Free hearing tests & tinnitus relief. No ads, no tracking.

HearWell - Free Hearing Health Tools is a browser-based, open-source toolkit for hearing assessment and tinnitus management. It is designed for individuals exploring their hearing health, people living with tinnitus, educators, and researchers who need accessible, privacy-first audio tools.
The suite includes an online audiometer, tinnitus frequency finder, tonal tinnitus masker with multiple modulation options, a customizable noise generator with equalization, and notched noise generation. HearWell requires no account, runs entirely in the browser, and stores no personal data. Results are for informational and educational use only and are not a substitute for professional medical evaluation.
HearWell uses web audio technologies to generate and control tones and noise directly in the browser. Users select a tool, connect headphones, and adjust parameters such as frequency, level, modulation type, and equalization to explore hearing thresholds or create sound environments. No download or account is required.
The audiometer guides users through frequency-by-frequency threshold checks and plots results on an interactive audiogram chart. The frequency finder provides an interactive slider and waveform selection to help users match a perceived tinnitus pitch. The tonal masker offers multiple modulation modes (AM/FM/CR) for neuromodulation-style sound experiments. The noise generator supports ambient backgrounds and an 8-band EQ, and the notched noise tool produces spectrally notched noise around a selected frequency.
Accuracy depends on equipment, environment, and user interaction. These tools are not medical devices and are not intended for diagnosis or treatment. For any hearing concerns, users should consult a qualified healthcare professional.
