What are the 3 bones of the middle ear?
Hammer, anvil & stirrup
What are the two functions of the ear
perception of hearing and balance
What is the most complex part of the ear?
What is another name for periodic vibrations in atmospheric pressure
sound pressure waves
What is the high pressure part called
What is the low part called
What am I doing?
What are the 2 parts together called?
I cycle of atmospheric pressure
what are the characteristics of a waveform
amplitude, frequency, velocity, wavelength, phase, harmonic content and envelope.
what is the range of human hearing
20 Hz to 20kHz
what is another term for cycles per seconds
what units of measure do we use to measure
dB or decibels
what is outboard equipment
anything not connected to the console
Name the 5 domains of outboard gear?
Tonal, Time, Dynamic, Frequency and Spatial
What is a parameter
something that can be adjusted or controlled
outboard gear can be broken down into to 2 groups what are they?
Effects, Signal processors
What do you call the place all inputs and outputs are connected?
the patch bay
What are the two main rules?
Never connect an output to an output
Any line level output can be connected to any line level input, other than its own, if it is upstream in signal flow.
what is a patch point
Any individual jack that allows us to access our signal
what is an insert point?
Any pair of jacks that allows us to add an additional component to signal flow.
what domain has devices that affect harmonic content
What do we call passive tone control
what are the parameters of filters
cutoff frequency and slope
what type of filters reduces lows
High pass filter
What kind of filter reduces highs?
low pass filter
what does a band pass filter do?
reduce lows and highs.
what do we call a very narrow band pass filter
a notch filter
what is cutoff frequency?
Any frequency that is reduced −3dB from normal.
How is slope measured?
dB’s per octaves
What is a series of notch filters called?
a comb filter
what do we call it when we automatically sweep the center frequencies up & down?
sweeping comb filter
What are the parameters of that device?
speed and depth
what do we call an active tone control
A tone control with an amp (an EQ for example)
what are the two types of equalizers?
shelving and peaking
what kind of equalizers boost and cuts a range of frequencies around a center frequency?
what kind of eq affects all frequencies above or below the selected frequency equally?
Name the 3 parameters of eq
cut/boost, frequency, bandwidth or q
