Comprehensive Wide Bandwidth Test Battery of Auditory Function in Veterans (CWTBAFV)
The accurate assessment of auditory status is critical for planning treatment for Veterans with hearing loss to include medical and audiological management. Current physiologic tests of auditory function in the standard clinical audiological test battery for Veterans have limited sensitivity in detecting some middle-ear disorders, and do not include a direct test of cochlear function. Recent studies have shown promise for new wide-bandwidth (WB) tests of absorbance for improved sensitivity in the assessment of middle-ear function including acoustic reflex testing. The addition of WB tests of cochlear function included in the WB test battery provides an opportunity to improve audiological diagnosis of a range of hearing disorders in Veterans. The automation provided by the WB test battery could provide additional benefits in reducing the duration of the evaluation, leaving more time for evaluation of test findings and counseling. Results from this study may lead to the improvement of audiological care for Veterans with hearing loss.

- Middle ear test [ Time Frame: Assessed at time of enrollment ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]An otoacoustic emission test assessed using a transient wideband stimulus from 1000 to 8000 Hz.
