I am seriously interested in coming up with an estimate, the world-wide
growth rate of hearing aids using #10 batteries.

How might this figure be calculated?  A current starting point, i.e. number
of units in use today?  Projected growth rate (considering the 78 million or
so baby-boomers now in play)?

Kind Regards and Thank You,
