Forty Rod SASS 3935 8,424 Posted May 8 Share Posted May 8 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. 7 1 Quote Link to post Share on other sites
Cold Lake Kid, SASS # 51474 9,503 Posted May 8 Share Posted May 8 I guess the noise from the rotors is low enough that it doesn't annoy the neighbours! 5 Quote Link to post Share on other sites

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.

Subdeacon Joe 29,394 Posted May 9 Author Share Posted May 9 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. Quote Link to post Share on other sites
Rye Miles #13621 7,381 Posted May 9 Share Posted May 9 I heard it loud and clear on my I-Mac!! Cool! Couldn't hear it on my phone though. 1 Quote Link to post Share on other sites

Subdeacon Joe 29,394 Posted May 9 Author Share Posted May 9 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. Quote Link to post Share on other sites

Yeah that’s what I did. Just a static sound.....in addition to the normal telephone bells. 1 Quote Link to post Share on other sites

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. 2 Quote Link to post Share on other sites

Colorado Coffinmaker 3,759 Posted May 10 Share Posted May 10 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." Quote Link to post Share on other sites
