6 ways your brain transforms sound into emotion

▪ Amusement
▪ Fear

The sound of a vibrating cell phone is perceived either as annoying or exciting.
LUND UNIVERSITY RESEARCHResearchers from Sweden’s Lund University identified 6 psychological mechanisms by which sound evokes emotions and helps to explain why the reaction is sometimes universal and sometimes dependent on the person.
The 6 mechanisms:
1. Brainstem Reflex
2. Evaluative Conditioning
3. Emotional Contagion
4. Visual Imagery
5. Episodic Memory
6. Music Expectancy

When you hear a loud, unexpected, abrupt sound, you are immediately compelled to investigate.
This reaction is hard-wired into your brain to alert you to immediately respond to potentially dangerous or important sounds.

EVALUATIVE CONDITIONING

A song played during your wedding day may bring feelings of joy…

While the same song heard during a funeral will produce the opposite feelings of sadness.
EMOTIONAL CONTAGION

Research in the 1990s discovered “mirror neurons” that activate in our brains when we watch someone perform an action.
That’s why it’s hard to not smile and laugh when you see others doing the same.
VISUAL IMAGERY

Sounds can evoke images which in turn evoke emotions.
For example, do you enjoy listening to the sounds of nature?
Try listening to an audio recording of waves crashing and NOT visualizing yourself lounging at the beach.
EPISODIC MEMORY
Sound can trigger both good and bad memories, depending on how the sound was paired with a single event.
That’s why the sound of lightning can create fear and anxiety in those suffering from post-traumatic-stress-disorder from combat experience, for example.

MUSIC EXPECTANCY

Music is nothing more than a random assortment of sounds…
Music is emotionally appealing only because your brain imposes order and structure to the sounds…
Your expectations about rhythm and melody provide this order and structure, and therefore your emotional reaction.
HEARING LOSSWhen you lose your hearing, you not only lose the ability to hear sounds…
You also lose the emotional impact associated with those sounds.

Music loses its emotional punch when you can’t hear certain instruments.

You increase your risk of injury when you can’t hear alarms.
TREATING HEARING LOSS
The bottom line: hearing is more important to our lives—and to our emotional lives—than we probably realize. It also means that treating your hearing loss will probably have a greater impact than you realize, too.
What are some of your favorite sounds? What emotions do they evoke?
