Abstract (2. Language): 
The speech tests have been used as a part of pure tone audiometry for many years. In this study, words with determined frequency properties depending on the degree of hearing loss, and the relationship with pure tone hearing thresholds was determined. The aim was to establish the relationship between speech and pure tone hearing thresholds and to have the value of frequency which is important for speech discrimination. The speech test was employed in normal hearing and hearing impaired subjects, and frequency analyses were performed in consonant-vowel-consonant words from phonemic balanced word list (PB- 300). Four lists were then obtained containing the frequency characteristics of 80 selected words. With this material, a total of 98 subjects and 152 ears were evaluated using the speech material in normal hearing and sensorineural hearing loss. The results of this study indicate that high frequency words are important for speech discrimination.

Abstract (Original Language): 
Odyolojik testlerde ve işitme cihazı uygulamalarında klinik anlamda kullanılan en önemli testler konuşma testleridir. Çalışmada amacımız konuşmayı ayırt etmede önemli olan frekans değerlerini belirlemektir. Araştırmada, odyolojik değerlendirmeler için kullanılan Fonetik Dengeli (FD- 300) kelime listelerinde yer alan sessiz-sesli-sessiz (Sz-Sl-Sz) formundaki kelimeler spektrografik olarak incelenmiş ve frekans özellikleri belirlenerek yeniden listelenmiştir. 15-56 yaş aralığında otoskopik bulguları normal 152 kulak değerlendirilmiştir. Araştırma kontrol ve çalışma grubu olmak üzere iki grup üzerinde çalışma yapılmıştır. Konuşmayı Anlama Eşiği ile 500-2000 Hz saf ses ortalaması arasındaki fark minimum -0.25, maksimum 2.6 dB HL olup, literatüre ile uyumlu bulunmuştur. Bulgular, yüksek frekans kelimelerin alçak frekans kelimelere göre daha iyi algılandığını göstermektedir. Konuşmayı ayırdetmede yüksek frekansların duyulmasının önemli olduğu gözlenmiştir.
