A new way of experiencing and perceiving sound
INVISIBLE PLAYER
In the graph on the bottom left, we can observe the sensitivity of the human ear to
different frequencies when the volume is low: the highest and lowest tones are less
perceptible, while the middle frequencies are more easily heard.
To the right is the curve that inspired the frequency response of the Acoustic energy
transmitters. This innovative system acts as a ‘physiological volume compensator’,
automatically adapting the sound
to ensure balanced and natural listening at any volume level, making every acoustic
detail perfectly perceptible and improving listening comfort.
Invisible Player redefines the sound experience by transforming surfaces made
of plasterboard, wood, Plexiglas, glass, e-bond, metal and many other materials
into extraordinary acoustic speakers. Thanks to advanced technology, it creates
a flat, directive and homogenous sound wave, covering a wide frequency
spectrum (40 to 16,000 Hz depending on the material), with limited angular
dispersion. The result? A sound that remains perfectly in phase in every
corner of the room, offering a listening experience that is uniform and perfectly
tuned to the sensitivity of the human ear.
Unlike conventional audio systems, where the sound changes drastically depending
on the listener’s position, Invisible Player guarantees constant volume and
clear sound wherever you are. Whether you are close to the sound source or at
the opposite end of the room, the quality remains impeccable, eliminating those
annoying inconveniences of excessive volume or unclear sound.
Perfect for complex environments such as offices, museums, meeting rooms,
churches and shops, Invisible Player delivers smooth, intelligible sound, even
at low power, guaranteeing superior listening comfort. Its versatility also
makes it ideal for unexpected applications: it can be integrated into furniture such
as kitchens, wardrobes, armchairs, mirrors, saunas and even swimming pools,
transforming the objects themselves into sound speakers.
