Sound
a type of kinetic energy that refers to vibrations caused by a source. These
vibrations propagate as sound waves, travelling through the air and another
medium
-
Sound
the reception of such waves and their perception by the brain as an acoustical
meaning.
-
Acoustics
the science or study of sound, how it's created, its ability to travel within a
space, and the way it's managed.
-
Acoustics
the understanding of human hearing, and how everyone perceives sound
differently.
-
outer ear
the visible portion that collects vibrations in air pressure. Sound funnels into the
ear canal towards the eardrum.
-
middle ear
,starts at the eardrum, which is a membrane similar to a microphone. When
sound vibrations cause the eardrum to move, this action is transferred further
into the ear.
-
inner ear
consists of the cochlea, a spiral-shaped cavity that passes sound pressure
patterns to the brain as electrical nerve impulses, where they are interpreted as
sounds.
-
psychoacoustics
study of how humans perceive various sounds
-
Perceived listening
When the sound waves traveling through the air arrive at the ear. Within the ear
it is transformed into nerve pulses that travel to the brain.
3 multiple choice options
Critical listening
An engineering point of view for technical and physical aspects of sound,
music, frequency, range, and pitch. This helps in how sounds are blended
together and the ability to make adjustments.
3 multiple choice options
objective listening
Neutral and unbiased evaluation that takes facts and measurements into
consideration without bias
3 multiple choice options
compression
When the rise in sound level creates a positive pressure wave of air molecules
rarefaction
, When a drop in sound level creates less wave pressure.
Back and forth
The way air particles move
Length of a sound wave
Measured from crest to crest or trough to trough
Amplitude
Height of the wave
Sound waves are most similar to what natural phenomena?
Ripples - starts out strong but eventually disappates
Reflection
Sound Waves hitting a surface and bouncing off
Diffraction
Sound waves bending around an object
Refraction
change in the direction of waves as they pass through an object
Absorption
Some or all the waves are stopped within the material
Diffusion
Scattering of sound after reflecting off an irregular surface
Resonance
the vibration of an object or space at a certain frequency
Phase
The time-based difference of wave forms, either acoustical or electrical
What does the speed of sound depend on?
The medium through which it travels
