Special models
All models can be fitted with a tiny metal ball (detection ball). These
specialised models are mainly of interest to the food and chemical industries.

• Filters are individually adjusted to the environment
•Important sounds and signals can still be heard
•Ideal comfort, hardly noticeable
•High user acceptance
• Easy to wear with safety helmets
• Almost invisible
• Easy to use
• Easy to clean
The standard material for all our models is silicone, which provides good
mechanical and chemical resistance combined with a long life span. The
soft, flexible material causes no pressure points in the ear canal, even with
prolonged wearing. The basic standard issue of the ear plugs is transparent
silicone, but they can also be produced from a harder acrylate plastic and
in a range of signal colours like red, blue or yellow.

The ear plug is custom moulded to each user and consists of the silicone plug
and the acoustic filter itself.
Before fitting the ear plug, a medical examination has to be carried out to
assess that it is safe to inject the moulding putty into the ear canal. During
this examination, excess cerumen (earwax) or cerumen plugs should be syringed
from the ear canal.
The moulding is performed according to current best practice for the fitting
of hearing aids. The moulding material is a pliable two-component putty
based on silicone. This is injected into the ear canal without any noticeable
pressure. The moulding process is normally not uncomfortable. The result is
a perfect copy of the ear canal and part of the pinna.
In the next production step, this mould is then used to form the final earpiece.
It fits perfectly into the ear canal and provides a tight fit. Then a hole is
drilled into the part that inserts into the ear canal. Now the appropriate
acoustic filter is fitted, specifically tuned to your requirements for noise reduction.
Compared to other systems, custom made hearing protection has many
advantages. It is anatomically fitted to each user’s ear canal, therefore can
neither slip nor cause pressure points and the protection is consistent throughout
usage. It doesn’t close up the ear canal completely, but is ventilated
through the acoustic filter, which also allows pressure equalisation. In this
way user comfort is maximised.
The large range of acoustic filters allows for a multitude of noise environments,
eliminating under- or over-protection.
