What describes the Doppler effect?
The Doppler effect, or Doppler shift, describes the changes in frequency of any kind of sound or light wave produced by a moving source with respect to an observer. Waves emitted by an object traveling toward an observer get compressed — prompting a higher frequency — as the source approaches the observer.

This condition is not caused by hearing loss, or any type of hearing disorder. Phonophobia is a specific phobia.
How does noise affect stress?
Noise triggers a stress response in the amygdala, a region of the brainstem. Our amygdala learns, over time, what sounds might signal impending danger. When one is detected, the amygdala triggers a release of cortisol (a stress hormone) and an involuntary startle reaction.
What makes you sensitive to noise?
