Lateral Inhibition Therapy (TIL) corrects the patient's hearing by notched amplification on the patient's listening soundtrack. This half-octave notch is targeted at tinnitus frequencies measured tonal. The device slightly increases the amplification around the notch, so that the cerebral cortex compensates for this "gap" in the sound spectrum, masking the crippling tinnitus at the same time. This research is based on a new algorithm developed by the SIEMENS Company which proposes an attenuation of tonal tinnitus by a TIL by notched amplification emitted by the hearing device, object of the study.

In France, up to 16 million people suffer from tinnitus or ringing in the ears daily. This parasitic sound that does not come from the patient's environment can interfere with each individual in a variable way, sometimes creating an insurmountable handicap which has not known any effective treatment validated to date.
