OTIS Audiometry Simulation Software

Otis the virtual patient (from can be use to practice basic audiometry and tympanometry and masking. We use it in our classes as it is a great way of developing your skills in audiometry without having the pressure of the time or the client’s ability to focus, while getting used to the controls and techniques required. If you’re learning how to carry out masking, it is an invaluable learning and evaluation tool and your don’t need to rely on your supervisor to explain results. 

Otis is a little bit like a real person, for example, your client can fall asleep if you take too long or shout if you present sounds that are too loud. You can view your otoscopy, history and tymp data as part of the assessment. There is reference data for masking and symbols.  You have real time evaluation and assessment of your procedure as you do the audiometry – it tracks your accuracy, time and errors. You can also progress from easier audiograms, to more difficult cases.
