How to play
Choose Mixed sounds, Animals, Transport or Everyday environment, then select Easy, Medium or Hard. Adjust your device and game volume to a comfortable level. Play the sound and choose the matching labelled picture with touch, mouse or number keys 1–4. Space replays the sound.
Easy is untimed with two choices and unlimited replay. Medium uses three choices, relaxed timing and three plays per question. Hard uses four choices, shorter timing and one play. Hints reveal the sound group and remove one incorrect choice.
Sound and learning boundary
All nine cues are symbolic sounds created in the browser with Web Audio; they are not field recordings and may sound different from real sources or assistive alert devices. This is general entertainment and sound-recognition practice, not a hearing, auditory-processing, attention, cognition or communication assessment. Stop or lower the volume if sound is uncomfortable.
