Vintage Wood Encased Audiometer ▪︎ Audivox Model 9A ▪︎ Untested

Here's an interesting item that is very rarely seen, a vintage device that was used to test hearing levels and identify signs of hearing loss.. This is an Audivox model 9A portable, wood encased audiometer. The item has not been tested, because it takes a somewhat unusual battery type. As such, this is being sold strictly as-is, and priced as though it is not in working order. It would make a great piece of conversation starting decor.
