Oticon eCaps – a powerful hearing loss simulator for the iPad or PC
Much acclaimed by educational audiologists, this 1.5 MB hearing loss simulator is free for download and ready for use to demonstrate the effects of hearing loss to families, teachers, class peers and others. Once downloaded, to use: (1) From the “Who are you speaking with today” home page, tap on Pediatrics Segment. This takes you to the “Compose Your Agenda” page. (2) From the “Your Story” column you want to be sure to select “Audiogram” and “Speech in Noise”. (3) From the “What are the steps to better hearing?” column you want to be sure to select Hearing Aid Benefits and FM Benefits. Of course you can select as many other items as you want, but to be able to use the audio simulations you need the above components. (4) Then tap “Start” and then the forward arrow. This takes you to the audiogram page. (5) Input information about the child’s hearing in the right and left ear. (6) Then select Speech – the simulation options will pop up with images of a man, a woman and a child. Tap the forward arrow. Now you will be able to demonstrate the benefits of hearing aids. (7) Unmute and slide the slider to the right to increase the background noise. (8) To get to FM benefits, tap the forward arrow. This takes you to Oticon advances features and tap the forward arrow again. Now you are in FM benefits! Unmute and select listening options (no HA, HA and HA+FM). This can be done for school and home environments!
Oticon Professionals This is an updated version of the Oticon eCaps program. There are the same demos with entering in an audiogram, speech in noise, hearing aid simulation, hearing aid + FM simulation as there are with eCaps. There are also scenarios for Communication Strategies, How We Hear (goes over anatomy) and an Eye Chart (visual representation of hearing loss). information is also available about counseling, products and services.
Listening is hard work when you aren’t able to hear all of the speech sounds! Children with hearing loss are usually more fatigued than their typically hearing friends or siblings. For a brief article on this topic from Britain, download Tiredness in Deaf Children
Welcoming the Child with Hearing Loss into Child Care Not a simulation but good information to share with the parent and/or child care provider along with your suggestion to listen to a hearing loss simulation.
Thanks to all of the researchers who made these resources available!
Simulating unilateral or mild hearing loss with families? Purchase a pack of 15-pair from Supporting Success. Experiencing the listening challenges is a valuable strategy for facilitating understanding of the importance of ‘little hearing losses.’
Visual Simulations of the IMPACT of Hearing Loss
Simulations like the yellow story shown can be very effective in getting across the concept of being able to ‘hear’ but not fully understand or the time lag needed to integrate all of the pieces before comprehension occurs. This story is based on The Country Mouse and the City Mouse which is well known by many teachers.
Another approach is to provide a visual representation of a student’s estimated access to verbal instruction as identified with the Functional Listening Evaluation. A ready-made handout showing classroom directions imposed over 100 puzzle pieces is a very effective way of visually showing the impact of hearing loss.
Simulation of Listening in Varying Classroom Acoustic Conditions
Quick 4-slide Demonstration Be sure to include this 4-slide PowerPoint show with embedded audio files as you inservice teachers. You must show it as a PowerPoint slide show to be able to hear the various simulations. It simulates the effects of distance, high and low frequency listening and reverberation.

Simulations of Listening with a Cochlear Implant
Note: people who are born deaf and then get implanted at a young age and those who had normal hearing that progressed into deafness do not “hear” the way that the simulations below suggest. Given time, intervention, motivation and encouragement, the experience of listening through a cochlear implant results in the brain of the person adapting to the electronic input of a cochlear implant which often results in “hearing” with clarity that has been described as being similar to persons typical hearing. Cochlear implants do not result in, nor are they equal replacements for normal hearing. People who use cochlear implants will perceive sound at a loudness that is quieter than typical hearing and they will be significantly at a disadvantage when listening in noisy situations and at a distance. Of course vocabulary deficits, attention issues, and any area of educational delay will impact how well a person performs with a cochlear implant, regardless of how well or how clearly they “hear.”
- 1, 4, 8, 12 and 20 channel cochlear implant simulations for speech and music Source: The Hearing Journal published an article by Patrick M. Zurek and Joseph G. Desloge (of Sensimetrics Corporation) in its July 2007 issue entitled “Hearing loss and prosthesis simulation in audiology”.

- More sophisticated than some of the others, the AngelSim cochlear implant hearing loss simulator allows you to select speech processing strategies and then audio samples so that what you hear may be much more similar to a particular student’s experience than more generic CI simulations.
