of units, the reference sound pressure for measuring ambient noise level is 0.0002 dyn/cm, or 0.00002 N/m. Most frequently ambient noise levels are measured using a frequency weighting filter, the most common being the

Ambient sound levels are often measured in order to map sound conditions over a spatial regime to understand their variation with locale. In this case the product of the investigation is a sound level
