Perfect performances every time
Careful acoustic design and tough materials help audiences enjoy great sound quality at this outdoor venue
Located on the site of a demolished paper mill at the confluence of Saint-Laurence and Saint-Maurice rivers, the Cogeco Amphitheatre has become a signature building for the Trois-Rivières area. This imposing structure features a 25 metrehigh roof and includes seating for 3,500 people and space for a further 5,500 on a sloped lawn.
As for any open-air performance venue, close attention to acoustics is essential to ensure that sound carries properly without causing echoes or getting lost in the air. So acoustic consultants Octave chose a blend of materials to ensure that sound was absorbed and reflected in the right places. The roof’s underside is built with perforated custom steel panels on top of 50mm of ROCKBOARD® 80 acoustic stone wool insulation, with lower-density AFB® insulation used toward the back of the stage.
ROCKWOOL stone wool’s properties are ideal for this venue, where temperatures can range from -30°C to 30°C and humidity stays high because of the nearby rivers. Stone wool resists moisture, absorbs unwanted noises and echoes easily and helps keeps interior spaces at comfortable temperatures. Stone wool retains these properties whatever the weather, ensuring that performances are always of a consistent quality. And as a non-combustible material it contributes to fire safety at the amphitheatre too. Audiences in Quebec now have a sophisticated outdoor performance venue that can play host to the largest local, national and international productions.
