Innovative, affordable non-electronic headphones improve quality of life for those with mild to moderate hearing loss

Quantum Senses today announced that its innovative new hearing product (EARCOUSTIC) has completed testing in the University of Maryland’s Hearing Technology Lab and has been approved by the Principal Investigator for grant submission.

The EARCOUSTIC headphones were invented by Justin Lee, Founder and Chief Executive Director of Quantum Senses. Lee was inspired to create a heartfelt solution for a friend, a Vietnam veteran, who struggled to hear the TV at night without disturbing his wife.

Lee, an Aerospace Engineer with a robust educational background, specifically sought to develop an affordable solution for many who do not have health insurance coverage or coverage that does not cover the cost of obtaining expensive hearing aids.

He invented EARCOUSTIC as a hearing amplifier for mild to moderate hearing loss that is highly affordable, lightweight and compact, and does not require electronics, batteries or wires.

Lee launched EARCOUSTIC in the fall of 2024 and recently completed testing in the University of Maryland’s Hearing Technology Lab where it was approved for grant submission. The lab is focused on improving the benefit and use of hearing aids through the study of values and measurements used in fitting and validation.

“EARCOUSTIC is a disruptive technology that can substantially improve the quality of life for those with mild to moderate hearing loss,” said Dr. Eric Hoover, Assistant Professor, Department of Hearing and Speech Sciences, University of Maryland and Principal Investigator for the lab. “We have developed a grant submission to compare it to technologies that cost 100 times more and expect a similar benefit in a noisy environment like a restaurant.”

“Quantum Senses recognizes the importance of delivering a budget-friendly, non-electronic option for individuals facing hearing loss who may struggle to afford traditional devices,” Lee said. “The EARCOUSTIC headphones offer superior sound amplification at a price point of $19.99 making them accessible to those on fixed incomes. Our product is designed to complement, rather than replace traditional hearing aids and is ideal for watching television, attending church, participating in meetings, or enjoying a movie at home, work, theatres, concerts and more.

Notes to editors

Notes to Editors *** KEMAR Testing performed by Dr. Eric Hoover, Assistant Professor, Department of Hearing and Speech Sciences, University of Maryland, and Principal Investigator for the Lab*** EARCOUSTIC and KEMAR: Advancing Hearing Performance Analysis The EARCOUSTIC device was rigorously evaluated using KEMAR (a standardized acoustic mannequin designed for hearing-related testing) to validate its real-world hearing performance. By comparing KEMAR test data with and without EARCOUSTIC, we ensure a clear and scientific assessment that resonates with hearing professionals. Predicting Hearing Performance Through Testing Hearing performance is often determined through standard tests that simulate real-world environments, such as noisy settings. These tests yield scores that indicate how well an individual can hear and function under various conditions. Leveraging KEMAR Data for Accurate Predictions With KEMAR, raw decibel data is collected under two conditions: one where EARCOUSTIC headphones are used and one where they are not. By applying community-approved prediction formulas, this data is converted into scores that mimic those of standard hearing tests. Demonstrating EARCOUSTIC’s Advantages The predicted hearing test scores allow us to comprehensively compare the hearing performance enhancements provided by EARCOUSTIC. This approach translates raw improvements (measured in decibels) into meaningful, real-world metrics that are well understood by the hearing community. By leveraging Dr. Hoover’s expertise, EARCOUSTIC can be directly compared to other hearing aids within a standardized framework, offering clear insights into its benefits and effectiveness. About Quantum Senses Founded in 2021, EARCOUSTIC became the first launched company product. Quantum Senses is dedicated to enhancing life and uniting communities through hearing. Our mission is to provide organic, innovative and affordable technology solutions to enhance holistic experiences through the five senses to improve the consumer’s quality of life.
