Speech Masker

Noise strengthened in the speech band (0.5-2 kHz), with bass and treble turned down. Steady broadband noise can make surrounding sounds, such as conversation, less noticeable.

How is it made?

  • Pink noise

Sound is generated on this device in real time; no files are downloaded from a server. There is a 4 s fade-in at the start and a 0 min fade-out at the end.

Evidence

B · Moderate evidence

A few controlled studies or meta-analyses; reasonable but limited generalisability.

Helps mask surrounding sounds.

What do we know?
Auditory masking is an established psychoacoustic phenomenon: a steady sound raises the detection threshold of other sounds in similar frequency bands. This is why noise is used to cover ambient sounds.
What don't we know?
It is not clear that masking translates into protected sleep: in a 25-person lab study, adding pink noise to intermittent environmental noise worsened sleep structure further, and earplugs worked better. A systematic review warns that continuous noise may also affect hearing.
Sources and review note

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