Abstract

The study aimed to investigate the working memory and speech recognition in noise from individuals with Sensori Neural Hearing Loss (SNHL) with and without auditory neuropathy spectrum disorder (ANSD). The purpose of assessing working memory recommends for a potential intervention program to perceive speech. Twenty participants in the age range of 16–44 years, diagnosed as having mild to moderate SNHL were recruited for the study. The participants were divided into two groups based on the presence and absence of ANSD (10 in each group). The visual working memory was assessed in all the participants using the Operation Span Test, Reading Span Test and Visual Backward Test. Speech perception ability was assessed using the SNR 50 test. There was no significant difference between the scores of Operation Span, Reading Span, and Visual Backward Span for individuals with SNHL with and without ANSD. There was a significant difference between the scores of SNR 50 f or individuals with SNHL with and without ANSD. The visual working memory in individuals with and without ANSD is similar. Speech perception in noise is significantly affected in ANSD than SNHL without ANSD. Thus, it is recommended to use speech reading, which utilizes visual working memory to interpret the message, as previous studies have reported that individuals with ANSD show limited benefit in auditory mode of rehabilitation alone.
