Infrasound Answer: Any sound that is less than audible sound.
Infrasound Answer: Any sound that is less than audible sound.
Mechanical energy Answer: Energy transmitted by pressure waves in a medium.
Sound wave Answer: A wave that can travel through air, water, and steel, but not
through a vacuum.
Properties of sound sources Answer: They cause vibrations in the medium.
Speed of sound Answer: Depends on wavelength, frequency, medium, and amplitude.
Regions of compression Answer: Regions in a sound wave where the pressure is
higher than normal.
Reflection Answer: The redirection of a portion of the sound beam back to the
transducer.
Longitudinal wave Answer: A type of sound wave that can propagate through soft
tissue.
Echo Answer: An echo caused by the bending of the sound beam.
Longitudinal wave definition Answer: A wave in which the oscillating energy is in the
direction of the wave motion.
Lowest level of concentration Answer: Called rarefaction.
Wavelength and frequency relationship Answer: As the frequency of the wave
increases, the wavelength will decrease.
Time for one cycle of a wave Answer: Referred to as the period.
Specular reflection Answer: Occurs at a large and smooth tissue interface.
Stiffness of a medium Answer: The opposite of compressibility.
Absorption with frequency Answer: More absorption takes place when using a
transducer with higher frequency.

, Intensity and power relationship Answer: As the power of the beam increases, intensity
will increase.
Speed of sound arrangement Answer: Air, water, tissue, bone.
Ultrasound absorption Answer: It is part of attenuation.
Density and speed of sound Answer: If the density of a material increases, the speed
of sound will increase.
Amplitude and intensity relationship Answer: By doubling the amplitude, the intensity
will increase by four.
Acoustic variable Answer: Amplitude is not classified as an acoustic variable.
Units of intensity Answer: Intensity has units of W/cm².
Reduction of intensity Answer: The reduction of intensity of the ultrasound beam as it
travels through the tissue is known as attenuation.
absorption Answer: The gradual loss of energy as it travels through tissue.
attenuation Answer: The weakening of sound in a medium.
scatter Answer: The redirection of sound waves in multiple directions.
Piezoelectric effect Answer: The property of certain materials to create a voltage when
they are mechanically deformed.
acoustic impedance Answer: A measure of how much resistance an acoustic wave
encounters as it travels through a medium.
hyperechoic Answer: A region that has elevated echogenicity.
damping material Answer: Material in a transducer that reduces the pulse length.
transducer Answer: A device that converts one form of energy into another.
linear segmental array Answer: A type of transducer that produces a rectangular
image.
bandwidth Answer: The range of frequencies over which a transducer operates.
Curie temperature Answer: The temperature at which a material loses its piezoelectric
properties.
frequency Answer: The number of cycles per second of a sound wave.
