2.4.1.1 Fitting accuracy of ear moulds
The CT-ClipCom digital communication system combined with personalised ear moulds / earpieces is
considered a personalised hearing protector which has been tested and certified within the scope of the
EC-type approval as personal protection equipment in the meaning of the European Directive
89/686/EG.
The sound insulating effect of a personalised ear mould depends principally on the proper accurate fit
and the personal ergonomics of the user.
For this reason, CeoTronics recommends to check the fitting accuracy of personalised ear moulds by
making acoustic measurements. Only this way it is possible to assure an appropriate sound insulating
effect of your ear mould.
For this purpose CeoTronics has developed a special testing system.
A sound insulation measurement made by this testing system, duly documented by a test certificate,
proves that the personalised ear moulds provide sufficient sound insulation.
Please note that this is a qualitative measurement and therefore the results must not necessarily
coincide with statistically ascertained values of subjective sound insulation experienced by 16 test
persons in the type approval test, as these are two different measuring methods.
Experience shows that that actual personal sound insulation values are slightly higher than the values
measured by the CeoTronics testing system. As the lower limits are used the minimum sound insulation
values of the EN 352-2 Standard.
In rare individual cases it is possible that no satisfactory sound insulation can be achieved in spite of
maximum care exercised in the process of taking impressions and manufacturing the ear moulds.
In such cases our earplugs can be used, however no specific certification is available for use together
with the CT-ClipCom digital communication system.
Wear of ear moulds varies individually; we recommend regular examination by measuring the moulds
with the CeoTronics testing system or replacement of your personalised ear mould after 2 years.
Kindly contact our customer consultants in case you want to test your personalised ear mould or clarify
any further questions regarding this subject.
