Very cool video. That noise is actually what's called "mains hum". It's the noise that happens when large current is passed through a coil, and the expanding and collapsing magnetic field (60 hz) starts vibrating all the metal parts in the motor. Lamination of the coils can help reduce this noise, but it will always be there.
much of the sound you hear with the Intamin LIMs and premier/mack LSMs is VFD noise, the noise on the intamin LSMs is the driving frequency and physical disturbance of air from the fins passing close to the magnets. The only ones where you're hearing true hum from 60hz mains is the premier LIMs which sound like giant microwaves as they lack VFDs and are effectively just connected straight to mains power during launch.
@@mr.z_yt Accelerator coasters can't have LSMs either. They are, by their very definition, hydraulic launch coasters. "Accelerator coaster" is a specific model by Intamin that uses hydraulic launches.

“Reduce”? This sounds the sound is quite nice! Until it hurts your eardrums.
@@CoasterKey I'll give it to you, it does sound pretty badass lol
Not all manufacturers think so though 😂
Actually, there are also a lot of VFD sounds here, which are at a much higher frequency.

0:48 the LIM sound fits perfectly with the theme of the ride
That's Intamin for you.
That’s an LSM; I don’t think accelerator coasters would want to have LIM’s because LSM’s can be used as brakes if there was a rollback.

@@triple7marcred force uses lsm
@@user-rs2qw5oq1x Yes I know, but Red Force is not an accelerator coaster.
My favorites are premiere rides launches and those old Intamin screams 😩🤌
Gerstlauer one🤤
My favorite part: 2:14. That one guy screaming "LSM'S!!!!" made my day.
Lmao, I’m that guy who shouted that!
That sound of the LSM is oddly satisfying
*coasters go whoosh*
2:14 LSMs!!! YEEAAAAH!!!! 🤣
i love that sound
0:39 my fav and 0:54 and at 2:14 THIS CAUGHT ME OFF GAURD WHEN THAT GUY SCREAM LSM!!!!!
I LOVE the Sound of LIM! 0:39 0:54
From premier rides
Same, it has such an industrial sound to it. So intense
steel venom has by far the best LIM launch sound ever.
Ugh the sound Volcano would make was something else man 😩 I miss that coaster so much
Cheetah Hunt is my favourite launch sound
3:09 personal
Oh hey you actually made one
Volcano the blast coaster has the best LIM sound
cheetah hunt is pretty similar
Premiers sounds like high pitch screaming and Intamin’s is just amazing
Ahh first one steel venom at my home park chefs kiss
i swear premiere rides had the best sounding ones, full throttle and wcr best ones
LIM > LSM
I agree
0:46 definitely good to relax to lmao
Hehe…
Not to mention Taron xd
Nothing like taron’s roar
The modern Intamins sound insane
I like the LSM launches the best, like 3:19
The best
California Screamin had an LIM
I like Abyssus sound that how it's squeaking before the launch is funny 🤣🤣
Every Other Coaster Manufacturer’s LSM: nnnnyyyyyeeeeeeeeee
Intamin: Haha LSM go BBBBBBRRRRRRRRRRRRRRRUUUUUUUU
and that why we love them
0:48 Best LIM sound, you can't change my mind
taron better
Looked this up just to see what they’re doing to the top thrill dragster and man idk
1 subscriber before the 400 subs guys! He did it!
lsm sounds like a flashbang just went off
Roller Coaster jumpscare: 0:13
3:19 personal timestamp
Do titan max at space world in japan for a coasters you forgot about
Maaayyyyybe
Stealth, Thorpe Park. *VERY SEXY MAGS*
Do a rides you forgot about video on nightmare at crack axel canyon at great escape
Kinda upset jokers jinx was not on here considering is has one of the most wicked launch sounds lol
Poltergeist is on here though! Same designer/sound and use of LIMs. Flight of Fear as well.
@@PandaBear1316 yes ik but the lauch on jokers jinx is more pronounced
Where is the shred the shewers launch coaster?
Thoosie Asmr
The video you ised for tarons launch is kinda bad, you should have used a offride one, those sound a lot better, and mostly got better quality
you forgot a lot lol
Best LSM sound is this Intamin one for me :D

if you scream on rides I have a personal problem with you
That rules out like 90% of coaster riders lol
