hearing science exam #2

The process of “breaking down” a complex sound to show all of the frequencies that it contains is called...

(a)  

• The lowest frequency present in a complex sound

(a)  

Integer multiples of the fundamental frequency

(a)  

•  is often considered a sound containing every frequency in a certain range (i.e, between 2 numbers)

• aperiodic

(a)  

• The frequency range, from the lowest frequency included, to the highest frequency included.

(a)  

• The relative (a)   is indicated by the “color” of the noise 

• Doubling or half of the frequency 

  • Up one ------ means multiplying the frequency by 2 

  • Down one ------ means dividing frequency by 2 

(a)  

• commonly affect the frequency 

• Describes by the cut-off frequency 

(a)  

• The frequency where the amplitude starts to decrease

  • Ex. in pink noise, the cut-off starts immediately, at the lowest frequency

  • Can occur anywhere within the bandwidth 

(a)  

• Frequency gets through (transmitted) 

• 1 cut-off frequency 

• Everything higher than the frequency passes through

(a)
