Abstract

Se describe un protector para los oídos de espuma (o alveolar) para ser recibido por lo menos parcialmente dentro del canal auditivo, que incluye una porcion de cuerpo formada de un material de plástico alveolar que tiene una estructura celular abierta multiple y tiene un tamaño y una forma para ser recibido por lo menos parcialmente dentro del canal auditivo. Un recubrimiento delgado externo de un material elastomérico no permeable forma una superficie adherida sobre la porcion de cuerpo, no permeable al aire, por lo menos en el área de la porcion de cuerpo recibida dentro del canal auditivo. Esta estructura proporciona un incremento en la atenuacion del sonido en comparacion son la atenuacion del sonido producida por el material plástico alveolar resiliente sin el recubrimiento delgado del material elastomérico no impermeable.
