No hearing protection suits every environment, so you should choose hearing protection for the actual noise environment you work in. That way you will be sure of the right attenuation for your particular situation. You must also take into account the length of time you are exposed to the noise. If you don’t wear earmuffs the whole time, you may sustain irreparable damage to your hearing. Hellberg’s hearing protection is available in three versions.
 

 Our HML method will help you determine which of these earmuffs best suits your working environment.
 

Ear cups can be swung outwards to a resting position around the neck.

Can also be fitted with Hellberg's face protection.

 The hearing protection also available for helmet mounting.
