Losing Your Audition without Even Knowing It

Here are some recent findings about about ‘the hidden lost audition ’

Traffic Noise

” Conventional wisdom says that damage to our hearing is an age-related phenomenon. But researchers caution that in a noisier world, chances are that more people, at younger ages, will begin to exhibit signs of hearing loss, hidden or otherwise. ”


You can have this hidden audition loss by being exposed to sounds that we don’t necessarily consider traumatic,” . The sound levels on a city street aren’t thought of as traumatic, but they can be enough.

Baie d’Urfé plans for a sound wall in 2021

Highway 20 east in Baie d’Urfé – (The Montreal Gazette)

Mayor Tutino said ” “Over the years we have put money aside to pay this out of our surplus “


You see a health issue, you act to correct it and protect your citizens. No small politics to put people against each other in order to keep control. No mumbling about extended delays and being dependant on the MTQ.


The mayors of Baie d’Urfé, Laval and Longueuil signed up for a sound wall in the last year!

“The city of Pointe-Claire had listed, as recently as late 2015, a proposed sound wall to run between St-Jean Blvd. and Sources Blvd. in its capital program for infrastructure projects. ” (The Gazette, January 22 2020)


Baie d’Urfé gets a sound wall. What about Beaconsfield?

Baie d’Urfé gets a sound wall paid 50% by the MTQ and 50% by the city’s surplus. For the mayor of Baie d’Urfé this is a health decision to protect her citizens.


In Beaconsfield, the proposal is 75% for the MTQ and 25% for the city. But the mayor is talking about difficulties, costs overruns and delays. To him this is a decision about money.


In June 2019, the mayor of Beaconsfield has announced a surplus of 10 Millions $ from the welcome tax over the last 5 years. So the city has the money,

10 Millions in surplus over 5 years !

The mayor wants to quash this project with a loan referendum where he will ask “Do you want to pay for a sound wall ?” to those who will NOT benefit from that noise protection…

But the mayor of Baie d’Urfé can use the city’s surplus without asking for a referendum?

About 23% of the Beaconsfield population is sick because of the noise and air pollution near the Highway 20. That is 4,500 citizens, including 2,500 kids, most of them located less than 20 meters from the highway in their homes, in a primary school, in a daycare, in a high school and an academy.

The citizens of Beaconsfield waited for 35 years to resolve this HEALTH ISSUE.


So it seems the mayor of Beaconsfield wants to save the money and get re-elected without considering the health of those citizens and those kids who are suffering in this polluted area.

We say that this is a Public Health issue, and therefore the highest priority project for our city.

PS Thank you GLOBAL NEWS for covering this story.



November 12 and 13, 2019: the Ministry of Health organized the first edition of this two-day event, in collaboration with several other ministries, including transport and environment. It was a great success! Two hundred and forty five (245) participants were registered.

The event was intended for the municipal sector, representatives of citizen groups and non-profit organizations, academia, health and social services network and community stakeholders as well as the various government departments and agencies concerned by this issue.

We have heard lectures on several important dimensions of this scourge and we have mainly made contact with several important players in this field in Quebec in ministries, research centers, cities and dedicated organizations.

This conference will have impacts.

Measure the noise impact at your home

Noise measurement tool to “see” the impact

Some say they are not affected by the noise level stemming from the highway. They believe in what they see, and since the harm is invisible, they say noise does not bother them. They forget that the impact is real and cumulative over years (both for noise and air pollution). Here is a simple way to “see” the noise level.

Take your smart phone or your tablet and go where you can download apps. Search for a “Decibel meter” app. You will be presented with many apps : Some are free, such as Soundprint, Decibel X, Sonometre, Decibel Meter. Other apps come at a fee.

Find the one you feel at ease with and go outside of your house on a weekday around 8 AM or 6 PM. Go on the side where the highway is. Start the app and watch the results. Look at the needles moving when a train is added in the environment..

Please note :

  • This mesurement is instantaneous. The measurement refered to by the Environment specialists and by the Government is an average measure over twenty four (24) hours. So, that includes the relatively low levels of the night.
  • An app on a phone cannot be as precise as the scientific equipment used by the authors of the studies.

Following is the general evaluation grid used by the MTQ (1987 and 2010) when measuring the noise levels along the Highway 20 :

This is the grid used to evaluate the noise levels : Below 55 dBA is weak, 60 dBA to 65 dBA is average, and beyond 65 dBA is strong and requires mitigation.

Impact of air pollution on children when their school is along a highway

September 17 2019 : CBC aired video, audio and web articles about the air and noise pollution in schools along the highways. Here are excerpts and links :

“One hundred and twenty seven (127) primary and secondary schools in Greater Montreal are within a hundred and fifty metres of busy roads, a zone that health authorities in Quebec and elsewhere have deemed hazardous to sensitive people.”

Ultra-fine particles concentrated near roads

” The area immediately next to busy roads has been found to have high concentrations of ultra-fine particles (UFPs). Pollutants too small to be filtered by the nose and trachea often make it inside the lungs. “

“From school administrators to senior staff, these issues have not been raised by any of these schools,” EMSB spokesperson Michael J. Cohen wrote in an email.

Marguerite-Bourgeoys School Board, which has six of its hundred and thirteen primary and secondary schools near busy roads, including Beaconsfied Primary, responded similarly. 

There is little distance between the schoolyard at Léonard-de-Vinci school in Montreal and the busiest highway in Quebec, Highway 40. (Sudha Krishnan/CBC)
