What the evidence says
There is no research on 852 Hz. What is measurable: the ear is very sensitive in this range, so it will sound louder than a low tone at the same setting. Start quiet.
Where the number comes from
The modern solfeggio list traces to Joseph Puleo and Leonard Horowitz in the 1990s, who derived the numbers by digit-reduction of verse numbers in the Book of Numbers. It is not the medieval scale Guido d’Arezzo taught with the hymn “Ut queant laxis”, which named pitches, not fixed frequencies.
