Anyone who works with sound knows the tuning fork: one fork, one pitch. Generateur Frequence, a small maker shop in Arles, France, offers a different kind of tool – a bare electronic board on which the frequency is typed in rather than picked from a set.
How it differs from a fork
- Any value between 0.01 Hz and 100 kHz, entered on a keypad and confirmed with OK.
- It starts at 7.83 Hz, the Schumann resonance fundamental, which lies far below the range of human hearing.
- The signal leaves the board through two flat spiral coils rather than through a speaker. To hear audible settings, plug your own headphones or speaker into the 3.5 mm jack offered as an option.
- No striking and no fade-out: the sine wave holds steady for as long as the 5 V micro USB supply stays on.
The shop sells it as an instrument and an object of curiosity for people interested in ambient frequencies. Nothing medical is intended and no effect is claimed. €59 with free tracked shipping, USB cable included: see the board's product page (https://generateurfrequence.fr/produit/generateur-schumann/) on generateurfrequence.fr (https://generateurfrequence.fr/).
