NOTES
1. dBA = A-weighted sound power level (A-scale according to IEC).
2. Reference acoustic intensity 0dB = 10E-6μW/m
3. Measured according to ISO 3744.
4. The operating sound level may become higher than this value depending on the operating
5. The power IeveIs have been caIcuIated in the assumption that the measuring point is
immediately under the source of operating sound.
