Vintage Toronto Ads: The Best Sound System Money Can Buy

Why waste money on pricey luxury stereo systems when creating an enticing sonic environment at home? A simple investment in two concrete blocks certified by the Ontario Concrete Block Association will amplify your life. And when your house, condo, or apartment is built with high-quality concrete blocks, you will never receive a noise complaint from the neighbours when life dictates that you have to crank the volume up to eleven or commit any potential audio atrocity no one else should hear. Ask your friendly neighbourhood stonemason how they can create customized concrete blocks to house your iPod, turntable, and other system components!
We looked into the soundproofing capacities of walls made from concrete blocks in terms of sound transmission class (STC) units. According to the National Research Council, walls made from concrete blocks do an effective job of containing noise, with a basic, no-frills wall earning a rating of 45 to 55 STC (at 30 STC, a loud human voice can be heard through the wall, at 60 STC, it shouldn’t be heard).
Since this ad appeared, the Ontario Concrete Block Association has expanded its scope across the country and is now known as the Canadian Concrete Masonry Producers Association.
