What problem is introduced when a hearing instrument is inserted into the concha and/or EAM in regards to resonance? How is it fixed> : Eliminates naturally occuring resonances of same-frequency signals, which must be fixed through the instrument for more natural-sounding amplification Frequency range to which the outer is is more sensitive : 2700 Hz to 5000 Hz Professionalism : The practice of an occupation with the highest standards of performance, accountability, and work ethic ...

An object hangs motionless from a spring. When the object is pulled down, the sum of the elastic potential energy of the spring and the gravitational potential energy of the object and Earth ANSWER: increases because the increase in elastic potential energy is greater than decrease in gravitational potential energy What kind of damping do you want shock absorbers to have? ANSWER: Critically damped Damping has two main effect which are: ANSWER: - It decreases the amplitude of oscillati...
