Noise Impact Analysis

Noise Impact Analysis

Noise standards for land use compatibility are stated in terms of the Community Noise Equivalent Level (CNEL) and the Day‐Night Average Noise Level (Ldn). CNEL is a 24‐hour weighted average measure of community noise. CNEL is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to

Decibel Noise and Range Charts

Decibel Noise and Range Charts

Decibel (dB) Range Charts - Click to Enlarge. Decibel (dB) is the unit used to measure a sound's strength. The decibel scale is not linear but logarithmic. This means that noise levels can't be added directly like other numbers. On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB
