Today, our ‘living space’ is no longer limited to the home: our daily life consists of spaces where we spend varying amounts of time, be it the office or, more generally, the environment in which we work, school, public places and locations we frequent in our free time.
We are increasingly seeking the utmost acoustic comfort for these environments. This is essential for our well-being and health because if the spaces we use on a daily basis are not adequately soundproofed, this can have very disruptive consequences.
Isolspace’s mission is to provide every room with optimal acoustic comfort in order to ensure the well-being of the people who use it, while providing an added benefit: the ability to create infinite combinations of shapes, colors and finishes, offering acoustic comfort that is not only pleasing to the ear, but also to the eye.
Current Italian legislation is not entirely comprehensive when it comes to indoor acoustics: there are no limits or guidelines specifying the appropriate reverberation time within various living spaces. The only exception is school buildings, particularly classrooms and gyms. In this regard, Prime Ministerial Decree 5/12/1997 “Determination of Passive Acoustic Requirements of Buildings” refers to the Ministry of Public Works Circular No. 3150 of May 22, 1967, which specifies as average values for reverberation time, measured at frequencies 250-500-1000-2000 Hz, a limit of 1.2 sec for classrooms (furnished classroom with no more than two people present) and 2.2 sec for gyms.
The Ministerial Decree of October 11, 2017 is a further development that refers to CAM (Minimum Environmental Criteria), which in turn, with respect to the acoustic comfort of public spaces, states that “Indoor spaces must be suitable for achieving the values indicated for acoustic descriptors set out in UNI 11532”.
UNI 11532 “Indoor Acoustic Characteristics of Confined Spaces” proposes benchmark values of optimal reverberation time for living spaces.
In 2018, Part 1 was published, which describes the benchmarks and predictive design and inspection techniques for assessing the acoustic quality of spaces. The parts of the standard relating to individual sectors, starting with the school sector, are being finalized at UNI level for publication by the end of 2019.
