Abstract Background In the CoVID-19 pandemic, singing came into focus as a high-risk activity for infection with airborne viruses and was therefore forbidden by many governmental administrations. Objective The aim of this study is to investigate effectiveness surgical masks regarding spatial temporal dispersion aerosol droplets during professional singing. Methods Ten singers performed passage Ludwig van Beethoven’s “Ode Joy” in two experimental setups—each without masks. First, they sang...
Mucus consistency affects voice physiology and is connected to disorders. Nevertheless, the rheological characteristics of human laryngeal mucus from vocal folds remain unknown. Knowledge about viscoelasticity enables fabrication artificial with natural properties, more realistic ex-vivo experiments promotes a better understanding improved treatment dysphonia regard consistency. We studied samples two complementary approaches: 19 were successfully applied particle tracking microrheology...
Musical activities, especially singing and playing wind instruments, have been singled out as potentially high-risk activities for the transmission of SARS CoV-2, due to a higher rate aerosol production emission. Playing instruments can produce condensation, droplets saliva, particles, which hover spread in environmental air’s convectional flows be infectious. The aim this study is investigate primary impulse dispersion aerosols that takes place during different compared breathing speaking....

With age, the atrophy of thyroarytenoid muscle (TAM), and thus vocal folds, leads to decreased glottal closure, increased breathiness, a loss in voice quality, which results reduced quality life. A method counteract TAM is induce hypertrophy by functional electric stimulation (FES). In this study, phonation experiments were performed with ex vivo larynges six stimulated unstimulated ten-year-old sheep investigate impact FES on phonation. Electrodes implanted bilaterally near cricothyroid...
Abstract Group singing events have been linked to several outbreaks of infection during the CoVID-19 pandemic, leading activities being banned in many areas across globe. This link between and rates supports possibility that aerosols are partly responsible for person-to-person infection. In contrast droplets, smaller aerosol particles do not fall ground within a short distance after expelled by e.g. singer. Aerosol hover spread via convection environmental air. According super-spreading...
Laryngeal mucus hydrates and lubricates the deformable tissue of vocal folds acts as a boundary layer with airflow from lungs. However, effects mucus' viscoelasticity on phonation remain widely unknown has not yet been established in experimental procedures voice research. In this study, four synthetic samples were created basis xanthan focus physiological frequency-dependent viscoelastic properties, which cover viscosities elasticities over 2 orders magnitude. An ex vivo setup was expanded...
Abstract Background During the Covid-19 pandemic, singing activities were restricted due to several super-spreading events that have been observed during rehearsals and vocal performances. However, it has not clarified how aerosol dispersion, which assumed be leading transmission factor, could reduced by masks are specially designed for singers. Material Methods 12 professional singers (10 of Bavarian Radio-Chorus two freelancers, 7 females 5 males) asked sing melody ode joy Beethoven’s 9 th...
Introduction Group musical activities using wind instruments have been restricted during the CoVID19 pandemic due to suspected higher risk of virus transmission. It was presumed that aerosols exhaled through tubes while playing would be ejected over larger distances and spread into room jet stream effects. In particular, soprano recorder is widely used as an instrument in school classes, for beginners all age groups their education, context leisure professional concert performances....
Presbyphonia, an age-related decrease in voice quality is a consequence of vocal muscle atrophy. Functional Electrical Stimulation (FES) was introduced as potential treatment to increase the volume. In this study, we analyzed effects FES using ex vivo sheep larynx models. To stimulate thyroarytenoid muscle, electrodes were implanted at recurrent laryngeal nerve 12 (10 y). applied six for 9 weeks. Afterwards, excised larynges fixated mechanical setup and analyzed. For different elongations...
