Conclusion: The results suggest that high frequency audiometry should be used together with standard audiometry in the detection and follow-up of individuals who are at potential risks for hearing losses.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objectives: Changes in hearing thresholds were determined by standard and high-frequency audiometry in subjects exposed to occupational noise for long durations, Patients and Methods: Hearing thresholds were measured between 250 and 16000 Hz frequencies by standard and high frequency audiometry in 64 male workers (mean age 42 years; range 31 to 55 years) of a hydroelectric power plant and in 30 age- and sex-matched controls with no hearing problems.
📊
Key Findings & Data:Results: The mean hearing thresholds of workers showed significant increases in all frequencies from 4000 to 16000 Hz (p<0.005), the most affected frequencies being 4000, 6000, 14000 and 16000 Hz (p<0.0005). increases in hearing thresholds were significantly correlated with the noise level and duration of exposure to noise (p<0.05).

Abstract

Objectives: Changes in hearing thresholds were determined by standard and high-frequency audiometry in subjects exposed to occupational noise for long durations, Patients and Methods: Hearing thresholds were measured between 250 and 16000 Hz frequencies by standard and high frequency audiometry in 64 male workers (mean age 42 years; range 31 to 55 years) of a hydroelectric power plant and in 30 age- and sex-matched controls with no hearing problems. The workers were divided into three groups according to the noise level and into four groups according to the duration of exposure. Results: The mean hearing thresholds of workers showed significant increases in all frequencies from 4000 to 16000 Hz (p<0.005), the most affected frequencies being 4000, 6000, 14000 and 16000 Hz (p<0.0005). increases in hearing thresholds were significantly correlated with the noise level and duration of exposure to noise (p<0.05). Conclusion: The results suggest that high frequency audiometry should be used together with standard audiometry in the detection and follow-up of individuals who are at potential risks for hearing losses.

Özet

Amaç: Bu çalışma uzun süre gürültüye maruz kalanlarda standart ve yüksek frekans odyometri ile işitme eşiklerindeki değişiklikleri saptamak amacıyla yapıldı. Hastalar ve Yöntemler: Hidroelektirik santralinin farklı gürültüye sahip çeşitli birimlerinde çalışan 64 erkek işçide (ort. yaş 42; dağılım 31-55) ve işitme problemi olmayan 30 erkek gönüllüde (ort. yaş 42; dağılım 31-55) safses odyometri ile 250-16000 Hz arasında işitme eşikleri ölçüldü. İşçilerden, maruz kalınan gürültü düzeyine göre üç, gürültüye maruz kalma sürelerine göre dört grup oluşturuldu. Bulgular: İşçilerin ortalama işitme eşiklerinin 4000-16000 Hz arasındaki tüm frekanslarda yükselmiş olduğu görüldü (p<0.005). En fazla etkilenen frekanslar ise 4000, 6000, 14000 ve 16000 Hz idi (p<0.0005). Gürültü düzeyi ve gürültüye maruz kalma süresi arttıkça işitme eşiklerinin daha fazla etkilendiği izlendi (p<0.05). Sonuç: İşitme kaybı riski altındaki bireylerin belirlenmesi ve takibinde standart odyometri ile birlikte yüksek frekans odyometrisinin de kullanılması gerektiği sonucuna varıldı.
