How To Use Explosion Sound Effects in Film | Royalty-Free Sounds
explosion sounds

Explosion sound effects are an emblem of ultimate power, from the creative force of the big bang to the world-erasing nuclear bomb. When scaled down to a kernel of corn in the microwave, we use separate words like pop or bang instead. Applied to storytelling, explosions mark a moment of climax and transformation. In this article we'll offer several examples of explosion sounds that occur in film.

We've hand-picked a collection of royalty free explosion sound effects from the Audio Design Desk collection.

Cinematic trailers: Non-diegetic explosions and impacts

Before we get into diegetic sounds that take place within the context of a movie scene, let’s begin with the explosions used in cinematic trailers. It’s common to hear these sounds used in big-budget film trailers.

In the Transformer (2023) trailer above, we can hear massive impact sounds right away. The sounds may be produced by a resonant timpani drum but their design is explosive nevertheless.

Destructive explosion sound effects in film

In a movie scene, explosion sounds often mark moments of chaos and destruction. The quality of explosion sound effects have improved tremendously over the years. We’ll start by exploring classic sounds and then move on to modern examples.

Star Wars and Ben Burtt – The ultimate space explosion

It’s endearing to look back at iconic scenes from the 1977 Star Wars film Empire Strikes back, knowing that these were state of the art special effects at the time. During the Star Wars sound design documentary below, Ben Burtt describes his techniques in detail. We’ve timestamped the section where he explains some of the secrets behind some of their sound design.

 

“When the Probot blows up, I remember one of the principle elements in that explosion is a big sheet of plywood which we snapped out and back of the building in the parking lot and added it in on top of the explosion itself he dubbed it the wood crack attack explosion … I went to White Sands Missile Range to record missiles and rockets taking off and impacting and air-to-air interceptions. I went to many military bases and recorded tanks shooting and artillery always in a quest which I call the search for the ultimate explosion”

Taken out of context, the Death Star looks like a toy model. The low-frequency, colossal explosion lacks some of the acoustic depth that we’ve come to expect from similar scenes today. John Williams’ timeless film score makes up for it with its complexity and emotional depth. The sound design leading up to the explosion, from the ship powering down to the Doppler effect of the X-wings escaping, evoking a feeling of supreme accomplishment in the war of good against evil.

Die hard, Tenet – Chain reactions and exploding buildings

A single profound explosion like the Death Star provides plenty of space for gradual decay. But in scenes where a chain reaction has been triggered, like this classic moment from Die Hard (1988), the compounded explosion sound effects need special preparation.

This building explosion scene raised the bar for action movies and left a lasting impact on cinema. Bruce Willis, playing the hero John McClane, pushes a bundle of explosives down an elevator shaft in an effort to save a group of hostages.

There’s a moment of profound silence as the explosives drop, followed by nearly 20 seconds of rolling fires, low-frequency booms, and building materials shattering as it leaves a trail of destruction in its wake.

Thirty years later, the Tenet (2020) offered a fresh, mind-bending take on the typical sound design for exploding buildings. It follows a former CIA agent who manipulates the flow of time to prevent attacks that will take place in the future. The scene below highlights a moment where a building explodes in reverse, followed immediately by re-destruction.

This is one of the few moments in cinema where you’ll find a reversed explosion sound effect woven into a plot. Rattling debris accompany the reconstruction of the buildings to add to the build up. By pairing these reversed sounds with actual explosions, the war film achieves a similar rise-and-release effect for the audience.

Mad Max – Exploding cars and the sound of flying debris

The sound design for exploding cars resembles those used with exploding buildings. In the scene below from Mad Max (2015), a series of oil tankers explode in the desert.

Alongside some of the explosive booms, the audience hears whizzing sounds of shrapnel flying through the air like bullets. This adds to the felt sense of risk for the main characters, who could be hit at any moment by a small piece of metal.

Toy Story – Dynamite and firecrackers

Smaller scale explosions, like dynamite and firecrackers, can still pack a punch. In this scene below from Toy Story (1995), the problem child Sid attaches a small stick of dynamite to his toy soldier and blows it up in his back yard.

Notice how the explosions sound effect is followed by the playful clop-clop sound of wooden blocks. This immediately lightens the emotional impact of the sound for the kids in the audience, making it feel a little less scary.

Scanners, Mars Attacks, Monty Python, Jaws – Exploding body parts

Exploding body parts are gruesome and might not be appropriate for all ages. That being said, their sound design differs considerably from the sonic texture of buildings and cars. You’re likely to hear squishing and liquid, representing the biological matter splattering across the environment.

