I do not know if the Fletcher-Munson curves were used when the signal sources were designed. They show normal hearing loss at low frequencies and at low levels that none of us have so they were probably included.
Today I will return the first demo hearing aids worth $5500.00 (!!) because they sound awful and are larger than the $3500.00 demo ones I have now.
I did the hearing test again today that I did yesterday with my computer speakers and the Phonak hearing aids. The results today are exactly the same as yesterday.
