Sales to the European Union Temporarily Suspended

Due to difficulties in exporting to the EU since the removal of the de minimis exemption on July 1st, we have made the difficult decision to temporarily suspend sales to the EU. We are working as hard as we can to resolve this, and we hope that we can resume sales to the EU by the end of the year. If you wish to be notified when we resume sales to the EU, please subscribe to our mailing list for updates.

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.

For full technical specifications, please refer to the Ohr-1 Manual.
