More Blades Less Noise | DJI Neo | T-Mount Propeller Adapter

[@PedroFandango]

thanks, you've convinced me to stick with the stock blades

[@tatagiba]

kkkk me too

[@shawnstone4949]

Seems just different pitch,same loudness…

[@billmcdonald4335]

Hmm. To my ear the 6-blade props doubled the screeh frequency without much reduction of overall level. The 5-blade props sounded a little quieter, at least. However, a 135g 2-inch with excess material in the way of the prop thrust is always going to sound like a stuck pig. Physics is physics. Snip off those hoops on the bottom and you'll hear a bigger difference, I'll bet. It'll fly better, too.

[@quadmovr]

the perceived volume of the 6 blade is higher because of the higher frequency but actually the measured volume (dB) is quite a bit lower compared to the 3 blade. you are right, with more structures in the way of the air stream, there are more turbulences which increases the noise.

[@armands672]

@billmcdonald, are you talking about the bottom prop guard of neo?

[@betelgeusealphao]

2 blades may be a still lower frequency 😂

[@BlairAir]

​@betelgeusealphao Taking that logic to a reasonable conclusion, zero blades would be tge quietest, since negative numbers of propulsion devices is not achievable, though power would also be zeroed out.

[@joaomarveloso1049]

Did you feel any difference in the control and stability of the drone?

[@christophfoecking5828]

Sehr systematisch und konsistent verglichen. Top!

[@SpexFPV]

"Manual mode, fly with caution" Neo: "WEEEEEEEEEEEEEEEEEEEEEEEEEE"

[@chrisbee5481]

4 blade gemfan 2036 were most quiet to my ears in an experiment I did myself

[@quadmovr]

unfortunately i dont have them at hand.

[@raymondchan3587]

No, from my experience. I had them all.

[@DadRandom]

More blades more air getting smashed by them. Love the turbofan noise 🎉

[@felixbonobo]

Danke für den Direktvergleich. Die Frequenzen sind alle etwas Nervtötend, die Originalen sind da für meine Ohren noch am angenehmsten.

[@dogswhistlesharam9029]

Can you provide links for purchasing of each type pls? ..🤔🤔🤔

[@gregdavidd]

Hmm I wonder if somehow the difference didnt translate well into this video because the stock seems the lowest pitch. Its the high pitch that is annoying. Thats why the Avata 2 is so much less annoying than the original Avata.

[@quadmovr]

there not much difference. the perceived volume of the 6 blade is higher because of the higher frequency but actually the measured volume (dB) is quite a bit lower compared to the 3 and 5 blade. what makes the neo loud is not the props itself but the shell which seems to resonate and is acting as a sound body.

[@gregdavidd]

@@quadmovr Hmmm maybe somebody should remove canopy and ducts and see how it sounds :)

[@lalilaloe]

@@quadmovr Indeed, if you remove the shell should be even more quiet. At least this was true for my 3 inch cinewhoop (8 blade)

[@dogswhistlesharam9029]

Can you tell me the thread size and length of the screws to mount the HQ props? I don’t want to trash my motors and the stock screws are too short? ..🤔🤔🤔🤔

[@skairkrow9800]

some say the 4 blade props are quieter than the 5 blade props. great video, nice way to show the comparison.

[@JohanvanBreugel]

Crazy noise! Thanks for comparing.

[@orlandojam8]

6 blade props sound like an alien ship 😂

[@zackmorrison470]

The difference in pitch is interesting. Is there an arrangement that would shift the pitch outside the range of human hearing?

[@quadmovr]

its due to the increased number of blades. if you use way more blades, this frequency can be brought outside the human hearing. theres experiments studying this.

[@5tarman724]

You really want dogs chasing your drone 😂

[@armands672]

No, dogs will be super annoyed by high pitch sound... they will run away from it 😂

[@AlexanderGee]

Generally less blades would be the better idea for less noise. Would be interested to see if you can get it flying with some beefy 2 blade props

[@jkenny1]

He's basically proven the opposite in other videos.

[@hellohogo]

the unreleased dji Flip has 2 blade props. it's about the size of a mini 4 pro

[@ah-64apache84]

they all sound annoying tbh. whoops are just loud

[@ergonomiczero2228]

Should have named this the “pesky mosquito”

[@reyzuna]

Just to remind you all that the DJI Neo was Designed by DJI Engineers to be Noisy. The Reason for this is that it had a Purpose.. The Neo is so Tiny it is Prone to Bird Attack, The loud noise will keep it from Birds and scare them away because of it's noisy sound. Second you will easily notice if your drone is closer or far from you because of its noise, so before you go on wanting to lessen its noise, consider the cons first before replacing its props.

