Deep Voices And Low Pitches Make Products Seem Larger

Why does that sandwich look so big in the ad? It may not be because of what you see, but because of what you hear. Researchers have discovered a huge association between pitch and perception.

The Deeper the Voice, the Bigger the Sandwich

A 2017 study published in the Journal of Marketing Research showed how consumers associate a lower pitch—whether it's in a deep voice or in bass-heavy music—with a larger product size. In the study, researchers from the Georgia Institute of Technology and Vanderbilt University conducted a series of experiments, including one where participants listened to a radio advertisement for a new sandwich, according to a press release. Researchers altered the pitch of the voice on that advertisement to be higher or lower and then asked participants how large the sandwich was. Those who had heard the lower-pitched voice believed the sandwich was significantly larger than those who heard the higher-pitched voice. Another study showed the same association with music: participants who heard lower-pitched music believed a laptop in an advertisement was larger than those who heard higher-pitched music.

"There is meaning in sound that transcends language," write the researchers in the study, as BGR reports. "Structural differences in the sound of a spokesperson's voice or a piece of background music can influence a consumer's perception of product attributes."

A New Tool in the Advertisers' Kit

As The Science Times reports, researchers hope that their findings could help advertisers unlock the secrets of sensory marketing. Ad agencies could take a more scientific approach to shaping consumers' perception. Just one more way that the science of selling is taking over the world.
