Close your eyes and listen. It’s a rhythmic, wet, staccato popping. It sounds like someone snapping dry twigs inside a bucket of jam. If you’ve played Naughty Dog's masterpiece, that noise—the The Last of Us clicker sound—probably just triggered a shot of adrenaline straight into your bloodstream. It’s visceral. It’s biological. It’s a sound that doesn't just tell you an enemy is nearby; it tells you exactly how you’re going to die if you make one wrong move.
Most horror games rely on shrieks or heavy footsteps to build tension. But The Last of Us did something different. It used a sound that feels broken. By taking a human voice and fracturing it into a series of rapid-fire glottal clicks, the sound designers created a predator that feels both familiar and utterly alien. You know there was once a person behind that noise, but that person is gone, replaced by a fungal parasite using their throat as a sonar device.
The Acoustic Horror of the Cordyceps
The clickers are the third stage of the Cordyceps Brain Infection. At this point, the fungus has burst through the host's skull, blinding them completely. To navigate, they use echolocation. This isn't just a cool gameplay mechanic; it’s a terrifying biological reality within the game's lore. When a clicker lets out that signature noise, it’s literally "seeing" the environment through sound waves bouncing off the walls, the rusted cars, and, eventually, Joel or Ellie.
Sound designers Phillip Kovats and Derrick Espino are the minds (and vocal cords) behind this nightmare. They didn't just use synthesizers or animal growls. They focused on the human element. Specifically, they worked with voice actors like Misty Lee, who is legendary in the industry for her ability to push the human voice into uncomfortable, non-human territories.
Lee has often talked about how she found the "click." It wasn't a scream. It was a localized vibration in the back of the throat. It’s a sound that feels like it’s being forced out through a windpipe constricted by fungal growths. When you hear the The Last of Us clicker sound, you're hearing the sound of a body being puppeteered by a parasite.
Why Our Brains Hate This Specific Noise
There’s a reason this sound works so well on a psychological level. It taps into "the uncanny valley" of audio. We are biologically hardwired to respond to human distress calls, but the clicker sound is a perversion of that. It’s rhythmic yet unpredictable.

The frequency of the clicks often sits in a range that the human ear is incredibly sensitive to. It’s "jagged" audio. While a smooth hum might be soothing, the sharp, percussive nature of the clicker’s vocalizations keeps the nervous system in a state of high alert. You can’t get used to it. Every time a click happens, your brain re-processes the threat.
In the HBO adaptation, the creators knew they couldn't mess with this. They brought in the original sound team and the original voice actors to ensure the The Last of Us clicker sound remained authentic. They understood that the sound is the character. Without that specific rattle, a clicker is just a guy in a mushroom mask. With it, it’s an apex predator.
The Technical Magic Behind the Mix
It wasn't just about the recording; it was about the layering. To get that "wet" sound, the audio team mixed in various organic elements. Think about the sound of fruit being crushed or the squelch of mud.
- Layer 1: The base human vocalization (the "rattle").
- Layer 2: High-frequency transients to give it that "snap."
- Layer 3: Wet, "gurgling" textures that suggest the host's lungs are filling with fungal spores.
This layering creates a 3D effect in the game's audio engine. If you're wearing headphones, you can hear the clicking move from left to right, growing more frantic as the creature senses your presence. It creates a suffocating atmosphere where silence is your only weapon, but the silence only makes the clicking louder.
The Evolution of the Click Across the Series
In the first game, the clicker sound was a warning. It was a signal to stop moving and crouch. By The Last of Us Part II, the sound evolved. The AI became more sophisticated, and the noises they made became more varied. You started hearing "conversational" clicks between multiple infected, suggesting a level of pack behavior that made the hair on your arms stand up.

The sequel also introduced the "Shambler," which had a much deeper, more resonant vocalization, but the clicker remained the gold standard for pure tension. Even with better graphics and more complex combat, the simple The Last of Us clicker sound remained the most effective tool in Naughty Dog's arsenal. It proves that what we hear is often much scarier than what we see.
Honestly, the brilliance of the sound design lies in its restraint. The clickers don't bark constantly. They click, then there's a pause. That silence is where the dread lives. You’re waiting for the next snap to tell you where they are. If they stop clicking, it means they’ve found something. Or they’re listening for you.
How to Handle Clickers Without Losing Your Mind
If you're replaying the games or jumping into the world for the first time, understanding the audio cues is actually a survival strategy. The clicks change based on the infected's state:
- Ambient Clicking: Slow, steady, and rhythmic. The clicker is just patrolling. You’re safe as long as you stay out of its direct line of "vision" (echolocation arc).
- Agitated Clicking: Faster, higher pitch. It’s heard something. It’s searching. If you’re throwing a brick, wait for this sound to peak before you move.
- The Scream: Once a clicker spots you, the clicking stops and turns into a guttural, terrifying shriek. At this point, stealth is over.
Most players make the mistake of moving too fast while a clicker is actively pinging the room. You have to move in the "dead space" between the clicks. It’s a rhythmic dance of death.
The legacy of this sound design has bled into the wider world of horror media. You can hear its influence in movies like A Quiet Place or even other games like Resident Evil. But nothing quite captures the specific, skin-crawling texture of the original. It’s a masterclass in how to use Foley art to build a world that feels lived-in, rotted, and dangerous.

Actionable Tips for Experiencing the Sound Design Properly
To truly appreciate the work that went into the The Last of Us clicker sound, you shouldn't just play through your TV speakers. TV audio compresses the dynamic range, losing those tiny, wet details that make the noise so effective.
- Use Open-Back Headphones: These provide a wider soundstage, allowing you to pin-point exactly where the clicking is coming from in a 3D space.
- Turn Off the Music: If you want a truly terrifying experience, go into the settings and lower the music volume. The raw, isolated sounds of the infected in a quiet hallway are ten times scarier than any orchestral swell.
- Listen for the Breath: Underneath the clicks, you can often hear the host gasping for air. It’s a reminder of the human cost of the infection and adds a layer of tragic horror to the encounter.
The next time you hear that rattle, don't just run. Stop. Listen to the texture of it. Appreciate the fact that a group of humans spent months figuring out how to make a sound that feels like a violation of nature. Then, maybe throw a Molotov, because appreciation won't keep you from getting your throat ripped out.
Mastering the Stealth Mechanics
To get the most out of the sound-based gameplay, practice "ghosting" through the subway sections in the first game. Try to navigate the entire room using only the audio cues of the clickers without ever being spotted. It changes the game from an action-shooter into a pure survival-horror experience where the The Last of Us clicker sound becomes your primary source of information. This level of immersion is exactly why the series remains a benchmark for the industry years after its initial release.
