Introduction Previous literature has reported ill-effect of ototoxic drug on hearing and balance. Present study investigated awareness among medical doctors for the same. Method A total of 55-medical doctors of multiple specialties from Assam, India participated in the present study. A total of 14 questions with Likert Scale based scoring pattern were framed and validated for the present study. Results Outcome of the present study showed high awareness percentage about side effect ototoxic drugs was obtained, which was a satisfying outcome.

Introduction Acoustic change complex (ACC) is a type of event-related potential evoked in response to subtle change(s) in the continuing stimuli. In the presence of a growing number of investigations on ACC, there is a need to review the various methodologies, findings, clinical utilities, and conclusions of different studies by authors who have studied ACC. Objective The present review article is focused on the literature related to the utility of ACC as a tool to assess the auditory discrimination skill in different populations. Data Synthesis Various database providers, such as Medline, Pubmed, Google, and Google Scholar, were searched for any ACC-related reference. A total of 102 research papers were initially obtained using descriptors such as acoustic change complex, clinical utility of ACC, ACC in children, ACC in cochlear implant users, and ACC in hearing loss. The titles, authors, and year of publication were examined, and the duplicates were eliminated. A total of 31 research papers were found on ACC and were incorporated in the present review. The findings of these 31 articles were reviewed and have been reported in the present article. Conclusion The present review showed the utility of ACC as an objective tool to support various subjective tests in audiology.

Earlier investigations have reported congenital hearing loss in pre-term infants. Present study investigated hearing tests among pre-term infants to know the percentage of pre-term infants with hearing impairment. Two stage hearing assessment of pre-term infants showed congenital profound hearing loss in 16% of the infants. Present study showed the importance of TEOAE and ABR as efficient tool for hearing screening of high risk infants.
