People who live near the MUHC superhospital have become used to hearing constructions noises over the past few years.
But at some point this summer residents who live north of the Glen Yards have been hearing an incessant humming.
"It causes sleepless nights, irritability, a general feeling of malaise," said Henry Mietkiewicz.
He and his wife thought they were the only ones being subjected to the noise, but after receiving multiple complaints the city of Westmount organized a meeting with the MUHC and the contractors working on the building.
"It helps the MUHC to realize that it is not just one or two residents who is upset with this. This appears to be a problem that is much larger than just on one street," said Mayor Peter Trent.
Officials from the superhospital explained that the noise began in April, when contractors began testing ventilation and cooling systems. .
When the hospital began operating the systems at full capacity in October, the sound got worse.
"It's extremely frustrating because it's like having a bus parked outside your window 24/7," said Mark Felgar.
The hospital will assign a task force to identify the exact cause of the sound and attempt to minimize it.
Until then, officials will work on a temporary solution by reducing the amount of air flowing through the ventilation.
"We're going to be very simply lowering the volume of the evacuators by 50 percent hoping the residents will feel it right away," said Denis Crevier, the president of GISM.
The contractors and the MUHC will meet with Westmount officials in December to see if any progress has been made.
