PART 2Levels of Sound
2.1 The following definitions apply in this Part.
- A-weighted sound pressure level
A-weighted sound pressure level means a sound pressure level as determined by a measurement system that includes an A-weighting filter that its manufacturer represents as meeting the requirements set out in the International Electrotechnical Commission International Standard IEC 61672-1:2002(E), 1st edition 2002-2005 Electroacoustics – Sound Level Meters. (niveau de pression acoustique pondérée A)
dBA means decibel A-weighted and is a unit of A-weighted sound pressure level. (dBA)
- noise exposure level (Lex,8)
noise exposure level (Lex,8) means 10 times the logarithm to the base 10 of the time integral over any 24-hour period of a squared A-weighted sound pressure divided by 8, the reference sound pressure being 20 μPa. (niveau d’exposition (Lex,8))
- sound level meter
sound level meter means a device for measuring sound pressure level that its manufacturer represents as meeting the performance requirements for a Type 2 instrument as specified in the International Electrotechnical Commission International Standard IEC 61672-1:2002(E), 1st edition 2002-2005 Electroacoustics – Sound Level Meters. (sonomètre)
- sound pressure level
sound pressure level means 20 times the logarithm to the base 10 of the ratio of the root mean square pressure of a sound to the reference sound pressure of 20 μPa, expressed in decibels. (niveau de pression acoustique)
- SOR/2019-246, s. 354(E)
Measurement and Calculation of Exposure
(a) is recommended for that measurement in clause 4.3 of CSA Standard CAN/CSA-Z107.56-13, Measurement of Noise Exposure; and
(b) is certified, by a certification body accredited by the Standards Council of Canada to grant the certification, as meeting the requirements for such an instrument set out in clause 4 of that Standard.
(2) The exposure of an employee to sound shall be measured in accordance with clauses 5, 6.4.1, 6.4.4, 6.5.2, 6.5.4, 6.6.2 and 6.6.4 of the Standard referred to in paragraph (1)(a).
(3) For the purposes of this Part, the measurement and calculation of the noise exposure level (Lex,8) to which an employee is exposed shall take into account their exposure to A-weighted sound pressure levels of 74 dBA and greater.
(4) For the purposes of this Part, the measurement and calculation of the noise exposure level (Lex,8) may also take into account the exposure of the employee to A-weighted sound pressure levels that are less than 74 dBA.
- SOR/2018-247, s. 3
2.3 (1) If an employee may be exposed, to an A-weighted sound pressure level equal to or greater than 84 dBA for a period that is likely to endanger the employee’s hearing, the employer shall, without delay,
(2) The measurement of the A-weighted sound pressure level shall be performed instantaneously, during normal working conditions, using the slow response setting of a sound level meter.
(3) In the investigation referred to in subsection (1), the following matters shall be considered:
(a) the sources of sound on board the aircraft;
(b) the A-weighted sound pressure levels to which the employee is likely to be exposed and the duration of such exposure;
(c) the methods being used to reduce the exposure;
(d) whether the exposure of the employee is likely to exceed the limits established by paragraph 2.4(a); and
(e) whether the employee is likely to be exposed to a noise exposure level (Lex,8) equal to or greater than 84 dBA.
(4) On completion of the investigation and after consultation with the work place committee or the health and safety representative, the person appointed to carry out the investigation shall write, sign and date a report setting out their
(a) observations respecting the matters considered under subsection (3);
(b) recommendations respecting the measures that should be taken in order to comply with sections 2.4 to 2.8; and
(c) recommendations respecting the use of hearing protectors by employees who are exposed to a noise exposure level (Lex,8) equal to or greater than 84 dBA but not greater than 87 dBA.
(5) The report shall be kept by the employer at a location accessible to affected employees for a period of 10 years after the date of the report.
(6) If it is stated in the report that an employee is likely to be exposed to a noise exposure level (Lex,8) equal to or greater than 84 dBA, the employer shall, without delay,
(a) provide the employee with written information describing the hazards associated with exposure to high levels of sound;
(b) make the report readily available to the employee; and
(c) post and keep posted in a conspicuous place at a location accessible to the employee a notice stating where the report may be reviewed.
