Ojo Moses Kayode


The study investigated the effect of auditory training on sound discrimination among students with hearing impairment in Calabar Metropolis. The study was guided by two research questions and two hypotheses. Literature was reviewed according to the variables of the study. The study adopted a pretest-posttest control quasi-experimental design. Purposive sampling technique was used to select 20 students from a population of 200 students. The instruments used were Scene Analysis Scale (SAS) and Sound Keenness Scale (SKS). The instruments were given to Special Educators, and Measurement and Evaluation experts for face validation. The reliability of the instrument was ascertained using Cronbach alpha and the coefficients of the sub scales were 0.82 and 0.88, which showed that the instrument is reliable. The questionnaire was administered to the students first as a pretest and after three weeks of instruction, the post test was administered to both groups. The data was analysed using simple percentages and Analysis of Covariance (ANCOVA). The results showed that auditory training has a significant effect on sound localization and recognition among students with hearing impairment. Based on the findings, it was recommended, among others, that students with hearing impairment should be helped with auditory training and relevant therapies.
