Demos

IWAENC 2022: We implemented a group conversation enhancement system using smartphones placed on a table. It preserves spatial cues even when the listener turns his head. This video is best experienced using headphones.

ASA Meeting 2022 & WASPAA 2023: We used a wireless assistive listening system, usually used to enhance the broadcast sound, to cancel it instead. The system removes the nuisance sound being played over the speakers. This video is best experienced using headphones.

ASA Meeting 2021: We implemented our immersive multiple-talker remote microphone system on the Tympan embedded hearing aid platform. The adaptive filter removes noise from the fan while preserving the spatial cues of each talker, even when they move. Best experienced with headphones.

WASPAA 2021: A binaural adaptive filtering system preserves the spatial cues of a moving talker while reducing background noise. Best experienced with headphones.

The Illinois RapidAlarm is a sensor and alarm system for use with emergency ventilators such as the Illinois RapidVent. It tracks breaths using a pressure sensor and alerts clinicians when it detects a problem.

Face masks muffle speech, making it harder to communicate, but not all face masks have the same effect. This video compares the acoustic attenuation of different face masks and demonstrates that lapel microphones can improve clarity.

WASPAA 2019: A motion-robust beamforming algorithm can separate speech even when the microphones in the array are moving relative to each other. Best experienced with headphones.

CAMSAP 2019: Demonstration of cooperative processing using wearable and smart-speaker devices. A distributed array of 160 microphones is used to separate sources and learn room acoustics parameters, then a wearable array of 16 microphones is used to perform real-time binaural beamforming. Best experienced with headphones.
