Hello and welcome to my second Action Project for my STEAM course, Light, Sound, and Time. In this unit, Sound, we took a deep dive into human hearing, sound waves, and the Doppler effect. The
Doppler effect is the phenomenon of a sound coming towards you sounding higher and then lower when that sound is moving away from you. Human ears hear by collecting sound vibrations into the eardrum, from there it moves through small bones called the ossicles, then the vibrations get converted into nerve impulses by the
cochlea.
We also took part in some amazing field experiences. One example was an amazing panel with four deaf (and one interpreter) members of The Chicago Hearing Society. There, we discussed the future of American Sign Language and assistive technology. For this action project, we created our own playable guitars called diddley bows. I hope you enjoy this project.
This is an image of my diddley bow with the harmonics marked. The harmonics show where to place the slider in order to shorten or lengthen the soundwave, therefore, changing the pitch of the sound.

In the end, this project was fun, yet challenging. It was a difficult task to build the diddley bow but now that it is all said and done I am very proud of what I built.
