Silent Meditation Timer
A very light breeze and an interval bell every 5 minutes. 20 minutes.
How is it made?
- Wind (ambient sound generated on your device)
- Bell · 180 Hz, pattern repeating every 5 min
Sound is generated on this device in real time; no files are downloaded from a server. There is a 8 s fade-in at the start and a 1 min fade-out at the end.
Evidence
B · Moderate evidenceA few controlled studies or meta-analyses; reasonable but limited generalisability.
Meditation programs have shown small positive effects on some anxiety measures, with moderate-strength evidence.
Evidence level B: Moderate evidence- What do we know?
- In a meta-analysis of 47 randomized trials with active controls (3,515 people), mindfulness meditation programs showed small positive effects on anxiety, depression and pain with moderate-strength evidence; evidence for stress and distress was low.
- What don't we know?
- This evidence mostly comes from structured 8-week programs; whether listening to a sound session alone has the same effect is unknown. Participants came from diverse clinical populations. The programs were not shown to be better than drugs, exercise or other behavioral approaches, and NCCIH notes that much of the research is preliminary.
A session's level is the weakest of its linked claims; it is never raised by a strong but unrelated claim.
Keep your device volume comfortable, preferably below 60%. You can also use your device's headphone-safety settings.
