What may come as a surprise is that the inventor of ResonX is hard of hearing, but that’s what makes Ethan Castro anything but a defeatist. Ethan was born premature which resulted in issues with his hearing. When he was very young, his doctor joked, “As long as you don’t go into music, you’ll be fine.” That didn’t stop him. Ethan loved music so much that he would hug his father’s speakers to feel every note of a techno song. This passion led him to become a professional audio engineer and composer (against his doctor’s advice). Today, Ethan is completing his Ph.D. in Digital Composition, researching how to perceive sound by combining hearing and feeling into a new audio format. Ethan showed his research to Valtteri Salomaki who was immediately sold and exclaimed, “Holy sh*t, this changes everything." This sparked EDGE Sound Research and our journey to fundamentally change how we perceive reality.
