Noise under dron

[alejandro cauich]

After an accident when landing the drone falls a little less than 1 meter, everything seems normal, then I notice that at the bottom where the sonic sensors are emits a noise like a nose if it is normal and I had not noticed or is it some error due to the fall, how are those sensors calibrated? , I would greatly appreciate your help

There is a cooling fan inside the Mavic

But before the fan on this noise begins is very low noise

Your crash landing may have done something to it.

Is it like a clicking sound or a low knocking sound?

Its like a clicking

Its like a clicking

Faint clicking seems to be normal.

It's ultrasonic pulses from the transducers. Seems like they also output frequencies detected by human ear.

I've never noticed mine but often wonder wether it's differences in the transmitter or that I just can't hear the frequency that some people can.

Clicking is natural. Vision Position Sensors.
