Abstract

Objectives: To study temporal auditory processing abilities in SNHL children using behavioural [Auditory fusion test (AFT); Duration pattern test (DPT); Pitch pattern sequence test (PPST); time compressed sentence test (TCST)] and electrophysiological measure [Mismatch negativity (MMN)]. And to study whether there is a correlation, if any, between results of behavioural tests and MMN in assessment of temporal auditory processing. Methods: This study included 2 groups: A study group of 60 children with mild to moderate sensorineural hearing loss (SNHL); and a control group of 30 normal hearing children. The children's age ranged from 6-12 years. Results: The SNHL subgroups showed statistically significant lower scores in AFT, TCST, DPT and PPST as well as longer MMN latency than their controls. Age had significant effect on temporal auditory processing tests results and on MMN parameters but gender and aetiology of SNHL had no effect. There was no statistically significant correlation between results of behavioural tests and MMN in normal as well as SNHL children. Conclusion: Sensorineural hearing loss affects temporal auditory processing abilities reflected on both behavioural & electrophysiological test results. Age showed maturational effect on behavioural tests in all subjects, but this effect was not reflected on the MMN results of the controls, despite of the significant effect of SNHL on MMN parameters. There was no correlation between behavioural & electrophysiological test results.
