Otis — the virtual patient simulates a range of complex hearing defects so that correct audiometry can be administered without having to burden a patient at all. 

The software intelligently and realistically simulates the behaviour of the patient and detects possible user errors immediately. The program guides the learner through the exercises at several levels of difficulty and provides useful help.

Optimizing Education

Otis – the virtual patient shortens the time needed for training, as all types of hearing impairment can be simulated for audiometry testing at any time. In this way, proficiency in procedures can be improved, and the skills acquired can be put into practice significantly faster.

Using the program, experienced practitioners also have the opportunity to acquire routine in working with complex hearing impairments, thus decisively increasing client safety. The integration of autonomous learning concepts allows learners to work simply and efficiently wherever they are, and thus make best use of their time.

Developed by Experts

Otis – the virtual patient was developed in close cooperation with consultants at the University Hospital in Zurich, the Academy for Hearing Aid Acoustics in Lubeck and the Aston University in Birmingham. Otis – the virtual patient does not just set completely new quality standards; it has also been extremely well received by experts. Its fundamental benefits compared with traditional methods have led to educational and training institutions, private hearing aid dispensaries, medical practices and hospitals throughout the world integrating it into their training and staff development programmes within a short time after the product launch.


Otis – the virtual patient presents a completely new approach to running training courses for audiologists.

During the actual audiometry course, the instructors focus on teaching the theory and providing the participants with an introduction to using the program Otis.

After the course, the participants have the opportunity to deepen the theoretical competence they have acquired autonomously either on a distance learning course or in a suitably equipped skills lab and apply them with Otis – the virtual patient.

At the same time, exercises and analysis data are exchanged over the Internet so that each learner may be individually supervised and supported by the trainers.

These courses can finish with a test which the participants can take using a PC not tied to any particular location.

“Dear Mr. Wille, this summer I read your book on audiometry. To my opinion it is perfect! Especially Chapter 7.2 is very close to my experience! So I congratulate you with this thoughtful book. Kindest regards!“

“Our students have found Otis the virtual patient to be very useful in attaining the technical skills for testing. The case bank is particularly helpful in preparing students for a variety of hearing loss configurations prior to their first clinical encounters with clients.“
