A forthcoming app concept turns scientific sound recognition into a listening exercise: hear a signal, name its source, then read the science behind it.

For
People learning to identify scientific sounds by ear
Worth noticing
The page says each of its 26 signals includes a provenance stamp and the scientist who first understood it.

Field notes

The page frames each exercise as a short sequence: hear a signal, identify its source, then read the science behind it. It names a range from heartbeat to pulsar and says each entry carries a provenance stamp plus the scientist credited with understanding it. The site also states that decoding remains on the phone and that it uses no accounts, analytics, or advertising; these are homepage commitments, not independently verified implementation details.
