Frequency - Lesson Content

Definition Measuring Frequency vs. Pitch

Human Hearing Range Frequency Response See Examples

Listen to Examples


4/14

Definition of Frequency

Periodic vibration or the number of cyclesper unit of time, audible to the averagehuman

Property of sound that most determinespitch


5/14

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


6/14

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


7/14

Human Hearing Range

Roughly: 20 to 20,000 Hz

Greatly influenced by environmental

factors

The perception of higher range tends to

decrease with age


8/14

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


9/14

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)


10/14

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 .
