Speech Science & Acoustics Flashcards
When sound waves move from one medium to another it causes a BENDING of the sound wave due to change in its speed of propagation. This phenomenon is known as a. refraction
b. reflection
c. compression
d. rarefaction
e. sinusoidal motion
REFRACTION!
Acoustical , mechanical, or electrical resistance to motion or sound transmission is called:
a. impedance
b. admittance
c. immitance
d. velocity
e. reflection
IMPEDANCE
The back and forth movement of particles when the movement is symmetrical and periodic is called…
SIMPLE HARMONIC MOTION
The thinning of air molecules when the vibrating object returns to equilibrium.
RAREFACTION!
When a phase sound in which the vibratory movement of an object increases DENSITY of air molecules because they are compressed in known as
COMPRESSION OR CONDENSATION!
What is an octave?
Indication of the interval between two frequencies
