Baby Sleep Music: Safe Volume, Distance & Duration
Baby sleep music only helps if it's set up safely. Too loud, too close, or running on the wrong device — and you've turned a sleep tool into a hearing risk. Here's the Australian-safe setup.
1. Safe volume
Keep playback under 50 dB measured at the cot. That's roughly the level of a quiet conversation in the next room. A free phone decibel meter app is accurate enough to check.
2. Safe distance
- Minimum 1.5–2 metres from baby's head.
- Never inside the cot.
- Never on the cot rail or under the mattress.
- A shelf or chest of drawers across the room is ideal.
3. How long to play it
Loop the same lullaby for 20–30 minutes at the start of sleep — long enough to cover the first cycle. Many parents also leave a soft loop running all night below 50 dB to support cycle transitions during night wakings.
4. Devices that work
- Smart speaker on a shelf — easiest.
- Phone or tablet across the room — fine, but plug it in.
- Dedicated nursery sound machine with looping — best for night use.

Frequently Asked Questions
What's a safe volume for baby sleep music?
Under 50 dB at the cot — about the level of a quiet conversation. Red Nose Australia recommends keeping nursery sound levels low to protect hearing and not mask important environmental cues.
How far should the speaker be from the cot?
At least 1.5–2 metres from baby's head. Never inside the cot, never under the mattress, never against the side rail.
Can I play baby sleep music all night?
Yes, at low continuous volume. Many parents loop a gentle lullaby through the night to help with cycle transitions.
How do I measure 50 dB without a meter?
Free decibel meter apps on your phone are accurate enough. Aim for 40–50 dB measured at the cot, not at the speaker.
