Question

Emergency medical technicians are sometimes told to speak in the lower voice when responding to older patients, why is this?

A. lower voice sound sound more authoritative
B. The eardrums of older people are heavier and do not vibrate as well to high voices
C. conductive hearing loss typically begins in high frequency hair cells
D. lower frequencies require higher sound pressures according to the Fletcher Munson curve
E. sensorineural hearing loss typically begins in high frequency hair cells

Answer 1

Option E

sensorineural hearing loss typically begins in high-frequency hair cells

Step-by-step explanation:

In presbycusis, most old people cannot hear the high-frequency sounds, because of some loss of hair cells in their cochlea. unlike some other vertebrates like fishes and reptiles, these hair cells can be re-generated. However, in Humans, they cannot be.

As a result of these sounds that have higher pitches such as the buzzing of a mosquito, are muffled to them. Therefore, talking in a frequency is necessary, as this will aid the old people hear the medical technicians better.
