[SOUND WELLNESS] Why the Right Sound Changes Everything

The moment that changed everything

It started personally.

Ikuyi Minat — sound producer, engineer, and drummer who has performed with artists from over 60 countries — found herself avoiding the very spaces she loved. Not because of the crowds. Not because of the price. Because of the sound.

As someone with auditory hypersensitivity, and raising a daughter with the same experience, the background music in cafés, shopping malls, and luxury lounges wasn’t background at all. It was noise. It was exhausting. And it meant: we can’t stay here.

That personal reality became a professional mission.

Sound reaches the brain before anything else

Brands invest deeply in interior design, lighting, and scent. Yet sound reaches the brain in 0.1 seconds — faster than any visual cue — and most spaces leave it entirely to chance.

The result is an invisible problem. Guests can’t always name why a space feels tiring. They just don’t stay as long. They don’t come back as often. And for the estimated 15–20% of people who experience some degree of sensory sensitivity, a poorly designed sound environment isn’t just uncomfortable — it’s a reason to leave and not return.

In 2023, Walmart introduced Sensory-Friendly Hours across all U.S. stores: reducing BGM, dimming lights, and removing announcements during specific periods. The goal wasn’t altruism. It was a business decision — to reach a segment of customers who had been quietly avoiding the store for years.

Luxury brands are beginning to ask the same question: what if the sound is the reason they don’t stay?

What “neuro-diverse” sound design actually sounds like

This isn’t about playing music more quietly. It’s about engineering sound that works with the nervous system — not against it.

The human ear is most sensitive in the 3–8kHz range — the frequencies that cause fatigue when left unmanaged. Balancing this range keeps sound rich without becoming tiring. Beyond that, intentional sound masking wraps ambient noise — a dropped glass, a passing conversation — in a layer of texture that absorbs rather than startles. Dynamics are designed so there are no sudden shifts, but the natural warmth of overtones is preserved: the kind of sound where guests look up and realize an hour has passed. And every design accounts for the specific room — its speakers, its dimensions, its reverb — so the listening experience feels effortless, not engineered.
