What height does the Platinum's noise become invisible?

[RumpelSluutskin]

i know for the pro's higher pitch tone and volume it is around 400-600 feet.

the platinum has a much different sound without the high pitch ring to it at all, so does anyone know with certainty at what height people will no longer hear it?

ive looked everywhere for this info and the only answer is for the pro not the platinum

thanks!

I can't hear my Pro past 200' with the Platinum blades on.

I can't hear my Pro past 200' with the Platinum blades on.

so this would likely mean 150 for the platinum as only altering the blades while maintaining the pro does not change the motor which still produces a higher tone compared to the platinum. thanks for the reply, anyone with a platinum have any confirmation?

Depends on the winds of course, but at about 150 ft. it is very hard to hear...

how about 100 feet? obvious?

 

[melmartin]

That's pretty subjective... I can hear it but it is not jarring or intrusive...

 

[gjmphoto]

What? Oh, sorry. About 200' for me as well. It's down to 150 or so when I can actually locate it by sound.

 

[RumpelSluutskin]

thanks so much guys!

this must be the quietest commercial drone available then. do any of you paint it sky blue to go incognito?

You all are forgetting one very obvious factor in this. It depends on your speed. It the drone is angled in the air, going 35 mph in sport mode, you will likely hear it at those heights. If not in sport mode and just cruising, then quieter.

Yes, it is the quietest just hovering.

 

[melmartin]

Yes, my estimates were based on hovering..

Or you could just play loud music, and the sunbathers and nudists wont notice you flying over them!

I don’t think it ever gets invisible. At 400 feet over head I can hear it. But it’s not obnoxiously loud like a P4.

At about 500 out and 200 up it’s very hard to hear. Much quieter than either Spark or P4. I can hear the Spark way out as it’s props have quite a high pitched whine.

About 150 ft for me as well.

 

[gjmphoto]

In going out on a limb here...but it probably depends more on how old you are...the older I get the better my hearing used to be!

 

[hughdwaller]

Depends on the background noise. I've flown over a little creed and can't hear it from 40 ft. but people above on the creek bank can hear it 200ft away. All depends on the ambient noise, or wind or ...

 

[genesimmons]

when assending or decending fully i can hear my mav from a long ways away, i have my assend and decend modded though but not to the max it showed on the vid, the stock is 10 the vid said change to 20 i am at 15. its quite loud assending and i can hear lots of wind noise decending fully as well

 

[RobH2]

For me it starts to disappear at about 300'. At 400, if there isn't any ambient or wind, I can still make it out, but just barely, and I'm 60. Don't know about any higher as I don't exceed the Part-107 limit.

That all depends on how good you’re hearing is.
