We saw, in our discussion of the ear’s response to any tone, that there ensued a short period after stimulation during which the sensitivity had not returned completely to normal. For stronger tones this period of reduced sensitivity is even longer. Thus our concern focuses on whether this failure to return quickly to normal sensitivity indicates an increasing danger that with enough stimulation some permanent impairment will result.
