Over the past six years, we have held many discussions and meetings about increased airplane noise over Belmont and Watertown.
MassPort has been very responsive in trying to help us understand and address the concern. As part of that response, they installed a noise monitor at a home in Belmont in March. The Belmont Noise Monitoring Report presents the results of those measurements, together with an analysis of which noise events correlate with plane overflights (according to radar).
Belmont noise levels should generally be slightly higher the Watertown noise levels, since planes are climbing and getting further from the ground as they go from Belmont to Watertown. The report finds that the noise levels are roughly 20 decibels below the thresholds that we could get the FAA to take action on. 20 decibels is a very big gap.
We are trying to get underneath the numbers and understand whether particular events might be have having a greater impact. We want to understand whether the use of averaging prevents noise problems from appearing in the statistics. More to come on this.
I’ve been working with Belmont and Watertown representatives to Massport’s Citizen Advisory Counsil, Dennis Duff and Myron Kassaraba, and with State Representatives Hecht and Rogers on the issue and we hope to bring back a full accounting for the situation and the options we have explored for a remedy in the fall.
