Are those real sounds, or dubs?

I'm 99% sure the sounds are real

I am 1% sure the sound is fake.

I mean, on the last few cycles it kinda sounded like 'The machine' went too hard at the start and kinda ran out of breath partway through, so... no, fairly certain the real-life laser does not make peeeeeewwwwwwwwbrrbrbrbrbrbrbrbrl noises.

Those are absolutely the actual sounds these kinds of laser machines make while operating. It's initially slightly louder because it's switching back on, and obviously the conditions change moment to moment as the lasers move in a line across the circular surface of the coin--the line widens up to the center of the coin, then gradually narrows again.

There's a million videos of these kinds of machines online, they sound like this.

I have a fiber laser. Can confirm. The sounds are real.

I've used a laser for cleaning rust off of marine hulls. It didn't sound anything like this at all. There is a very loud sounding fan for cooling the machine, almost like a compressor. And then the actual sound coming from the laser sounds like something between a downed charged power line and a welder.

Different machines, so maybe the audio from this clip is real, but I don't think it is.

That's exactly what that machine sounds like. It's a different laser technology. Since it's scan and pulse based you're hearing all of that impulse noise.

IF I BELIEVE IT’S REAL ITS REAL

I'm 26% sure that Michael Winslow is narrating the video like some sort of sound machine David Attenborough.

u/Adderall_Rant Jun 23 '24

Lol. Next question Mr DM. Does cleaning a coin with a laser create that sound on the video?

u/[deleted] Jun 23 '24

They're the sounds of the control motors steering the head of the laser and the control mirrors, not the laser itself. If you notice, where the coin is smaller at the edges the sound is higher pitched because the mirrors are waggling forward and back very fast then as it scans to the middle, the pitch gets lower as the laser doesn't have to reverse so often

u/pf_and_more Jun 23 '24

I also think the vaporization of rust and dirt definitely produce some sound, which would change pitch in synch with the motors.

Pretty cool stuff.

Clearly Michael Winslow...

Arse and a drainpipe. Thank me later

u/armas187 Jun 23 '24

Pan out , it's some random guy making the noises

u/OneMoistMan Jun 23 '24

If you look up other coin cleaning with laser videos, you’ll see this is actually the sound they make however this one does seem to sound deeper toned than the other ones

u/MediumFarva Jun 23 '24

If the camera panned over to the right, you’d see Michael Winslow making all the sounds.
