Online Versus Lab-Based Psychoacoustics

Brief description of study

The purpose of the study is to investigate the feasibility of performing lab-based psychoacoustic measures through a web browser. Cochlear implant patients are traditionally evaluated in the research lab using strictly controlled environments, such as sound proof booths and calibrated speakers. While these conditions allow for high levels of experimental control, they are not always feasible for patients who cannot travel to the lab. In this study, we will use an ABA design to determine the accuracy and ease-of-use of web-browser based psychoacoustic assessments. Patients will perform the experiments at home using written instructions, at the lab under experimenter supervision, and then again at home. We hypothesize that home-based assessments may show more variability, but will be highly correlated to lab-based assessments. The results of this study may enable us to reach more subjects and increase validity of the assessments.
