Federal, provincial and municipal governments all have standards for levels of acceptable sound, but they can be next to impossible to enforce, without pin-pointing a specific source.
Outside airborne sounds reach the ear on the inside of a dwelling by entering through roofs, doors, cracks, windows, floors and walls. Impact sound, on the other hand, results from foot traffic, dropped or sliding objects and travels through construction materials, primarily floors and ceilings. The “sound insulation” of a wall is that property which enables it to resist the passage of noise or sound from one side to the other. According to MasonryWorx President Jack Prazeres: “The rule of thumb in wall sound insulation is simply the denser the product the better the sound insulation.” In contrast, “sound absorption” is that property of a material that permits sound waves to be absorbed into a wall, reducing noise levels by eliminating echoes or reverberations.
