Psychoacoustics is considered to be a category of psychophysics and is termed as the assessment of auditory or sound perception and deals with perception of sound among different human beings. Psychoacoustics is a very qualitative phenomenon and is often the reason for an individual to perceive the sound in different manner, as compared to another. This effect is more prominent in music wherein a given music bit may seem good to one, whereas, another may perceive it as bad. For this to happen, various attributes of sound play an important part, in the categorization based on psychoacoustical perception. The present work considered pitch as the varying attribute and provided a comparative assessment of sound, based on the variation of pitch in terms of Pitch Detection Threshold (PDTh) between trained musicians and non-musicians. 44 subjects of both conditioned and controlled set were considered for this study and were made to undergo the Pitch Detection Test (PDT) to assess their PDTh. Two trials were conducted, once in the morning and the other in the evening. The results provided substantial cue to conclude that the musicians had a better PDTh (6.83 dB) than the control set (31.31 dB). Also, the PDTh was better in the morning trials, as compared to their evening counterparts. This could be attributed to the professional training in music, due to which the conditioned set outperformed the control set of subjects. Such an analysis could aid in the assessment of auditory perceptive abilities and their improvement with music and hence indicate the plausible improvement in the auditory perception with music based raaga therapy. Further, more attributes such as intensity and frequency could be encompassed to provide stronger relationship between perception and learning, in this case being music training sessions, which could also work as therapy for certain auditory perceptive disorders. |
