Noise emission

Danger due to noise
Exposure to noise can harm the hearing system. It can impair health and the
psychological state and may lead to irritation and lack of attention.
WARNING
When the engine is running, always wear hearing protection.

Always wear hearing protection if the noise level exceeds 85 dB(A).

The emission sound pressure level (A-weighted) is measured at a distance of 1 meter from
the turbocharger.
The highest value of the emission sound pressure level
silencer and is 105 dB(A) maximum over the entire speed range.
The following prerequisites must be fulfilled with regard to the turbocharger to observe this
limit value:
 Air-inlet system has been fitted
 All standard, noise-reducing measures
 Bellows at the air-outlet has been properly acoustically insulated by the enginebuilder (see
Figure 23).
The enginebuilder is also responsible for insulating the charge air/scavenging air ducts and
the charge air cooler.
