& acoustic comfort
Today our “living” is not limited to the home: our daily life is made up of spaces in which we live for more or less time, such as the office, the school or the places where we go during our free time.
For these environments we are always looking for the maximum acoustic comfort: a matter of well-being and health, because if the areas frequented daily are not acoustically adequate, we suffer the consequences as a real physical disturbance.
Our isolspace mission is to obtain the perfect acoustic comfort in every environment for the well-being of every space with the added value of being able to create an acoustic comfort that is beautiful to hear but also to see, thanks to the endless range of possible customization of our products.
LAW & STANDARDS
The Italian legislation is not- thorough concerning the acoustics of interior spaces There are indeed no limits or dispositions that define the- reverberation time of a room. The only exception concerns school-, particularly classrooms and gyms. In this regard, the Prime Ministerial Decree 5/12/1997 “Determination of passive acoustic requirements of buildings” refers to the Circular of the Ministry of Public Works No. 3150 of 22 May 1967, which indicates as average reverberation time values, measured at the frequencies 250- -500-1000-2000 Hz, the limit of 1.2 sec for classrooms (a furnished classroom with the presence of two people at the most) and 2.2 sec for gyms.
A further evolution is represented by DM of 11 October 2017 which refers to CAM criteria (minimum environmental criteria). These criteria concern the acoustic comfort of public environments by stating that “indoor spaces must be suitable for the achievement of the values specified for the noise indicators pursuant to UNI 11532″.
The UNI 11532 “Acoustics in building – acoustic characteristics of internal confined environments” proposes reference values of reverberation time that are considered suitable for living environments.
In 2018, it was issued the Part 1 that describes the reference parameters, the techniques to design, determine and assess the acoustic quality of an environment. Currently, at UNI the parts of the standard relating to individual sectors, starting from the school, are under development and they will be issued within the end of 2019.
