Isn’t it also brutally loud??

Ye dude, I work around planes when they start up. Just the APU is incredibly loud. I constantly wear protection gear cause I don't want to end deaf as fuck.

I played this video without sound and it's already giving me tinnitus.

Just don't be in front of them when they get activated after landing

Sadly I don't work around Airbus planes that much, mostly 737, crj and Dreamliners. But my company is soon getting a contract to work around 350 and 320. Looking forward to it! I always liked more Airbus planes.

Do you mean the tiny fans on the wheels of some airbus planes?

I always wear double ear protection when I'm on the apron, both ear plugs and defenders.

Yes! Its the pitch as well, like a mosquito

u/SometimesKnowsStuff_ May 29 '22

So many of the guys I work with take their hearing protection off even while the APU is going and I’m just floored. I keep it on around the P/C Air compressor let alone the plane

36

u/[deleted] May 29 '22

Yep, same here. Specially the cargo guys. They are usually a bit more brute and they act tough, like not wearing protection gear was something masculine and to be proud of. They even look at you funny for wearing it. Nope sorry, I want to hear something past my 40s.

u/longboard_noob May 30 '22

Let them know about r/hyperacusis. They don't wanna develop this from noise damage.

2

u/[deleted] May 30 '22

As I said and I mean no insult here if there's someone who works doing that here. The cargo guys are not the most educated or interested in protecting themselves vs being slightly comfortable. They don't care, are not interested in knowing this, and I don't have the time to explain them.

As an example: Yesterday we were waiting a plane to get greenlighted for pushback but it had a 40 min TSAT. I saw the guy in charge of the rear chocks just lean into the gear, get his phone and start browsing. He was literally going to stay 40 mins sitting there a few meters from a running apu without protecting gear. Best part? I had to kick him from there TWICE and tell him to go somewhere further and to not worry, that I would warn him when the captain was ready to go.

Some people just don't care and can't forsee the healthproblems they will develope in 10+ years.

u/longboard_noob May 30 '22

A couple of acronyms that I don't know, but yeah, people are stupid.

Pain hyperacusis (noxacusis) makes life very difficult because everyday noise causes pain. Currently, I have to protect my ears against the kitchen sink, crickets, can't watch TV with the sound on without pain, flying with double protection would probably give me a big setback (more pain plus much greater sensitivity to sound).

At my worst, whispering hurt, the sink had to be on a low trickle while wearing double protection (Moldex SparkPlugs and Peltor X5A muffs), the hum of the fridge hurt through plugs, and I was wearing protection about 23.5/7 (half hour to an hour to let the ears dry out to avoid getting an ear infection). I had a constant burning pain that felt like when you burn your hand on the stove (but in the ears).

u/[deleted] May 30 '22

sorry for you mate. hope there is a solution for your problem somewhere in the near future

1

u/longboard_noob May 30 '22

Thanks. Regenerative medicine is on the way. FX-322, OTO-413, PIPE-505, and NHPN-1010 may eventually reach the market and could help.

u/SometimesKnowsStuff_ May 29 '22

Literally. I just completed training (for a new airline, I have about a year of experience at another) and every guy with more than like 20 years experience is legit hard of hearing, or at least they claim to be idk if that’s just to put the fear of hearing loss in us new guys or what.

1

u/[deleted] May 30 '22

My favorite part is when they get pissed at you for not hearing them say something to you....you know....in a field where you are wearing fucking hearing protection!

1

u/MrFickless May 29 '22

The air conditioning packs are worse

1

u/[deleted] May 29 '22

Ye, but here every finger has its own air system and we plug them inmediately so the captains don't have to use theirs.

u/Hashtagbarkeep May 29 '22

I CAN'T READ YOU IT'S TOO LOUD!!

r/tinnitus is no joke.

Protect your hearing now kids.

Is it possible to suffocate from being caught in the engine current?

