Community Noise Equivalent Level

Add links
From Wikipedia, the free encyclopedia

Community Noise Equivalent Level (CNEL) is a weighted average of ambient noise level over time,[1] used in the US state of California to compare the noisiness of neighborhoods. CNEL is frequently used in regulations of airport noise impact on the surrounding community.[2][3] A CNEL exceeding 65 dB is generally considered unacceptable for a residential neighborhood.
