We are often asked to calculate<\/a> the level of sound absorption required for an environment, only to later discover that the real issue is not the noise within the space itself, but the noise coming from outside.<\/p>\r\n

It is therefore appropriate to clarify the crucial difference between sound absorption and sound insulation.<\/strong><\/p>\r\n

Let\u2019s start from the fact that noise<\/strong>, by definition, is an unpleasant sound \u2014 it is what prevents us from concentrating at work, from clearly hearing our interlocutor, or simply causes annoyance, to the point of becoming a significant source of discomfort and stress for people.<\/p>\r\n

Noise can originate from different sources, either inside the environment in which we are or outside of it.<\/p>\r\n

There are two distinct ways to manage and control noise.<\/strong><\/p>\r\n

The first concerns the behaviour of a building with respect to sounds coming from the outside world<\/strong> (or from neighbouring dwellings); we refer to this concept as sound insulation.<\/strong><\/p>\r\n

The second concerns the acoustic characteristics of the environment in which one lives<\/strong> \u2014 how it reacts to internal sound sources. In this case, we speak of sound absorption<\/strong>.<\/p>\r\n

Let\u2019s differentiate the two phenomena and their respective solutions:<\/strong><\/h2>\r\n

\r\n

SOUND INSULATION<\/h2>\r\n

When disturbing noises from areas outside the analysed environment pass through walls and floors \u2014whether through airborne transmission (for example, when voices are heard) or structural transmission (vibrations caused by impacts such as footsteps from an upstairs neighbour) \u2014 they must be properly identified and corrected.<\/p>\r\n

Sound insulation<\/strong> consists in interposing a barrier to the transmission of sound energy from one environment to another,<\/strong> acoustically isolating a space from external sounds and vice versa.
Since sound propagates in different ways from one room to another, the actions required to counteract this transmission must also reflect this diversity.<\/p>\r\n

For effective sound insulation, the necessary measures<\/strong> must be planned during the design phase and implemented during the building\u2019s construction,<\/strong> as they act directly on the structural elements of the building – the very medium through which sound propagates.<\/p>\r\n<\/div>\r\n
