Noise emission

Danger due to noise
Exposure to noise can harm the hearing system, impair health and the psy-
chological state and may lead to lack of attention and irritation.
WARNING
When the engine is running, always wear ear protection.

Always wear ear protection if the sound pressure level exceeds 85 dB(A).

Wear ear protection.
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
near the filter silencer. The following prerequisites must be fulfilled with regard to the turbo-
charger to observe this limit value:
 Air-inlet system has been fitted
 All standard, noise-reducing measures
 Bellows at the air-outlet has been acoustically insulated by the enginebuilder (see Figure 19).
The enginebuilder is responsible for insulating the charge air/scavenging air line and the
charge air cooler.
