Tympanic membrane eardrum - Study guides, Class notes & Summaries

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 ...
