This dissertation, in collaboration with the Thomas Edison National Historical Park, recorded 20 professional opera singers on a flat-response microphone array and a period wax cylinder phonograph simultaneously, and subsequently digitized the cylinder recordings using an Archéophone. However, past inquiry has not specifically studied the effect(s) of historical audio recording technology on the voice output signal. The fields of vocal pedagogy, singing voice research, vocal performance, and musicology have each studied different aspects pertaining to the development of the operatic voice since the advent of audio recording technology. Elektroglotografik ana-lizlerde, her iki şarkıcının da göğüs registerini kullandıkları ve perde artışına CQ Uygulama aşamasında, farklı perdelerde seslendirilen sesli fonem örneklerinin yanısıra, konuşma ve şarkı söyleme örnekleri de kaydedilerek analiz edilmiştir. Öz Bu çalışmada, Düzce ilindeki iki farklı kültürel toplumu temsil eden iki şarkıcının sesleri akustik olarak ve register açısından incelenmiştir. Thus, we concluded that they made their voice hearable thanks to this situation. But, at LTAS graphs of singers it appeared that the region where the fundamental frequency of their singing voice came into being, was almost empty in spectrum of instruments, and the energy level of singer's fundamental frequency was very high. In the LTAS of instruments that accompanied to them, the region of FCwos and P3-4kHz was very high in respect of energy level. It was seen that, the production of both two acoustical phenomenon supported by neither vocal tract properties nor glottal settings: their F3, F4 and F5 stood apart from each other, and thus they did not contribute each other in energy and their CQ value was low. After the analysis process, we concluded that neither FCwos nor P3-4kHz existed in the spectrum of performance and normal speech voice spectrum. It was found that they used chest register in voice production and as frequency increased, the value of CQ increased as well.


In application process, the vowels which singers produced at various pitches in isolation, the samples of speaking texts and singing song were recorded in a soundproof room. In this study we investigated the register phenomenon and spectral characteristics of two singers that represent two different cultural communities settled in Duzce, one of the provinences of Turkey.
