Question 1

What is brown noise and why does it help with sleep?

Accepted Answer

Brown noise is a low-frequency sound with more energy in deeper, bass-heavy frequencies than white or pink noise. The deep rumble masks distracting mid-frequency sounds like voices and traffic, making it especially popular for sleep and for people with ADHD who find it grounding. Sleep Chord includes Brown Noise as one of its six free sleep channels.

Question 2

Is pink noise better than white noise for sleep?

Accepted Answer

Pink noise has a more balanced frequency profile than white noise — equal energy per octave instead of per Hz — which most people find softer and less harsh. Research suggests pink noise can improve sleep depth and memory consolidation. Sleep Chord uses pink noise as the default sleep channel because it works for the broadest range of listeners.

Question 3

Do I need a wearable to use the Sleep Chord tracker?

Accepted Answer

No. The Sleep Chord tracker uses a 30-second morning log — bedtime, wake time, and a 1-5 quality rating — to compute your sleep score and detect patterns over time. Pro users can connect Oura, Apple Health, Fitbit, or Garmin (rolling out) for automatic data, but the tracker works without any device.

Question 4

How much does Sleep Chord Pro cost?

Accepted Answer

Sleep Chord Pro is $4.99 per month or $39.99 per year (save 33%) with a 7-day free trial. Pro unlocks unlimited sleep timer, full tracker history, the Sleep Coach AI chat, saved mixer presets, and the Dreamscapes premium audio tier when it launches. Sleep Chord Pro is also included in the $7.99/mo SkipSeek Pro bundle, which covers every SkipSeek property.

Question 5

Does Sleep Chord work with Alexa?

Accepted Answer

Yes — just say "Alexa, open Sleep Chord" on any Echo device. The Alexa skill plays the same six sleep channels as the website, and your Sleep Chord Pro subscription works on every Echo in your house without separate billing.
