Noise surveys conducted

Montréal-Ouest:

• December 2008: Noise survey – Road component (study area of 300 metres from autoroute 20)

• November 2011: Cumulative noise impact – Road and rail components (study area of 300 metres from autoroute 20)

• 2017: Noise survey – Rail component (study area at more than 300 metres from autoroute 20)

13 Some information: Noise indicator

Noise level A-weighted Leq,24h (dBA) (L = Level and eq = equivalent) Indicator that cumulates all noise variations over a 24-hour period

Why use an indicator: • Mathematical expression used to represent a complex situation that varies in

time and space • Makes it possible to measure and compare the sound environment at different

geographical points, at different times of the day or year • Represents the impact of noise on a person’s health and discomfort

14

Noise scale

3 dBA barely perceptible variation 5 dBA perceptible variation 10 dBA double or halves noise level 55 dBA et - Recognized as an acceptable level

Noise levels do not ad up in a linear manner 2x noise sources ≠ 2x noise levels

Observations during noise readings (October 25-26, 2017)

2017: Noise impacts (study area at more than 300 metres from autoroute 20)

Area delimited by Brock, Carnavon, Ballantyne and Avon: • Noise from trains passing on CN railways is not the main source of noise • Passenger trains are barely or not audible • Freight trains are audible but noise is similar to ambient noise • Night: freight trains are more easily audible at night since noise levels from

roads are reduced

Mitigation measures

After the project

Current noise barrier

Planned noise barriers

Plantation of trees and shrubs

Addition of an absorptive

material currently being

analyzed

24 Noise follow-up: after completion of work

Noise follow-up required by government Decree No. 890-2010 (condition No. 15)

Must be conducted 1, 5 and 10 years after completion of work (2021, 2026 and 2030)

Objectives: • Ensure that noise levels from the infrastructure of the Turcot project have not

increased since before the project • Assess the effectiveness of mitigation measures (noise barriers)

If noise levels are too high:

• Adjustment of measures in place or implementation of new mitigation measures
