Noise Levels - Grillo 11500 Uso Y Mantenimiento

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).
