ABSTRACT
ABSTRACT

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.
RESUMO
RESUMO

Objetivo:

Determinar a eficácia da colocação do protetor auditivo comparando os valores de atenuação obtidos pelos métodos objetivo (MIRE) e subjetivo (REAT) em grupos com e sem treinamento.

Métodos:

Participaram do estudo 80 indivíduos do sexo masculino, separados em grupo pesquisa (com treinamento) e controle (sem treinamento). Os procedimentos realizados foram anamnese e avaliações objetiva e subjetiva do protetor auditivo. Apenas os indivíduos do grupo pesquisa receberam treinamento e orientações para colocar corretamente o protetor auditivo.

Resultados:

Os valores de atenuação no grupo pesquisa foram maiores com diferenças estatisticamente significantes em relação ao grupo controle em todas as frequências (500, 1000, 2000 e 4000 Hz) investigadas por meio dos métodos objetivo (MIRE) e subjetivo (REAT). Além disso, os valores de atenuação no grupo controle foram menores do que as previstas pelo fabricante do protetor auditivo.

Conclusão:

Ambos os métodos de avaliação da atenuação (objetivo e subjetivo) demonstraram a eficácia da colocação do protetor auditivo. Entretanto, o grupo que recebeu treinamento para colocação adequada do protetor auditivo apresentou valores de atenuação maiores do que o grupo sem treinamento.
