Thanks for the explination.
My son by the way could hear up to 24KHz.

I would just use a normal microphone and speaker but calibrate them to compensate for the drop off in sensitivity at these higher frequencies. If you can plot the curve then you could match that to the opposite function with an active filter, and produce a flat response.