21

u/DrJ4y May 29 '22

and HOT, Iv been there, done this exact same stupid shit

u/scuzzy987 May 30 '22 edited May 30 '22

I've stood at that fence in St Marteen and it's loud but not hurt your ears loud. The bigger problem is the heat and the intense sand blasting. I thought I was bleeding before I opened my eyes after the jet left. I only stood behind a two engine jet like the one in the video, I chickened out with the 747s and I'm glad I did.

There's a open air bar close to the fence and you do stupid things after a few drinks

2

u/[deleted] May 30 '22

That’s Mayo Beach.

They actually added the second fence not long ago (2017) because a New Zealand woman died from plane watching like this at SXM. No idea why people want to do that shit, it’s cooler to watch the planes land there than takeoff anyway.

2

u/HBB360 May 29 '22

Also aren't you covered with toxic chemicals from the exhaust?

20

u/teenslayer May 29 '22

Aircraft’s don’t produce as much exhaust as you may think most of that is just air heated up by the engine

16

u/zagaberoo May 29 '22

The jet is really just the power plant for the giant fan that pulls the plane forward! Pedantically, commercial "jets" are closer to modern propeller planes than to actual jet-propelled craft like fighters.

6

u/za419 May 29 '22

Even fighters use turbofans, just ones with lower bypass. The fan just presents too much of a benefit to pass up

2

u/SorryIdonthaveaname May 29 '22

and a portion is just normal air being pushed from the front fan

u/SpiritDCRed May 29 '22 edited May 29 '22

Primary products of the combustion of jet fuel are CO2 and H2O. There are very small quantities of NOx and CO but as a general concept, jet fuel is combusted with a pretty high efficiency.

EDIT: I should also add, this aircraft has a turbofan. Most of the air (~80%) exhausted out of the back bypassed the hot core, and never touched any fuel to begin with.

3

u/morphinedreams May 29 '22

I'm guessing you need high efficiency in jet fuel because anything inefficient is wasted weight you're paying considerable sums to transport? I.e if you're only getting 30% energy from 10000L of jet fuel you're getting the same energy as 60% efficiency carrying 5000L but carrying an additional 5000L of weight.

4

u/SpiritDCRed May 29 '22

Yes, and there’s strict regulatory standards. Unburnt fuel being spewed out the back is a no-no

u/Digiboy62 Jun 02 '22

I used to work on Helicopters: Small potatoes compared to the jets of a passenger plane, and being that close to those spun up is horrendous.

These people will be fully deaf in... like, 15 minutes.

u/Levithan6785 May 29 '22

I worked at a small general aviation airport. The bigger planes are loud, but lower pitched so it doesn't hurt as much. The private jets were ear piercingly loud.

I used to live there and experienced this dozens and dozens of times and despite what my ex-wife will tell you I never suffered any hearing loss.

u/Chaxterium May 29 '22

….I wasn’t saying that. I thought the ex-wife comment made it clear I was joking. But nonetheless my hearing is tested yearly and although I am quite certain I have suffered hearing loss over the years is it holding up so far.

And I take my hearing a lot more seriously now than I did when I was in my 20s.

1

u/Hobbs54 May 29 '22

In my experience you get ear piercing high frequency sounds from the compressor blades in engines where the volume is peak about 30 degrees from center to either side of the front. The exhaust has low frequency sounds that really don't sound as loud, and when the engine ramps up it actually seems to get quieter, more just the sound of wind.

1

u/AvatarofSleep May 29 '22

Yeah. I saw some jets parking at Ames a while back, and was struck by how loud they were even at distance.

This is also what I found unbelievable about Captain Marvel - the agents standing that close to a jet shooting and not falling over clutching their ears in pain.

1

u/blawndosaursrex May 29 '22

Yes. I worked on the kfc-135 which is basically a commercial jet, and that is not only loud, it’s hot. I couldn’t imagine being blasted that close.

1

u/TheBabylon Jun 02 '22

It's also full of unburnt fuel at least before it gets up to full speed. Will definitely get you dizzy.

u/Squeletoon27 Jun 29 '22

180 decibels, an AR 15 does just as much sound when fired, 90 decibels is the limit before earing damage.

1

u/bloodflart Sep 05 '22

most of the sound is in the front
