What is Soundproof

Let's first clarify the difference between sound insulation and acoustic treatment. Very often people are not aware of these concepts, and they confuse sound insulation with room acoustics. Sound insulation aims to separate the internal acoustic environment from the external one.

Sound insulation is necessary for the tranquility of the two separate sides - external and internal. It is wonderful when there is silence and tranquility in our home, but when we want to celebrate some significant event or just watch a movie on the home surround system, it is desirable to follow the rule if we want peace and quiet and we need to keep the peace and quiet. In every day life this is hard to acieve and this is where sound insulation becomes a major factor.

When sound or vibration is created, whether it is outside the walls of your home or inside it, energy is generated. When it reaches the boundaries of your home (walls, floor, ceiling), some of that energy becomes heat, another part goes through the wall and continues to spread, and a third part reflects and returns to the same space in which it was created. The purpose of sound insulation is to reduce the amount of sound energy passed through the walls, floor and ceiling. One of the best ways, according to Audio Design, and perhaps the only correct way to soundproof, is the technique room-in-room. Other techniques put partial insulation on the floor, walls or ceiling which is less effective and can be apply if necessary. However the nature of sound is the vibration of the air molecules, so where there is an air there is a sound. That's why pay attention at doors, window seals, power supply ducts, ventilation systems usually this sound paths are neglected. As mentioned above, in addition to the sound that propagates through the air, we also have vibrations that propagate into the solids materials. That's why for an efficient room-in-room technique, the tight connections between sound-proofing materials and structures should be avoided.

What we can do is to install a layer of high-density mineral wool on the floor, next on the top of it we can install reinforced mask and finally tiles, parquet or other flooring. Of course, there should be no rigid connections along the walls, and for this purpose Audio Design uses a special vibration membrane that slides along the walls. The walls use a plasterboard sandwich and a special high density acoustic membrane, behind which a mineral wool with a density of 80 to 120 kg/m3 is tightly applied. Insulation of doors and adjacent doors is the most difficult. Usually, a well-fitting and sealing tape is used, a door as tight as possible, but the real way is to use double doors. Windows are actually the biggest problem, and it is almost impossible to completely insulate windows. The lack of such is strongly recommended for places where good acoustics are important - recording studios, for example.We review the insulation on the floor and walls in our "room-in-room", which remained a ceiling for which we could use an acoustic suspended ceiling. Underneath it can be insulated for impact noise as it is on the floor, so that the rooms above and below will be maximum insulated. Care should be taken with the suspended ceiling, which additionally plays the role of partial insulation of the room, and if overcoated with the insulation or suspended ceiling, it may fade. Audio Design experts measure the characteristics of the room with professional equipment and then offer a suitable sound insulation solution with high quality insulation materials.
