- Audiometry tests only the frequencies important in human speech. I suspect
- this is because 1) most pathologic processes affect these frequencies and
- 2) no one is going to need a hearing aid to hear frequencies outside of this
- range. The rolloff at very high and very low frequencies is just not of much
- practical clinical significance. Those who are interested in knowing what
- their hearing range is need to use different equipment.
