Daniel-Jericho Johnson ’25 (Bachelor of Arts in Collaborative Audio Arts) delivered an impactful presentation, “How Audio Engineering Can Assist in Neurodivergent Hearing Loss Prevention,” at the Audio Engineering Society’s (AES) 2024 Show in New York City. Johnson’s innovative approach highlights the intersection of audio technology and audiology, aiming to create a more inclusive auditory experience for those with hearing disabilities and neurological conditions.
In their presentation, Johnson explored how audio engineering techniques such as compression, normalization, and parametric EQ can improve sound quality for musicians while also benefiting individuals with hearing impairments. They discussed the importance of electrical equipment resistance in enhancing audio fidelity and emphasized applying audio engineering knowledge to develop effective hearing solutions like in-ear monitors and earplugs.
“Approximately 3-9% of adults face some form of hearing disability, often compounded by neurological or psychological disorders such as PTSD and autism,” said Johnson. “Current hearing aid technology can sometimes be overwhelming, failing to provide the comfort needed for individuals with these comorbidities. My goal is to bridge the gap between audio engineering and audiology to create more accessible hearing solutions.”
Johnson’s senior project, “Better Hearing Through Noise Reduction,” seeks to prototype a hearing aid that integrates noise reduction techniques derived from audio engineering practices. They aim to develop a device that allows users to filter background noise while enhancing conversational clarity. Using an application to control the device’s settings, users will be able to adjust frequency responses based on their environment, making daily interactions more manageable.
“Through this project, I want to improve the quality of life for those who struggle with auditory overstimulation,” Johnson explained. “Inspired by my own experiences with PTSD and the challenges faced by my family, I am committed to developing solutions that empower neurodivergent individuals.”
“I am incredibly impressed with Daniel-Jericho Johnson’s presentation and the dedication they demonstrated throughout the development of this vital project,” remarked Director of Collaborative Audio Arts and Associate Professor of Music Production & Recording Technology Graham Spice, M.S. “Their innovative approach to problem-solving showcases their technical skills and their deep commitment to improving accessibility and fostering inclusivity within the audio engineering field. Their motivation and creativity in tackling such a complex issue are truly inspiring. I have no doubt that their work will significantly impact the lives of those with hearing disabilities and neurodivergent conditions.”
The project has garnered attention and support from industry professionals, including but not limited to Joe Tessone of Mystery Recording, Shannon Switzer of Sensaphonics, and Laura Sinnott with Sound Culture, who have offered resources to aid the research and development process. Johnson plans to document their progress through a series of vlogs, sharing insights and challenges encountered during the prototype development.
