The plates are alive with the sound of food

posted by Jason Kottke   Jun 27, 2016

For an episode of food podcast Gastropod, hosts Cynthia Graber and Nicola Twilley consider how sound influences our perception of food and drink.

In this episode, we discover how manipulating sound can transform our experience of food and drink, making stale potato chips taste fresh, adding the sensation of cream to black coffee, or boosting the savory, peaty notes in whiskey.

One takeaway: don’t listen to the sound of breaking glass if you want to continue eating potato chips:

He recruited 200 volunteers willing to eat Pringles for science, and played them modified crunching sounds through headphones, some louder and some more muffled, as they ate. And he found that he could make a 15 percent difference in people’s perception of a stale chip’s freshness by playing them a louder crunch when they bit into it.

“The party version” of this trick, according to Spence, was developed by colleagues in the Netherlands and Japan. Volunteers were asked to crunch on chips in time with a metronome, while researchers played crunching sounds back, in perfect synchrony, through their headphones. All was well until the researchers replaced the crunching with the sound of breaking glass-and “people’s jaws just freeze up.”

The human brain is fascinating.
