The Secrets Behind 44 Classic Cinema Sound Effects

No, really, the Ringwraiths are actually plastic cups...

The art of sound began in 1927, when Universal employee Jack Foley helped turn the film studio’s "silent” Show Boat into a full-on musical extravaganza. Because microphones could only pick up on dialogue, Foley had to add in the other sounds later. He projected the film onto a screen and recorded the footsteps, the movement, the props – all in one track. He walked with a cane to create the footsteps of three people. He acted out the film, all over again.

As it turned out, Foley gave his name to an industry of post-production sound design, where aural artists “footstep” every character just as Jack did (utilising wardrobes full of shoes). Vegetables are chopped, watermelons are smashed, coconut shells are clacked, cooked chickens are squished, keys are scraped and jangled: all in the service of replicating noises that couldn’t be recorded live, or don’t sound “right”, or creating sounds that don’t exist in the first place. The following are 44 of the most creative examples.

“Foley is an interesting world,” actor Toby Jones mused, coming off his character’s own off-kilter audio post-production experience on Berberian Sound Studio. “The disconnection between the effect you’re trying to generate and what’s causing it is often comical or disproportionate. The artificiality of a film’s production compared to something you’re hoping to show as ultra-real is fascinating...”

In the movie we see foley artists smashing melons, but if you thought the sound effect was achieved by, well, smashing melons, you’d be wrong. “I tried to do something with melons,” says foley supervisor Heikki Kossi, “but it didn’t sound wet enough, so I just used a wet piece of cloth. Then I also wanted to hear some kind of cracking, crashing sound, so I just used a little piece of wood. Cracking that gave the right kind of violent feeling for what they were doing. For the sound of the very sharp knife I used a very good sounding knife that I have in my studio. There were all these layers to make the final sound.”

Raiders Of The Lost Ark (1981)

Effect needed: Rolling boulder

Actual sound: Rolling car without a motor running

"It was rolling a car without a motor, and also one of those big, heavy lawn rollers to make your lawn flat: rolling that down a hill.” Some of the truck sounds in the chase sequences, meanwhile, were augmented with tiger growls.

**Star Wars **(1977)

***Effect needed: ***Blaster pistol

Perhaps going beyond the call of duty, feeling that a studio lash-up wouldn’t quite cut the mustard, he found the specific sound he wanted by climbing a radio mast and pummelling its guide cables.

**Star Wars **(1977)

Effect needed: Lightsaber

Actual sound: Microphone feedback from a tube TV

“I was carrying a microphone across the room,” Ben Burtt explained, “and I passed a television set which was on the floor which was on at the time without the sound turned up, but the microphone passed right behind the picture tube and as it did, it produced an unusual hum. It picked up a transmission from the television set and a signal was induced into its sound reproducing mechanism, and that was a great buzz. So I took that buzz and recorded it and combined it with the projector motor sound and that 50/50 kind of combination of those two sounds became the basic lightsaber tone.”

To get the additional sense of movement as the characters swished and clashed the weapons, Burtt simply played his sound over a loudspeaker. “The humming and the buzzing combined as an endless sound, and then I took another microphone and waved in the air next to that speaker so that it would come close to the speaker and go away and you could whip it by, and what happens when you do that by recording with a moving microphone is you get a Doppler shift: a pitch shift in the sound and therefore you can produce a very authentic facsimile of a moving sound."

With a Wookiee, you might end up with five or six tracks, sometimes, to get the flow of the sentence."

The ambient sound of the wind was simply recorded by sticking a mic at the crack of a door leading outside at George Lucas’ Skywalker Ranch, with an element of a human voice making "whoosh" noises. The sound that accompanies the shot of the Terminator stamping on a human skull is a pistachio nut being ground into a metal plate.

Terminator 2: Judgment Day (1991)

**Effect needed: **Liquid metal morphing

''It doesn't have any bubbles in it. It doesn't gurgle. It doesn't do anything visually except flow like mercury...'' The perfect sound to match the visuals was created by putting a condom over a microphone and dipping it into an evil solution of water, flour, and the furniture cleaner Dust-Off. ''It would make these huge goopy bubbles,'' says Rydstrom, ''and the moment when the bubble is forming, it has this sound similar to a cappuccino maker. I believed it...''

Turns out it sounds like a drinking glass being dropped end-first into a bucket of yogurt. The sound of the T-1000 morphing itself around the prison bars, meanwhile, is dog food being schlupped out of a can. ''A lot of that I would play backward or do something to,'' sound man Gary Rydstrom says, ''but those were the basic elements. What's amazing to me is ... Industrial Light & Magic using millions of dollars of high-tech digital equipment and computers to come up with the visuals, and meanwhile I'm inverting a dog food can.''

Where it needed to sound more conventionally voice-like (in the moments where it's bellowing in rage or pain), there are donkeys and horses in the mix.

