What do ear defenders do?
A physical barrier between the noise energy and the ear

Ear defenders form a physical barrier between the noise energy and the ear. Bypassing through the ear defender the sound loses energy and a lower energy sound means a quieter sound.
The process of losing noise energy is called attenuation, and it is the attenuation data that should be examined whilst selecting appropriate ear defenders. This data is available for all JSP ear defenders.
