waveforms that make up that complex pattern (the simpler waves used are sine waves) is
known as: - Answer✔Fourier analysis
The perceived sound differences between sounds with the same pitch but possessing different
higher harmonics is known as: - Answer✔Timbre
The difference in loudness and frequency distribution between the two ears is known as: -
Answer✔Interaural level difference
The cone of confusion is: - Answer✔A region of positions in space in which sounds create the
same interaural time and interaural level differences
What is the process by which a person isolates the sound of the air conditioner from other
sounds, such as the refrigerator, the television, the clock, and the lawn mower from next door?
