3Visual Reinforcement Audiometry (VRA)
VRA is a tool that can help keeping young patients stay focused during audiometric or other procedures by
giving them a visual reward. The test is performed by an audiometer or another medical device. By using vis-
ual reinforcement, the child is trained to move their head to either side and indicate that they have heard the
sound, thus giving the clinician an indication of the hearing level.
VRA is often done in a free field environment when it is infants/very young toddlers, and it is therefore not
possible to determine which side the sound was heard at, at a specific sound level. If the child accepts it,
headphones or foam tips with inserts can be used to make an ear specific audiometry.
In the VRA setup there are usually two screens, one on each side of the child. When the clinician is present-
ing a sound, the child is prompted to turn its head towards the sound. This can require some training at first.
When the child moves its head towards the sound heard, the screen is activated by the operator, and an ani-
mation or image is presented as a reward.
By using the VRA setup it makes it more fun for the young child to participate in the examination and it does
not seem so intimidating getting a hearing test, when cartoons and toys are used.

Setup
Screens
The VRA Screen PC can have up to three screens connected.
Connect two of the screens directly with HDMI and the last with the HDMI to DP adaptor, as there are
only two HDMI ports in the VRA PC. It does not matter what screen is connected to which port, as it is
possible to choose the screens position in the settings screen.
Start-up
1. Press the Power button on the VRA Screen PC. A default playlist is preloaded on the system.
The VRA screens will always start-up with black screens and the only indication for the system be-
ing turned on, is the light in the power button on the PC. Wait for 30 seconds. The system is now
ready for use.
2. The mouse is now used to control the VRA system.
Right click: Shows image or video on the right screen.
Left click: Shows image or video on the left screen.
Wheel click: Show image or video on the center screen. When having more
playlists on the VRA PC, it is possible to switch between them by using the
mouse wheel. A small indication of the seelcted playlist will appear on screen.
Three turns upwards: shifts to next playlist. Three turn downwards: shift
the image or video to previous one. This can be useful in case a reward really
caught the attention of the child and you want to reuse it once again.
Pressing the respective key for the screen while the reward is on will result in
the reward disapearing immediately.

shown on screen, which image should appear on what playlist, should a single video or image be
shown multiple times in a row etc.
