What are the causes of poor sound insulation in hotels and how to deal with them?

In the complaints of hotel guests, the problem of sound insulation accounts for almost 75% of the bad reviews. Hotels provide accommodation services for their guests, and the demand for accommodation is often inseparable from these two points: quietness and comfort. Once the sound insulation is not done well, it will directly affect the rest of the guests, that is to say, a hotel can not provide quiet and comfortable accommodation services for guests. On the one hand, the complaint is that the basic service is not done well, and the loss of guests affects the hotel rating and directly affects the hotel occupancy rate. When the hotel is decorated, it is necessary to pay attention to the sound insulation of the rooms. If the decoration is not done well, no matter how to remedy it later, the effect is not great.

Sound insulation of walls

1. Selection of concrete aerated block brick for wall

Concrete aerated block brick is a kind of concrete brick with porous structure. When the sound wave is incident, the air in the cave will violently rub against the wall of the brick wall, thus greatly losing the sound energy and reducing the noise. Just like a professional recording studio, a layer of sound-absorbing cotton is usually attached, which is the same principle. At the same time, a large number of pores and micropores can also play a role in heat preservation. Don't use cement for building walls, because the joints between cement-connected bricks can't be completely dense. Generally, 200 mm thick aerated block brick, after plastering on both sides, the wall thickness is about 230 mm thick, which can achieve better sound insulation effect.

2. The wall sound insulation must reach the top.

Because the ceiling can't play the role of sound insulation, if the sound insulation of the wall of the guest room is not up to the top, the sound of other rooms and corridors will be transmitted to the room through the top, so the sound insulation effect of the whole wall will be greatly reduced, so the sound insulation of the wall must reach the top, otherwise the money will be spent, but the sound insulation will not be done well, which is not worth the loss.

3. Fill the reserved holes of fire pipes and water pipes.

Don't fill it with cement mortar. Many hotels like to use surplus cement mortar when filling the reserved holes of fire pipes and water pipes. In fact, cement mortar can't fill tiny holes, so it's better to fill them with styrofoam.

Sound insulation of doors

When hotels do sound insulation, there is a place that is easily overlooked, the door. The sound insulation of the door is not concentrated on the door, but on the crack of the door and the bottom of the door.

1. The thickness of the hotel door is preferably about 5 cm, and the inner core of the door filled with log mechanical board is selected.

Generally speaking, the thicker the door panel, the higher the density and the heavier the weight. The thicker the door panel and the higher the flatness, the better the sound insulation effect of solid wood. However, considering the bearing and wear of door frames and hinges, it is generally about 5 cm. The wood of log mechanical board has sound insulation characteristics, and oblique cutting holes are formed in the processing of three-dimensional log mechanical board. Due to the straight-line propagation of sound, the sound insulation coefficient increases exponentially with the increase of the thickness of the board, and the sound insulation decibel of the 4cm log mechanical board after pressing the panel can reach 32 decibels. But also more environmentally friendly than the traditional bridge hole mechanical board.

2. Double-row sealing strip technology is adopted for door edges and gaps.

Compared with the single sealing strip, the double sealing strip is more tightly sealed, which can effectively block the sound of the corridor and has a certain heat insulation effect.

3. Install the automatic sealing strip at the bottom of the door.

Because there is generally a gap of 3~5 mm at the bottom during construction, this gap is the place with the largest sound transmission. When the door is closed, the automatic sealing strip will fall on the threshold stone, so that the sound of the corridor can not reach the guest room, and the annoying small card can not be inserted. The sealing strip can not only reduce noise and heat preservation, but also have a certain damping effect on doors and windows, which can reduce loss. If you are in a hot climate, be sure to seal the doors and windows to prevent mosquitoes from entering the guest room.

Sound insulation of socket

In addition to the door, there is another place where almost 80% hotel owners didn't pay attention when doing sound insulation, and that is the socket. Generally, there is a bottom box under the socket panel, and the depth is about 8- 10 cm. Some workers will punch holes directly in order to save time and effort, so that they can punch two rooms at a time, but this has formed a hidden danger that affects sound insulation. Workers must be required not to punch holes correctly during construction, and the sockets in two rooms must be installed in the wrong position. Later, the problem of socket positioning can be solved by some hard bags and other designs.

Of the three places that should be paid attention to in hotel sound insulation, one place was ignored by 80% bosses.
