This paper studies high registers of heavy metal singing based on the voice profile analysis scheme (VPAS) and acoustic correlates. The f0 range varied from 366 to 666 Hz. The application of VPAS for singing is unique in the phonetic literature. Two professional and two amateur singers sang Iron Maiden’s Aces High with instrumental playback through headphones. Two very high-register excerpts we...

The goal of this investigation was to test a new methodology for measuring amplitude modulation (AM) at the level of the vocal folds during vibrato in trained singers, because previous research has suggested that AM arises in large part as an acoustic epiphenomenon through an interaction of the harmonics in the laryngeal source with the resonances of the vocal tract as the fundamental frequency...

Although there have been numerous investigations of laryngeal muscle activity during during phonation in the chest and falsetto/head registers in trained and untrained classical singers and non-singers, no research has been conducted examining laryngeal muscle activity during phonation in the chestmix register, a register used extensively by many female commercial singers, particularly for the ...

AGAINST THE BACKGROUND of the debate on quality assurance in nonprofit organizations (Chaffee and Sherr, 1993) and growing economic constraints on nonprofit professional opera companies (Coe, 1994), the issue of measuring artistic performance in opera companies comes to the fore. The management literature has explicitly discussed quality and quality management since the end of the 1980s (Hackma...

Advances in genetic research have created the need to inform consumers.Yet, the communication of hereditary risk and of the options for how to deal with it is a difficult task. Due to the abstract nature of genetics, people tend to overestimate or underestimate their risk. This paper addresses the issue of how to communicate risk information on hereditary breast and ovarian cancer through an on...

PURPOSE To map voice handicap of popular singers with a general voice and two singing voice self-assessment questionnaires. METHODS Fifty singers, 25 male and 25 female, 23 with vocal complaint and 27 without vocal complaint answered randomly the questionnaires. For the comparison of data, the following statistical tests were performed: Mann-Whitney, Friedman, Wilcoxon, Spearman and Correlati...

A simple restatement of the developmental stress hypothesis is that certain attributes of bird song are honest indicators of sig-naler quality because of their developmental costs. Spencer and