[@ShickDaft]

I agree the follow mode would definitely benefit from the louder noise

[@xbgwright]

very thorough. thanks!

[@ergonomiczero2228]

Wonder how it sounds with bumper guards?

[@samradion]

Interesting that it looks noticeably less stable with the 6 blades - was it windier when that section was filmed?

[@raymondchan3587]

I can installed the 6 blade prop wjthout an adapter, just a few small tweaks on the prop.

[@msanterre]

8 prop blade next

[@armands672]

I second that... maybe 8 blade will push the pitch out of sensitive range of human hearing

[@CRIMSONTYPHOON_YT]

imo i think the 5 blade sounded better, in the comparison the 3" was loud n lower pitch, 5" normal n low pitch and 6" was quiter but higher pitch, 5 inch made it sound like avata2 but 6 inch like avata1

[@innerfire369]

It is possible to buy them from anywhere?

[@MikevomMars]

The only thing that changes is the pitch.

[@philipph80]

these 3 can make a theme song. 2:21

[@DetectDigSmile]

Very cool video

[@cihan9118]

What i hear? Do- re-miii

[@armands672]

Same thought as well. We can now make song with dji neos

[@eddaardwolf]

I'd do a two blade prop, I prefer lower frequency noise.

[@armands672]

Yes, second that too

[@cheekyoscar1353]

Now tell me how long the battery is last between the two .

[@weerobot]

2 blade?

[@MindRiderFPV]

Yep tried the same with my PT35.

[@dougal6569]

For nuisance to people, what matters is the perception of noise rather than any objective measure of sound energy. Now, that perception is actually going to have large individual variation. One physical (rather than personal) factor is age-related hearing loss. These high frequencies will have different audibility to grandparents and grandchildren. And among KZbin viewers, the sound they get will vary greatly - think of the difference between a phone’s internal speaker and some high end headphones! We have to assume quite a lot about the recording conditions and the microphone’s frequency response. So, thanks for an interesting and thought-provoking, if not definitive, video

[@TheMatjebon83]

thanks buddy 👍🏻

[@keithcress1335]

Really nice comparison! Still didn't really like the irritation level provided by all of them.

[@neo_flight]

6 blades is good!

[@spyrosballas1735]

It is doubtful that these propellers can damage the motors and reduce their lifespan.

[@dstepsfpv]

Lets Change the eletrônics for a cf frame! 🔥💪😜

[@josh12823]

gemfan 4 blades still the best

[@mahsiseua]

all sounds loud to me, just different frequency. maybe next video try to measure their dB

[@quadmovr]

the perceived volume of the 6 blade is higher because of the higher frequency but actually the measured volume (dB) is quite a bit lower compared to the 3 and 5 blade.

[@jessemellon6258]

Yeah . . Still sounds horrible unfortunately . . Was excited lol

[@kevinsmall5232]

The 5 blade seemed faster.

[@FPV_OUTDOR]

3 blade 👍👍👍

[@tewkewl]

Volume is the same. The pitch is higher.

[@quadmovr]

measured volume of the 6 blade is quite a bit lower but due to the higher pitch its perceived as the same or even higher volume.

[@noigala]

Original design is better in my ears 😃

[@Sasha315]

Need less blades, not more

[@rogersmith8480]

👍💯👍💯👍💯👍💯👍💯👍!!!!

[@hoebeng1]

It's worse than the stock props

[@einerus]

Too bad there's no dB measure.

[@relaxvideo3d]

next time without props :)

[@Droneaway-72]

To many mugs in drones at the mo Give it a couple months after Xmas most of them will have there drones covered in stick tape and bright pink props . Think most new dronies been watching blue Peter it’s pathetic

[@pitufolaiguana]

You can actually compose a song with the drone... You have DO, RE and MI already 😂

[@armands672]

He just need to find 1 - 8 blade variation to make 1 octave range

[@whatelsewouldyoudo]

no difference. thanks for sharing.

[@IAmIndraTheGod]

All are annoying

[@adeharris4457]

You can't evdn share the stl without charging ppl 👎 & btw it does not take years of practice to fly a dji drone lmao

[@quadmovr]

you are upset of someone saving you time and work? just do it yourself and dont pay a cent for anything. you are right, the last paragraph of the video description does not fit in this case. as i usually post videos of non rtf drones, its in the video description of new uploads by default. changed it.

[@SUBOSVK]

Stock 🫠

[@tartarosnemesis6227]

We just need props with a couple more baldes, so the frequency becomes so high that nobody can hear it anymore. 🫡
