HF Acoustic noise

I hope someone can help me and measure the acoustic response of the SV06 (and plus) power supply using an FFT app. Hold the phones microphone close to the PSU when the printer is running and actuating all stepper motors.
For example Spectrum Analyzer by keuwelsoft:

Settings to measure as high frequencies as possible, minimum 44 kHz sample frequency is required.

I had issues with my MK3S+ which had a really loud high frequency acoustic noise from the PSU. Looks like this, so the HF noise above 15 kHz from the psu is louder than all other noises combined. Most people wont hear this so i home to get measurements
