Noise emission
WARNING
Noise hazards
Exposure to noise can harm the hearing system, impair health and the psy-
chological state and may lead to lack of attention and irritation.
u
When the engine is running, always wear ear protection.
u
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 metre from
the low-pressure and high-pressure stage.
The highest value of the emission sound pressure level1) reaches a maximum of 105 dB(A)
near the compressor end (compressor casing, filter silencer, air suction branch).
The following prerequisites must be fulfilled with regard to the low-pressure and high-pres-
sure stage to observe this limit value:
¡
Air inlet system and piping fitted
¡
All standard, noise-reducing measures
2)
have been fitted
The enginebuilder is also responsible for insulating other components such as the charge
air/scavenging air lines and the cooler.
1)
Directive 2006/42/EC, 1.7.4.2 / u / Paragraphs 5 + 7:
A-rated emission sound pressure level
2)
The enginebuilder must provide acoustically equivalent measures in case of deviating in-
sulation versions
