New
born hearing screening has enabled the professionals to successfully detect a
hearing loss at earliest. Successful hearing screening protocol involves a
battery of tests, which should have high sensitivity and reduced false positive and negative responses. Moreover, protocol should be cost effective and less
time consuming. Such protocol calls immediate implementation in screening
program to detect hearing loss and certainly benefit beneficiaries to enroll in
habilitation and or rehabilitation.
To investigate sensitivity and
specificity of individual and combined physiological hearing tests utilized in
newborn hearing screening program. A total of 572 ears (286 infants)were screened using high frequency tympanometry, acoustic reflex measure and
transient evoked oto-acoustic emission (TEOAE). Despite all screening tests
were passed auditory brainstem response (ABR) was measured at 30 dBnHL for
confirmation of normal hearing.
