UMBRAL GUIDELINES FOR APPLICATION

OF DIRECTIVE 200/14 / CE
OF AUDITION The Purpose of Directive 2000/14 / EC, dated 8 May 2000, is to harmonize the laws

of the Member States regarding noise emissions, compliance procedures, marking,
technical documentation and data recording of noise emissions in the environ-
ment. outdoor use equipment environment.
The parameter adapted by the Directive to evaluate the noise emission level is the
considered (the generator set) measured in decibels (dB).
Alternatively, the generic indication of the noise level is the Acoustic Pressure Level,
1 0 bB GENTLE E which depends on both the sound energy emitted by the source, and the exposure

in Decibels (dB).
The two parameters are not independent. The Sound Power level can be calculated
