- Translation and cross-cultural adaptation of the Noise Exposure Questionnaire (NEQ) to Brazilian Portuguese(2023) OLIVEIRA, Leticia Campos de; ROCHA, Clayton Henrique; MATAS, Carla Gentile; PAIVA, Karina Mary de; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra GiannellaObjective: To translate and cross-culturally adapt the Noise Exposure Questionnaire (NEQ) and 1-Minute Noise Screen (NEQ-S) instruments to Brazilian Portuguese. Methods: Procedures widely known in health research were used in the translation and cross-cultural adaptation process, comprising the following steps: initial translation, synthesis of translations, back-translation, expert committee, pretest, and content and layout validation. Altogether, 60 workers participated in the pretest by answering the questionnaires and then evaluating them in terms of understandability, layout, clarity, and writing. Reliability was verified with Cohen's kappa test, and the internal consistency was analyzed with Cronbach's alpha coefficient. Results: The translated and adapted versions of NEQ and NEQ-S were similar in terms of general and referential meanings. However, some modifications and adaptations were made to adapt them to the Brazilian reality. The kappa test indicated moderate agreement and Cronbach's alpha coefficient, substantial internal consistency. Conclusion: The translation and cross-cultural adaptation were carried out according to the methodology recommended in the national and international literature, performing the necessary equivalences to maintain the face and content validity with the original instrument. The availability of NEQ and NEQ-S in Brazilian Portuguese opens new fields of research to quantify yearly noise exposure more in-depth.
- Training in the proper use of earplugs: An objective evaluation(2020) TAKADA, Mirian Missae; ROCHA, Clayton Henrique; NEVES-LOBO, Ivone Ferreira; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra GiannellaBACKGROUND: Discrepancies between attenuation obtained in the laboratory and the field are caused by several factors associated with hearing protection devices (HPDs). The effects of some factors can be minimized with proper training provided to HPD users. OBJECTIVE: To evaluate the effectiveness of an educational intervention for improving the correct use of earplugs as HPDs in workers exposed to occupational noise by using the F-MIRE method and by comparing pre- and post-training attenuation values and pass/fail rates. METHODOLOGY: The personal attenuation ratings (PARs) of two types of earplugs were obtained (140 individuals) using E-A-Rfit (TM) equipment. Each HPD was evaluated under two scenarios: first after the user only read the packaging instructions, and then after the user read guidelines and participated in a training program. The results obtained were automatically classified by the software as ""Approved"" or ""Failed"". RESULTS: There was a significant post-training increase in the binaural PAR values for both HPDs. The percentages of passes pre- and post-training showed that training users in the proper fit of the HPD was effective; both types had statistically significant differences. CONCLUSION: This study found a statistically significant increase in PARs and the number of workers passing evaluations after HPD fit training, demonstrating the effectiveness of this educational intervention.
- Training on hearing protector insertion improves noise attenuation(2015) SAMELLI, Alessandra Giannella; ROCHA, Clayton Henrique; THEODÓSIO, Patrícia; MOREIRA, Renata Rodrigues; NEVES-LOBO, Ivone FerreiraABSTRACT Purpose: To determine the efficacy of hearing protector insertion by comparing attenuation values measured by objective (MIRE) and subjective (REAT) methods in groups with and without training. Methods: The study included 80 male subjects assigned to experimental (with training) and control (without training) groups. The following procedures were performed: occupational history, objective and subjective assessment of hearing protectors. Only subjects in the experimental group received training and guidance on proper hearing protector insertion. Results: Attenuation values were significantly higher in the experimental group than in the control group at all frequencies (500, 1000, 2000, and 4000 Hz) investigated through the objective (MIRE) and subjective (REAT) methods. In addition, attenuation values in the control group were lower than those provided by the hearing protector manufacturer. Conclusion: Both objective and subjective attenuation tests demonstrated the efficacy of training on insertion of hearing protectors because the group that received training on proper hearing protection insertion exhibited higher attenuation values than the untrained group.
