I am particularly looking at making fire alarms more accessible to people with hearing loss, but need to go back to the initial psychoacoustic work done if it exists.

We are looking for possible post-doc candidates interested in auditory localization and multitalker speech perception. The program is administered by the National Academy of Sciences, and the stipend is relatively generous. There is no guarantee that funding will be available, but for the right candidate this could be a great opportunity. The deadline to apply for the fall cycle is November 1st. Note that the position is open only to US citizens and legal permanent residents (Green Card Holders). Thanks, Doug Brungart Increasing Information Transfer in Audio Display Systems Human audition is an amazingly complex modality capable of extracting spatial, spectral, and temporal information from multiple simultaneous sound sources even in adverse listening environments. However, most real-world audio display systems rely on relatively simple stimuli that fail to take full advantage of the inherent capabilities of human listeners. The goal of this research is to find ways to increase the amount of information transferred to listeners through audio display systems. The effort involves two broad areas of research. The first area focuses on the generation of robust and intuitive azimuth, elevation, and distance cues that maximize the transfer of spatial information in audio displays, especially in noisy environments that involve more than one virtual sound source. The second area focuses on improving the segregation of competing sound sources in complex listening environments, especially those that involve more than one simultaneous speech signal. A major component of this research is a study of the role that non-energetic "informational" masking plays in the perception of multiple speech signals.
