[4] This physiology of congenital hearing loss due to hypoxia has put the emphasis on both treating and preventing congenital hearing loss. [...]the need for early diagnosis and screening helps to limit the disability, mostly in mild to moderate hearing impairment, as it is amenable to treatment and prevent future deteriorating manifestation of severe impairment. [...]this research study was planned to investigate any kind of hearing impairment in the preterm babies by comparing wave V latency and interpeak I-V latency. Electrode Placement o As per the International Federation of Clinical Neurophysiology (IFCN) o The monoaural montage, that is, Cz-Ml/M2 was used o Cz (forehead at the hairline) = Reference electrode o Fpz/Fz (nasion) = Ground electrode o M1/M2 (mastoid) = Active or recording electrode o Technical specifications used for the procedure- o Channels - single-channel BAEP o Sensitivity - 0.2 jiV/div o High cut filter - 3000 Hz o Low cut filter - 100 Hz o Sweep speed - 1 ms div o Input impedance - 37 weeks) [Table 1], Statistical Analysis All values were expressed as mean ± standard deviation.
