Author(s): Aninda Duti Arun Banik, Rajiv Jalvi
Abstract: Introduction: There is a lack of quantitative test for Pseudohypacusis testing especially in Indian languages. Other objective tests such as ABR, ASSR & OAE are available but it is an Expensive, time-consuming and also there is a lack of infrastructure to carry out these tests. Falconer’s lip-reading test (1966) using mono-syllabic homopheneous words was used to detect pseudohypacusis. Same had to be modified and could be used for developing it into a quantitative test for pseudohypacusis. Need of the study: With the advent of growing pseudohypacusis cases especially in India due to governmental scheme benefits, it is highly necessary to develop a suitable, effective and quick Quantitative test to detect thresholds for pseudohypacusis cases reducing the time-constraints, expenses & also keeping in mind the infrastructure. Also, there is a lack of quantitative test in the world scenario. Objectives of the study: To develop a Quantitative test to detect thresholds of pseudohypacusis. Developing the same in Marathi language. Creating normative data. Also, comparing effectiveness of mono-syllablic homopheneous words v/s bi-syllablic homopheneous words in the same test. Methodology: The test was developed in Marathi and comparison was done between mono-syllablic homopheneous words v/s bi-syllablic homopheneous words at different intensity levels. Also, 20 males & 20 females were included in the study for creating normatives. Results: Appropriate statistical analysis was done where monosyllabic homopheneous words showed scores of 50.2%, 28%, 66.6% & 83.40% whereas bi-syllabic homopheneous words showed scores of 53.2%, 32%, 71.6% & 87.4% respectively at 4 different intensity level wrt SRT. Same where being analyzed amongst males v/s females. Discussions: Scores showed that there were significant differences amongst the 2 list of words and that Bi-syllabic homopheneous words yielded better results & could be a better material to detect pseudohypacusis. On gender comparison there were no significant differences. Conclusion: A better quantitative test was developed to detect thresholds of pseudohypacusis with modifications to the original Falconer’s Lip-reading test wrt intensity levels and also using Bi-syllabic Homopheneous words rather than mono-syllabic words. Thus, a simple, quick, effective and a much better Quantitative test was evolved for pseudohypacusis in an Indian language (Marathi).
