| Resumen |
Air-fed protective helmets are used to protect workers from metal dust or particle projections, particularly during sand and shot blasting operations that are also associated with high noise levels. It was therefore interesting to determine whether these devices also protect the wearers from noise. At present, however, there are no regulations governing the noise attenuation properties of this equipment, and no standardized method for measuring the sound attenuation provided. This paper presents the implementation of the MIRE (Microphone In the Real Ear) measuring technique, which seems to be suitable for measuring the sound attenuation afforded by air-fed protective helmets. Minor sound attenuation is achieved by these protective devices, indicating the need for users of these devices to wear ear protectors when exposed to sound pressure levels higher than the legal limit. |
