Wave V detection using instantaneous energy of auditory brainstem response signal

Abstract

Problem statement: ABR machine is a well known machine that has been used on detection of hearing problem especially for babies or children. In ABR, wave V is the most prominent and robust wave that has been used as indicator of hearing loss. However, a fast detection of the wave V is necessary in order to implement newborn hearing screening. There are various types of signal processing methods introduced by researchers in order to achieve the target. Fast Fourier Transform (FFT) and wavelet transform are well known techniques that have been used in digital signal processing. Approach: In this study, the instantaneous energy of ABR signal had been introduced as a marker to identify the ABR waves. Results: Study showed that the instantaneous energy of auditory brainstem response can be used a marker to identify the ABR waves. Conclusion: This study had proposed a platform for fast hearing screening system. © 2009 Science Publications.
