Hertz & Health

Hertz & Health is an evidence-based acoustic design system created for pharmaceutical retail. Meykos, a Guatemalan pharmacy chain, turned its in-store audio environment into a direct health intervention using three distinct, purpose-calibrated audio zones.In the waiting area, 432 Hz soundscapes promote relaxation—a frequency associated in clinical literature with reduced heart rate and higher heart rate variability. In the shopping aisles, 417 Hz provides a smooth transitional backdrop that accompanies customers without cognitive overload. At the counter, pink noise creates sound masking to safeguard pharmacist-patient conversation privacy. Active since February 2026, the system transforms the pharmacy from a simple transaction point into the very first step of healing.
