Acoustic impedance)은 물질의 근본적 특성으로 어떤 물질의 음
향저항은 그 물질의 밀도에 그 물질내의 음파의 속도를 곱함으로서 얻어짐.
Z=ρ V Z=음향저항(Rayles)
ρ=밀도(g/㎤)
V=음파의 속도(㎝/sec)
초음파와 물질간의 상호작용
반사의 양은 또한 음속과 반사면 사이의 입사각에 의하여 결정되는데,

INT. PANEL VAN - DAY
Clarice Starling is dead, laid out in fatigues across a bench
in the back of a ratty, rattling undercover van. Three other
agents sit perched on the opposite bench, staring at her
lifeless body.
BURKE
How can she sleep at a time like this?
BRIGHAM
Shes on a jump-out squ
acoustic signature, a strange THRUMMING. The captain studies
the electronic position board, a graphic representation of the contours of
the steep-walled canyon, a symbol for the Montana, and converging with it, an
amorphous trace, representing the bogey.
CAPTAIN
What the hell is it?
EXEC
Ill tell you what its not, its not one of
ours.
BARNES
Sir! Contact changing heading to two-one-four,
diving.
