noise in freefall

Recommended Posts

I can't speak to the exact decibles in freefall but I can tell you not to be surprised that, no matter which audible that you choose, you probably will not hear it on the first couple of jumps that you use it. It's almost as if you must tune yourself into it, like to teach yourself to listen for it. At least, that's what I found. Good Luck.

I totally understand your concern and I am just representative of my own experience and the experience of coaching my wife through AFF and 160 jumps, but we both experienced the same thing. It's the sensory overload thing. If you condition yourself to pull at a visual stimuli, (altimeter) we found that you must actively listen for the audible in the first few jumps to even hear it. After you hear it a couple of times, you begin to associate it with "time to track away (or pull)" and soon it becomes automatic. But you gotta remember that audibles, like visual altimeters, are not infalible. You also need to condition yourself to timing and the 'ground picture" to make sure that you pull on time.

That's just my opinion. Can anyone else help us here?

you are 100% right with that reply, and comes with
numbers, you have the words of good wisdom and
thats what I enjoy in this forum. I have been told that an audible for a low time jumper is not a good thing but the majority says it's a great BACKUP.

If you're wearing a closed face helmet, you'd have to be REALLY hard of hearing to not hear an audible.
My first few jumps with one, I found it quite startling.

Stay safe,

If you're gonna' be stupid, well, then you're most likely stupid.

Do you have a motorcycle? Does it go fast? B|

I have gotten so used to wind noise commuting at 75 mph on the freeway on a no-windshield motorcycle that freefall seems silent to me. Something about the russling noise makes my brain tune it out. Under canopy the flapping slider is loud, though - go figure.

No, that's no direct use to you in deciding what audible you want, but it's a hint: freefall is about as loud as 120mph wind noise on a motorcycle. Maybe a little quieter because there's no engine or sirens.

This depends greatly on what type of helmet you have (protec vs. full face vs freefly) and how tightly it fits over your head. You might start with wind noise on the order of 90-100dB, a protec might give you a few dB of attenuation, where as a tight fitting full-face or freefly helmet could give you upwards of 30dB of attenuation. At that noise level, an audible should definitely be able to "wake you up"

Try asking around your dropzone if you can jump someone's to test it out before you buy one.

Nullified,
Now that you mention it, I was jumping a frap hat when I bought my first audible and since I switched to a full face I have had no problem hearing it. I'm glad you brought that up, not only am I hard of hearing but I can't remember s*#t either.:)

I can't remember shit either, but that's another story. ;)

However, I own both a Z1 and a mindwarp. The mindwarp is the older style with external pocket. I've never really heard my audible well enough...like stated above, you have to be listening for it.

On the otherhand, when I started jumping my Z1 I could hear it no problem. I loved it. As of late I can't hear it for shit. I've even tried adjusting it inside the helmet to no avail. Maybe I'm loosing my hearing? Someone mentioned I might be deaf to high pitched tones, not so if I can hear it on the ground. Which I can, so what the hell? :P

Might depend on the bike. My fairing tends to spill wind towards my head, and the front of the bike definitely disturbs airflow before it gets to me. In freefall it's cleaner, but my open student helmet is pretty noisy.
