“…However, we found significant correlations between the grade of dysphonia, breathiness, asthenia, instability and the values of Jitt, RAP, Shim, and APQ. Some trials reported similar findings in other vocal diseases [43], but to the best of our knowledge, no LPR study has previously noted possible correlations between the values of acoustic parameters and GRBASI score. Strangely, we did not found the classical correlations between hoarseness or roughness and acoustic parameter as found in other diseases.…”

BackgroundLaryngopharyngeal reflux is a prevalent, not well-understood disease affecting a high proportion of patients who seek laryngology consultation. The objective of this prospective case series is to explore the subjective and objective voice modifications in Laryngopharyngeal reflux (LPR), especially the usefulness of acoustic parameters as treatment outcomes, and to better understand the pathophysiological mechanisms underlying the development of voice disorder.MethodsForty-one patients with a reflux finding score (RFS) > 7 and a reflux symptom index (RSI) > 13 were enrolled and treated with pantoprazole 20 mg twice daily for three months. RSI, RFS, Voice Handicap Index (VHI), and Grade, Roughness, Breathiness, Asthenia, Strain and Instability (GRBASI) were assessed at baseline and after three months post-therapy. Acoustic parameters were measured by selecting the most stable interval of the vowel /a/. A study of correlations between acoustic measurements and laryngoscopic signs was conducted in patients with roughness. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS).ResultsSignificant improvement in RSI, RFS, VHI, jitter, percent jitter, relative average perturbation (RAP), shimmer, percent shimmer, and amplitude perturbation quotient (APQ) was found at 3 months of treatment (p < .05). A correlation analysis revealed significant correlations between the grade of dysphonia, breathiness, asthenia, instability and jitter, percent jitter, RAP, shimmer, percent shimmer and APQ. In dividing our cohort into two groups of patients according to the presence of roughness, shimmer, percent shimmer and APQ significantly improved in patients with roughness, but no positive correlation was found between acoustic parameters and laryngoscopic signs.ConclusionAcoustic parameters can help to better understand voice disorders in LPR and can be used as treatment outcomes in patients with roughness.

“…Measurements of Maximum Phonation Times (MPT), modal Sound Pressure Level (SPL), Dynamic Extension (SPL minimum and SPL maximum), acoustic vocal analysis of glottal and spectrographic sources were collected. The objective was to perform a multidimensional voice evaluation considering the complementarity of the different evaluations when a vocal profile is desired (Beber, Cielo, 2011, Beber, Cielo, 2012, Behlau et al, 2013, Cielo, Frigo, Christmann, 2013, Freitas et al, 2015, Pinho, 2003.…”

“…The acoustic analysis of the voice can be used to verify the glottal source, extracting different measurements that, when analyzed together, make it possible to understand the frequency, aperiodicity, stability and harmonic energy of the vocal signal (Cielo et al, 2015, Freitas et al, 2015.…”

The objective of this study was to verify the vocal measurements of athletes from an american football team from a municipality in the countryside of the state. With participation of eight men, aged between 18 and 39 years old (average of 24.25 years old). The collection of maximum phonation time of the vowels /a/, /i/, /u/, /s/, /z/, /e/ and number counting in normal pitch and loudness and the maximum phonation time of the [ė] was performed. Modal Sound Pressure Level and dynamic range were obtained by emission of /a:/. Acoustic evaluation of glottal and spectrographic sources. Maximum phonation times were below normality; the s/z ratio within the normality; the ratio ė/e below normality; the difference between vowels and number counting, the modal sound pressure level and the dynamic range were above normality. The acoustic vocal analysis showed impairment of the glottic source while the spectrographs were considered normal. In these American football athletes, pneumo-phono-articulatory incoordination with hyperfunctional characteristics and acoustic signal with presence of instability, aperiodicity and vocal emission failures were found, probably due to the incorrect vocal uses practiced in the sport.

“…Na análise acústica, conforme descrito por Titze, apenas sinais do tipo I poderiam ser avaliados de forma confiável pela análise acústica linear quando se trata de medidas dependentes da identificação do período do sinal, com as medidas de perturbação jitter e shimmer (TITZE, 1995 (DEJONCKERE, 1995;VAZ FREITAS et al, 2015).…”

“…Enquanto que para o shimmer há pesquisas que o encontraram correlacionado com a rouquidão e soprosidade (BEHLAU et al, 2001;LOPES et al, 2012) ou apenas com a rouquidão (VAZ FREITAS et al, 2015). A discrepância destes resultados pode estar envolvida com uma série de fatores, a começar pela forma de gravação vocal (DEJONCKERE, 2010) e as características distintas das diversas avaliações perceptivo-auditivas e acústicas.…”
