Sound Insulation Determination of Door

Article Preview

Abstract:

The structural complexity of a door causes difficulties in the description of its behavior from an acoustical point of view. In many cases, even a small change can cause a big difference in its sound-isolating properties. To determine the acoustical quality of a door, it is important to perform laboratory measurements of the door structure and door frame, the gaps including. A mathematical analysis based on experimental measurements of the sound reduction index of several door constructions was used to determine the acoustical door categories. The equations for calculating the sound reduction index, which were introduced in this paper, should help in the design of a suitable door from an acoustical point of view.
