how to make a quiet hotel and what are the interventions to be made in the structure, interior rooms, corridors, common areas? The so-called "passive acoustic minimum requirements" or the noise that passes through walls and that disturbs sleep or concentration in daily life.
course, this also applies to hotels, under a law dating back to 1997. The DPCM
of 5/12/1997, which entered into force in February 1998, lays down minimum requirements for each "hotel, boarding and similar activities." These minimum requirements
passive acoustic down the front of the hotel has to protect from external noise, the noise must protect the base from the floor above or below, and from the foot traffic is over. How much noise can make the discharges or sanitary treatment plant or air lift.
As the evening social will be heard in the rooms etc etc
In short, the DPCM raises a number of limitations that need to be addressed by a specialist in the design phase, called "Proficient in Technical Acoustics" as defined by Law No. 447 / 1995, Article 2. Having to comply with a
a hotel facade sound insulation of 40 dB, to be considered each side of each compartment. So if you read "windows guaranteed by law" at the bottom can be a misleading advertising ....
Same for the floor slabs, which will guarantee a minimum of 50 dB sound insulation, the walls or interunità, even with their limit of 50 dB. Again one can not generalize the product or service any building.
Different speech for sound insulation, which can not go beyond 63 dB, for which the carpet is the best choice on the one hand, because in other respects can not be installed everywhere. In this case, you are supporting the sheathing subflooring, to be placed under the floor to make it float, to predict at design time.
During almost 13 years, this decree has undergone a series of explanations and will soon have a new edition. 1 The clarification states that also applies to restructuring (former regional laws as well as new decree approved in September).
requirements of sound insulation between rooms also should be respected as well as neighboring the noise level from foot traffic.
Under the new decree (according to UNI 11367 of 22/07/2010), each unit of real estate (including hotels) to be sold or have the fitness for use by the City (if new) will have a noise classification (from 1 ° to 3 °) following a hearing test performed on the work done.
Finally, in relation to its environment: Any new construction must have estimates of the analysis of the noise climate, or an analysis of the noise existing in the area where you'll want to make the neo-structure and evolution of this potential over time ....
