societal and/or familial expectations, among others.

Ethical always equals legal, but... - ans -......legal does not always equal ethical.
Unethical does not always equal illegal, but.... - ans -.....illegal always equals unethical.
Acoustics - ans -__________ is a branch of physics specializing in sound.
Sound - ans -__________ is a form of energy which originates when a force creates a
vibration in the molecules of a solid, liquid, or gas.
Sound energy travels by... - ans -this type of energy travels by waves that expand in
spheres in all directions.
Compression - ans -_________ is when some of the air molecules are pushed together
when a sound wave travels. It is more dense than at rest. This is known as...
Rarefaction - ans -___________ is when a sound wave travels, some molecules are
less dense and spread farther apart than normal
Pure Tone - ans -__________ is produced by simple repeated alternations of
compression and rarefaction.
Sine Wave - ans -_________ is a graphic representation of a pure tone.
When representing a sine wave on a graph the vertical axis shows _______1.________
and the horizontal shows _______2._____________. - ans -1. amplitude of the wave
(power increases amplitude)
2. indicated the time (period)
Frequency - ans -_________ is the number of complete compression/rarefaction cycles
per second.
The unit for frequency is.. - ans -..... Hertz (Hz) or cycles per second.
Period - ans -_____________ is the time required for one complete cycle of
compression and rarefaction.
Amplitude - ans -_________ graphically describes the intensity of the energy of a
vibrating body. It is usually expressed in decibels (dB)
Intensity is usually expressed in.. - ans -_____________ is usually expressed in
decibels (dB)
, Wavelength - ans -_________ is the distance between one wave crest and trough to the
next.
the wavelength of a ___1___ frequency sound is shorter than the wavelength of a
_____2____ frequency sound. - ans -1. high
2. low
Additional: a high frequency pure tone with a shorter wavelength will have more cycles
tin the same period than a low frequency tone with a long wavelength.
Phase - ans -________ is a term used to describe the position in the cycle of one sound
wave relative to another.
At sea level, sound waves travel in the air at about __________ feet per second or
more than 760 miles per hour. - ans -they travel at 1100 feet per second.
Sound travels faster as the density of the medium increases regardless of the
frequency. Therefore, sound travels about 4x faster through __1___, and 15x faster
through ___2____, than through ___3____. - ans -1. water 2. steel 3. air
Resonance - ans -________ is the natural tendency for an object to vibrate with greater
amplitude at one frequency that at others when a driving force is applied.
Resonant frequency - ans -_______________ is the frequency with the greatest
amplitude
Reflection - ans -_____________ is a characteristic of environment. flat hard surfaces
reflect sound to a greater degree and uneven or soft surfaces.
Reverberations - ans -_______________ are sounds that are reflected from the walls,
floor or ceiling of a room. They man persist after the sound source ceases to vibrate.
Echo - ans -__________ is a sound reflection heard separately from the original sound.
Absorption - ans -______________ is the opposite of reflection. Drapes, carpet and
upholstered furniture absorb sound waves and reduce reflections and echoes.
Complex wave - ans -_________ is the acoustical combination of several different pure
tones presented at the same time.
Sound Pressure. - ans -__________ is the deviation from the ambient atmospheric
pressure caused by a sound wave. Pressure is generated whenever a force is applied
to a surface area like the TM.
The commonly used units for sound pressure measurements are.... - ans -.......... are
dynes per square centimeter (dynes/cm^2) or micro Pascals.
