ITU-R 468 noise weighting

ITU-R 468 noise weighting is a standardized measurement technique used for assessing background noise levels in rooms, particularly in relation to audio and broadcast applications. This weighting is defined by the International Telecommunication Union (ITU) in its Recommendation ITU-R 468, which specifies a way to measure noise in environments where sound quality is critical, such as in studios, concert halls, or broadcasting facilities.
