A common reason for neglecting to use proper hearing protection is that the wrong choice was made in the

first place. More sophisticated hearing protection than the situation demands can be perceived as uncom-

fortable and it becomes unnecessarily difficult to understand speech and signals. But how do you know

what’s right for you?

The basic rule is that you must always (100% of the time!) wear hearing protection if you are in an envi-

ronment that has an A-rated noise level of 85 dB. The noise level, in combination with how long you are

exposed to it, determines just how damaging this noise-hazard environment is to your ear. For example, 8

hours of exposure to an 85 dB A-rated noise level delivers the same harmful dose as 15 minutes of expo-

sure to a 100 dB A-rated noise level.

High tones, high volume...

Optime I. Good muffling, especially in the high-frequency range. The nature of this muffling protection permits

extremely good communication potential.

+ lower tones and higher volume...

Optime II. Increased muffling, primarily for lower frequencies. This first-rate muffling, which even covers high fre-

quencies, gives suitable protection in most noise-hazard situations.

+ bass tones and extremely high volume

Optime III. Extra noise muffling for both low and high frequencies, intended for particularly high noise levels. This

protection meets the most stringent muffling demands.
