Abstract

Background and Aims In noisy environments, one of the skills that is critical for speech perception is spatial auditory processing. The spatial auditory processing ability of older adults decreases due to structural and physiological changes in the auditory cortex, central auditory pathways and peripheral auditory system. This study aims to compare the dynamic spatial auditory processing in Persian-speaking old and young people with normal hearing.
Methods This study was conducted on 35 older adults aged 55-70 years with normal hearing (16 men and 19 women) and 35 young people aged 18-25 years with normal hearing (15 men and 20 women). To investigate the dynamic spatial auditory processing, after performing preliminary examinations such as otoscopy, audiometry, and tympanometry, the Persian version of the speech, spatial and qualities of hearing scale (SSQ) and the spatial hearing questionnaire (SHQ) were completed through interview. Then, the dynamic spatial-quick speech in noise test (DS-QSIN) and the binaural masking level difference (BMLD) test were taken, and the values ​​of signal-to-noise ratio (SNR) loss, SNR-50 and masking level difference (MLD) were recorded for each person.
Results There was a significant difference between older adults and young people in the SSQ and SHQ scores, SNR-50, SNR loss and MLD (P<0.05). No statistically significant difference was found in these scores based on gender (P>0.05).
Conclusion Despite normal hearing, dynamic spatial auditory processing in Persian-speaking older adults has a weaker performance than in young people.
