Symphonia allows to simulate a realistic sound environment and makes the patient feel the benefits provided by advanced hearing aid features, without having to leave the room. Symphonia’s advanced algorithm reproduces background noises recorded with special multichannel microphones, to make the patient feel inside a realistic external environment. In order to make Symphonia work, you only need a specific multichannel USB soundcard connected to the PC and a set of loudspeakers. SOUND FIELD SOUNDS Symphonia provides background noises recorded with special multichannel microphones, and reproducing them with an advanced algorithm makes the patient actually feel inside a realistic external environment. DIRECTIONAL SOURCES Voices or musical instruments can be added to the sound field and moved all around the patient, to simulate directional sounds coming from different directions (up to 3 different sound sources). It is also possible to add custom sound files to the library and use them as additional sources. SPEAKERS The loudspeakers configuration is flexible: it consists of 3 to 8 active or passive loudspeakers (an additional multichannel amplifier is required in the latter case) placed freely from 1 to 2 meters around the place where the patient sits. CALIBRATION Symphonia allows you to control sounds emission with real dB SPL values (from 50 to 85): for this reason, a calibration procedure is available. Also, any asymmetrical disposition of loudspeakers is automatically compensated.
