“…These findings corroborate research that found that older workers with a longer time of service are most vulnerable to hearing impairment. 9 27 It is noteworthy that the age factor may also affect the results, especially in high-frequency hearing thresholds, because those with longer service as a dentist are also older. 23 28 …”

Introduction High-level noise exposure in dentists' workplaces may cause damages to the auditory systems. High-frequency audiometry is an important tool in the investigation in the early diagnosis of hearing loss. Objectives To analyze the auditory thresholds at frequencies from 500 to 16,000 Hz of dentists in the city of Curitiba. Methods This historic cohort study retrospectively tested hearing thresholds from 500 to 16,000 Hz with a group of dentists from Curitiba, in the state of Paraná, Brazil. Eighty subjects participated in the study, separated into a dentist group and a control group, with the same age range and gender across groups but with no history of occupational exposure to high levels of sound pressure in the control group. Subjects were tested with conventional audiometry and high-frequency audiometry and answered a questionnaire about exposure to noise. Results Results showed that 81% of dentists did not receive any information regarding noise at university; 6 (15%) dentists had sensorineural hearing impairment; significant differences were observed between the groups only at frequencies of 500 Hz and 1,000, 6,000 and 8,000 Hz in the right ear. There was no significant difference between the groups after analysis of mean hearing thresholds of high frequencies with the average hearing thresholds in conventional frequencies; subjects who had been working as dentists for longer than 10 years had worse tonal hearing thresholds at high frequencies. Conclusions In this study, we observed that dentists are at risk for the development of sensorineural hearing loss especially after 10 years of service.

OBJETIVO: caracterizar o desempenho de escolares nos testes de padrão tonal de frequência e padrão tonal de duração no silêncio e na presença de ruído ambiental. METODO: trata-se de estudo experimental transversal, com amostra de conveniência, composta por 70 estudantes, que responderam a um formulário de percepção do ruído ambiental. O nível de ruído da escola foi avaliado com medidor de nível de pressão sonora. Os estudantes foram submetidos à avaliações (fala, motricidade orofacial, linguagem e simplificada do processamento auditivo) e distribuídos em dois grupos (G1 sem alteração fonoaudiológica e G2 com alteração fonoaudiológica). Foram realizados também os testes de padrão tonal de frequência e duração (silêncio e ruído). RESULTADOS: o nível médio de pressão sonora da escola variou de 57,2 dB(A) na sala de informática a 83,6 dB(A) na quadra de esportes. Segundo os estudantes, o que mais interfere em suas atividades é o barulho de conversas durante a aula. Quanto aos testes de padrão tonal de frequência (TPF) e duração (TPD), observou-se que a média de acertos no ambiente silencioso foi maior que no ambiente ruidoso. O G1 apresentou melhor desempenho no TPD e TPF que G2. No ruído houve piora no desempenho dos dois grupos (G1 e G2) nos testes. CONCLUSÃO: os níveis de pressão sonora da escola encontram-se elevados e fora do padrão recomendado pelas normas nacionais. No ruído, houve piora no desempenho dos testes nos dois grupos estudados.

“…The more rigid cutoff point adopted to identify hearing loss used here takes account of the fact that NIHL does not attain over 75 dB HL at high frequencies or 40 dB HL at low ones. 24,30 In relation the analysis of frequencies 3, 4, and 6 kHz (HL3), we observed that HL3 did not present good sensitivity. However, we found higher values compared with those for HL2.…”

Validity of hearTest Smartphone-Based Audiometry for Hearing Screening in Workers Exposed to Noise

Purpose This article investigates the validity of a smartphone-based audiometry for hearing screening to identify hearing loss in workers exposed to noise. Research Design This is a validation study comparing hearing screening with the hearTest to conventional audiometry. The study population included all workers who attended the Brazilian Social Service of Industry to undergo periodic examinations. Sensitivity, specificity, the Youden index, and positive (PPV) and negative predictive values (NPV) for hearing screening obtained by the hearTest were estimated according to three definitions of hearing loss: any threshold greater than 25 dB hearing level (HL), the mean auditory thresholds for 0.5, 1, 2, and 4 kHz greater than 25 dB HL, and the mean thresholds for 3, 4, and 6 kHz greater than 25 dB HL. Note that 95% confidence intervals were calculated for all measurements. Results A total of 232 workers participated in the study. Hearing screening with the hearTest presented good sensitivity (93.8%), specificity (83.9%), and Youden index (77.7%) values, a NPV (97.2%), and a low PPV (69.0%) for the identification of hearing loss defined as any auditory threshold greater than 25 dB HL. For the other definitions of hearing loss, we observed high specificity, PPV and NPV, as well as low sensitivity and Youden index. Conclusion The hearTest is an accurate hearing screening tool to identify hearing loss in workers exposed to noise, including those with noise-induced hearing loss, although it does not replace conventional audiometry.

Ruído e idade: análise da influência na audição em indivíduos com 50 - 70 anos

Abstract: The auditory thresholds of individuals with ages between 50 and 70 years are worse for the group that is exposed to noise. Noise is a higher risk factor than age when considering neurossensorial hearing losses.
