Migraine attacks are often preceded by premonitory symptoms. Prevalence rates of migraine patients reporting one or more premonitory symptoms show considerable variability and rates range between 12% and 79%. Sources of variability might be differences in study population or research design. Using a questionnaire, we retrospectively studied the prevalence of 12 predefined premonitory symptoms i...

Long-term-average spectrum (LTAS) is an efficient method for voice analysis, revealing both voice source and formant characteristics. However, the LTAS contour is non-uniformly affected by vocal loudness. This variation was analyzed in 15 male and 16 female untrained voices reading a text 7 times at different degrees of vocal loudness, mean change in overall equivalent sound level (Leq) amounti...

Voice source characteristics as derived from inverse filtering were analyzed in 6 country singers' speech and singing. Results showed that the closed quotient varied systematically with vocal loudness, and that glottal compliance (the ratio between transglottal AC volume displacement and subglottal pressure) decreased with increases in fundamental frequency but remained unaffected by vocal loud...

IntroductionThe prevalence of headache and sleep disorders is quite high in the general population. Both are chronic pathologies considered factors daily disability which often coexists migraine patients. A cause-and-effect relationship between attacks sleepless nights has not been confirmed yet, but it already recognized that they have common neuropeptides functional anatomy their pathogenesis...

Changes in vertical larynx position during singing were studied in professional singer subjects using the two-channel electroglottograph recently presented by Rothenberg (1992). The evaluation of the method and the examination of the laryngeal behaviors of professionnl singers were the main aims of the study. The significance of pitch, vocal loudness and lung volume to vertical larynx position ...

The diagnosis of tinnitus relies on self-report. Psychoacoustic measurements of tinnitus pitch and loudness are essential for assessing claims and discriminating true from false ones. For this reason, the quantification of tinnitus remains a challenging research goal. We aimed to: (1) assess the precision of a new tinnitus likeness rating procedure with a continuous-pitch presentation method, c...

BACKGROUND contextual cues intrinsic to speech stimuli can have an influence on speech intelligibility measurements; however, the influence of cues that depend on the acoustic signal, such as speech rate and vocal loudness, need further investigation. AIM to examine whether possible reductions in the articulatory rate and increase in vocal loudness, associated to the production of different s...

We examined the influence of background noise on levels of problem behavior and pain behavior under functional analysis conditions for a child with a diagnosis of Williams syndrome and hyperacusis. Background noise was associated with increases in escape-maintained problem behavior and increases in pain behavior such as clasping ears and crying. When the child was fitted with earplugs, there we...
