The Department of Veterans Affairs John L. McClellan Veterans Affairs Medical Center Audiology section has a need for an Interacoustic Brand Name GSI Corti Diagnostic Distorsion Product Otoaccoustic Emissions/Transient Evoked Otoaccoustic Emissions (DPOAE/TEOAE) system that allows audiologists and medical staff to evaluate both screening and diagnosis of DPOAE and TEOAEs. The ability to have the capability for screenings and diagnostics is required as part of the initial acoustics evaluation of hearing balance and related disorders in order to identify early any sensitivity to normal sounds and prevent hearing loss.
