Sponsor's own description
Patients with unilateral transmission hypoacusis due to otosclerosis undergoing stapedectomy surgery will be prospectively included. They will be undergoing a free field vocal audiometry using the Oldenburg MATRIX software to evaluated the squelch effect gain between audiometry before and after 9months after surgery. Our hypothesis is to show a squelch effect with the rehabilitation of the binaural audition.
