          Abstract

          Introduction

          An air traffic controller is a professional who performs air traffic control functions in air traffic control units and is responsible for controlling the various stages of a flight.

          Objective

          To compare hoarseness and vocal tract discomfort and their risk factors among air traffic controllers in the approach control of São Paulo.

          Methods

          In a cross-sectional survey, a voice self-evaluation adapted from to self-evaluation prepared by the Brazilian Ministry of Labor for teachers was administered to 76 air traffic controllers at approach control of São Paulo, Brazil.

          Results

          The percentage of hoarseness and vocal tract discomfort was 19.7% and 38.2%, respectively. In relation to air pollution, the percentages of hoarseness and vocal tract discomfort were higher among those who consider their working environment to be intolerable than among those in a comfortable or disturbing environment. The percentage of hoarseness was higher among those who seek medical advice due to vocal complaints and among those who experience difficulty using their voice at work than among those who experience mild or no difficulty. The percentage of vocal tract discomfort was higher among those in a very tense and stressful environment than among those who consider their work environment to be mild or moderately tense and stressful. The percentage of vocal tract discomfort was higher among those who describe themselves as very tense and stressed or tense and stressed than among those who describe themselves as calm. Additionally, the percentage of vocal tract discomfort was higher among those who care about their health.

          Conclusion

          Among air traffic controllers, the percentage of vocal tract discomfort was almost twice that of hoarseness. Both symptoms are prevalent among air traffic controllers who considered their workplace intolerable in terms of air pollution. Vocal tract discomfort was related to a tense and stressful environment, and hoarseness was related to difficulty using the voice at work.

          Resumo

          Introdução

          O controlador de tráfego aéreo é um profissional que executa funções de controle de tráfego aéreo em unidades de controle de tráfego aéreo e são responsáveis por controlar as várias fases de um voo.

          Objetivo

          Comparar a rouquidão e o desconforto no trato vocal e seus fatores de risco em controladores de tráfego aéreo no centro de controle de aproximação de São Paulo.

          Método

          Em um estudo transversal, uma autoavaliação de voz adaptada da autoavaliação preparada pelo Ministério do Trabalho para professores foi administrada a 76 profissionais do centro de controle de aproximação de São Paulo, Brasil.

          Resultados

          A porcentagem de rouquidão e desconforto no trato vocal foi de 19,7% e 38,2%, respectivamente. Em relação à poluição do ar, as porcentagens de rouquidão e desconforto no trato vocal foram maiores entre aqueles que consideram seu ambiente de trabalho como intolerável do que entre aqueles em um ambiente confortável ou incômodo. A porcentagem de rouquidão foi maior entre aqueles que procuram assistência médica devido a queixas vocais e entre aqueles que têm dificuldade de usar a voz no trabalho do que entre aqueles que experimentam dificuldade leve ou não apresentam dificuldades. A porcentagem de desconforto no trato vocal foi maior entre aqueles em um ambiente muito tenso e estressante do que entre aqueles que consideram seu ambiente de trabalho leve ou moderadamente tenso e estressante. A porcentagem de desconforto no trato vocal foi maior entre aqueles que se descrevem como muito tensos e estressados ou tensos e estressados do que entre aqueles que se descrevem como calmos. Além disso, a porcentagem de desconforto no trato vocal foi maior entre aqueles que se preocupam com sua saúde.

          Conclusão

          Entre os controladores de tráfego aéreo, a porcentagem de desconforto no trato vocal foi quase o dobro da rouquidão. Ambos os sintomas são prevalentes entre os controladores de tráfego aéreo que consideram o seu local de trabalho intolerável em termos de poluição do ar. O desconforto no trato vocal foi associado a um ambiente tenso e estressante, e a rouquidão foi associada à dificuldade de usar a voz no trabalho.

          Populations in the U.S. workforce who rely on voice as a primary tool of trade: a preliminary report.

          The United States Bureau of Labor Statistics and other sources were consulted about the percentages of the working population that we identified as professional voice users. The largest percentage may be in sales and sales-related occupations (13%), but the exact breakdown of those who approach their clients vocally rather than by mail is still uncertain. The second largest population is teachers, who comprise 4.2% percent of the U.S. workforce (1994 statistic). Teachers have been identified as having the greatest incidence of voice disorders. Population data are also given for professional voice users who could present a significant hazard to public safety if their vocal communication skills were severely impaired.

              Variations in intensity, fundamental frequency, and voicing for teachers in occupational versus nonoccupational settings.

              In this study, the authors created a more concise picture of the vocal demands placed on teachers by comparing occupational voice use with nonoccupational voice use. The authors used National Center for Voice and Speech voice dosimetry databank to calculate voicing percentage per hour as well as average dB SPL and fundamental frequency (F(0)). Occupational voice use (9:00 a.m.-3:00 p.m., weekdays) and nonoccupational voice use (4:00 p.m.-10:00 p.m., weekends) were compared (57 teachers, 2 weeks each). Five key findings were uncovered: (1) Similar to previous studies, occupational voicing percentage per hour is more than twice that of nonoccupational voicing; (2) teachers experienced a wide range of occupational voicing percentages per hour (30+/-11% per hr); (3) average occupational voice was about 1 dB SPL louder than the nonoccupational voice and remained constant throughout the day; (4) occupational voice exhibited an increased pitch and trended upward throughout the day; and (5) some apparent gender differences were shown. Data regarding voicing percentages, F(0), and dB SPL provide critical insight into teachers' vocal health. Further, because nonoccupational voice use is added to an already overloaded voice, it may add key insights into recovery patterns and should be the focus of future studies.
