The quality of modern restaurant services is measured through a number of different sensations: from the warmth of the welcome and the tastefulness of the décor, through to acoustic and thermal well-being. La Mercanti sound-deadening panel systems provide a single solution for meeting all these requirements, with maximum design versatility, ease of installation and durability. That’s why they are being used more and more in prestigious and elegant environments, which choose La Mercanti products and services.

Environmental health and quality are today indispensable elements that characterise good architectural design in both the public and private sectors. We are all aware of the risks deriving from overexposure to noise in the working environment.

ARCHITECTURAL ACOUSTICS
The parameters defining the acoustic quality of a confined space are all interrelated and their values determine the degree of acoustic quality of a theatre or concert hall, as well as MEETING ROOMS, OFFICES, SCHOOLS, RESTAURANTS, shops, test rooms, theatre and so on.
The reverberation time is one of the most well-known parameters in the acoustics field and it expresses the environmental “resonance”.
Another descriptor of some importance for conference rooms, places of worship, schools and offices, is represented by the Speech Transmission Index, which describes the intelligibility of the spoken word.

SOUND ABSORPTION AND SOUND INSULATION
These are two completely different concept. A wall in brick is heavy and highly sound insulation, but it is not sound absorbing. The heavier the wall, the more it insulates against external noise. Similarly, we can say that a fibreglass panel is light and highly sound absorbent, but it’s not sound insulating.

SOUND ABSORBING PANELS
A sound absorbing mechanism is obtained using perforated wooden, plaster or metal panels. The panel behaves as a large sound “trap” which can offer high sound absorption values.
Our panel is a sound absorbing panel manufactured in milled MDF with internal resonators that make use of the acoustic properties of the previously mentioned sound absorbing systems, thus combining optimum acoustic performance with agreeable aesthetics.

This panel uses three sound absorbing systems: perforated sound absorbing panels, sound absorbing resonators and vibrating panels or membranes.
The soundproofing lining systems lends itself to installation with any type of wall and false ceiling improving the acoustics inside closed rooms, where it eliminates echoes and absorbs excess noise.
