The Bonebridge ® (BB, Med-El) is a newly designed transcutaneous active bone conductive implant with functional outcome similar to percutaneous bone-anchored hearing systems (BAHS). It is currently approved only for patients ≥18 years. Since the BB allows the skin to remain intact and therefore should be able to overcome some of the issues related to(More)
BACKGROUND Vocal loading tests are an important element in the evaluation of vocal function. In Germany mostly tests with changes of loading intensity between 75 and 80 dB(A) or tests with continuous intensity of 80 dB(C) are used. MATERIAL AND METHODS 17 subjects with healthy vocal function were analyzed in 3 test conditions (1. continuous loading of 80(More)
OBJECTIVE Singing styles in Musical Theater singing might differ in many ways from Western Classical singing. However, vocal tract adjustments are not understood in detail. MATERIAL AND METHODS Vocal tract shapes of a single professional Music Theater female subject were analyzed concerning different aspects of singing styles using dynamic real-time(More)
The role of the vocal tract for phonation at very high soprano fundamental frequencies (F0s) is not yet understood in detail. In this investigation, two experiments were carried out with a single professional high soprano subject. First, using two dimensional (2D) dynamic real-time magnetic resonance imaging (MRI) (24 fps) midsagittal and coronal vocal(More)
Magnetic Resonance Imaging (MRI) of subjects in a supine position can be used to evaluate the configuration of the vocal tract during phonation. However, studies of speech phonation have shown that gravity can affect vocal tract shape and bias measurements. This is one of the reasons that MRI studies of singing phonation have used professionally trained(More)
PURPOSE To accelerate dynamic imaging of the vocal tract during articulation. MATERIALS AND METHODS Five subjects were imaged by magnetic resonance imaging (MRI) while repeating the word "Partikel" at 90 beats per minute, using both a radio-frequency-spoiled radial gradient echo sequence with golden angle projection rotation and a previously applied(More)
Human voice production at very high fundamental frequencies is not yet understood in detail. It was hypothesized that these frequencies are produced by turbulences, vocal tract/vocal fold interactions, or vocal fold oscillations without closure. Hitherto it has been impossible to visually analyze the vocal mechanism due to technical limitations. Latest(More)
PURPOSE Professional male altos (countertenors) mostly use a register function, which is considered to be derived from falsetto. However, the sound produced differs in professional altos compared with the modal register or falsetto of untrained voices. The aim of this study was to analyze differences of the vocal tract shapes in male alto register(More)
OBJECTIVE The role of the vocal tract in registers is still unclear. Professional western classically trained tenors may reach their top pitch range by modifying vocal register functions. The aim of this study was to analyze the influence of vowel conditions on vocal tract configurations in different register functions. MATERIALS AND METHODS Dynamic(More)
INTRODUCTION Previous studies using dynamic real-time magnetic resonance imaging (MRI) to analyze vocal tract configurations in singers are limited by the fact that the image acquisitions were performed in the supine position. The aim of this study was to examine differences of the vocal tract shape in professional tenors between supine and upright(More)
