ASLP 3030: Exam 1 2025 Questions and
Answers
Acoustics - --CORRECT ANSWER--Acoustics refers to the scientific study of
sound waves in terms of how it is generated and
transmitted.
Why do we study wave motions and oscillation in acoustics? - --CORRECT
ANSWER--We study the properties of wave motion and oscillation in order to
have a
precise understanding of sound waves and their characteristics.
What are the essential properties of sound source and sound medium? - --
CORRECT ANSWER--Mass and Elasticity
Sound source and Sound Medium are (.....) of eachother - --CORRECT
ANSWER--Independent
The frequency and period of is determined by the properties of? - --CORRECT
ANSWER--The sound source

, The speed of transmission is determined by the properties of? - --CORRECT
ANSWER--The sound medium
How do sound waves propagate? - --CORRECT ANSWER--When set into
motion, air molecules oscillate back and forth about their equilibrium
positions, causing adjacent air molecules to move closer together and air pressure
to
increase (condensation) and then move further apart causing air pressure to
decrease
(rarefaction). It is the disturbance which travels, not the individual air particles in
the
medium. Sound waves propagate in a spherical, longitudinal fashion.
Amplitude - --CORRECT ANSWER--the displacement of particles during
vibration. related to sound pressure and intensity
Frequency - --CORRECT ANSWER--the number of cycles per second
Period - --CORRECT ANSWER--the amount of time to complete one cycle of
vibration
What happens to the amplitude of a sound as it propagates? - --CORRECT
ANSWER--The sound pressure changes in inverse proportion to the square of the
