NOTES
1. Operation sound is measured in an anechoic chamber.
2. The operating sound level may become greater than this value depending on the
operating conditions, reflected sound and peripheral noise.
3. Operation sound differs with operation and ambient conditions.
4. The power IeveIs have been caIcuIated on the assumption that the measuring point were
right under the source of operating sound.

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.
