2. THE CONNECTIONS
BETWEEN SOUND &
EMOTION

3. SOME SOUNDS EVOKE UNIVERSAL
EMOTIONS
UCLA researchers have found that certain sounds are universally associated across
cultures with:
▪ Amusement
▪ Fear
▪ Anger
▪ Disgust
▪ Sadness
▪ Surprise

4. WHILE OTHER SOUNDS DEPEND
ON THE INDIVIDUAL

The sound of a vibrating cell
phone is perceived either as
annoying or exciting.

5. WHY DO EMOTIONAL
REACTIONS TO SOUND
VARY BY INDIVIDUAL?

6. LUND UNIVERSITY RESEARCH
Researchers 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.

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.

9. 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.

10. 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.

11. 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.

12. 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.

13. SOUND, EMOTION,
AND HEARING
LOSS

14. HEARING LOSS
When you lose your hearing, you not only lose the ability to
hear sounds…
You also lose the emotional impact associated with those
sounds.

on the faint sounds of
flowing water.

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

You increase your risk of injury
when you can’t hear alarms.

16. 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?
