Should.The sound that human ear is heard, depending on the energy that cochlea is received, the energy is subject to the shadow of different physical quantities in transmittance process
Ring, can be represented by below equation：
P=∫ ∫Sα·f(a,R)·L·ds (11)

That is B points are not contacted with skin.People's face skin shows the impedance to sound at various pressures from hypodermis and response is different.
The big position unit area impedance of pressure is little, and the filtering characteristic for having deflection high pass to sound wave, the little position unit area impedance of pressure is big, has deflection low
Logical filtering characteristic.Impedance operator L at each position of contact surface 1601 is different, and according to formula (11), different parts are transmitted to sound
When frequency response it is different, the effect that sound is transmitted by Full connected face is equivalent to the summation that each position sound is transmitted, final sound
Sound forms smooth frequency response curve when being delivered to brain, it is to avoid have in low frequency or high frequency the appearance of too high resonance peak,
So as to obtain preferable frequency response in whole audio bandwidth.Likewise, the material and thickness of contact surface 1601 also can be to sound
Transmission produce impact, so as to affect acoustical quality.For example, during contact surface made of soft, the sound wave transmission effect of low-frequency range
It is better than the sound wave transmission of high-frequency range, when contact surface material is harder, the sound wave transmission effect of high-frequency range is better than low-frequency range
Sound wave is transmitted.
