building acoustics and noise management

Peaceful urban park paths may still have sound levels above 45 dBA.

45 dB

45 decibels is the sound level recognized internationally as an upper limit for human comfort in residential interior spaces.  Exceeding the 45 dBA limit is not permitted by most building codes, planning regulations and noise ordinances. 

Ordinary people desire the ambient sound level to be less than 45 dBA.  As the sound level increases, it is generally recognized that physiological stress also increases.  An urban street with trucks, buses and motorcycles usually exceeds 75 to 80 decibels.
