• (a) is chosen to best represent the situation causing disturbance;
• (b) is between 1 minute and 30 minutes;
• (c) is chosen to avoid influence from the residual sound where possible; and
• (d) may consist of a number of non-contiguous, short term measurement time intervals that add up to 1 to 30 minutes; “Medical Health Officer” means the Medical Health Officer appointed under the Public Health Act, SBC 2008, c. 28 or his/her designate, to act within the limits of the jurisdiction of any local board, or within any health district; “nighttime” means any period of any day not specifically defined as daytime; “point of reception” means a position within the property line of the real property occupied by the recipient of a sound that best represents the location at which that specific sound, emanating from another property, is received and the resulting disturbance experienced and is:
• (a) at least 1.2 m from the surface of the ground and any other sound reflecting surface; and
• (b) outdoors, unless there is no point of reception outdoors because the specific sound is within the same building or the wall of one premises is flush against another, in which case the point of reception shall be within the building where the specific sound is received and the resulting disturbance experienced; “premises” means
• (a) the area contained within the boundaries of a legal parcel of land and any building situated within those boundaries; and
• (b) each unit, the common areas of the building, and the land within the apparent boundaries of the legal parcel of land are each separate premises 6648716 Bylaw 8856 Page 4 where a building contains more than one unit of commercial, industrial or residential occupancy; “Quiet Zone” means those areas so described in this Bylaw and so indicated in Schedule

A, attached to and forming part of this Bylaw; “rating level” means the specific sound level plus the impulsive sound adjustment and tonal sound adjustment; “residential occupancy” in respect of premises, means a dwelling unit located within a building, and includes a room for rent in a hotel or motel; “residual sound” means the sound remaining at a given location in a given situation

when the specific sound source is suppressed to a degree such that it does not contribute to the total sound; “sound” means an oscillation in pressure in air which can produce the sensation of hearing when incident upon the ear; “specific sound” means the sound under investigation; “specific sound level” means the equivalent continuous sound pressure level or L eq at the point of reception produced by the specific sound over the measurement time interval; “tonal sound” means specific sound which contains one or more distinguishable, discrete, continuous tones or notes including, without limitation:
