Brown noise is deeper and stronger at the low end, without the high frequency sounds of white and pink noise. It can sound similar to the hard, gentle surf that comes with a storm. It's a unique frequency range and rare to find in many sound machines. Fortunately we do offer several sound machines with a brown noise profile:

<a href="https://www.soundofsleep.co.uk/product/soundsleep-se/">Sound+Sleep SE</a> - The Special Edition has a single brown noise profile, along with pink noise, white noise and 60+ other profiles. It's our flagship sleep machine with outstanding feedback.

<a href="https://www.soundofsleep.co.uk/product/soundsleep-mini/">Sound+Sleep Mini</a> - The Mini also has a single brown noise profile, along with 40+ other sound profiles. The mini allows for batteries and is more suitable for travel.
