Method

Method-faithful

Each instrument implements a standard audiology procedure or NIOSH formula. References are at the bottom of every instrument page.

Privacy by default

Entered values stay in your browser and are not uploaded. Generic site analytics may record that a tool was used, but not the values you entered.

Volume-capped

All tone-generating instruments cap output at a software-safe ceiling, below typical conversation level. Your device volume is still your responsibility.

Educational, not diagnostic

These instruments do not diagnose. Each result page links to an editorial note explaining what your measurement means in clinical context.
