How to Make a DIY Sound Switcher - Edu Purposes - Non Medical - Not a Susan Shore Device
This is an electronic post on how I made an Arduino sound switcher, there is no Medical Device being sold or made, or BI-Modal Stimulation Kit being sold here nor is any of this intended for human use. This project is being posted as an electronic learning and research initiative because 10% of the world population has Tinnitus and there is no consumer level solution or therapy available, that works, yet. Auricle (Susan Shore) has not publicly launched a product. I can’t wait for us to have that product.
What you’ll need to make an Arduino Uno Based Sound Switcher
Arduino Uno with MP3 Music Maker Shield
The Arduino Sound Switch Program (.ino Sketch) that times Sound with Relay (Switch) . You can make your own.
MosFat Relay
9 Volt Battery to Power Arduino or Relay
USB Cable for Arduino
White Noise application to make your custom Tinnitus Frequency MP3 tone Burst
The Other Device you want to switch
How it works.
The Arduino program connects with stacked MP3 Music Shield and sends a signal to activate a relay to a customized time setting of your choice. Another line of code tells the MP3 player to play a sound clip for a duration and turn it off. This could be a song, a frequency tone, or burst of white noise, your choice. This relay can turn an electrical device on and off like a LED bulb or Tens Device. Sound essentially grouping the right devices you can control and drive Multi-Mode Stimulation.
Here’s a Snippet of the Code. Time is in Milliseconds 500 = 5ms
// Define timing
#define OtherDevice_ON_TIME 500
#define SOUND_DELAY 100
#define MP3_ON_TIME 2500
#define OtherDevice_DELAY 100What is duration of the Other Device?
Based on Linked Research supposed to be 2.2ms electrical stimulation consisting of 3x of biphasic pulses 100us pw 1000hz freq rate according to this study: https://www.frontiersin.org/articles/10.3389/fnsys.2015.00116/full#h3
My Other Device only goes to 150hz unfortunately. Not sure what difference it will make. Would love to be able to replicate conditions of original study better.
What’s is the duration of tone?
10ms with 1ms linear fade in and 1ms linear fade out.
Delay of Tone?
Tone repeats five times per second… so at 0ms, 200ms, 400ms, 600ms, 800ms, then it cycles like that
Delay from end of each tone to electrical stimulation starting is 5ms.
Freq of tone?
I matched my personal tinnitus spectrum by ear up to 8khz with a pink noise I filtered with linear phase eq and then mixed in a 3.36kHZ sine tone which is my tonal Component im hearing.
If I use pink noise that goes higher than about 8khz, I excite the neurons responsible for really high treble, and my tinnitus actually gets worse for a few hours. Really high pitched broad band noise. Not sure if this is due to timings not perfect or why that is. (My tinnitus is broadband in nature, like White noise + tonal Component at 3.36KHz)
What’s Next
Im thinking of trying an ear electrode and see if that would work too. University of Minnesota says this on their tinnitus research page: Further studies in the lab have revealed that paired acoustic stimulation (e.g., broadband noise) with electrical stimulation of the trigeminal nerve, including the ear and tongue, can drive strong plasticity within the auditory system relevant for tinnitus treatment.
