General-purpose earplug products frequently used at industrial sites attenuate sound too much, and thus it is hard to talk about work. If the earplug product is contaminated, it is impossible to use it again.
To overcome the disadvantages, the customized earplug for industrial purpose, developed by this company, minimizes communication inconvenience at work sites. In the case of the customized earplug, the work conditions of a person to wear the earplug are analyzed first, and then noise frequency is set up and noise filter is installed.
The customized earplug is made with soft silicone on the basis of a user's ear pattern, and thus it features a good sense of wearing. Even if it is polluted, it can be washed for semi-permanent reuse.
