ear3 is a sound level meter designed to protect live music audiences from noise-induced hearing loss without compromising the quality of their experience. With one billion young people at risk of permanent auditory damage globally, and no mandatory regulation in the UK live music industry, audience hearing health remains a largely overlooked problem.

It equips the people best placed to make a difference: sound engineers, DJs, and venue managers, with the tools to take ownership of that responsibility. It continuously monitors sound exposure against WHO safe listening guidelines, predicts limit breaches before they occur, and session data is accessible anytime for review and analysis. Built for grassroots venues, it brings professional-grade acoustic monitoring to those who need it most.
