Decibels (dB) as a Measure of Sound Intensity
Decibels (dB) are a logarithmic unit used to measure sound intensity, which corresponds to perceived loudness. The scale is used to represent a wide range of sounds, from the low end of human hearing, such as a whisper or rustling leaves, to extremely loud noises like a jet plane taking off, which is near the threshold for pain at approximately 130 dB.

Encoding pitch information
An audio engineer is editing a recording of a flute. They determine that the sound needs to be perceived as both higher in pitch and louder. Which of the following adjustments to the sound wave's physical properties would accomplish this?
An audio engineer is comparing two distinct sound waves. Sound Wave 1 has a high frequency and a low amplitude. Sound Wave 2 has a low frequency and a high amplitude. How would a listener most likely perceive the difference between the sound produced by Wave 1 and the sound produced by Wave 2?

An audio engineer at a concert increases the sound level from 70 dB to 90 dB. Which statement best analyzes the change in the sound's physical intensity and how it is perceived by the audience?
A sound increases in intensity from 30 dB to 50 dB. A second, much louder sound increases from 90 dB to 110 dB. How does the perceived change in loudness for the first sound compare to the perceived change for the second sound?