Lord Of The Rings (2001-2003)

Effect needed: Ringwraith

***Actual sound: ***Plastic cups

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();Beginning with doctoring the sounds of harbor seals, David Farmer eventually hit on a different tack for the screechy Ringwraiths. “Michael Kamper was working with me,” he recalls. ”He said the seal noise sounded like a plastic cup scraping. So I went to Target, bought a bunch of plastic cups and bowls, and then Harry Cohen and I did a record session in the foley room. So I finished that creature using nothing but the plastic cup scrapes. I used them in the Wraith screams quite a bit. They added a really nice, dry, aggressive raspiness that really finished off the sound. I still use those cup scrapes today.”

Lord Of The Rings (2001-2003)

Effect needed: Shelob

***Actual sound: ***Toy alien head

listen to ‘16 Lord Of The Rings - Shelob’ on audioBoom

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();Although it’s not quite what we hear in the finished film, much of the high-end basis of the horrifying giant spider Shelob’s voice is a plastic toy alien head filled with liquid. “When you’d squeeze it, it had this crazy wet screech,” enthused David Farmer. “I’d actually recorded it years before Rings and had always been looking for a place to use it, but nothing fit. Along came Shelob, so I recorded a lot more of it. Everyone thought it was a real creature, and that it was pissed! It was pretty high-pitched. I was trying to do a creature that had no low end since almost all the others had a lot, but it didn’t give us the threat I’d hoped it would. Peter [Jackson] wanted it to sound more alligator hissy instead. But I miss the character that alien head added.”

Lord Of The Rings (2001-2003)

***Effect needed: ***Orcs

***Actual sound: ***Baby elephant seals

I’d never heard that sound before and knew that would be perfect for the Moria Orcs. The Moria Orcs were the smallest of the orcs, and Peter’s direction for them was “sort of cockroachy”. So we recorded ourselves scrambling around wearing cleats for the movement. But the major signature sound for them was the elephant seal pups.”

Lord Of The Rings (2001-2003)

***Effect needed: ***Uruk-hai

***Actual sound: ***Sea lions and big cats

listen to ‘18 Lord Of The Rings - Uruk-Hai ’ on audioBoom

Hence David Farmer opted for bigger sea mammals in the form of adult sea lions, with tigers and leopards mixed in. “We also recorded ourselves a few times,” he adds, “most all of the sound team, and we peppered in those vocalisations to add variety and a more human reaction. Most of the wetter, slobbery-type stuff is human. Most of the character comes from animal elements, but the human stuff helps stitch it together as humanoid. It really needed to be a combination of animal and human to pull it off.”

**Jurassic Park **(1993)

The unpleasant sound of Martin Ferrero getting eaten is a horse munching a corncob.

Raging Bull (1980)

At base, the punching sounds themselves were achieved with sides of beef. But layered with that are manipulated slabs of music, roaring animals, engine noises and flashbulbs.

Every six-gun and rifle sounded the same. Peckinpah threw a fit, insisting that new gunshots be recorded so that each gun in the picture had its own individual sound. By the time they were finished more than a hundred different gunshots were used on the effects track. “To mesh all of those onto one track and still bring out those individual sounds was a son of a bitch, but it happened, you’ll hear it,” said [editor] Lou Lombardo. “You know when William Holden fires ‘cause that forty-five barks, and you know when Strother Martin fires that thirty-ought-six. Sam raised hell over that effects track, but he got them to bring it up to a level of quality that won them awards.”

Hence sound artist Joan Rowe “walked through some stores and listened to the movement of packaged liver in a flat container. It had a cheery sound!” Revisiting the store for fresh supplies every couple of days, she became known as “the lady who listens to the liver!” Rowe also recorded the sound of jelly in a wet towel and popcorn in a bag. All three sounds are in the mix every time E.T. moves.

For me, the scene plays like a symphony of little sounds.

We made Reedman with buzzing magnets, surging air rifle BB pellets, rolling metal ball-bearings, “chiming” steel washers dangling from strings, and a bunch of zippery sounds we constructed out of thousands of little metal clinks.” The gurgling noises Reedman makes were voiced by Reno Wilson, and his shrieks were voice-acting legend Frank Welker.

The algae-based jelly swells in cold water, absorbing up to 20 times its own weight. “I was swimming about in the stuff all day,” said Joseph. “It was very gloopy.

But, for Joseph’s money, there was no substitute for a green coconut. “The outside is fibrous,” he explained, “so it cuts like skin. And the hard shell sounds like bone.

We've done it all, and as a result of this project our 'punch' library has become quite extensive. When you hear the punches in a film like Rocky they usually just use one punch over and over again; it's very muddy and dark, and kind of boxy sounding.

