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 and has skyrocketed over the past year. The field of audiometry is no exception. Due to logistical challenges, it is often difficult to gain access to the audiometry hardware and other resources required for training and practice. AvatarAudiometer helps lessen 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 inter-octave frequencies between 250-8000 Hz. The virtual patients' responses to tones are based on their individual hearing level thresholds. 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 brief description of each virtual patient’s case history, and 2) a sample of several hundred 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 diagnostic pure-tone audiometric results on an audiogram, or entering and verifying screening results, is provided.
