Knights Insulation Ltd.- Soundproofing

Having an issue with noisy neighbors? Need to effectively reduce airborne sound transmission? We offer sound batts and retrofit insulation options.

STC (Sound Transmission Class) - Transmission loss (TL) begins when sound waves strike one side of a partition or assembly (for example, a wall, ceiling, or floor), causing it to vibrate.

The vibration travels through the partition and produces a sound on the other side. Some of the vibration energy may be lost during the transmission, which results in TL. High TL means that less sound is produced on the other side of the partition.

The STC rating is a single number rating of how well a building partition or assembly reduces airborne sounds transmission from one space to another, thus increasing TL. In short, STC measures how much sound is held inside the room, rather than being transferred to other rooms.

The expression soundproofing while commonly used can easily be missunderstood. More correclty the sound is reduced substantially depending upon the degree of soundprooofing added. We would be glad to advice you on your options and the respected advantages.
