You might be as quiet as a mouse, but the world outside is a noisy place. There’s traffic, a passing jet engine above you, or even that annoying blare from your neighbor’s lawn mower. A lot of the most bothersome noise occurs at low frequencies—the type most difficult to isolate.
You can’t control the noise around you, but you can do a lot to prevent exterior noise from ruining the inner peace and tranquillity of your home or office. Windows and doors let in a lot of noise, often more than the walls. If your budget allows, invest in deep, high-performance windows and doors.
