Noise is undesirable and unwanted sound. Sound is measured in decibels (units of sound). The A-weighted sound level (i.e. dBA) has been found to correlate well with the perception of annoying sounds and is used to assess community and roadway noise. The generally-accepted sound level descriptor for community and roadway noise is the equivalent sound level (Leq). It is the sound level of the continuous sound, which would have the same sound energy as the actual time varying sound over the period of time being considered. Due to the time consideration, Leq has to be referenced to a specific time period. For community and roadway noise, the Ottawa Official Plan will use a 30 minute sound level time period which will be expressed as Leq (30 min).
