Objective Classification of Auditory Brainstem Responses to Consonant-Vowel Syllables Using Local Discriminant Bases

ConclusionThis study shows the efficiency of frequency and time-frequency domains features. The results indicate that time-frequency features obtained by local discriminant bases were more successful in objective classifications of the responses. Besides, the selected features from the phase of the frequency responses were reliable in classifying the responses to consonant-vowels /da/, /ba/ and /ga/.SignificanceThe importance of this study lies in the fact that it helps the objective classification of auditory brainstem responses underlying the different encoding of three consonant-vowels (/ba/, /da/ and /ga/) in frequency and time-frequency domains.
