Normal hearing adults
Adults between 20 and 79 years old with hearing at all audiometric frequencies between 250 and 8000 Hz at less than or equal to 25 dB HL
Adults with sensory neural hearing loss
Adults between 20 and 79 years old with sensory neural hearing at one or more audiometric frequencies between 250 and 8000 Hz.
Adults with middle ear disorders
Adults between 20 and 89 years old with middle ear disorders: tympanic membrane perforation, serous otitis media, cholesteatoma, otosclerosis, and unspecified middle ear disorders.
- Middle ear test [ Time Frame: Assessed at time of enrollment ]The standard clinical middle ear test, 226 Hz tympanometry, and the experimental wideband middle ear tests of absorbance and admittance.
- Middle ear muscle reflex test [ Time Frame: Assessed at time of enrollment ]The standard clinical middle ear muscle reflex test assessed with 226 Hz admittance changes, and the experimental wideband middle ear muscle reflex test assessed with wideband admittance and absorbance changes.
- Wideband otoacoustic emission test [ Time Frame: Assessed at time of enrollment ]An otoacoustic emission test assessed using a transient wideband stimulus from 1000 to 8000 Hz.
