Technical Definitions “Ambient sound level” is the sound level that is present in the environment, produced by noise sources other than the source under impact assessment. See Background sound level;

“Background sound level” means Ambient sound level; “Class 1 Area” means an area with an acoustical environment typical of a major population centre, where the background noise is dominated by the urban hum. “Class 2 Area” means an area with an acoustical environment that has qualities representative of both Class 1 and Class 3 Areas, and in which a low ambient sound level, normally occurring only between 23:00 and 07:00 hours in Class 1 Areas, will typically be realized as early as 19:00 hours. Other characteristics which may indicate the presence of a Class 2 Area include:

•  absence of urban hum between 19:00 and 23:00 hours;
•  ambient sound level is defined by natural environment and infrequent human activity;
• and  no clearly audible sound from stationary sources other than from those under consideration.
