The hotel decorated a design to decide indoor acoustical environment greatly, especially of large space public more such. In adornment design lieutenant general creates artistic environment and physical environment union to rise, be united in wedlock and unite of art and function namely, will give a kind of new distinguishing feature and advantage for hotel creation. For this, this print invites academia of our country sound famous expert Hu Jun civilian the gentleman writes this paper. The hotel lingers as passenger pass through the territory of a country, accommodation and recreational place, must have beautiful and quiet living environment. Gorgeous but extremely noisy hotel, affect a passenger to rest not only, also will reduce hotel grade and class greatly, accordingly, to hotel illuminative acoustical environment should grant to take seriously adequately.
One, environmental noise level is right hotel kind the acoustical environment of the building, GBJ118-1988 " design of civil building sound insulation is normative " specific stipulated the standard is restricted to be worth, detailed sees next tables:
2, the noise origin inside guest room of environment of guest room sound has:
(1) is passed outside the urban noise that the window outside the wall passes person guest room;
(2) is passed inside the comes from photograph adjacent guest room noise that partition sends a person;
(The clash that 3) transmits by floor;
(4) passes corridor noise hum of the person through guest room door;
(5) toilet, conduit passes the noise inside adjacent guest room of the person;
(6) ventilated system passes fan noise of the person. Come from the noise interference of different position to prevent these, must have relevant control measure to these place:
1, window. The sound insulation ability of the window is inferior, and need often open, want to be in the overall planning proceed with of area from control city noise and hotel above all to outside noise, the hotel should be far from busy traffic artery as far as possible. When the influence when outside noise allows the requirement of noise level inside contented guest room hard, should with a view to rises outside the sound insulation ability of wall window. Taller to sound insulation requirement hotel, should use double deck glazing, design good double deck glazing, noise insulation factor can have 25-30 decibel. The sound insulation ability of the window removes vitreous ply factor outside, of the window sealed more important, its influence is 4 ～ about 10 decibel. In addition, the distance between double window, have inside the frame of the window all affect its to lie between sound energy force without sound absorption material. If choose the vitreous combination of different ply, will conduce to abate low frequency resonance and in high frequency coincidence effect.
2, the partition between guest room. The sound that the television inside guest room, radio gives out and loudly the life noise such as the talk, it affects the quiet rate of photograph adjacent room directly. The removed wall with undesirable sound insulation is more such, passenger constant because of photograph adjacent room talk loudly or TV broadcasts and the influence ponders over a problem, rest and Morpheus. Accordingly, how the noise insulation factor that sound economy ground decides the partition between guest room is the problem that must solve above all. Normally, the noise insulation factor of the partition between guest room is the allows noise level difference inside the sound level of life a confusion of voices inside guest room and guest room the value adds 4-5 decibel again. Normally the noise insulation factor of the partition between hotel guest room should be more than 50 decibel, the guest room with a bit low level, should be 40-50 decibel. The noise insulation factor that the brick mixes the brick wall in the building is in 50 decibel above; Half brick wall is 47 decibel; 140, the ferroconcrete wall with 180 large millimeter is 47-48 decibel; Aerocrete block wall is hollow the noise insulation factor with 75 large millimeter is 50-51 decibel. 3, the sound insulation of floor. Basically be isolation clash, if footstep, furniture procrastinates,use voice. The clash class of floor should be controlled it is under 60 decibel. Show some commonly used floor, its bump sound level to be in about 70-75 decibel, the hollow floor of 95 millimeter, its bump sound level to achieve 85 decibel, short of is less than the requirement of 60 decibel.
