   The World Health Organization (WHO) criterion for "priority for hearing aids" in children is an average hearing loss in the 31 to 80 dB HL range in the better ear (WHO, 2004 [19]). However, if there is a local capacity to provide appropriate hearing health care, according to McPherson and Olusanya (2008), [ 4 ] then this does not preclude ...

   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]

   Hearing sensitivity varies according to the frequency of sounds. To take this into account, hearing sensitivity can be measured for a range of frequencies and plotted on an audiogram. Other method for quantifying hearing loss is a hearing test using a mobile application or hearing aid application, which includes a hearing test.
