The Challenge

The Audiometry Department at the Royal United Hospital where we are based asked us to help create a product that would make it easier to test the hearing of very young children.

The Outcome

Our VRA works by stimulating the child patient (ages 2-6 years) with sound, using the animated toys as a reward for reacting. This makes the audiological testing easier to carry out, especially with ‘problematic’ subjects who have limited attention span. Children tend to cooperate for longer with a VRA system and provide more reactions. The system has proved very effective in obtaining accurate aided thresholds in hearing impaired children.

Our Design Process

We worked closely with audiometrists and children to design an effective and fun product that was clinically effective.

Benefits and Features

No tools are required to assemble the VRA system.
Assembly takes less than 30 minutes.

The CE Marked system is mains powered but operates only on low voltages, controlled by the handheld control switch unit.  No batteries are required.  It can be easily integrated with any audiometer or free field setup.

The VRA reward unit consists of two towers and a robust control unit, giving a choice on each side of three illuminated and animated toys. Any combination of the three can be activated by the easy to use controls.
