Wesley Grantham, Professor in the Department of Hearing and Speech Sciences at Vanderbilt University, spends much of his time with Vanderbilt's audiology doctoral students, both in directing independent research projects in hearing science, and in teaching (Instrumentation, Binaural Hearing, Signals and Systems, and Computer Programming). Wesley is also Director of Research for the Department. In addition to conducting research projects in psychoacoustics, he coordinates Center-wide research efforts, such as the scheduling of in-house research meetings and the publication of the Bill Wilkerson Center Annual Research Report.

Wesley's research interests center around binaural hearing--that is, the way normal-hearing humans use their two ears in cooperation to process auditory information. Localization of sounds in space is one human ability that depends largely on our having two ears (you can appreciate this by plugging one ear and trying to localize sounds based on input only to the other ear). Recently, in collaboration with several colleagues in the Department, Wesley has been investigating the spatial hearing abilities of individuals who have received either one or two cochlear implants. Findings from these experiments have extended our knowledge about how the individuals with two implants can take advantage of the input to both ears in order to localize sounds with much better accuracy than individuals with a single cochlear implant.

Wesley is also quite interested in how humans perceive sounds that are in motion. There is some evidence that the auditory system is not very well specialized to perceive moving sounds; for example, while a moving visual object can be more detectable than a stationary visual object, moving auditory targets appear not to be more detectable than stationary targets. Wesley has published numerous articles in scientific journals on various aspects of spatial hearing in humans.

On the personal side, Wesley is married to Beth Grantham, a free-lance writer. They have three children: Jeff, Scott, and Lesley – all remarkably amazing individuals. Outside of work, he enjoys reading, listening to music (classical, blues), travel, astronomy, movies, reality TV, and French.
