Sound Product Testing

No one wants to be bothered inside their home or office with unnecessary sound, so windows can be tested to see how well they are at keeping sound outside where it belongs.

Sound testing is calculated based on a large spectrum of sound waves that are blasted at a window and the amount that gets to the interior of the building is expressed in two different values.

  • STC (Sound Transmission Class) is a measure of the spectrum of sound of typical conversations between people.
  • OITC (Outdoor-Indoor Transmission Class) is a measure of the spectrum of sound that is typically more disruptive, such as trains, planes, cars and trains.
