It starts as a sharp, rhythmic rattle. It’s dry. It sounds like someone dragging a stick across a wooden fence, but there’s a wet, biological clicking underneath it that makes your skin crawl. If you’ve played Naughty Dog’s masterpiece, you know that sound instantly. You don't even need to see the fungal growths or the ragged clothes to know you're in trouble. The clicker sound in The Last of Us isn't just a clever bit of audio engineering; it’s a psychological trigger that turns a confident player into a shivering wreck in about three seconds flat.
Honestly, it’s iconic.
Most horror games rely on loud bangs or screeching violins to scare you. The Last of Us went the other way. It used nature. Specifically, it used the concept of echolocation, turning a physical disability—the Cordyceps fungus blinding its host—into a predatory advantage that sounds absolutely repulsive.
The unexpected origin of that clicking noise
You might think a sound that terrifying came from a high-end synthesizer or some expensive Foley studio trick involving breaking bones and squishing fruit. Nope. The reality is much more human. And way creepier.
The clicker sound in The Last of Us was primarily voiced by actress Misty Lee. She’s a legend in the industry, but what she did for this role was basically vocal gymnastics. During the audition process, the team at Naughty Dog knew they needed something that didn't sound like a standard "zombie." They wanted a sound that felt like a machine trying to be a person, or maybe a person being overwritten by a parasite.
Misty Lee experimented with various "vocal fries" and deep throat clicks. She hit upon this specific, glottal rattle that felt both rhythmic and unpredictable. Phillip Kovats, the lead audio designer, has talked before about how they layered these organic human performances with other elements to get that final, bone-chilling effect. They didn't want it to sound like a monster. They wanted it to sound like a throat full of mushrooms.
It worked.
When you hear that noise, your brain doesn't just process "enemy nearby." It processes "predator." Because the clicking is functional—the creature is literally mapping the room with sound—you feel hunted in a way that a generic moan or growl just can't replicate.
Why the clicker sound in The Last of Us is a masterclass in game design
Game mechanics usually stay behind the curtain. You don't think about the code while you're playing. But the clicker sound bridges that gap perfectly. It’s a "tell." In game design, a tell is a signal to the player that an event is about to happen or an enemy is in a specific state.

Think about it.
- The Idle Click: This is the slow, rhythmic rattle. It tells you the Clicker is "searching." It’s calm, but it establishes the perimeter. You know exactly where they are without seeing them.
- The "Spotted" Shriek: When the clicking breaks into a high-pitched, frantic scream, you know the echolocation has hit a solid object—you.
- The Feeding Sound: This is the worst. It’s a wet, slurping version of the click that happens when you fail a stealth encounter.
The audio team used these variations to create a language. You aren't just listening to noise; you're translating their behavior. If you’re hiding behind a desk in a darkened hallway in Pittsburgh, that clicking tells you everything you need to know about your chances of survival. It's the ultimate tension builder because it never stops. It’s a constant reminder that the environment is hostile.
The science of the shiver
There’s a reason this specific frequency messes with us. Humans are biologically hardwired to react to certain sounds. High-frequency, non-linear sounds—think a baby crying or a woman screaming—trigger our amygdala. That’s the "fight or flight" center of the brain.
The clicker sound in The Last of Us hits those non-linear notes perfectly. It’s jagged. It doesn't follow a smooth melodic curve. It’s "broken" audio. When we hear it, our brains register it as a sign of biological distress or a predator's warning. It's why even after ten playthroughs, hearing that rattle in a quiet basement still makes your heart rate spike.
The HBO show had a massive challenge here. How do you translate a sound that is so tied to a gameplay mechanic (stealth) into a passive viewing experience? They brought back the original sound designers and even used some of the original vocal assets because you simply cannot improve on perfection. When the Clickers appeared in the fourth episode of the series, the sound was what did the heavy lifting. You didn't even need to see them in the shadows. That clicking did all the world-building for you.
How to use this knowledge in your own projects
If you’re a creator, a sound designer, or just a nerd who loves horror, there are actual lessons to take away from the clicker sound in The Last of Us. It’s not about making the loudest noise. It’s about making the most "wrong" noise.
- Humanize the monster: The scariest part of the Clicker is the hint of the human underneath. Use human vocalizations as a base, then distort them.
- Function over form: Don't just make a "scary noise." Give the noise a job. If the creature uses the sound to hunt, the sound should change based on what it finds.
- Contrast is king: The clicking is terrifying because the rest of the world in The Last of Us is often deathly silent. Silence is the canvas; the click is the paint.
The legacy of this sound design is huge. You see its influence in modern horror games everywhere now. Designers are moving away from the "loud roar" and toward the "disturbing tick." It’s more intimate. It feels like it’s right in your ear.
If you really want to appreciate the engineering, go back and play the "basement" sequence in the hotel in Part I. Turn off the music. Just listen. The way the clicking bounces off the tiled walls is a masterclass in 3D audio. It’s not just a sound effect; it’s a character in its own right. One that wants to rip your throat out.

To truly understand the impact of the clicker sound in The Last of Us, you have to look at how it redefined the "zombie" genre. We stopped calling them zombies. We started calling them Infected, and eventually, just Clickers. The sound became the identity.
Practical steps for horror fans and creators
If you want to dive deeper into the world of game audio or just want to survive your next grounded-difficulty run, keep these things in mind.
First, invest in a decent pair of open-back headphones. The soundscape in this game relies on "air." You need to hear the directionality of the clicks to navigate the stealth sections effectively. Second, pay attention to the "breath" between the clicks. Naughty Dog added subtle heaving and wheezing sounds that indicate how close a Clicker is to "venting"—that’s when they're most likely to turn around or change their patrol path.
Finally, for the aspiring sound designers out there, study the work of Gustavo Santaolalla and the Naughty Dog foley team. They didn't just make a game; they built an acoustic nightmare that has lived rent-free in our heads for over a decade.

Stop looking for the monster. Start listening for the rattle.
The next time you’re in a quiet room and you hear a floorboard creak or a pipe tick, just pray it isn't rhythmic. Because if it starts clicking, you're already out of time.
Go watch the "Making Of" documentaries for the original game and the HBO series. They show the actual vocal recording sessions with Misty Lee and the foley artists. Seeing a human being make those sounds into a microphone is somehow even more disturbing than seeing the Clicker itself. It reminds you that the horror is always closer than you think.
