Questions With Correct
Solutions!!
acoustics - ANSWER-A branch of physics devoted to the study of sound: its production, transmission,
and effects.
dynamics - ANSWER-The study of the forces that result in the movement of objects.
kinematics - ANSWER-The study of motion, the positions, velocities, and acceleration of body parts.
_________ is concerned with movements without regard to the forces that cause the movements.
psychoacoustics - ANSWER-An interdisciplinary field of psychology and acoustics that addresses the
relationship between the physical properties of a phenomenon and our perception of these
properties.
voice science - ANSWER-The study of the acoustics, aerodynamics, and physiology of voice
production, with specific focus upon laryngeal dynamics and vocal tract interaction.
acoustic resonator - ANSWER-A partially or completely enclosed container, in which the air inside is
set into vibration.
amplitude - ANSWER-The magnitude of oscillation.
antinode - ANSWER-The area of the largest amplitude of vibration of a sound wave.
aperiodic - ANSWER-Irregular sound wave, having no definite pattern of repeating cycles.
boundary - ANSWER-The interface between two mediums, such as the vocal tract and the
surrounding air.
, complex sound - ANSWER-A sound wave consisting of two or more pure sounds.
compression - ANSWER-The collisions of air molecules result in regions of increase density called
________. _________ are regions of high air pressure.
constructive interference - ANSWER-An area of rarefaction of a wave meets the area of rarefaction of
another wave, the net effect of which is to amplify the rarefaction. Or an area of compression of a
wave meets the area of compression of another wave, the net effect of which is to amplify the
compression.
continuous spectrum - ANSWER-A spectrum that contains energy at all frequencies.
decibel scale - ANSWER-A logarithmic scaled used to measure intensity.
speech production - ANSWER-The generation of airflow and the creation of air pressures by the
displacement of bodily structures which, taken together, cause the disturbances of air that constitute
phonemes, the smallest meaningful units of sound.
speech science - ANSWER-The study of the acoustics, aerodynamics, and physiology of the
production, transmission, and effects of speech. When used in the general sense, ___________
includes voice science.
destructive interference - ANSWER-A wave interferes with another wave such that a compression of
one wave meets a rarefaction of the other wave, and the net effect is to decrease the overall energy.
diffraction - ANSWER-The sound wave bends around an obstacle without going through the
boundary.
displacement force - ANSWER-Force that causes a mass to be moved away from equilibrium.
elasticity - ANSWER-The ability of an object to spring back to its resting shape when deforming forces
are removed.
