Which of the following best describes pink noise, as used in audio engineering?
Understand the Problem
The question asks for the best description of pink noise in audio engineering. Pink noise is a type of signal or noise with a frequency spectrum such that the power spectral density is inversely proportional to the frequency. This means that equal energy occurs in each octave.
Answer
Pink noise has equal energy per octave and is used for audio testing and tuning.
In audio engineering, pink noise is a type of noise signal having equal energy per octave, which makes it useful for testing and tuning audio systems because it closely matches how humans hear.
Answer for screen readers
In audio engineering, pink noise is a type of noise signal having equal energy per octave, which makes it useful for testing and tuning audio systems because it closely matches how humans hear.
More Information
Pink noise sounds like a waterfall. It is used extensively in audio engineering, primarily for equalizing audio systems and testing audio equipment.
Tips
A common mistake is thinking pink noise is the same as white noise. Pink noise has equal energy per octave, whereas white noise has equal power per hertz.
