Ever walked past a thin apartment wall or stayed in a budget hotel and heard that unmistakable rhythm? It’s awkward. Sometimes it's hilarious. But mostly, it’s just a biological reality of being human. People having sex sounds is a topic we usually giggle about or ignore, yet it’s rooted in fascinating evolutionary biology and psychology. Most of us assume those moans and gasps are just involuntary reactions to feeling good. That's part of it, sure. But research suggests there is a lot more "social signaling" going on than we’d like to admit.
It’s not just about the noise itself. It’s about why we do it.
The Science of Copulatory Vocalizations
Scientists have a very unsexy name for this: female copulatory vocalizations (FCVs). While men certainly make noise, the bulk of academic research focuses on women, largely because the patterns are more distinct and, frankly, more strategic. A landmark study published in the journal Archives of Sexual Behavior by researchers Gayle Brewer and Colin Hendrie flipped the script on why women vocalize. They found that many women reported making noise not necessarily because they were at the height of an orgasm, but specifically to help their partner reach theirs.
It’s a bit of a performance.
This doesn’t mean it’s "fake" in a malicious way. Think of it more like verbal encouragement. It’s a feedback loop. When one person hears the other enjoying themselves, it boosts their own arousal. It's a psychological bridge. You hear a sound, your brain registers "this is working," and your own physical response ramps up. If you've ever been with a partner who is "the silent type," you know how much harder it can be to gauge the vibe. Silence can be a bit of a mood killer for some, mostly because it lacks that data stream of affirmation.
Why Do We Get Loud?
There are a few different theories on why we can't seem to stay quiet.
The Evolutionary Signal Theory
In the animal kingdom, vocalizations during mating serve a purpose. In some primate species, a female’s calls can incite competition among males, ensuring she mates with the strongest. In humans, it’s a bit more nuanced. Some evolutionary psychologists suggest that making noise serves to "claim" a partner or signal satisfaction to strengthen the pair bond. It’s a way of saying "this is happening, and it’s good."
The Physical Release
On a purely mechanical level, sex is a workout. You’re holding your breath, your heart rate is spiking, and your muscles are tensing. When you finally exhale or release that tension, it naturally comes out as a sound. It’s the same reason people grunt at the gym when they’re deadlifting a heavy bar. It’s a physiological release of pressure.

The Feedback Loop
Let’s be honest: we like to know we’re doing a good job. Sounds act as a GPS for sexual encounters. A shift in pitch or volume tells your partner to keep doing exactly what they’re doing—or to pivot. Without it, you’re basically flying blind.
Cultural Influence and "The Porn Effect"
We can't talk about people having sex sounds without mentioning the massive influence of media. If you grew up watching mainstream adult content, your idea of what sex sounds like is probably skewed. In those videos, the vocalizations are dialed up to eleven for the sake of the audience. They’re loud, constant, and often sound like a theatrical performance.
This has created a weird kind of pressure.
A lot of people—men and women alike—feel like they should be making noise. They worry that if they’re quiet, their partner will think they’re bored. This leads to "over-vocalizing," which can sometimes feel a bit disingenuous. Honestly, it’s okay to be quiet. It’s also okay to scream the house down. The problem starts when the noise is a performance for someone else's benefit rather than a natural expression of what's happening in your body.
Experts like Dr. Justin Lehmiller, a research fellow at the Kinsey Institute, often point out that our sexual behaviors are heavily shaped by what we think is "normal." If you think loud moaning is the universal sign of pleasure, you’ll likely try to emulate it. But real-life sounds are often much messier. There’s heavy breathing, laughter, weird wet noises, and the occasional "oops" when someone bumps their head on the headboard.
That’s the reality. It’s rarely a polished soundtrack.
The Health Benefits of Being Vocal
Believe it or not, making noise might actually make the sex better. Not just for your partner’s ego, but for your own physical response.

- Breath Control: Vocalizing forces you to breathe. Many people subconsciously hold their breath when they’re close to climax, which can actually dull the sensation. Making noise ensures oxygen keeps flowing.
- Presence: It’s hard to get stuck in your head about your "to-do" list for tomorrow when you’re actively engaged in the sounds of the moment.
- Vagal Tone: Some experts suggest that certain types of low-frequency vocalizations (like deep moaning) can stimulate the vagus nerve, which helps the body relax and stay in a "rest and digest" or "arousal" state rather than a "fight or flight" state.
Dealing with the Neighbors
Since we’re talking about people having sex sounds, we have to address the elephant in the room: the neighbors. In densely populated cities like New York or London, soundproofing is a joke. Most of us have been on one side of the wall or the other.
It’s a social minefield.
If you’re the one making the noise, you might feel self-conscious. This "spectatoring"—where you’re imagining what the people in the next room think—can totally kill your arousal. On the flip side, if you’re the neighbor, it’s just plain awkward. Most people take the "don't acknowledge it" route. However, if it’s a nightly occurrence at 3 AM, it becomes a lifestyle issue rather than a biological curiosity.
The best advice? Rugs. Heavy curtains. Bookshelves against the shared wall. Or, you know, just accept that humans are mammals and mammals make noise.
Breaking Down the "Silent" Stigma
There’s this weird idea that if you aren't making a lot of noise, you aren't having a good time. That's just flat-out wrong. Everyone’s nervous system is wired differently. Some people become incredibly focused and quiet when they’re highly aroused. For them, noise is a distraction.
It’s about communication.
If you’re with someone new and they’re quiet, don’t assume they’re bored. Ask. Or look for other cues—tension in the body, changes in breathing, or eye contact. Sounds are just one tool in the kit. They aren't the whole kit.

Actionable Insights for a Better Experience
If you want to navigate the world of vocalization more comfortably, here are a few things to keep in mind:
Focus on the breath first. Instead of trying to make "sexy" noises, just focus on deep, audible exhales. It naturally transitions into vocalization without feeling forced or fake. It helps you stay present in your body.
Talk to your partner. Seriously. Ask them if they like noise or if they find it distracting. Some people find it incredibly hot; others find it takes them out of the moment. You won't know unless you ask.
De-center the "O." If you're making noise just to signal that you've reached a climax (or are about to), you're putting a lot of pressure on that one moment. Try vocalizing throughout the entire experience. It builds tension and makes the whole encounter feel more connected.
Own your natural sound. Whether you’re a screamer, a groaner, or a silent breather, lean into it. The most attractive sound is the one that’s actually authentic to what you’re feeling.
Basically, we make noise because we’re wired to connect. Whether it’s an involuntary gasp or a conscious "keep going," those sounds are the soundtrack to human intimacy. They’re a sign of life, a sign of pleasure, and—occasionally—a sign that your neighbor really needs to invest in some earplugs.
Next Steps for Better Connection
- Check your breathing: During your next intimate encounter, pay attention to when you hold your breath. Try making a conscious effort to exhale loudly.
- Experiment with pitch: See how different tones (low vs. high) affect your own level of arousal.
- Ask for feedback: Ask your partner, "What's one thing I do or say that really gets you going?" You might be surprised by the answer.
