize local iniatives to address noise complaints.
- Marshall Day Acoustics - Acoustics and noise engineering consulting firm that provides acoustical, environmental noise, and noise control design services, including concert hall and auditorium design, environmental noise assessments, and building services and industrial noise control.
- Airport Noise Regulations, Buchanan Field Airport, Contra Costa County - Provides information about the noise ordinance and noise abatement procedures pilots are required to follow.
- Community Noise Strategy Plan - The CALM network will establish a Community Noise Research Strategy Plan based on the work and reports of expert Noise Working Groups appointed by the European Commission and in cooperation with the relevant industry sectors, research institutions and interest organisations. The aim is to clearly identify links and gaps between current noise abatement technology and future EU noise reduction and regulation goals in the fields of air traffic, road and rail transport, marine technologies and outdoor equipment.

- Effective input noise temperature - In telecommunications, effective input noise temperature is the source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source. If F is the noise figure numeric ...
- Noise (acoustic) - Acoustic noise, is any sound in the acoustic domain, both wanted (music, bird song, amplified speech, etc) and unwanted. Unwanted noise includes noise pollution in an otherwise quiet environment, unwanted noise on audio systems, appliance noise, factory noise, crowd noise and so on.
- Noise (radio) - Radio noise in radio reception is the superposition of white noise (also called "static") and other disturbing influences on the signal, caused either by thermal noise and other electronic noise from receiver input circuits or by interference from radiated electromagnetic noise picked up by the receiver's antenna. If no noise was picked up with radio signals, even ...
- Noise figure - In telecommunication, noise figure (NF) is a measure of degradation of the signal to noise ratio (SNR), caused by components in the RF signal chain. The noise figure is the ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature T_0 (usually 290 K).
- Pink noise - Pink noise or 1/f noise is a signal or process with a frequency spectrum such that the power spectral density is proportional to the reciprocal of the frequency. The name arises from being intermediate between white noise (1/f0) and red noise (1/f2, more commonly known as Brownian noise).
