Types of Doors and its Impact on Airborne Sound Insulation

Abstract

Acoustically speaking, a door as a part of a wall cladding or internal wall partition is usually the weakest element of such a structure [1,2]. The less effective sound insulation properties of a door, in comparison with the main wall structure, results in the fact that the sound reduction index of the door is one of the most important factors affecting the total sound isolation properties of a complex wall.
