چکیده

مقدمه و اهداف
امروزه سالمندی تاثیرات عملکردی محسوسی بر فرآیندهای پردازشی شنوایی مانند پردازش فضایی شنوایی می­گذارد که بارزترین جلوه آن اختلال درک گفتار در نویز می­باشد. هدف از مطالعه حاضر مقایسه توانایی پردازش شنوایی فضایی در افراد جوان و سالمند است.
مواد و روش ­ها
در مطالعه حاضر 20 بزرگسال جوان 18 تا 28 ساله با شنوایی هنجار و 20 سالمند 60 تا 70 ساله (11 مرد و 9 زن) با شنوایی هنجار و اختلال درک گفتار در نویز بر اساس معیار ورود وارد مطالعه شدند. توانایی پردازش فضایی با استفاده از نسخه فارسی پرسش­نامه شنوایی فضایی (P-SHQ) در دو گروه مقایسه گردید.
یافته ­ها
مقایسه میانگین امتیازات با استفاده از آزمون t مستقل نشان می­دهد که تفاوت معناداری بین دو گروه در میانگین امتیازات خرده­مقیاس درک گفتار در نویز-سکوت، جهت­یابی و همچنین امتیاز کلی پرسش­نامه وجود دارد. جنسیت بر نتایج مطالعه تاثیری نداشت.
نتیجه­ گیری
به نظر می‌رسد امتیازات کمتر سالمندان دارای شنوایی هنجار در پرسش­نامه شنوایی فضایی نسبت به جوانان، به معنای عملکرد ضعیف آنها در پردازش فضای شنوایی است. نتایج مطالعه حاضر از تأثیر سن بر پردازش­های فضایی شنوایی مانند جهت­یابی و درک گفتار در نویز حمایت می­کند.

چکیده [English]

Background and Aims: Aging has apparent functional effects on auditory processing, such as spatial hearing processing, with the most apparent being speech in noise perception disorder. The aim of the present study was comparison of spatial hearing ability between young adults and elderly people.
Materials & Methods: According to the inclusion criteria, 30 young adults with the age range of 18 to 28 years old with normal hearing and 20 elderly people with the age range of 60 to 70 years old with normal hearing and speech in noise disorder were included in study
Results: The comparison of mean scores using independent t-test showed that there was a significant difference in the mean scores of speech in noise-quite, lateralization, and total score between the two groups. Sex had no effect on the results obtained,
Conclusion: Lower scores of elderly people with normal hearing in spatial hearing questionnaire, compared with young adults, can be defined as their weak performance in spatial hearing processing. The results of the present study reconfirms the effect of age on spatial hearing processing, such as lateralization and speech in noise.
