Can You Find the Note Hiding in This Noise?

Listen to A and B at a comfortable volume. Which clip makes the note easier to pick out?

Reveal what changed
  1. 0:03 · A has noise from about 900 to 1,100 Hz.
  2. 0:05 · B moves the noise band to about 2,900 to 3,100 Hz.
  3. 0:12 · Hear the same 1,000 Hz tone on its own, then hear A again.

The tone stays at the same digital level. The two noise bands are matched in digital RMS. Noise close to the tone’s frequency can make it harder to hear. How clearly it comes through depends on the listener and playback.
