Newborn hearing screening uses objective testing methods (usually otoacoustic emission (OAE) testing or automated auditory brainstem response (ABR) testing) to screen the hearing of all newborns in a particular target region, regardless of the presence or absence of risk factors. Even among developed countries, until the 1990s, it could take ...
From 1993 to 1996, NCHAM directed a National Consortium for Newborn Hearing Screening that resulted in over 100 hospitals in 10 states implementing newborn hearing screening programs. [ 9 ] [ 10 ] [ 11 ] From 1996 to 2000, NCHAM staff worked with newborn hearing screening programs in 35 states and provided direct assistance to over 200 ...
Marion Downs (January 26, 1914 – November 13, 2014) [1] was an American audiologist and professor emerita at the University of Colorado Health Sciences Center in Denver. She pioneered universal newborn hearing screening in the early 1960s and spent over 30 years advocating for its adoption in hospitals, as well as for the provision of hearing aids to infants displaying hearing loss.

Newborn hearing testing is done at the bedside using transiently evoked otoacoustic emissions, automated auditory brainstem responses, or a combination of both techniques. Hearing screening programs have found the initial testing to cost between $10.20 and $23.37 per baby, depending on the technology used. [33]
A pure tone audiometry hearing test is the gold standard for evaluation of hearing loss or disability. [medical citation needed] Other types of hearing tests also generate graphs or tables of results that may be loosely called 'audiograms', but the term is universally used to refer to the result of a pure tone audiometry hearing test.
This prevents the non-test ear from detecting the test signal presented to the test ear. The threshold of the test ear is measured at the same time as presenting the masking noise to the non-test ear. Thus, thresholds obtained when masking has been applied, provide an accurate representation of the true hearing threshold level of the test ear. [13]
