Beyond Perception · The Vanishing Tone

A 1 kHz tone inside a soft pink noise. Every half minute the tone is turned down a little, and at some point it vanishes into the noise even though it is still playing: masking. Then the noise around 1 kHz is carved out and the tone, at the same level, is heard again; when the noise returns to its old shape the tone vanishes again. The noise never gets louder; only the tone is turned down. A listening practice with no claim of any effect.

  • Reverb: room, 12% mix

In the room you can listen to each layer on its own, change its settings and save it as your own recipe.

Sound is generated on this device in real time; no files are downloaded from a server. There is a 10 s fade-in at the start and a 0 min fade-out at the end.

Compare with another sound

Hear both at the same loudness; drag the slider to the middle and they blend.

These two sounds can't share one recipe (different tuning or effects): listen to the samples one after the other.

S · Soundscape, no claim

No health or mental-effect claim at all; it is simply a soundscape.

This session isn't linked to any claim of effect.

A session's level is the weakest of its linked claims; it is never raised by a strong but unrelated claim.