The video above comes from Scanners (1981) may be the most iconic exploding head in film history. Early in the film, a character’s head explodes under the influence of psychic powers. A high pitched frequency leads up to the pivotal moment, symbolizing the pressure building within the character’s skulls and mirroring an actual experience called tinnitus, or ringing in one’s ears.

Sometimes an exploding head can be funny, like this scene from Mars Attacks (1996) when an innocent grandmother accidentally discovers how to defeat the evil invaders by playing country music. The foley for this scene is unique because the exploding brains are contained within glass. As the aliens screech and top on their helmets, we watch their brains grow like a balloon before exploding within the container. The acoustic decay is cut off abruptly because the glass stays in tact.

Stomachs are another body part that have been known to explode, particularly in comedies. The video above is from Monty Python’s Meaning of Life (1983). A grotesque man eats until his stomach explodes. Notice the wet sound of his innards landing across different areas of the room. These are classic “biological” sounds associated with exploding bodies.

Filmmakers have been known to experiment with exploding animals as well. In Jaws (1975), an air compression tank is stuffed into the shark’s mouth while it’s trying to sink the ship. As it circles the boat, a series of gun shots ring out before hitting the mark and causing the shark to explode. We hear a standard boom followed by the shark guts splashing out around the surface of the ocean.

The Abyss – Underwater explosion sounds

Sounds travel through air differently than they do underwater. It follows that underwater explosions would feature low-frequency, resonant booms due to the water’s density. Shockwaves from the explosion can also be visualized as rapidly expanding rings or bubbles, adding to the dramatic effect. Sound designers often use a combination of real underwater recordings and synthesized sounds to create the desired effect for cinema.

When a submarine sinks in The Abyss (1989), we see and hear an initial cracking and scraping of the glass case as it buckles under atmospheric pressure. These sounds are coupled with a haunting layer of dissonant strings in the soundtrack. We hear the submariner yell as he recognizes that he’s out of luck. There’s a massive explosion but the sound lasts only two seconds before it dissipates in the water and a column of bubbling sounds rise to the surface.

Life-generating explosion sound effects in movies

Explosions are not always limited to destructive purposes. We find similar effects used to represent the creation of the universe and other life-generating moments.

Tree of Life, The Fountain – Explosions at the center of the galaxy

The scene above, from Terrence Malick’s film Tree of Life (2011), features a perpetual rumbling explosion that emanates from the center of the galaxy. Paired with a bold and operatic melody, this sound effect has an intense and profound impact on how the audience perceives the story.

A reverse-explosion effect is used in The Fountain (2006) to convey a climactic moment of cosmic unity. Preceded by a similar rumbling to the sounds heard in Tree of Life, the film’s soundtrack takes the lead sonically and conveys the character’s emotional state.

Creating your own explosion sound effects

Explosions often involve the careful use of EQ, compression, and reverb. Equalization can help shape the deeper impact layers, while compression controls the dynamic range of the explosion, making it more consistent and punchy. Reverb, on the other hand, is crucial in placing the explosion in a believable space reflecting its size, proximity, and the environment.

If you’d like to try creating your own explosion sounds from scratch, give this workflow a try.

Set up your DAW: Open your DAW and select a variety of kick drum samples. Try to find sounds with different characteristics so that they wont fight with each other and create interference. Experiment with using different pitches, attacks, decay and resonance.

Layer your kicks and apply effects: Start by layering two kick drums on separate tracks. Use the EQ to highlight complimentary frequency ranges and blend them together. Adjust the volume levels of each layer to balance the impact and intensity of the explosion. Then apply effects like distortion, phasers, and reverb.

  • Apply distortion or saturation to add grit and crunch to the explosion.
  • Use a transient shaper to emphasize the attack of the kick drums, making the explosion sharper and more impactful.
  • Apply some reverb or delay to create a sense of space and depth, simulating the reverberations of an explosion.

Add layers of foley: To make the explosion SFX even more realistic, consider adding additional layers of sound. Whooshing sounds can simulate the rush of air before the explosion. High frequency crackles after the initial sound will simulate debris.

Mix and Master: Once you’ve arranged and edited your explosion, spend some time mixing and mastering the final result. Ensure that the sounds are balanced continue using compression and EQ to until they sound polished.

Save, export, and sync: Once you’re satisfied with your creation, save the project and export the explosion as an audio files in a format suitable for your needs (e.g., WAV, MP3). Then add these to your video editor to see how they site in the film.
