Ohr-1

A sound level meter built for music production, rehearsal and live sound.

Designed to be always on and always visible, the Ohr-1 provides an instant sound level reference for musicians and engineers. Whether you're mixing in the studio, rehearsing with a band, or working front of house, it gives you clear, immediate feedback without interrupting your workflow.

The Ohr-1 continuously measures A-weighted, Slow sound levels and uses a simple traffic-light display to indicate when levels exceed 85 dBA, a widely recognised threshold where prolonged exposure increases the risk of permanent hearing damage. By making sound levels visible at a glance, it helps reduce volume creep and minimise ear fatigue during long sessions.

Designed, engineered, hand-assembled and calibrated in East London.
