Noise Levels - Grillo 11500 Mode D'emploi

NOISE LEVELS

The machine's noise level was measured in accordance with the EN 709 standard by the Institute
of Agricultural Engineering, Bologna University.
The noise levels were measured using a Bruel & Kjaer measuring device, serial number 1178097,
complying with IEC804, IEC651-1I, ANSI S1.4-1983 and a B&K microphone complying with IEC651.
The noise levels were measured in an area free from obstacles over a radius of at least 20 m. and
with the engine at normal operating temperature.
The data given below refer to draft standard CEE PrEN 1553: 1994-annex B.
Ambient pressure 760 mmHg;
Temperature 3°C;
Relative humidity 85%;
Wind speed below 0.5 m/s (and thus the correction constant due to background noise is equal to
zero).
