What makes these tools different

  • • Method-faithful. Each tool implements a standard audiology procedure, with the references in the page.
  • • Privacy by default. Audio is generated locally via the Web Audio API. No uploads, no tracking pixels, no analytics that follow you.
  • • Volume-capped. All tone-generating tools cap output at a software-safe ceiling, below typical conversation level.
  • • PWA-installable. Add EarLabs to your phone home screen and the tools work offline.
  • • Editorially-framed. Tools do not diagnose. Each result links to the matching plain-language explainer in the Notes section.
