Frequently Asked Questions
What is the measured sound pressure level at 1 meter?
The sound pressure level at 1 meter is 63 dBA.
At what frequency does the device produce its highest sound power spectrum reading?
The data shows multiple high readings (e.g., 68 to 70) around the 250Hz and 500Hz frequencies.
How is the acoustic spectrum data calculated?
It is calculated by adding the sound power levels of the compressor and fan motor at full speed, following EN13215 conditions.
Are enclosure effects considered in the noise evaluation?
Yes, the effect of noise reduction due to enclosure and insulation was considered for evaluating the sound power.
