Solo singers have been shown to over estimate the relative sound pressure level of a delayed, external reproduction of their own voice, singing single syllables, which, in turn, appears to influence the preferred delay of simulated stage reflections. Singer's preferred acoustic condition in performance in an opera house and self-perception of the singer's voice Whilst there are clear differences in contact quotient between subjects, particularly when relationships between fundamental frequency (f0) and contact quotient (Qx) are considered, there is no apparent link between contact quotient behaviour and performance specialism based on the results of this sample.

Electroglottography was used to consider vocal characteristics idiomatic to each genre. Voice source comparison between modern singers of early music and opera.Īn experiment was conducted comparing two subject groups, each comprised of eight professional singers specializing in a genre of classical music: early music or grand opera. This case highlights the importance of the risk of vocal fold hemorrhage to professional singers and professional voice users and offers an alternative to long-term coumadin therapy in this select population. We present a case of an opera singer who developed recurrent vocal fold hemorrhage associated with coumadin anticoagulation therapy. The risk factors of vocal fold hemorrhage, including laryngeal trauma, phonotrauma, aspirin and nonsteroidal antiinflammatories, and hormonal imbalances are well known. Vocal fold hemorrhage can represent a disastrous and potentially career ending injury to a singer or professional voice user.
