Speech Science Test 1 Flashcards
(33 cards)
Definition of Acoustics
the study of the physics of sound
Definition of Kinematics
the study of motion
Definition of Dynamics
the study of the forces that causes movement
Definition of Psychoacoustics
the study of the relationship between physical properties and our perception. of those properties
Definition of Speech Production
the generation of airflow and the creation of air pressures by the displacement or movement of bodily structures that results in the production of linguistically meaningful sound.
Definition of Voice Production
the generation of sound waves by vibration of the vocal folds which are then modified by vocal tract (don’t need to be linguistically meaningful)
What does MKS stand for?
M-distance in Meters
Volume in Liters
K-mass in Kilograms
S-time in Seconds
Definition of force
a push or pull on an object; movement of speech achieved by management of forces
Definition of speed
distance covered in a specified period of time (speech measured in syllables/minute)
Definition of velocity
the speed of something with an added notation of the direction of movement; has research purposes
ex. downward movement of the jaw
Definition of acceleration
the increase in velocity in a period of time traveled (ft per second squared)
Definition of deceleration
negative change in velocity
Newton’s first law of motion
a moving object will continue moving in a straight line at a constant speed, a stationary object will remain at rest unless acted upon by an outside force (aka the law of intertia)
Law of Inertia
an object’s tendency to resist change in motion
Newton’s Second Law of Motion
when a force acts upon an object, the object accelerates in the same direction of the force
Acceleration is ________ proportional to the net force and _________ proportional to the mass of the object
directly; inversely
the greater the mass, the ______ the acceleration and the less the mass, the _______ the acceleration
slower; faster
What is the unit of force?
Newton (N)
Newtons third law of motion
for every action of force there is an equal and opposite reaction or force
momentum
the strength or force that something has when it is moving, the product of mass x velocity
definition of work
the measure of force exerted over some distance, the transfer of energy that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement
What is the unit of measurement for work?
Joule
definition of joule
amount of work done when exactly one newton of force through distance of one meter
definition of energy
the ability to do work
