Tones
Solfeggio frequencies
From 174 to 963 Hz, 10 tones, each one steady from start to end.
Under Tones, Background Noises plays 10 tones: 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz, the set usually called the solfeggio frequencies, plus 432 Hz. Each plays as one steady tone, and the player names it by its pitch only. On Premium a tone plays for up to 12 hours; the free plan plays a 60-second sample.

What are the solfeggio frequencies?
A set of nine tones that circulates in meditation and sound-bath communities, each with a traditional meaning attached to it. Those meanings are beliefs about the tones, not measured results, and we do not repeat them as claims. In Background Noises they are simply 10 choices under Tones.
The earlier app also gave each tone a name; the tiles now show its pitch only.
Why is 432 Hz in the list?
432 Hz is not one of the nine. It comes from a debate about tuning: most music today tunes the note A to 440 Hz, and some musicians prefer 432 Hz. The app already offered it beside the nine, so it stays.
What does a frequency tone sound like?
One pitch that holds steady, with no melody and no beat. The low tones, such as 174 and 285 Hz, sound like a soft hum. The high ones, such as 852 and 963 Hz, are brighter and can feel piercing at a high volume, so start them quietly.
Do I need headphones?
No. A frequency tone is the same in both ears, so it plays on headphones or a speaker. That is the difference from a binaural beat, which sends a different tone to each ear and needs headphones, and which Background Noises does not play today.
How long can a tone play?
On Premium, a tone plays for up to 12 hours, and the sleep timer can stop it after 15, 30 or 45 minutes, or 1, 1.5, 2, 4 or 8 hours. The Free plan plays the 60-second sample of each tone.
Which tone should I pick?
The one that sounds right to you. Try a low tone and a high one for a minute each and keep whichever you can leave in the background. If you want a place to start, 432 and 528 Hz sit in the middle of the range; sounds for meditation has more on using a tone for unguided practice.
Press play.
The Free plan plays a 60-second sample of everything. Premium plays the eight music and four nature stations, the noise colors and the tones for hours.
