How is the hotel soundproofed?

1, wall sound insulation. Sandwich wall structure design, with cement layer, sound insulation felt, sound insulation board, vibration-absorbing keel gap filled with sound-absorbing cotton and gypsum board, can well isolate air and vibration noise, and achieve the purpose of moisture-proof and sound insulation.

2, the ground sound insulation. The ground adopts floating structure design, and the ground is separated from the original floor structure by using steel mesh, sound insulation pad, concrete and other materials. Avoid floor impact sound from the original building floor to the ceiling of the lower room. The laying of damping pads should be smooth and seamless, and the number of damping pads should be designed according to vibration points and sound tolerance)

3. Sound insulation of doors and windows. The exterior of the soundproof door is wrapped with fabric, and a matching door frame is installed to ensure the sealing performance of the soundproof door. The sound insulation window adopts double-layer laminated glass, which can weaken the transmission effect of air and vibration noise at the same time.

4, pipeline sound insulation. The air conditioning and ventilation pipes in and out of the room and the sewer pipes in the bathroom will also produce noise, which can avoid the impact of running water ventilation on the environment. Wrap the outer wall of the pipeline with sound insulation felt and seal it with sealant. At the same time, the pipeline with poor stability is fixed by elastic shock absorber hanger to avoid pipeline vibration and sound.
