Research Projects

Ear and Hearing Monitoring System (EHMS)

Funding Status: Application Submitted

This project aims to develop a dual-purpose earphone system that serves as both a hearing health monitoring device and a standard audio accessory. By utilizing the speaker as both an actuator and a sensor, the system provides a reliable, user-friendly, and cost-effective solution for proactive hearing care, benefiting users of all ages and establishing a foundation for future remote hearing health monitoring.

Advanced Non-Intrusive Hearing Health Monitoring System for Noise and Vibration Environments

Funding Status: Application Submitted

An advanced nonintrusive hearing health monitoring system is crucial in military or construction sites for safeguarding personnel's auditory and overall health. In order to minimize human subject test huddles, we will develop a stand-alone human dummy equipped with sound and vibration sensors/actuators (with/without hearing protection devices). To alarm the harmful noise and vibration environment, we will implement a real-time monitoring system that sends the monitored data remotely to report the noise/vibration pollution.

Female Hearing Health and Infrastructure in Rural America: from Virtual Solutions to Planning guide

Funding Status: Application Submitted

The proposed research aims to improve women's hearing health in rural US areas by investigating the impact of infrastructure on hearing loss, developing virtual infrastructure solutions, and reaching out to communities with developed solutions. This study will identify key factors contributing to female hearing loss and provide innovative digital therapeutics to enhance hearing health, ultimately guiding policies to reduce health disparities in rural communities.
