Comparison of voice properties between opera and pop female singers

Popis výsledku v původním jazyce

Singing genres differ not only in their musical characteristics, but also in the technique of voice production and the subsequent acoustic quality of the voice. The aim of this work is to compare perceptual, acoustic, electroglottographic and radiation properties of voice classical and pop female singers. Six opera female singers and 5 pop female singers participated in study. Sound radiation properties were measured using 44 microphones. Synchronously audio and electroglottographic signals were taken while singing scales ranging from C4 to C6 using 4 dynamic levels and gradually increased intensity from 9 chosen tones. The analysis was done for the vowels /a/, /i/ and /u/ and was performed on 0.5 s long samples. Classical singers have more omnidirectional sound radiation patterns than pop singers. Opera singers generally reached higher maximum SPL levels in C5-C6 octave. Pop singers achieved maximum SPL levels in the middle of C4-C5 octave for vowel /a/ only. The most significant EGG difference concerned mf and ff dynamic levels in the range of one and a half octaves, where the voice of pop singers showed higher values of contact quotient. Moreover, systematic differences were found for the shape of EGG pulses (from wavegrams) with increasing pitch. Pop singers gradually reduced the amplitude in the decontacting part of wavegram, while opera singers gradually increased it. Spectral analysis showed that opera singers enriched the sound particularly in ranges of the first formant or the first harmonics (200 - 800 Hz) and between 2 and 5 kHz by bringing the positions of third, fourth and fifth formants slightly together. Pop singers had significantly higher energy values in higher parts of vocal range.
