What is the 888 Hz frequency?
888 Hz is known as the abundance frequency, and it is the tone most people mean by the “money frequency.”
It is not one of the nine solfeggio frequencies. Its popularity comes from the number 8, a symbol of wealth in Chinese culture and of abundance in angel-number numerology.
People usually play 888 Hz for 15–30 minutes while journaling, visualizing a goal or repeating a money affirmation.
What is 528 Hz good for?
528 Hz is the solfeggio tone nicknamed the “miracle” or “love” frequency.
Listeners use it for relaxation, self-love meditation and moments of personal change.
It is one of the best-known solfeggio frequencies, and a calm starting point if you are new to frequency listening.
What is the money frequency?
“Money frequency” almost always means 888 Hz.
Close runners-up are 777 Hz for luck, 111 Hz for new beginnings, and 396 Hz, which is said to release fear and scarcity thinking.
Pair any of them with a single, specific intention, written down before you press play.
What are the 9 solfeggio frequencies?
The nine solfeggio frequencies are 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz.
The core six (396 to 852 Hz) were described by Joseph Puleo in the 1970s and popularized in the late 1990s; 174, 285 and 963 Hz were added later to make nine.
Every one of them plays free on this page.
432 Hz vs 440 Hz: what's the difference?
440 Hz has been the international standard pitch for the note A (ISO 16) since 1955.
432 Hz tunes that A about 32 cents lower, which many listeners describe as warmer and calmer.
The difference is small, so the best test is to play 432 Hz here and notice how it feels to you.
What frequency is best for sleep?
For sleep, most people choose a delta binaural beat between 0.5 and 4 Hz; SleepHz uses 2 Hz.
Delta brain waves (0.5–4 Hz) are the slow waves of deep sleep, and theta (4–8 Hz) is linked to drowsiness, which is why the 6 Hz track suits winding down.
Research on binaural beats is small and mixed, so treat them as a relaxation aid. Brown noise, ocean waves and rainforest rain are the simplest options if you just need to mask a noisy room.

Frequently asked questions
Do I need headphones?
Only for the binaural sleep tracks marked with headphones. They play a slightly different tone in each ear, which your brain hears as a slow beat. Every other frequency sounds fine on any speaker.
How long should I listen to a frequency?
Most people listen for 15 to 30 minutes for meditation or intention-setting. For sleep, set Auto-stop to 1 to 8 hours and let it fade out on its own.
How loud should it be?
Quiet. Keep it at a low, comfortable level, under 60% of your device's maximum, especially with headphones or overnight.
Is SleepHz free?
Yes. Every frequency on this page plays free in your browser, with no app or account.
Does it keep playing with my screen off?
On most computers, yes. Some phones pause web audio when the screen locks, so keep the tab open and dim the screen instead.
What do 777 and 111 mean?
They are angel-number favorites. 777 is tied to luck and alignment, and 111 to new beginnings, so people choose them for the meaning of the number as much as the sound.
Is this a medical treatment?
No. SleepHz is for relaxation, meditation and intention-setting, and it is not a medical device. For ongoing health or sleep problems, talk to a doctor.
