General speaking, listening room noise is mainly external noise, outside interference noise mainly includes the city noise, traffic and vocals), the noise of the buildings in other room, such as noise, and air conditioning systems. In order to reduce the noise, listening room should choose in a quiet environment, but also as far as possible to reduce the interference between each room.

There are two approaches of incoming indoor noise. Is a kind of incident wave sound transmission through wall house, then through the noise of the air medium to this chamber, and through the crack of the door, window gap, such as air holes of the incoming air conditioning pipeline; The other is a vibration noise, it is with this room building on other buildings that have a solid connection, shock and vibration, and along the solid cohesion of spread to the interior noise.

Sound insulation must be targeted measure, the sound transmission way to stop the isolated engineering is often referred to as the "noise", to "vibration" stop isolated from engineering, and is often referred to as the "isolation" project, people often referred to as noise.

Usually adopt the heavier sound insulation materials (density), the thicker the better, design for double doors, double wall effects are good match, often use detailed sound insulation measures have the following kinds:

1. The wall: wall shall be made in the structure of the thick and heavy, in order to progress to isolate air sound. If conditional word, can be installed double wall. Set up in the medial wall sound-absorbing board, and the wall has a certain interval, nature is also a double wall properties.

2. The ceiling and carpet: if listening room located in the central part of high-rise buildings, upstairs and downstair noise can be introduced into listening room through the ceiling and floor. In order to reduce the through these channels to indoor acoustic vibration, can set the condole top, to isolate the noise coming from the sky, can be laid floor, to cut off the noise coming from the air.

3. Door and window, a pipe: can paste in the crack of the door, everywhere, sealing strip, the sound insulation disposal is one of the most simple way.

4. Doors and Windows, set up sound insulation door window is the key to the noise reduction. Door of the transmission loss depends on its weight, hardness and density. Sound insulation quantity of ordinary wooden door for 18 db, increase the weight of the door, thickness, sound insulation quantity can progress. If set up double door, sound-absorbing materials, filled with middle can obviously progress sound absorption effect.
