Invisible Sound Masking
Why
Hearing the voices of other people, in indoor environments, can be distracting or even annoying.
In other conditions, it may be politically or financially illegal to allow the content of the speech to be heard by others.
In these years many tech solutions have been launched on the market, mostly made with conventional loudspeakers.
Oyster, on the other hand, offers an innovative solution which brings economic savings and greater efficiency.
This key bring value in open plan offices, examination rooms, banks and many other environments where privacy is important; furthermore, it also reduces the distraction caused by outside traffic, office machinery and other undesired sounds.
Some fields of usage
The technology
The concept of “sound masking” proposed by Oyster can be explained by the analogy of the diffusion of sound in the environment with the diffusion of light.
Let’s imagine a dark room in which we light a candle and then immediately put it out:
the light produced by the candle is easily identifiable.
This happens when conventional speakers are used to distribute
the sound for sound masking.
Now let’s imagine that we turn on the lights in the room where the candle is lit.
Its glow will not be as noticeable as before because it has been “masked” by the lights on in the room, which are evenly diffused, such as the sound produced by the AudioPanel Oyster.
Since the sound reproduced by the Oyster AudioPanels is “uniformly diffused”, the quality of the sound is absolute and fully satisfies the requirements suggested by the experts for the realization of systems meant for Sound Masking.
Comparison between Invisible Sound Masking™
and traditional loudspeakers
Sound Masking made with conventional speakers
Example 1.
This example shows one of the typical scheme installation in which the loudspeakers are placed in the false ceiling. In order to have a great diffusion of pink noise (Pink Noise) or white noise (White Noise), some grilles are mounted to allow the rear radiation of the loudspeakers (reflected signal) and the return into the room, among other things in counter phase and therefore part of the audio spectrum is strongly compromised. Even the healthiness of the environment is affected because, in addition to the sound, dust and micro particles present in the holes also pass through the grilles as well as a waste of energy consumed to heat or cool the air which is dispersed in the cavity.

Example 2.
In this example the speakers are placed inside the false ceiling and emit the sound into it. In order to distribute the sound in the room, pink noise (Pink Noise) or white noise (White Noise) grids are installed to allow the radiation into the room from the loudspeakers (reflected signal).
In this case also, it is necessary to use a significant quantity of loudspeakers, perhaps of small dimensions so the cost is more acceptable for a homogeneous distribution of the sound.
Even the healthiness of the environment is affected because in addition to the sound, dust and microparticles present in the cavities also pass through the grilles as well as a waste of energy used to heat or cool the air which is dispersed in the cavity.
Sound Masking made with AudioPanel CP.
From the graphic we created, it is clear how the use of Invisible Sound Masking™ completely solves the problem, both technical and architectural.
The rear radiation, being in phase with the front one, is used to add acoustic level (+ 6dB) without intervening on the amplifier.
There is no need for grilles to introduce the sound into the environment which, due to the nature of the AudioPanel, is uniformly distributed, without “hot spots” in practice areas where the sound is more present.
You find yourself pleasantly immersed in a pleasant pink noise (Pink Noise) or white noise (White Noise) which fulfills its function of ensuring more privacy, without being acoustically invasive as the audio level can be kept lower.
Furthermore, the healthiness of the environment is ensured and both if using the AudioPanel ISM-CP series (for false ceilings in mineral fiber) and the ISM-Sign series (for mounting inside walls or ceilings), the design of the environment is totally respected.

Sound Masking achieved with AudioPanel SIGN installed in the ceiling.
In a typical listening environment, speaker placement is very critical.
Sound reflections with surfaces adjacent to the source cause performance degradation
as some frequencies are removed by reflections while others are emphasized.
The destructive interaction with the walls strongly degrades the sound quality.
Invisible Sound Masking™ & Sound Diffusion achieved
with a single AudioPanel SIGN installed for example, in the ceiling.
In this example the Invisible Sound Masking Panel expresses the top of versatility.
Not only is the amount of speakers needed to cover a certain volume of space is less, but also from the same single AudioPanel it is possible to broadcast the sound for sound masking, background music, messages or any alarms from IoT devices.
Why to choose Invisible Sound Masking™ Oyster
UNIFORM SOUND DIFFUSION
Invisible Sound Masking™ distributes sound evenly within the room and over a much larger area than traditional speakers. The absence of “hot and cold” spots results in a higher quality sound masking experience than any existing approach.
EASY TO INSTALL
Invisible Sound Masking™ is based on the AudioPanel Oyster loudspeakers, an affirmed technology made up of a few essential and performing components.
A smart and light product.
SUPER EFFICIENT
Invisible Sound Masking™ offers a much wider coverage area than all other technologies and also requires less energy to be powered. Infact, AudioPanel technology has a better performance than traditional loudspeakers and the amount of energy required to power them is reduced; finally, the amount of loudspeakers needed is less.
DOUBLE ACTIVE FACE™
Invisible Sound Masking™ does not require positioned speakers as in traditional systems. The AudioPanel generates a double sound radiation, front and rear, therefore requiring fewer speakers, producing a superior quality sound masking experience as well as cost savings.
