Q

how many octaves is normal for young adults?

A

3

17
Q

what happens to the MPFR in older adults?

A

it decreases because the VFs become less flexible

18
Q

MPFR is also reduced in individuals who are…

A

unhealthy!

19
Q

MPFR is useful in reflecting

A

physiological limits of voice, physical condition of vocal mechanism, and basic vocal ability

20
Q

what is the amplitude variable that response to MPFR?

A

dynamic range

21
Q

what is the dynamic range?

A

the range of the softest to loudest sound one can produce

22
Q

what is the avg amplitude of normal conversational speech?

A

55-75 dB

23
Q

does dynamic range include whispers?

A

NOOOOO!!!! VFs much be vibrating
