FAQs.
The Ohr-1 is designed for anyone who spends long periods working around sound. Whether you're producing in the studio, mixing live shows, rehearsing with a band or teaching audio, it provides a simple, always-visible reference for monitoring sound levels.
It's used by music producers, mixing and mastering engineers, live sound engineers, musicians, rehearsal spaces, recording studios, venues and audio educators.
The Ohr-1 measures A-weighted, Slow time-weighted sound pressure level (dBA Slow) — the most widely used measurement for monitoring long-term sound exposure in music environments.
It continuously displays sound levels between 32–128 dBA, helping you keep an eye on your listening levels without interrupting your workflow.

The Ohr-1 is always on, always visible and purpose-built for music environments. It provides a constant reference without needing to unlock your phone or interrupt your workflow.

Long periods of exposure to high sound levels can contribute to permanent hearing damage.
By keeping your sound levels continuously visible, the Ohr-1 helps you spot level creep, build better listening habits and make informed decisions about when to reduce volume or use hearing protection.
The Ohr-1 provides up to 100 hours of battery life on a single charge and recharges via USB-C. Simply plug it in with any standard USB-C cable to keep it ready for your next session.
It can also be left plugged in continuously, making it ideal for permanent use in studios, rehearsal spaces and live venues.
