2. Selective Enhancements: Outer Ear

3. Middle Ear Impedance Mismatch
AREA RATIO
Area of the tympanic membrane much larger than round window (25 dB)
LEVER RATIO
Length of long arm of malleus much longer than long arm of incus (2 dB)
BUCKLING ACTION
Force transmitted from center of tympanic membrane (i.e., TM doesn't move as plate) (4-6 dB)
