“…Such changes in the mucosa and in the vocal muscle could justify an increase in the perturbation measurements in the elderly population. In spite of the increase in the shimmer measurement in the elderly population in relation to adults, when two groups of elderly women were compared, the older one did not present differences in relation to the younger 23 . Another study that investigated young and elderly women did not find change in the shimmer measurement between the groups 25 .…”

“…In old age, there are physiological changes -such as alterations in glottal closure, asymmetry and irregularity in vibration of vocal folds 24 , which could justify increase in jitter measurements. Despite this, other studies that investigated the elderly's voice indicate that this measurement remains stable in old age and does not reflect the changes resulting from the aging process 8,23,25 , although they comment that, with aging, the vibration of the vocal folds becomes less symmetric and with greater vibratory irregularity. Thus, it was observed that there is no consensus between the studies regarding the behavior of jitter measurements in the elderly population.…”

“…With aging, the human voice goes through changes noticeable in F 0 , particularly in women. In general terms, in women, there is a decrease in F 0 measurements in the elderly population in relation to young women 8,19,23,24 . The decrease in F 0 found in the literature is justified by the anatomic and hormonal changes taking place in the human larynx 8,12,19 , as age advances.…”

Acoustic characteristics of voice in different cycles of life: an integrative literature review

Purpose: to carry out an integrative literature review about the acoustic characteristics of healthy voice production, from childhood to old age. Methods: a bibliographic survey was conducted on the databases PubMed, SciELO, MEDLINE and LILACS, covering the last 10 years. Nineteen studies were found, meeting the proposed criteria, on acoustic measurements: F0 (fundamental frequency), jitter, shimmer and/or noise measurements, in males and females, with normal voices in their different stages of life. Results: the analysis showed that F0 is the most changing acoustic parameter as people grow up and grow old. Its values present gradual fall from childhood to old age in the female population, whereas among men such decrease lasts until adulthood. Jitter, shimmer and noise remain stable throughout childhood and adulthood, while shimmer and noise measurements increase in old age. In the literature, there is no consensus regarding increase of jitter measurements in the elderly. Conclusion: from childhood to old age, in both genders, vocal changes take place which are reflected, especially by F0. There is a scarcity of information on acoustics related to specific populations with ample age range, using the same methodology. The information in this study may guide future investigations aiming to understand natural changes occurring in the human voice, in addition to guiding in the clinical practice.

“…Two participants (57 and 66 years old) reported worsened vocal quality because of advancing age, which they first noticed at 45 and 50 years old, respectively. Throughout life, women experience continuous fluctuations in hormone levels, so their larynxes -and in fact entire bodies -feel the effects of these changes at puberty, during each menstrual cycle, during pregnancy, as well as at menopause (8,9,15,29,30) . Consequently, the dynamics of voice use and guidelines about vocal health need to be differentiated to ensure better support and more efficient use of the voice in light of the limitations aging imposes (15) .…”

“…Historically, hormonal changes, the premenstrual period, menopause, and thyroid surgeries comprised the most common vocal problems women suffered from (15) . Currently, however, women's voices face additional challenges, such as the adoption of a lifestyle that can involve alcohol, tobacco, and drugs; professions that propel women into leadership positions but also result in higher stress, overuse of the voice, and potential contact with toxic chemicals; the use of medications that interfere in vocal physiology; and increased longevity (16,17) .…”

Quem canta seus males espanta." Conhecimento e uso da voz como recursos promotores da saúde de coralistas "Quien canta, a los males espanta." Conocimiento y uso de la voz como recursos de promoción de la salud de coralistas ABSTRACT Objective: To comprehend the knowledge and use of the voice by female choristers and the implications for health promotion, according to their interpretations. Methods: A qualitative study was conducted from December 2011 to February 2012 with 13 women aged 23 to 66 years old, members of a university chorus, in Fortaleza, Ceará, Brazil. A semi-structured interview was used for data collection. Thematic analysis was used to organize the results into categories, which were analyzed according to the symbolic interactionism. Results: Two core meanings were identified: knowledge regarding the voice and the use of the voice. The participants defined the voice as a means of communication, a personal identity, and a way to express feelings. They did not show consistent knowledge of the anatomical or physiological aspects of the voice, but the given definitions show they understand that the voice permeates personal, social, and professional spaces. The professional voice and aging emerged as two of the most prominent issues in the context of the vocal use. The participants recognize that knowledge and use of the voice can be improved by the activities in the choir, which leads to health promotion. Conclusion: The choristers show limited knowledge about vocal health, yet they comprehend the beneficial effects of chorus on women's health, raising their understanding of vocal health; that stimulates the adoption of healthy habits and preventive measures, which favors the vocal use.

Purpose Approximately 30% of adults over the age of 50 years present with altered vocal function. Our understanding of how these changes manifest acoustically and perceptually is derived from relatively modest-sized studies using a diversity of tools. Voice changes can arise from the onset of disease or disorder, but also age-related physiological changes, which may not reflect pathology as such. Here, we bring together data on acoustic, perceptual, and instrumental assessments (electroglottography), with the aim of gaining a better understanding of the changes occurring across these measurement domains. We consider these changes in the context of different acoustic features, software programs, and perceptual protocols. Method Studies of voice function in healthy older adults over the age of 50 years were sought. Literature was systematically searched with 746 abstracts reviewed. Forty-seven studies were included in the review. A meta-analysis of included studies compared voice acoustic parameters between sex and age. Sixteen acoustic parameters collected from 1,475 participants were analyzed in the meta-analysis. These included some previously unpublished analyses using data provided by authors of included studies. Results Data from the systematic review suggest that older individuals are perceived to present with higher overall scores of dysphonia and roughness, breathiness, strain, and instability. Acoustically, males have significantly higher scores on measures of perturbation, including noise-to-harmonic ratio and absolute jitter. The meta-analysis outcomes suggest that participants aged 80–89 years produce significantly higher fundamental frequency, jitter percent, shimmer percent, and shimmer in decibels compared to participants aged 60–69 years and a significant increase in relative average perturbation, jitter percent, and shimmer in decibels compared to participants aged 70–79 years. Limited data were available comparing acoustic measures using the same acoustic software. Conclusions Variations in fundamental frequency and frequency and amplitude perturbation increase as healthy adults age. It was difficult to draw definitive conclusions based on existing literature due to variability in hardware used, limited descriptions of study cohorts, or missing data from statistical analysis.
