Airborne noise does more than annoy passengers — it actually changes the way food tastes. Recent demonstrations and sensory research show that loud, steady sounds like aircraft cabin noise can dampen sweet, salty and sour sensations while leaving umami intact. That selective effect can make tomato-rich dishes and other savory foods taste more pronounced when you're flying or sitting near a hum of white noise.
How noise reshapes taste: the umami exception
Studies into multisensory perception reveal that our auditory environment influences gustation. White noise and low-frequency hums reduce perceived intensity for sweet, salty and sour tastes. Umami — the savory flavor found in tomatoes, aged cheese, soy sauce and broths — appears resistant to that masking. The result: when other taste cues are muted by background noise, umami stands out more clearly.
From curling stones to tomatoes: trying your senses
You don't need a lab to experience sensory surprises. The interactive exhibition Senses Unwrapped at Coal Drops Yard in London’s King’s Cross invites visitors to test illusions first-hand. One exhibit demonstrates the size-weight illusion using three curling-stone replicas: the smallest often feels heaviest, even though scales show identical mass. Nearby, taste experiments let people compare how a noisy environment alters flavor perception — and why tomato juice or a ripe tomato can seem especially savory on a noisy plane.
Why this matters beyond curiosity
Understanding how sound shapes taste has practical implications. Airlines and food service designers can tailor menus and cabin acoustics to improve passenger satisfaction. Chefs and product developers can consider how ambient noise affects flavor balance in restaurants and public spaces. On a deeper level, these effects showcase how the brain integrates signals from eyes, ears and tongue to construct our sensory reality.
Try it yourself
Next time you eat or walk outside, pause for a moment. Close your eyes, listen to the background sounds, and notice how flavors shift. Simple experiments — tasting a tomato in a quiet room, then with steady background noise — reveal the subtle choreography of your senses.
'Our senses never act alone,' says Dr. Maya Singh, a sensory neuroscientist. 'Auditory cues can recalibrate taste perception, which is why the same food can feel different depending on where you eat it.' This interplay between sound and taste is a vivid reminder that perception is an active, multisensory process.
