I just made a quick video comparing the db on the two mini's.  I'm looking at around 5db difference and you can tell the Mini 2 is definitely quiter.  Enjoy!

Very helpful, thanks!  It's nice that they were able to both increase power and decrease noise at the same time.

Interesting comparison. Thanks.

Lucas,
Thanks for the comparison, there are a lot of improvements over MM1!

Thanks for sharing Lucas

Hi there Lucas, thank you for reaching us out and I appreciate the video you have shared. That is a good catch. Indeed the Mini 2 motors are improved compare with the Mavic Mini and also decrease the noise. This is a great video comparison. Always fly safe and thank you for your support.

Lucas,

Now that I own both I can see what an improvement the M2 is.

Good to see the improvement.

Excellent comparison

Cool! Thanks for sharing

Nice. Thinking of also picking up the Mini2.

I seriously think it's worth it, a whole lot better than the Mini 1.

Thanks, that is a good metric.  Sound can be issue for some of the places I would like to fly.  Neighbors only notice when I am flying because of the sound.  So less noise is better.  Is the pit of the Mini 2 less obvious then the original Mini?

I notice more low frequency components with the Mini 1. Is that phone app not A-weighted perhaps? A-weighting would decrease the low frequencies level indicated.

Edit: Being a retired test engineer, I had to try to duplicate your results of course ;-)
I used an SPL-8810 NIST traceable sound meter set to the A-weighted scaling. The drones were positioned aside the meter (not in front or rear), 3 feet away and at the same approximate level over the floor as the meter.

For the Mini, I measured 64-65 dba. The Mini 2 measured 62-64 dba.
The thing I noticed the most was that the Mini had more higher frequency components than the Mini 2. This I attributed to the more flexible props on the Mini. That seems to sound the opposite as your test.

Very welcome!

No problem!
