Speech Intelligibility and Hearing Function in Navy Divers

Previously, Dr. Lucks Mendel served as Associate Director for the Center for Speech and Hearing Research in the National Center for Physical Acoustics at the University of Mississippi. During that time, she received over $500,000 of external funding to conduct research with Navy divers at the Navy Experimental Diving Unit in Panama City, Florida. These research projects focused primarily on studying changes in hearing physiology that occurred when Navy divers were at depth. In addition, studies were conducted that focused on developing ways to improve speech intelligibility and speech perception among divers who work in noisy environments under adverse conditions. Because Navy divers work at such deep depths and must breathe helium, the quality and intelligibility of their speech is affected. A related project focused on analyzing the acoustic characteristics of the helium speech that was produced. The effects of helium and pressure changes on speech production and perception were studied in order to make improvements in the communication systems used by these divers.
