Abstract

Objectives: To evaluate afferent hearing system of musicians with pure sound audiometry, high frequency audiometry, transient-evoked otoacoustic emission and to examine the efferent hearing system with medial olivocochlear complex suppression. Materials and Methods: A total of 60 people, including 30 orchestra artists and 30 control groups, were included in this study. Hearing thresholds were evaluated with Pure Tone Audiometry. TEOAE test was first measured, then contralateral acoustic stimulation (CAS) with 70 dB narrow band noise was given and measured simultaneously with TEOAE test. The average rehearsal time is 4 hours per day and varies between 20-35 hours per week. Results: A significant threshold increase in the left ear was detected at orchestral staff at 16 kHz (orchestra group 42.17 dB; control group 31.83 dB). TEOAE amplitudes were significantly lower at all frequencies in orchestra (p

Özet

Amaç: Orkestra sanatçılarında afferent işitme sistemini saf ses odyometri, yüksek frekans odyometri, geçiciuyarılmış otoakustik emisyon ile; efferent işitme sistemini ise medial olivokoklear kompleks supresyon testi ileincelemektir. Gereç ve Yöntem: Aynı orkestrada çalan en az 5 yıl deneyimi olan 30 sanatçı ve kontrol grubuolarak müzik icra etmeyen 30 gönüllü alınmıştır. Saf Ses Odyometri (SSO) ve yüksek frekans odyometri ileişitme eşikleri değerlendirilmiştir. Transient uyarılmış otoakustik emisyon (TEOAE) testiyle ilk olarakkontralateral akustik stimülasyon (KAS) verilmeden önce ölçümler alınmış, daha sonra 70 dB dar band gürültüile KAS verilerek aynı anda TEOAE testiyle medial olivokoklear kompleks refleksi (MOCR) ölçülmüştür.Ortalama prova süreleri günlük 4 saat; ortam gürültüsüne maruz kalma süreleri haftada 20-35 saat arasındadeğişmektedir. Bulgular: SSO eşiklerine göre; orkestra çalışanlarında 16 kHz’de özellikle sol kulakta anlamlıbir eşik yükselmesi tespit edilmiştir (orkestra grubu 42,17 dB; kontrol grubu 31,83 dB). TEOAE amplitüdleri,orkestra sanatçılarında tüm frekanslarda anlamlı derecede azdır (p
