About the 174 Hz tone
At 174 Hz the tone sits low in the bass, closest to the note F3. Because it is so low, full-range speakers or good headphones will reproduce it far better than a laptop or phone speaker.
174 Hz is one of the “extended” Solfeggio tones added below the traditional six. This page generates it as a clean sine wave — we make no claims about it; use it however it sounds good to you.
Because 174 Hz is so low, the waveform matters more here than at higher pitches: a pure sine gives a smooth, round tone, while triangle or square adds buzz and upper harmonics that small speakers can actually reproduce better than the deep fundamental. To fill out the low end, pair it with its octave at 348 Hz, or use it as a bass drone beneath brighter Solfeggio tones like 396 or 528 Hz.

Frequently asked questions
What note is 174 Hz?
174 Hz is closest to F3 — the F below middle C, a couple of octaves down. The generator shows the nearest note and the exact cents difference so you can place it on a keyboard or tuner.
Why can’t I hear 174 Hz on my phone or laptop?
174 Hz is a deep bass tone, and most phone and laptop speakers roll off in the low bass — so they may reproduce it faintly or not at all. Full-range speakers or over-ear headphones will render it far better.
Is 174 Hz a Solfeggio frequency?
It’s one of the extended Solfeggio tones added below the traditional six (396 to 852 Hz), and the lowest that is commonly listed. 285 Hz is the other extended tone near it.
