“acoustic hailing device” means a device that was designed for communicating voice messages or other sounds over long distances and that is capable of emitting, or was designed to emit, sounds that are 135 decibels or greater when measured at a distance of one metre from the device, but does not include a siren that was designed to be mounted on a vehicle; (“dispositif à ondes acoustiques”)

“dBA” means a measure of sound level in decibels using a reference sound pressure of 20 micropascals when measured on the A-weighting network of a sound level meter; (“dBA”)

“decibel” means a unit of measurement of sound pressure level that is equal to 20 times the logarithm to the base 10 of the ratio of the pressure of a sound, divided by the reference pressure of 20 micropascals; (“décibel”)

“equivalent sound exposure level” is the steady sound level in dBA that is produced by an acoustic hailing device which, if a person were exposed to the sound level for eight hours in a day, would contain the same total energy as that generated by the actual and varying sound levels produced by the device to which the person is exposed in the day, determined in accordance with the following formula:

where,

Lex,8 is the equivalent sound exposure level in 8 hours,

Σ  is the sum of the values in the enclosed expression for all activities from i = 1 to i = n,

i  is a discrete instance in which a person is exposed to a sound level produced by an acoustic hailing device,

ti is the duration in hours of i,

SPLi  is the sound level of i in dBA,

n  is the total number of discrete instances in which the person is exposed to a sound level produced by an acoustic hailing device in a day. (“niveau d’exposition sonore équivalent”) O. Reg. 36/13, s. 1.
