Approximately 40 million adults in the United States alone suffer from anxiety and 61.1 % of these adults with anxiety disorders go untreated. Auditory Beat Stimulation is a therapeutic technique that uses a binaural beat to alleviate stress and anxiety symptoms, but this technique is also known to cause dizziness and discomfort to the user. Therefore, there needs to be a device that uses low sound frequencies to alleviate these disruptive effects as they arise in real-time. Based on previously conducted research, it should be designed to have three central frequencies: 10Hz, 20Hz, and 30Hz used for user customizable treatment and have them be 10db-30db. Our device hits those frequencies and volume range and targets the left vagal nerve under the left ear. Our device also consists of an Adafruit sound board connected to an audio amplifier to produce those necessary volume ranges, which will provide a speaker range from 10dB to 30dB. The verification of our device relies on two components: the frequency and amplitude of the output audio wave which will be verified. For our audio output, we will be using a dynamic moving-coil microphone sound transducer to convert it into an electrical signal, which will be fed into the oscilloscope to and then confirm its reliability with an acceptance rate of ±5 dB. For our signal output, we will verify the signal’s frequency range as well as its amplitude intensity with an acceptance rate of ±5 Hz of the central frequencies. Our device provides the potential to reduce the disruptive effects of adult stress and anxiety symptoms
