<span>Simulation education for medical and health professional training bridges classroom learning and training in a clinical environment. Its use has been increasing over the past two decades. Guidance to avoid in-person contact due to SARS-CoV-2 has further increased demand. Pure-tone audiometry is part of an audiometric test battery used to evaluate the auditory system. At Case Western Reserve University, students typically learn to conduct audiometry in COSI 370: Introduction to Audiology. Under current pandemic circumstances, students are unable to gain in-person experience using standard hardware (an audiometer and calibrated headphones). AvatarAudiometer solves this problem via an interactive online tool that mimics a real audiometer and simulates patient responses. The system consists of a simulation of pure-tone audiometry and a tool for graphing results on a standard audiogram interface. AvatarAudiometer allows students to measure unmasked air- and bone-conduction thresholds for each ear at octave and interoctave frequencies, 250-8000 Hz. The virtual patients' responses to tones are based on their individual hearing level thresholds. Because real </span><span>humans are inconsistent in their responding, AvatarAudiometer patients differ from one another in their frequency of false positive/negative responses, range of reaction times, and duration of holding down the virtual response button. Two sources of patient audiometric profiles are included: 1) curated audiograms simulating specific types, configurations, and severities of hearing loss, along with a description of each virtual patient’s case history, and 2) a sample of 5470 audiograms representative of the United States’ population by age and sex selected from the CDC’s NHANES database. AvatarAudiometer includes a tutorial that demonstrates functions and settings of a standard audiometer. Students can complete numerous pure-tone audiometric exams and screen large cohorts of virtual patients to simulate a hearing-screening protocol. After testing is complete, an interface for plotting, editing, and downloading corresponding pure-tone audiometric results on an audiogram is shown. A professor may have students self-grade their audiograms by comparing the student-measured audiograms with those of the patient's "true" simulated pure-tone thresholds.</span>
