GammaTune Sync is a 40Hz light and sound kit for precise, synchronized gamma-frequency stimulation at home. It pairs a 40Hz flicker bulb with a compact speaker whose optical receiver detects the bulb’s pulsed light and plays a precisely synchronized 40Hz pulsed audio tone. This combined light–sound entrainment is something separate, unsynchronized light and sound devices cannot achieve. The 40Hz (25 ms) flicker timing follows the method described in MIT’s gamma research, and is intended to support focus and mental clarity.

Use is simple: replace a bedroom or bathroom bulb with the 40Hz bulb, or screw the bulb into the included switchable lamp holder for plug-and-play or travel use. Place the speaker within about 1.5 meters of the lamp, turn the light on, and adjust the speaker’s receiver angle to set the volume.

Features

  • Precise 40Hz light and sound synchronization: the speaker’s optical receiver locks to the bulb’s 40Hz pulsed light, so audio and flicker stay in time.
  • Better than buying a light device and a sound device separately—unsynchronized sources can weaken the entrainment effect.
  • 9W white LED 40Hz flicker bulb with a 25 ms period and 50% duty cycle, timed by a microcontroller.
  • Includes a switchable lamp holder for out-of-the-box use and travel.
  • Rechargeable sync speaker: 5W max output, about 2 hours to charge and 8 hours of continuous playback, with USB power for standby use.