But that’s not all there is to those moments. “For the claw sound, essentially there were two main elements I was working on,” explained sound designer Craig Berkey. “One was the metallic blade sound, as it goes in or out. The other was the actual physical sound of something going through flesh and retracting." The latter is a combination of chicken and turkey carcasses being ripped and nuts being cracked.

**X2 **(2003)

***Effect needed: ***"BAMF!"

***Actual sound: ***Dog food, compressed air

The sound created included the sucking of dog food from a can; camera flash bulbs; and the release of compressed air. The air sounds were played forwards or backwards depending on whether Nightcrawler was arriving or departing.

Spider-Man (2002)

**Effect needed: **"Thwip!"

**Actual sound: **Fishing line, shaving cream

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();Spider-Man’s web-spinning was achieved with various fishing lines, including one strung between two posts and strummed, and the swish of the fly-fishing variety. There’s also the noise of magnetic film being tightened on a spindle, and a bit of compressed air being blasted. The wetness – Raimi’s Spidey spun organic webs, remember – comes from shaving foam.

Predator (1987)

***Effect needed: ***Predator moving

***Actual sound: ***Chamois leather

Another was hand lotion on my hands. A third was a wet leather purse. A fourth track was some mouth noises (the voice acting and clicking is credited to Transformers’ Peter Cullen). We called it ‘Predabody’. There was also ‘Predaface’, ‘Predahands’ and ‘Predafeet’!”

Speed (1994)

Effect needed: Elevator

***Actual sound: ***Magnetic film rewinder

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();The sound of an elevator could easily have been called up from an effects library, but Joan Rowe was slightly more obsessive. “She found a magnetic film rewinder that had a glitch in its mechanical action,” recounts her colleague Vanessa Theme Ament. “When she wound it backward it made ‘a good sound’, and she mounted it on a table on the stage. Then she put an editor’s metal trim bin upside-down on the table for echo. She wound the rewinder forward for the elevator going up, and backward for the elevator gears grinding. Then she banged wires against the trim bin to sweeten the sound for the gears.”

**Godzilla **(1954)

Effect needed: Roar

***Actual sound: ***Double bass

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();Ishiro Honda’s sound team played around with various recordings of animals for Gojira’s ominous bellow, but found nothing quite fit the bill. The sound they ended up with was the strings of a double bass being rubbed with a leather glove coated in pine tar resin. Intriguingly, the team behind Gareth Edwards’ most recent version have declined to reveal how the latest roar was created.

Tarzan (1932-)

Effect needed: Jungle call

***Actual sound: ***Pick a story…

listen to ‘41 Tarzan - Tarzan's Yell ’ on audioBoom

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();Much debate exists around the mystery of how Johnny Weissmuller’s trademark ‘Ahhhhh-ee-ahh-ee-ahhhhh!’ Tarzan yell was created. The official line from MGM in 1939 was that it included Weissmuller’s own voice; a hyena’s howl played backwards; a note sung by a soprano being played back at various speeds; a dog’s growl; and the G-string of a violin. This is almost certainly bollocks. Elsewhere, opera singer Lloyd Thomas Leech claimed that he had performed it himself and been paid a thousand dollars for the continued use of the recording. That might be true, although it’s likely the sound was further worked on in the studio: it’s actually completely palindromic, sounding exactly the same when played backwards as forwards. Weissmuller, as part of his self-mythologising, always claimed it was simply his own voice. That’s nonsense too, although it’s certainly true that he learned to do a fairly close approximation of the call for later public appearances.

Tron (1982)

***Effect needed: ***Lightcycles

Actual sound: Video game tones

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();The lightcycles rip along the grid to a smorgasbord of mashed-up electronic Atari video game tones. That’s augmented, naturally enough, with actual motorbike engine noises, but there are also synthesizers and a buzz saw in the mix.

Back To The Future (1985)

***Effect needed: ***DeLorean doors

Actual sound: Car window regulator

listen to ‘43 Back To The Future - DeLorean Doors ’ on audioBoom

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();Apparently the gull-wing doors on a DeLorean don’t sound enough like the gull-wing doors on a DeLorean. The sound of their lifting and descending is a car window regulator: the mechanism that makes the electric windows in your motor go up and down smoothly. The same noise is used at the start of the film for Doc Brown’s electric dog feeder.

A Nightmare On Elm Street (1984)

Effect needed: Freddy’s glove

Actual sound: Much bigger knives

listen to ‘44 Nightmare On Elm Street - Freddy's Gloves ’ on audioBoom

(function() { var po = document.createElement("script"); po.type = "text/javascript"; po.async = true; po.src = "https://d15mj6e6qmt1na.cloudfront.net/cdn/embed.js"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(po, s); })();Freddy Krueger’s weapon of choice is, of course, that knife-fingered glove. That means you need two sounds in your Freddy foley kit: leather and blades. For the former, a belt was bent and creaked and generally manipulated. For the sharper end, the effect was emphasised by sliding a surgical steel blade along a machete.
