Definition of Frequency
Periodic vibration or the number of cyclesper unit of time, audible to the averagehuman
Property of sound that most determinespitch

Measuring
For convenience, frequency is most oftenmeasured in cycles per second (cps) or theinterchangeable Hertz (Hz) (60 cps = 60
Hz), named after the 19th C. physicist
1000 Hz is often referred to as 1 kHz
(kilohertz) or simply '1k' in studioparlance

Frequency vs. Pitch
The perceived pitch of a sound is ourear/mind's subjective interpretation of itsfrequency
Pitch - we hear low to high sounds Frequency - what equipments measure in
cps (Hz)
More Hz - higher sound Fewer Hz - lower sound

Human Hearing Range
Roughly: 20 to 20,000 Hz
Greatly influenced by environmental
factors
The perception of higher range tends to
decrease with age

Human Hearing Range
Below 20 Hz - felt rather than heard,assuming the amplitude of the vibration isgreat enough
Above 20,000 Hz - sometimes sensed byyoung people
High frequencies are the first to be
affected by hearing loss due to age and/orprolonged exposure to extreme noise

Frequency Response
We don't hear equally across the entirehearing range
He hear less as we go the lower and higher
end of frequency range Human ears as well as audio equipments
act as EQ (set of frequency filters)

See Examples
Low Frequency Higher Frequency* We can't hear these frequencies, since they are below 20 Hz.

Personal Reflections
I wanted to make my lesson simple, clear and brief.Really like the thought:Brevity is respect for another's time.
If there is anything I missed or could have explainedbetter, I would like to hear your thoughts. :) Thanks. Since I wanted to add short audio examples to my
google presentation, I had problems to find a simpleservice for sharing audio files. Finally, liked theShoutomatic .
