Experimental: Magnetic Contact Hearing Aid
Subjects were treated with a hearing aid which provided amplification intended to treat mild to moderate sensorineural hearing loss. Acute performance and safety assessed at 4 months compared to unaided baseline pre-treatment, followed by longer-term assessment of safety up to 10 months.
Device: Hearing Aid
Subjects were treated with a hearing aid which provided amplification intended to treat mild to moderate sensorineural hearing loss.
- Maximum Effective Sound Pressure Level (MEPO) [ Time Frame: 1 month ]A primary outcome measure of interest is an estimate of the insitu maximum equivalent pressure output (MEPO) of the EarLens system, which represents the sound pressure level that would have to be applied at the eardrum (or tympanic membrane) to produce the same degree of tympanic membrane (TM) vibration that the EarLens system produces with the coil current set to its maximum value, and given the anatomical constraints on the coupling between the coil and magnet for a given subject. The target fitting range included hearing loss up to 60 decibels (dB) Hearing Level (HL). In order for the device to be an effective hearing aid for this target population, the maximum output of the device needs to be able to provide output and gain to treat this maximum hearing loss.
