Bimodal Stimulation Using Auditory and Vibrotactile Stimuli for the Mitigation of Tinnitus

"The Neosensory wristband consists of four vibratory motors built into the strap of the wristband (Figure 1a). The motors are linear resonant actuators (LRAs), vibrating at 175 Hz, capable of rising from 0 to 50% of their intensity within 30 ms. The motor intensity can be controlled with an eight bit resolution, meaning each motor can be controlled at 256 different intensities. At the highest intensity, each motor vibrates at 1.7 GRMS. The motors are separated from one another at a distance of 18.2 mm and 19.2 mm for the small and large wristband sizes, respectively (center-to-center distances).~The top of the wristband is a module that contains the power button, user setting buttons, a microphone, and a microcontroller. Bluetooth communication is used to create the corresponding vibrations on the wristband. While the study app plays the tones, it also sends a Bluetooth command to the wristband such that the wristband vibrates in the appropriate illusory location."

Tones will be played through an app
