See the sounds that matter.

Your world.
Made visible.

Turn everyday sounds into clear visual alerts.
Made for Deaf and hard-of-hearing people.

On your device. Always.

No audio uploads. No account.
Just you, and your surroundings.

A new purpose for an old device

A room that keeps you in the loop.

Turn a spare laptop or tablet into an always-visible sound display. Station mode keeps the clock, listening status and alerts in view.

What the model hears
  1. Waiting for sound

May miss sounds or false-alarm. Not a replacement for certified alarms. Keep this tab open; background listening is not guaranteed.

02 / Take a listen

Try it. No mic needed.

JUDGE FRIENDLY

Play a sound and watch it become an alert. Samples play through your speakers.

Synthesized test sounds (generated by tools/synth_sounds.py, CC0)

03 / Make it personal

Every home has its own sounds.

3 EXAMPLES. ONE NEW ALERT.

Your washing machine's little jingle. That particular door chime. Teach LoudNotice what matters to you.

1 Capture2 Capture3 Capture

Capture three examples of the same sound. Nothing is uploaded.

Your sounds

Only numeric sound fingerprints and labels are saved. Test audio stays in memory for this session.

Made personal. Shared with care.

Set up for someone you care about

  1. A hearing family member teaches the sounds of that home and adjusts the preferences.
  2. Choose Export setup to save everything in one file.
  3. On their device, choose Import setup, then test the sounds together.

Includes numeric sound fingerprints, labels and preferences. No recordings. Importing a setup replaces taught sounds and preferences. Notification permission must be granted on each device.

04 / Your preferences

A little fine-tuning.

Adjusts all built-in thresholds. Taught sounds have their own similarity slider.

Sounds to look out for

Icon + text + color, every time. Urgent sounds get priority.

Built with care, in the browser

Awareness, with privacy built in.

LoudNotice uses Google's YAMNet through MediaPipe Tasks Audio to recognize sounds on your device. It checks a one-second window every half-second, groups related labels, and turns matches into visual alerts. Taught sounds compare a 521-category fingerprint and a 32-band frequency profile with your examples.

Your audio stays yours.

Microphone audio is never uploaded or saved. Taught fingerprints, labels, preferences and alert history are stored in this browser. The model and runtime download from Google and jsDelivr; those hosts receive ordinary download requests. No accounts, trackers, or paid APIs.

A helpful prototype, not a safety device.

Noise, distance and similar sounds can cause missed or mistaken alerts. Confidence is a model score, not a calibrated probability. Keep certified alarms and other accessibility aids. Background tabs and locked screens may pause audio. Notifications do not keep listening alive.
