Seminars in Hearing Research at Purdue (SHRP)

Date: Thursday, October 6^th, 2022

Time: 10:30 – 11:20 AM

Location: LYLE 1150

Speaker: Harinath Garudadri (UC San Diego Qualcomm Institute of Calit2, Research Scientist)

Title: Open-Source Platform for Hearing Healthcare Research

Abstract: In this presentation, I will discuss my efforts to leverage Internet of Things (IoT) and smartphone technologies to address the multitudes of complex issues in healthcare innovations and translation. We developed an open-source speech processing platform (OSP), supported by grants from NIH, NSF, Army Research Labs, Qualcomm Institute of Calit2 at UCSD, and Wrethinking, the Foundation.  OSP comprises applications, algorithms, software, and hardware to extend current clinical research in situ and also enable new investigations beyond what is currently possible.  The applications are enabled by an embedded web server that hosts web-apps for monitoring and controlling the realtime engines. The algorithms include realtime, embedded signal processing libraries for hearing aids functions, electrophysiology, inertial measurement units (IMUs), and other sensors. The hardware is based on smartphone chipsets with connectivity and best in the class MIPS/watt performance enabled by economies of scale. The software is based on 64-bit Linux (Debian 10, buster) with custom enhancements to the kernel and drivers. In addition, we have developed an application specific integrated circuit (ASIC) and Linux drivers for an efficient, multi-channel, sensor readout. The latest release includes a processing and communication device (PCD) in a in a wearable form factor of smaller than a deck of cards (~100 cm³), weighing 100 grams including a 3500 mAh battery. PCD connects to sensors and actuators (e.g. hearing aids) with wires and wirelessly in future. We currently are seeking collaborations to investigate the clinical benefits of OSP.  

Bio: Harinath Garudadri is a Research Scientist at the UC San Diego’s Qualcomm Institute of Calit2 and the founding director of the Technology, Healthcare, and Education Lab (THELab). He moved to academia in Nov. 2013 after 26 years in the industry to work on technologies that will improve healthcare delivery beyond hospital walls. He has a PhD in electrical engineering (1988) from University of British Columbia, Vancouver, B.C. where he spent half his time in ECE and the other half in School of Audiology and Speech Sciences, Faculty of Medicine. His area of expertise is signal processing applications in diverse fields such as speech recognition, machine learning, speech, audio and video compression, multimedia delivery in 3G/4G networks, low-power sensing and telemetry of physiological data, reliable body area networks (BAN), noise cancellation, and artifacts mitigation, among other areas. He has 54 granted patents and over 20 pending patents in these areas. His industry contributions have been incorporated into smart phones and commercial networks. Hari has over 60 peer-reviewed publications. His contributions were incorporated in 14 international standards specifications.
