About the 285 Hz tone
285 Hz falls in the warm low-mid part of the spectrum, low enough to feel grounded but high enough to come through clearly on most headphones and speakers.
Like 174 Hz, it is one of the extended Solfeggio tones rather than one of the classic six. This page plays it as a clean, steady sine wave, with no claims attached — set the volume and waveform to taste.
