Helicopter Sounds

Glad I didn’t hear a cough as I listened…

“Scientists made it easier to hear by isolating the 84 hertz helicopter blade sound......”

Really?? 

[Forty Rod SASS 3935]

As great as that is the sound will never replace the wupwwupwupwupwupwupwup of a Huey coming to take you out a bad place.

 

Someone around here flies three to five Hueys about once a month.

[Cold Lake Kid, SASS # 51474]

I guess the noise from the rotors is low enough that it doesn't annoy the neighbours!

[Pat Riot]

How would NASA react if all of a sudden there was a shotgun blast and the drone flew into a hundred pieces?

Didn't hear a thing on the playback.  Dead quiet.

Yeah. And I had the volume turned up to 11.

It's subtle and doesn't come on until maybe 25 seconds into the video. 

 

If you have a headset try with that.

 

With the age and life experiences of so many here I suspect that hearing degradation may make it very,  very difficult for some to hear.

[Rye Miles #13621]

Couldn’t hear a thing either and my hearing is great! The video was cool though!

[Colorado Coffinmaker]

 

WHAT????

[Subdeacon Joe]

Try from this link: https://mars.nasa.gov/news/8941/nasas-perseverance-captures-video-audio-of-fourth-ingenuity-flight/

It sounds like the static hum of an old vacuum tube radio warming up.

[Rye Miles #13621]

I heard it loud and clear on my I-Mac!! Cool!

 

Couldn't hear it on my phone though.

[Sedalia Dave]

No sound on phone or tablet but my PC was loud and clear.

[Subdeacon Joe]

If I listen to it on my Samsung Galaxy S10, outputting through the speakers, I can barely hear it.  If I use the earbuds it is very clear, and if I use my desktop there is no mistaking it.

Nada.  Oh Well.

Try it with earphones of some sort.  Don't expect a standard helicopter thutter, but a hum like static.

Yeah that’s what I did. Just a static sound.....in addition to the normal telephone bells.

The initial wind, then the static hum.  Fortunately it is at a slightly different pitch than my tinnitus so I can hear it with reasonable clarity.  

Every once in a while I wonder what silence would seem like now.

Huh?  What did you say?

Apparently the frequency is somewhere within the range of MY tinnitus.  Of course, I spent major time around LOUD airplanes, not necessarily with correct hearing protection.  I also don't see it as a "Big Deal."
