Digital Signal Processing

The Digital Signal Processing (DSP) Laboratory undertakes research projects related to speech and audio processing with applications in hearing aids, assistive listening devices, and augmentative communication devices. Current research activities in the DSP lab include objective measurements of speech and audio quality, electroacoustic evaluation of hearing aids, development of handheld DSP devices, and evaluating the interaction between speech coder quality and hearing loss, especially in Voice over Internet Protocol (VoIP) communications.
