Noise insulation in the apartment is a very sore question. Due to the architectural features of obsolete or simply cheaply built buildings, the sound sometimes spreads to several floors. As a rule, sound insulation is made in a certain direction-1-2 walls, floor or ceiling. At the same time, the doors of interior colors often sound and their texture from sound insulation is very suffering. As a rule, there are recommended finishing materials for soundproofing.
Often some pair of cracks is enough to let the sound inside. Therefore, the question is approached thoroughly. First, the frame is mounted in order not to miss anything, sound insulation is laid inside it-both the budget option 30-40 dB of absorption (cotton) and expensive, providing mogic silence of soundproofing materials. Plasterboard panels are fixed on top, at the joints they should be lubricated with sound -absorbing material, they are fixed if possible with dowels in sound -absorbing covers.
How much such sound insulation will give? From 60 to 80 dB of sound absorption. Given that a person does not hear sounds in the region of 20 dB, even very loud music will not hurt to fall asleep sweetly.
