Assessment of Speech Intelligibility in Free-field Sound Chamber at Different Signal Noise Ratios
Öz: Objective: In the presence of background noise, understanding speech is challenging for any listener, especially for those with serious hearing loss.This study aimed to determine speech intelligibility of normal-hearing adults in quiet and noisy free fields.Methods: This study included 77 volunteers with normal hearing aged between 18 and 30 years (mean: 22.25±2.7 years). Speech intelligibility scoreswere determined using the non-adaptive method at different signal-to-noise ratios (SNRs) and changing the noise direction (front and rear).Results: The mean ± standard deviation of the adaptive matrix speech reception threshold in quiet for 50% intelligibility was 22.69±3 dB soundpressure level. Speech intelligibility scores obtained at -10, -5, and 0 dB SNRs were significantly different when the noise was presented from the frontto rear direction (p<0.05). Better speech intelligibility scores were obtained when noise was presented from the rear.Conclusion: The standard audiometric test battery does not measure speech intelligibility in noisy environments. Therefore, speech intelligibility inthe noise test developed and normalized in the native language of the patient should be used in the evaluation. Because our study was conductedin free field, the results could be used in the evaluation of patients using cochlear implants and hearing aids in free field.
Anahtar Kelime: Değişik Sinyal Gürültü Oranlarında Konuşmayı Ayırt Etme Performansının Serbest Alanda Değerlendirilmesi
Öz: Amaç: Arka plan gürültüsü varlığında konuşmayı anlamak herhangi bir dinleyici için zordur. Özellikle işitme kayıplı kişiler için bu sorun daha fazla yaşanmaktadır. Bu çalışmanın amacı, işitmesi normal olan genç yetişkin bireylerde gürültede konuşmayı anlama performansının serbest alanda farklı sinyal-gürültü oranlarında bir norm değeri oluşturmaktır. Yöntemler: Çalışmaya 22 erkek ve 55 kadın olmak üzere normal işitmeye sahip 77 gönüllü katılmıştır. Gönüllülerin yaş aralığı 18-30’dur (ortalama: 22,25±2,7). Katılımcıların, non-adaptif yöntem ile farklı sinyal gürültü oranı uygulanarak ve gürültünün yönü değiştirilerek konuşma skorları tespit edilmiştir. Bulgular: Adaptive matrix konuşmayı alma eşiğinin ortalama ve standart sapma değerleri 22,69±3 dB ses basıncı seviyesi olarak bulundu. -10, -5 ve 0 dB sinyal gürültü oranında elde edilen konuşmayı ayırt etme oranları, gürültü ön ve arka yönlerden sunulduğunda, önemli ölçüde farklı bulunmuştur (p<0,05). Gürültü arkadan verildiğinde konuşma ayırt etme oranları daha yüksek bulunmuştur. Sonuç: Standart odyometrik test bataryası gürültüde konuşmayı anlama yeteneğini ölçmez. Bu nedenle, değerlendirmede hastanın ana dilinde geliştirilen ve normalize edilen bir gürültüde konuşmayı anlama testi kullanılmalıdır. Çalışmamız serbest alanda yürütüldüğünden, bu çalışmanın sonuçları serbest alanda koklear implant ve işitme cihazı kullanan hastaların değerlendirilmesinde kullanılabilir.
