NOTES
1 The sound pressure level is measured in an anechoic room at 1m distance from the unit. It is a relative value, depending on the distance and
acoustic environment. For measuring conditions: please refer to item 8 of this chapter.
2 The sound power level is an absolute value indicating the ’’power’’ which a sound source generates.
