Sonova hearing-aid frequency-response curve study

Completed Sonova AG clinical investigation of hearing-aid frequency-response-curve variations and fitting/software configurations in adults with bilateral sensorineural hearing loss; this is a study-level record rather than a distinct marketed product program.

Verified as a real Sonova AG-sponsored completed ClinicalTrials.gov study, not a standalone commercial product record. The study compared standard and modified hearing-aid frequency-response curves/fitting programs in adults with bilateral sensorineural hearing loss. ClinicalTrials.gov lists actual enrollment of 25, completion on 2023-10-11, posted results on 2025-03-18, and no FDA-regulated drug/device flag. The generated intervention arms should remain collapsed into this single software/neurotech study-level record.
