Learn beluga’s sounds

Audio practice · Simulated examples

Practice while standing still. Listen through your earbuds. Left and right cues indicate the obstacle’s side. Faster repeats mean it is closer.

No camera or microphone is used in practice. These examples do not detect anything around you.

Vibration alerts

Strength changes pulse length, not motor intensity. Your phone controls the motor intensity. Audio still gives the obstacle’s direction.

Head-height obstacle

Two rising notes mean an obstacle near your head.

Edge or drop-off

Blocked path

Three taps mean an obstacle covers much of the walking corridor.

Other obstacle

A short wooden tick means an obstacle in your walking corridor.

Pole

A metallic ping marks a narrow, pole-like obstacle.

Bicycle

A double bell is the cue for a bicycle or motorcycle.
