Exam 1 Review Part 2
1) Describe how the middle ear impedance matcher works. (2 ways)
1- larger than stapes. force is concentrated
thus increasing pressure over oval window
2- lever action:incus shorter than mallus thus increase
2) What are the various fo
Here is a review if you are interested. I will post the answers to the problems at the end of this
review, but not for the define these questions.
1. Audiologists were not allowed to dispense hearing aids until?
2. What are the three requirements
The following equation represents how to
mathematically solve for speed and distance
= wavelength x frequency
Stiffness- the stiffer an object, the more
elasticity it has. Vibrates
greater force = greater amplitude
magnitude of sound /
how far molecules are moving
* ! Distance)a)mass)moves from its point of rest
what is sound?
use it to communicate, enjoy, alerting, to be aware of our surroundings
the physical properties (vibrating energy)
generated by a source that send air pressure waves
equal to energy - energy comes from pressure waves
