Noise is a widespread problem of particular interest in community environments, such as condominiums, residential complexes, hotels, resorts, holiday cottages.

It is mostly caused by the growing demands of thermo-hygrometric control of building envelopes that are increasingly stagnant. This is a very important problem that is often neglected during the design phase.
The D.P.C.M. del 5.12.97, " Passive acoustic building requirements", provides for heating systems not to exceed 35 dB in residential areas (A) for intermittent services (lifts, bathrooms, plumbing drains, faucets, toilets) and 25 dB (A) for services at continuous operation (heating, air conditioning, ventilation).
If you are a customer of a hotel as you may have been able to find out personally, not always the location of the hotel is indicative of silence or noise; you can find a hotel located above a pub and still enjoy almost total silence, or sleep in rooms in the middle of the woods and perceive constant noises, often coming from within the same facilities (thermal  power  stations and climate control, laundries, air conditioning, kitchens,  rooms small isolated from each other ...).

The nightmare of every traveler is to sleep in a noisy room due to: 

✔ Partitions between neighbouring  premises for example rooms/bathrooms  not properly insulated. Walls must provide a good level of airborne sound insulation by preventing noise from passing from a boundary partition to adjacent space.
✔ Vibrational noise of trampling and dragging furniture toward the underlying premises on the floors/ceilings. 
✔ Noise caused by heating (thermal power stations) and climate control.

If you run a Hotel you can ask for advice from 2B Resine engineers who will measure the noise level within your facility after a design description and according to current regulations.
With our soundproofing, your customers will be able to sleep peacefully! Our company operates in the field of environmental acoustics and aims to identify the  most suitable products for each project and proposes  aesthetical  solutions post  operam The most important plant categories from the point of view of the acoustic emissions on which 2B Resine works are as follows:

THERMAL POWER PLANTS:

Usually heat production occurs by means of heat generators usually installed in a closed place called thermal power plant . Cold production also takes place by  means of machines, parts of which are installed  inside, and some  outside. 2B Resine addresses the possible technical solutions to be applied ranging from machine noise reduction to vibration and sound insulation along the propagation path. 2B Resine pays attention to their positioning , to the location and eventual soundproofing of the air vents, to any noise emissions from chimneys, to vibration and solid sound transmission through the bases on which boilers, chillers, pumps , etc. rest. The noisy components of thermal power plants are: boilers, pumps, pipes.
2B Resine first examines the environment in which the machines are installed, which is the technology center (sound propagation under confinement, acoustic absorption and reverberation time, cumulative effects from different machines installed in the same place, etc.);
Secondly, it studies the transmission of noise to the outside, through masonry and doors (sound insulation) or through the necessary openings (ventilation grilles, external air intake and expulsion , chimneys, etc.);
Finally, it studies the free sound field transmission from the technology center, intended as a source of noise, to the potential receptors (presence of reflecting surfaces, acoustic barriers, etc.).
2B Resine acts on vertical and horizontal wall structures to ensure high noise absorption in the local source, associated with low transmission to surrounding environments that are subject to potential disturbance.
