| 2 | Enhanced auditory evoked potentials in musicians:A review of recent findings显示文摘Auditory evoked potentials serve as an objective mode for assessment to check the functioning of the auditory system and neuroplasticity.Literature has reported enhanced electrophysiological responses in musicians, which shows neuroplasticity in musicians. Various databases including Pub Med, Google, Google Scholar and Medline were searched for references related to auditory evoked potentials in musicians from 1994 till date. Different auditory evoked potentials in musicians have been summarized in the present article. The findings of various studies may support as evidences for music-induced neuroplasticity which can be used for the treatment of various clinical disorders. The search results showed enhanced auditory evoked potentials in musicians compared to non-musicians from brainstem to cortical levels. Also, the present review showed enhanced attentive and pre-attentive skills in musicians compared to non-musicians. | Himanshu Kumar Sanju Prawin Kumar | 2016 | Journal of Otology2016，11，2： | 0 |
| 3 | Pre-attentive auditory discrimination skill in Indian classical vocal musicians and non-musicians显示文摘Objective:To test for pre-attentive auditory discrimination skills in Indian classical vocal musicians and non-musicians.Design:Mismatch negativity(MMN) was recorded to test for pre-attentive auditory discrimination skills with a pair of stimuli of /1000 Hz/ and/1100 Hz/,with /1000 Hz/ as the frequent stimulus and /1100 Hz/ as the infrequent stimulus.Onset,offset and peak latencies were the considered latency parameters,whereas peak amplitude and area under the curve were considered for amplitude analysis.Study sample:Exactly 50 participants,out of which the experimental group had 25 adult Indian classical vocal musicians and 25 age-matched non-musicians served as the control group,were included in the study.Experimental group participants had a minimum professional music experience in Indian classic vocal music of 10 years.However,control group participants did not have any formal training in music.Results:Descriptive statistics showed better waveform morphology in the experimental group as compared to the control.MANOVA showed significantly better onset latency,peak amplitude and area under the curve in the experimental group but no significant difference in the offset and peak latencies between the two groups.Conclusion:The present study probably points towards the enhancement of pre-attentive auditory discrimination skills in Indian classical vocal musicians compared to non-musicians.It indicates that Indian classical musical training enhances pre-attentive auditory discrimination skills in musicians,leading to higher peak amplitude and a greater area under the curve compared to non-musicians. | Himanshu Kumar Sanju Prawin Kumar | 2016 | Journal of Otology2016，11，3： | 0 |
| 4 | Word perception in noise at different channels in simulated cochlear implant listeners显示文摘AIM:To find out effect of different signal-to-noise ratios(SNRs) on word perception at different number of channels.METHODS: Thirty participants with normal hearing in the age range of 18-25 years(mean age 23.6 years) were involved in the study. For word perception test, there were 28 key-words embedded in sentences comprises of four lists processed for different channels(4, 8 and 32 channel) using AngelS im program at-5, 0 and +5 SNRs. The recorded stimuli were routed through audiometer connected with computer with CD player and presented in free field condition with speakers kept at 0° azimuth in a sound treated room.RESULTS: Repeated measure ANOVA showed significant main effect across different SNRs at 4 channel, 8 channel and at 32 channel. Further, Bonferroni multiple pairwise comparisons shows significant differences between all the possible combinations(4, 8 and 32 channel) at +5 dB SNR, 0 dB SNR and-5 dB SNR.CONCLUSION: Present study highlights the importance of more number of channels and higher signal to noise ratio for better perception of words in noise in simulated cochlear implantees. | Prawin Kumar Himanshu Kumar Sanju Sudhir Kumar Varun Singh | 2016 | World Journal of Otorhinolaryngology2016，6，2： | 0 |
