• Noise Monitoring

    At Toronto Pearson, we are committed to the continuous improvement of our Noise Management Program. We monitor noise in the areas surrounding the airport to gather objective data and assess noise levels in the community.

    To help the public better understand airport noise and Noise Monitoring Terminals, we asked Acoustician Colin Novak to answer a few questions for us. Watch the videos below to learn more about measuring aircraft noise.

     

     

    Noise Monitoring Terminal Review

    As our airport continues to grow to meet passenger and economic demand in the region, we understand the importance of reviewing and updating our noise program.

    A review of the Noise Monitoring Terminal (NMT) locations in our surrounding communities was identified as one of the 2015 initiatives of GTAA’s Five Year Noise Management Action Plan, developed with Toronto Pearson’s Community Environment & Noise Advisory Committee (CENAC).

    Why do we need a review of our NMTs?

    It’s important that Toronto Pearson is effectively measuring the current noise environment in the communities impacted by the airport to help us to understand the impacts of our operations. Traffic levels and operations have changed since the last NMT Review; therefore we are reviewing the NMT locations to ensure we are accurately measuring airport noise impacts.

     

    OVERVIEW

    Step 1 – Establish Working Group

    In the summer of 2015, an NMT working group was established. It included five CENAC members, an Acoustician and GTAA staff members.

    Step 2 – NMT Site Criteria Review

    The working group reviewed the NMT site criteria.

    Step 3 – Analysis of Existing and Potential NMT Site Locations

    The working group examined where the existing NMTs were located in relation to flight operations and clusters of complaints.

    .

    The group agreed that noise from departing traffic and arrivals on final approach were captured using the existing NMTs.

    The group identified ten areas for temporary noise monitoring to capture two phases of arrival flight traffic not captured by current NMTs:

    1. Arrivals nearing the final approach phase of flight.
    2. Arrivals in the downwind phase of flight, near the start of the base turn.

     

    These areas were characterized as having:

    1. Concentrated traffic
    2. Low altitudes for that phase of flight
    3. Complaint clusters

     

    Step 4 – Temporary Noise Monitoring

    Noise data was collected at the 10 locations in Summer/Fall 2015.

    Step 5 – Recommendation to CENAC

    The working group assessed: noise monitoring results, annual traffic levels and complainant numbers.

    Based on the assessment, the committee recommended that eight sites be considered for permanent NMTs.

    The results and recommendations were presented at a public CENAC meeting on June 22, 2016. You can view the presentation here.

    Step 6 – Implement any recommendations



    Currently in progress.

    All eight sites were approved for the installation of a permanent NMT.

    The next steps include:

    1. Precise site selection;
    2. Lease agreements for site;
    3. Installation of equipment and integration with Toronto Pearson’s Airport Noise & Operations System (ANOMS) and WebTrak.
