Introduction: TfCD Wearable Noise Display

This wearable noise display gives colored feedback on the noise level of your environment. With a sound sensor this set-up can warn you when the noise in your environment is to loud. When the LED circle hits the red zone it indicates possible hearing damage. Not all components are fitted inside the wearable. If you want to make this into a fully functional wearable you should use a different set-up with a microcontroller and a small battery to replace the Arduino and make it fit into a wearable embodiment. This product can be used on festivals, construction worksites or in other noisy environments.

Step 1: Gather Materials

Here are the components that you need to build the Wearable noise display:

Components:

  • Arduino Uno
  • NeoPixel Ring - 16 x 5050 RGB LED
  • Breadboard
  • Wires
  • Seeed Studio Geluidssensor SEN12945P
  • Casing
  • Watch strap

Solder it and use the following electronic scheme to connect all the components. Try it in a breadboard first to check that everything is working properly before soldering the components.

Step 2: Programming

The code below can be used to to upload to your arduino and transform the neopixel into a noise display.
To make the Neopixel and coding work, the neopixel library needs to be downloaded and included at the start of your code. In our case, we downloaded it from: https://github.com/adafruit/Adafruit_NeoPixel

Save the library in the arduino folder and go to sketch > include library and add the library.

The values chosen for the environmental noise and corresponding color have been chosen to illustrate the effect of increasing the volume and do not respresent a real scale for hearing issues. Youn can change these values according to your sensor, preffered scale.

Step 3: Design and Print

Measure the dimensions of your components and create your own embodiment design and/or interface.

For our prototype we used a 3D printed body design that would fit with any universal watch wrist band with a width of 20 mm. To cover up the inside of the design we cut a circle out of a 1mm thin plastic through witch the LED-ring would still be visible.

Feel free to use our design or create your own. When designing a version without the Arduino make sure that all components fit within your design.

Step 4: Assembly

Place all your components into the casing after the circuit has been made and the code has been uploaded. A special design can be created for the cover of your components. For example, frequency indicators to help read the data provided with the LED-ring or a cool logo to brand your design. Be creative!

Congratulations! Now you can use you can wear this cool device that warns you for damaging environmental noise, and looks cool while doing so.

I wonder if you could use parts from TinyCircuits in order to make it 100% wrist wearable.
