EP7 Sonic Defenders Ultra protect users’ hearing from dangerous noise levels—without interfering with their ability to hear ambient sounds and conversations. These affordable, non-electronic earplugs feature Hocks Noise Braker® filters that allow lower-decibel sounds to pass through, while potentially harmful sound levels above 85dB are reduced to safer levels.
Electromagnetic radiation (EMR) is a physical agent, but is not homogeneous. The physics, health effects and assessment methods differ over different regions of the EMR spectrum in the occupational environment. Examples of the sources of occupational exposure include radar systems, radio and TV broadcast systems, radiofrequency diathermy, dielectric heaters and sealers and communication equipment.
