“…Regarding hearing health, studies indicate the presence of damages on the peripheral (3,(5)(6)(7) and central (3,(8)(9)(10)(11) auditory system as well as hazardous effects on the vestibular system (6,12,13) . Impairments can be observed in the motility of the outer hair cells within the organ of Corti, progressing to the inner hair cells, auditory nerve, brainstem, and cortical regions, while in the vestibular auditory system, the author found lesions in the hair cells of the crista ampullaris in the saccule and the utricle (3) .…”

“…It is necessary to conduct an audiological monitoring and enroll the workers in Hearing Conservation Programs (HCP) (2,7,9,11,12) , since there is evidence that hearing impairments may be related to endogenous intoxication by pesticides (4,14) and can be considered an early manifestation of chronic intoxication by said chemical agents (4,14) . Nevertheless, the studies that investigated the hearing of workers exposed to pesticides are composed mostly of male participants.…”

Purpose To analyze the possible differences among the hearing of farmers and their families when compared to the population not exposed to pesticides. Methods Cross-sectional study with 70 smallholder family farmers (research group), with the mean age of 39.7 years, of both sexes and a mean of 23.7 years of exposure to pesticides. We included a control group with 71 participants of both sexes with the mean age of 39.5 years, not exposed to either noise or chemical substances, to compare the results. In stage 1, both groups were submitted to conventional and high-frequency audiometry, and acoustic immittance. In stage 2, only people with normal hearing were submitted to the evoked otoacoustic emissions and suppression effect on transient otoacoustic emissions. Results Significant differences were observed between the groups in the conventional pure-tone and in the high-frequency audiometry, as well as in the acoustic reflex. The most affected frequencies in the conventional pure-tone audiometry ranged from 3 to 6 kHz and, in the high-frequency audiometry, from 9000 to 11200 Hz. As for the transient otoacoustic emissions, the worse suppression effect results were found in the research group. Conclusion There were differences among the hearing of family farmers and the control group. The conventional auditory thresholds are related to the group, age and sex. Farming is associated with impairments in the basal region of the cochlea, absence of acoustic reflex, reduced signal-to-noise ratio of the transient otoacoustic emissions, and dysfunction in the olivocochlear efferents of the auditory system.

“…Na clínica audiológica, a configuração audiométrica descendente é repetidamente encontrada nas perdas auditivas sensorioneurais. Esse fato pode ser explicado pelo acometimento inicial das frequências agudas em diversas patologias do sistema auditivo, como as originadas pela exposição excessiva ao ruído, doenças metabólicas, ototoxicidade e presbiacusia (11,12) .…”

RESUMO Objetivo Verificar a correlação das diferentes médias tonais (tritonal, quadritonal e octonal) com o Índice Percentual de Reconhecimento de Fala e com a desvantagem auditiva. Métodos Participaram do estudo 56 sujeitos, distribuídos em dois grupos, com configuração audiométrica descendente: Grupo 1 (G1) - 28 sujeitos com média tritonal igual ou inferior a 25 dBNA e Grupo 2 (G2) - 28 sujeitos com média tritonal pior que 25 dBNA (G2), sendo pareados quanto ao gênero e idade (p= 0,544). Todos foram submetidos à audiometria tonal liminar, Índice Percentual de Reconhecimento de Fala (IPRF) com lista monossilábica de palavras gravadas, medidas de imitância acústica e ao questionário Hearing Handicap Inventory for Adults. A análise de correlação foi realizada entre as médias de três frequências (M3), de quatro frequências (M4) e de oito frequências (M8) com o IPRF e com a desvantagem auditiva, utilizando o teste de correlação de Spearman, sendo o nível de significância considerado <0,05 (5%). Resultados Evidenciou-se correlação estatisticamente significativa do IPRF com a M8, para o G1, e do IPRF com M4 e M8, para o G2. Observou-se tendência à significância, tanto para o G1, como para o G2, em relação à M8, quando correlacionada com a desvantagem auditiva, demonstrando que analisar as oito frequências do audiograma (frequências mais agudas que 4000 Hz) parece possibilitar maior compreensão em relação à desvantagem auditiva do paciente. Conclusão Houve correlação estatisticamente significativa do IPRF com a M8, nos dois grupos, denotando uma redução no desempenho do IPRF, com o aumento da média, considerando as oito frequências. A M8 refletiu melhor a desvantagem auditiva causada pela perda auditiva, no G1.

“…In clinical audiology, the descending audiometric configuration is repeatedly found in sensorineural hearing loss. This fact may be explained by the initial involvement of the acute frequencies in several pathologies of the auditory system, such as those caused by excessive noise exposure, metabolic diseases, ototoxicity, and presbycusis (11,12) .…”

Purpose To verify the correlation of different tonal means (tritonal, quadritonal and octanol) with the Percentage Index of Speech Recognition and with hearing disadvantage. Methods 56 subjects participated in the study, distributed into two groups, with descendant audiometric configuration: Subjects with tritonal average equal to or less than 25 dB HL(G1) and subjects with a tritone average worse than 25 dB HL(G2), being matched for sex and age (p=0.544). All were safe by Threshold Tone Audiometry, Speech Recognition Percentage Index (IPRF) with a list of keywords, Acoustic I Measures and the Elearing Handicap Inventory for Adults. The correlation analysis was performed between the averages, of three frequencies (M3), of four frequencies (M4) and of eight frequencies (M8) with the IPRF and with auditory disadvantage, using the Spearman correlation test, the significance level being considered <0.05 (5%). Results There was a statistically significant correlation of the IPRF with M8 , for G1, and the IPRF with M4 and M8, for G2. There was a tendency towards significance, both for G1 and G2, in relation to M8 when correlated with hearing impairment, demonstrating that analyzing the eight frequencies of the audiogram (frequencies higher than 4000 Hz) seems to allow a greater understanding of the patient’s hearing handicap. Conclusion There was a statistically significant correlation between the IPRF and M8, in both groups, denoting a reduction in the performance of the IPRF, with an increase in the mean, considering the eight frequencies. M8 better reflected the hearing disadvantage caused by the hearing loss in G1.
