Damping type sound insulation
material
Damping noise felt is an excellent sound insulation material, it
can sound insulation, but also absorb vibration. Whether used
alone or in combination with other materials have very strong
sound effects, more valuable is that it is of various sound
frequencies are basically "equal", even the most difficult to
deal with low frequency can effectively solve.
The damping soundproof blanket can be divided into different
thickness, the thicker the better, the general method of using
the soundproof blanket is sandwiched between two layers of rigid
materials (such as gypsum board, gypsum board) can help to
reduce vibration and noise in. We run experiments, as shown by
the blue line is not sound felt a sound insulation wall sound
insulation effect, the red curve is clamped the soundproof felt
after the sound effect.
Sound insulation felt very heavy, the weight of a roll of sound
insulation felt in 40 kg of the general 2mm thick at 10 meters,
3mm thickness of 5 meters
