Choosing the Right VRA System for Your Clinic

​

Not all VRA systems are designed the same.  As pediatric hearing evaluations have evolved, the expectations for VRA equipment have changed, as well. Clinics now look for systems that are reliable, flexible, and easy to use while supporting consistent patient responses.

​

Here are the key factors to consider when selecting a VRA system.

​

1. Reliability and Timing

A VRA system must respond instantly when the clinician triggers a reinforcer. Any lag or delay makes the test harder and can disrupt the child’s attention.  Software driven systems tend to offer faster activation times compared to older mechanical VRA boxes.  For instance, Flex VRA utilizes a paired zoned 433 MHz radio frequency wireless transmission protocol to send signal from the remote control to the reinforcer.  This means that the lag time between button press to activation would be similar to that of a lag time of a wireless keyboard to your computer...instantaneous.  Moreover, because each system's transmission is zoned between paired reinforcers, there is no overlap from other systems or interference from any higher frequency RF signals.

​

2. Quality of Visual Reinforcers

Children respond best to bright, engaging, but not overstimulating content. Look for a VRA system that allows you to customize content and adjust how exciting the reinforcer should present. Features like House Rules in Flex VRA let you control how the center monitor behaves so you get clearer head turns, and more focus on the left and right reinforcers.

 

3. Integration With Audiology Equipment

The best VRA equipment connects smoothly with your audiometer, remote, or clinic workflow. Consider whether the system supports:
• Remote control activation
• Audiometer integration
• PC or software-based triggering

Seamless integration allows clinicians to stay focused on the patient instead of the equipment.  And Flex VRA includes all three of those options with every Flex VRA shipped at no extra cost.

​

4. Durability and Build Quality

VRA equipment is used daily in pediatric settings. Look for a system designed to withstand constant use, movement between rooms, and long clinical schedules.

​

5. Versatility and Future Features

Clinics benefit from VRA systems that grow with them. Software based systems often release updates, new reinforcers, and feature improvements that extend the life of the system without requiring new hardware.

​

6. Support and Service

Make sure the company behind your VRA system offers reliable support. Pediatric audiology depends on smooth daily operation, so access to fast assistance matters.

By evaluating these factors, clinics can choose VRA equipment that improves workflow, supports accurate Visual Reinforcement Audiometry, and creates a better experience for both the child and family.