- Effects of a vestibular rehabilitation program on workers in the working environment: a pilot study(2018) LONGO, Isadora Altero; NUNES, Ariane Diane Morais; ROCHA, Clayton Henrique; BRANCO, Fabiana Mara; MOREIRA, Renata Rodrigues; NEVES-LOBO, Ivone Ferreira; CASAROTTO, Raquel Aparecida; SAMELLI, Alessandra GiannellaABSTRACT Objective: to verify the effect of a vestibular rehabilitation program on workers with dizziness from the Division of Nutrition and Dietetics at a University Hospital. Methods: a total of 13 employees between 42 and 65 years of age participated, of whom, 1 was male, and 12, females. They were evaluated before and after the vestibular rehabilitation program using the Dizziness Handicap Inventory, Work Ability Index and Visual Analog Scale. The program was conducted in groups at the workplace. Statistical analysis was performed using the analysis of variance test for paired factors and the chi-square test. Results: in the pre- and post-vestibular rehabilitation comparison, significant differences were found in the Dizziness Handicap Inventory and Visual Analogue Scale scores. In the qualitative analysis of the Work Ability Index, an increase was observed in the number of workers who considered their ability to work to have improved. Conclusion: vestibular rehabilitation conducted in groups and in the working environment was effective in improving dizziness complaint in workers at the Division of Nutrition and Dietetics. It is believed that the positive experience of this program may be extended to other areas.
- Avaliação do protetor auditivo em situação real de trabalho pelo método field Microphone-in-real-ear(2016) ROCHA, Clayton Henrique; LONGO, Isadora Altero; MOREIRA, Renata Rodrigues; SAMELLI, Alessandra GiannellaABSTRACT Purpose To evaluate the effectiveness of the attenuation of a hearing protector (HP) in a real work situation using the field-microphone-in-real-ear method (f-MIRE). Methods Eighteen individuals of both genders (mean age of 47.17±8 years) participated in this study. In the workplace, the personal attenuation level of the HP was assessed using the f-MIRE method, followed by orientation about the importance of using the HP, cleaning and storing the device, and training for effective placement. Results The analyses showed a significant statistic attenuation for all of the collected data (total noise, by frequency band and dose) when the noise levels in the lapel microphone and the probe microphone were compared. In the comparison of the attenuation values provided by the manufacturer and those found in this study, we observed higher values for the manufacturer in all frequency bands. No difference was observed for the noise levels in the different activities and times evaluated. Conclusion The findings of this study enabled us to know the personal level of attenuation of the HP during a real work situation, which was within the limits of tolerance. It was also possible to collect information about the environmental noise to which these workers are exposed. We noticed situations where this level exceeded the safety values, and therefore it is recommended the use of the HP. It is important that more studies are conducted using the f-MIRE method, because it may be an ally to assess the effectiveness of the HP attenuation in the workplace.
- Noise Exposure, Headsets, and Auditory and Nonauditory Symptoms in Call Center Operators(2022) SILVA, Barbara Gabriela; GONZAGA, Denise; ROCHA, Clayton Henrique; GOMES, Raquel Fornaziero; MOREIRA, Renata Rodrigues; BISTAFA, Sylvio R.; SAMELLI, Alessandra GiannellaPurpose: This study evaluates the exposure of call center operators (CCOs) to occupational noise, its association with auditory and nonauditory symptoms, and the feasibility of monaural and binaural headsets. Method: We measured the noise exposure sound pressure levels (SPLs) with the microphone-in-real-ear technique and administered a questionnaire on auditory/nonauditory symptoms and headset preference. Results: We assessed 79 CCOs with normal hearing. Overall, 98.7% of the participants reported at least one auditory symptom, and 88.6% reported at least one nonauditory symptom after using the headset. We found significant associations between the headset volume setting and the number of auditory and nonauditory symptoms and between sharp increases in sound level and tinnitus. The microphone-in-real-ear diffuse-field-related SPLs with monaural headsets (85.5 dBA) were significantly higher than those with binaural headsets (83.1 dBA). Binaural headsets were the preference of 84.8% of the subjects. The SPLs of the binaural headsets were significantly lower than those of the monaural headsets in the subjects who preferred the binaural headsets. Conclusions: CCOs with normal hearing reported auditory and nonauditory symptoms, highlighting the need for attention and further investigation. The binaural headsets were preferable, as they were associated with a lower SPL and a higher call quality.
