3Pcs DIY White Noise Signal Generator Kit Two Way Signal Output
Simple but effective white noise generators. Price is unbeatable...
This is a nice kit and very useful for treating the problems of sleeping due to Tinnitus, (Ringing in the ears). Build the kit and place by the side of your bed when sleeping. Helps me with sleeping. Hope it helps you. (This is a personal help, don't know if it will help others).
WELL
Interesting product for a super low price. The first one I built oscillated unless the pot was set midrange. I left the pot off the other 2 & the fixed output works perfectly. Needs 12-13 VDC, won't work any higher or lower. Bandwidth is about 250 kHz. Overall recommended.
Générateur de bruit blanc en kit pour une utilisation en basse fréquence pour les tests de réponse comme pour soulager les acouphènes.
