By Borg, Eric, MD, PhD; Neovius, Lennart, MSc, Techn. Lic.; Ronnberg, Jerker, PhD; Journal of Rehabilitation Research and Development, Vol. 38, No. 2, pp. 257-263
Publication Date: March/April 2001

Study evaluating an eyeglass-mounted sound localization aid for persons who are deaf or deaf blind. The device was tested in an acoustic test room and an ordinary office by nine deaf and three deaf blind individuals. Results in the sound-treated room show an average hit rate of 80% overall and 100% for the front sector of the room covering 135 degrees. Results of the word localization test in a realistic communication situation in an ordinary office were 70% correct based on single presentations of the word and 95% following three presentations. Some difficulties involving deaf blind participants are noted.
