While both the reports cite “Bamford” to highlight the requirement of a hearing aid in an infant, report ‘a’ says that this age can be as early as four weeks, and the report ‘b’ puts this age as a median age of four months (Bamford et el, 2005 and 2006). However, the report ‘b’ has given the further information that the identification of infants with the permanent hearing loss disability can start from as early as ten weeks, which has been found after the introduction of ‘newborn hearing screening program” (NHSP) during the year 2001.
As this is the most important part of the study, proper importance has been given to this issue in the report ‘b’, which has analyzed the “Permanent Childhood Hearing Impairment, (PCHI). The definition given for the same in this report is technically sound as it has defined it in the terms of ‘better ear hearing standards of 500Hz to 4K Hz, with more than 40dB-HL.levels. This report has cited (Fortnum et al 2001) saying that it includes the sensorineural and permanent hear losses. However, citing (Davis at el 2004), the report says that PCHI excludes the temporary and unilateral hearing loss and the causes of the PCHI are not known, although it can be congenital or acquired.
While report ‘a’ points to the electrophysiological methods that include ABR and ASSR to determine the exact condition of the pediatric audiology, report ‘b’ is more elaborative as it has given details in “appendix-1”, towards the introduction of care pathways for screening the hearing of infants, within its first few weeks after the birth. This report further informs that under “NHS-NHSP” program an audiologist can monitor such screening and decide on the fitting of the hearing aid to the infant. Report ‘a’ has cited (Hall—2006) saying that ASSRs has a unique place in determining the required time and age as the same has a guaranteed place in the ‘pediatric test .battery’. .
