Abstract
Auditory Middle Latency Response (AMLR) provides assessment of peripheral and central auditory system integrity, as well as auditory pathways up to the thalamo-cortical region and primary auditory cortex level.
Aim: In Ömer Halisdemir University Training and Research Hospital Audiology clinic, it was aimed to obtain AMLR normative data in healthy individuals to be a reference in evaluating the results of patients in the future.
Method: 10 female and 10 male individuals, aged 20-50 years, with normal hearing and no neurological or otological complaints were included in the study. AMLR test with 500 Hz tone burst stimulus at 70 dBnHL was applied to all individuals.
Results: Mean wave latencies; 21.85 ms for the Na wave; 30.25 ms for the Pa wave; For the Nb wave, it was obtained as 38.97 ms.
Conclusion: Normative data of our clinic were created for the Na, Pa and Nb latency parameters of AMLR.

Abstract
İşitsel orta latans cevapları (Auditory Middle Latency Response-AMLR), periferik ve merkezi işitsel sistem bütünlüğünün yanı sıra talamo-kortikal bölge ve birincil işitsel korteks seviyesine kadar olan işitsel yolların değerlendirilmesini sağlar.
Amaç: Ömer Halisdemir Üniversitesi Eğitim ve Araştırma Hastanesi Odyoloji Kliniğinde, gelecekte hastaların sonuçlarını değerlendirmede referans oluşturmak üzere, sağlıklı bireylerde AMLR normatif verileri elde etmek amaçlanmıştır.
Yöntem: Çalışmaya 20-50 yaşları arasında, normal işitmeye sahip, nörolojik ve otolojik yakınması olmayan 10 kadın ve 10 erkek birey dahil edildi. Tüm bireylere 70 dBnHL’de 500 Hz tone burst uyaranla AMLR testi uygulandı.
Bulgular: Ortalama dalga latansları; Na dalgası için 21,85 ms; Pa dalgası için 30,25 ms; Nb dalgası için ise 38,97 ms olarak elde edildi.
Sonuç: AMLR’nin Na, Pa ve Nb latans parametreleri için kliniğimize ait normatif veri oluşturuldu.
