When Sound Opens Wounds: Using Audio to Surface Hidden Trauma

Last Updated: July 30, 2025 by Michael Kahn. Published: June 2, 2025.

We often associate sound with comfort—music that relaxes, background noise that soothes, voices that calm. But sound also has the power to stir what lies beneath the surface. Many people live with trauma they’ve never fully acknowledged, not because they are in denial but because their minds have cleverly buried it beneath layers of daily life. The body may forget, but the nervous system remembers. And sometimes, the memory speaks in sound.

Sound as a Trigger, Not Just a Tool

You may have experienced a moment when a song starts playing on the radio, and you feel a certain type of something…. It might be tearful, it might be nostalgia, or it might rub you the wrong way for some reason. Or a particular tone of voice makes your stomach clench, and you don’t know why. These aren’t overreactions or coincidences. They’re signs.

Sound might entertain and distract, but it also stores emotional context. Our brains record not only what happened in moments of crisis, but what sounded like it happened. A slamming door, a whispered threat, a ringtone—seemingly harmless sounds can hold a timestamp from a painful chapter of your life. The auditory system, deeply connected to the limbic brain (the center for emotion and memory), makes it possible for trauma to be resurfaced, not in words, but in frequencies.

Listening Backward to Move Forward

In trauma-focused therapy, listening to sound becomes a guided process rather than a solitary experiment. A trained therapist may use curated soundscapes—ranging from ambient noise to specific environmental recordings—to help clients gently explore their reactions. This isn’t a dramatic re-experiencing of trauma but a careful decoding of the body’s response to sound. A therapist might ask you to describe what you feel physically when exposed to certain tones or layers of audio, noting where tension builds or where your mind begins to drift or resist.

These sessions allow for real-time co-regulation: when something surfaces, you’re not left alone with it. A therapist helps frame the experience, guiding you to name sensations or memories without judgment or rush. The goal isn’t to find a neat resolution in one session but to let sound act as a key—to unlock sensations that have been locked away without narrative. Over time, identifying these auditory triggers in a safe and supported space can lay the groundwork for more integrated healing. In this context, listening becomes an act of courage—and connection.

The Role of Silence

Silence itself is often overlooked in trauma recovery. But for many, silence is not neutral—it is charged. If your trauma involved waiting, hiding, or bracing for an outburst, silence may feel less like calm and more like dread. A lack of sound can mimic the ominous pauses before something bad happens.

If silence triggers restlessness, monitor how long it takes for discomfort to arise. What thoughts try to interrupt the silence? This is data which will help you to start recognizing your own wiring.

Music as a Mirror, Not Just Medicine

The benefits of music therapy are well-documented, but one rarely discussed function is its ability to reveal what hasn’t healed. When working with a trauma-informed music therapist, you might use specific songs not to “feel better” but to identify where your inner system breaks down. What lyrics offend you without reason? What tempo feels invasive? What instruments make you angry?

The discomfort here is diagnostic. By paying attention to what repels you sonically, you may discover the shape of past violations—times your voice was silenced, your rhythm interrupted, your harmony destroyed. Let music show you not only what you love but what you fear.

Let Sound Speak Where Words Fail

Not everyone is ready to talk about what they’ve been through. That’s okay. Talking isn’t the only way through. Sound, when approached with intention, can be a translator for pain that never learned the language of speech.

If you begin to notice patterns in what agitates or unsettles you auditorily, resist the urge to push it away. Instead, track it. Be curious. Every reaction has a root. The first step toward healing might not be talking louder—it’s listening deeper.
