Sound Therapy

"Sometimes the most healing thing isn't a word. It's a frequency."

Sound has been used for healing across cultures for thousands of years — from Tibetan singing bowls to Indigenous drumming ceremonies to the simple act of humming. Modern neuroscience is now catching up with what ancient traditions always knew: sound directly affects the nervous system, brain wave activity, and emotional state in ways that can be profoundly helpful for trauma survivors.

This isn't about mysticism. It's about frequency, resonance, and the way sound bypasses the thinking mind and speaks directly to the body. For survivors whose trauma lives in the body rather than in words, that matters enormously.

Binaural Beats

"Two slightly different frequencies — one in each ear — that your brain blends into a single tone, shifting your brain waves in the process."

Binaural beats work by playing two tones at slightly different frequencies simultaneously — one in each ear through headphones. Your brain perceives the difference between the two as a third tone and naturally synchronizes to that frequency. Different frequencies produce different states:

• Delta (0.5–4 Hz) — Deep sleep, healing, unconscious processing

• Theta (4–8 Hz) — Deep relaxation, meditation, creativity, REM sleep

• Alpha (8–14 Hz) — Calm alertness, stress reduction, positive mood

• Beta (14–30 Hz) — Focus, concentration, active thinking

• Gamma (30–100 Hz) — High-level cognitive processing, insight

Research shows binaural beats can reduce anxiety, improve sleep quality, enhance focus, and support meditation — all of which are relevant for trauma survivors. Requires headphones to work properly.

Chanting & Toning

"The oldest sound therapy in the world — your own voice, used as a healing instrument."

Chanting and vocal toning use sustained sound made with your own voice to stimulate the vagus nerve, regulate the nervous system, and create internal resonance. You don't need to be a singer. You don't need to follow a religious tradition. You just need to make sound.

Simple practices include:

• Humming — The simplest vagal toning exercise. Close your mouth and hum on the exhale. Even 2 minutes produces measurable nervous system calming.

• OM chanting — The sustained vowel sounds in "AUM" create vibration throughout the chest, throat, and skull. Used in yoga and meditation for thousands of years.

• Vowel toning — Sustained sounds of A, E, I, O, U each resonate in different parts of the body. A simple but powerful somatic practice.

• Kirtan — Call and response chanting, often in Sanskrit. Increasingly available in secular wellness settings. The social element adds a layer of connection.

Where to start: Search "vagal toning exercises" or "humming for the vagus nerve" on YouTube. Insight Timer has guided toning sessions.

Sound Baths

"Lying still while being bathed in waves of sound from singing bowls, gongs, and other instruments — until your nervous system simply lets go."

A sound bath is an immersive experience where participants lie down and are surrounded by resonant sound — typically from crystal or Tibetan singing bowls, gongs, chimes, and other instruments. The term "bath" refers to being immersed in sound rather than water.

The experience works by:

• Shifting brain waves from beta (active thinking) to alpha and theta (relaxed, meditative states)

• Activating the parasympathetic nervous system — your rest and digest mode

• Reducing cortisol and promoting the release of dopamine and serotonin

• Creating a safe, passive experience that doesn't require effort or verbal engagement — particularly valuable for trauma survivors who find active practices overwhelming

Sound baths can be experienced in person at yoga studios, wellness centres, and community events — or at home through recordings. In-person experiences are more powerful but home practice is a meaningful starting point.

Where to find them: Search local yoga studios and wellness centres for live sound baths. Online: YouTube, Insight Timer, and Spotify have thousands of recorded sound bath sessions.

Sleep Sounds

"Because sometimes the most healing thing you can do is sleep — and sometimes trauma makes that nearly impossible."

Sleep is when the brain processes emotion and consolidates memory — both of which are disrupted by trauma. Sleep sounds create an auditory environment that helps the nervous system feel safe enough to rest. They work by masking disruptive environmental sounds, providing consistent sensory input that the brain can filter out, and creating an association between sound and sleep over time.

Types of sleep sounds:

• White noise — All frequencies at equal intensity. Effective at masking sudden sounds that might trigger alertness.

• Pink noise — Similar to white noise but with more low-frequency content. Research suggests it may improve memory consolidation during sleep.

• Brown noise — Deep, rumbling sound. Many people find it more soothing than white or pink noise — particularly those with anxiety or hypervigilance.

• Nature sounds — Rain, ocean waves, forest sounds, thunderstorms. Particularly effective because the brain processes natural sounds as non-threatening.

• Binaural beats (delta range) — Specifically designed to support deep sleep. Requires headphones.

Where to find them: YouTube, Spotify, the Calm app, and Insight Timer all have extensive sleep sound libraries. For dedicated sleep sound apps, try Relax Melodies or Sleep Sounds — both free to start.

A note from TJ

"I have always had trouble sleeping. It wasn't until about twenty years ago — when things weren't going well at work and my relationship with my spouse was struggling — that a counsellor I saw suggested Dr. Jeffrey D. Thompson's recordings. I didn't fully understand why they helped at the time. I just knew that something in my body settled when I listened.

I had always used music as an emotional regulator — long before I had words for what that meant. But now, years later and much deeper into understanding myself and how trauma lives in the body, I fully understand how significant sound can be. It doesn't just distract you from what you're feeling. It soothes something underneath it. Something the words can't always reach.

If you've never tried it — start somewhere simple tonight. Brown noise, a sound bath recording, or look up Dr. Jeffrey D. Thompson on Spotify or YouTube. See what happens."
