Background noise affects taste of foods 背景聲音影響食物味道


The level of background noise affects both the intensity of flavour and the perceived crunchiness of foods, researchers have found. Blindfolded diners assessed the sweetness, saltiness, and crunchiness, as well as overall flavour, of foods as they were played white noise. While louder noise reduced the reported sweetness or saltiness, it increased the measure of crunch.
It may go some way to explaining why airline food is notoriously bland - a phenomenon that drives airline catering companies to heavily season their foods.
"There’s a general opinion that aeroplane foods aren’t fantastic," said Andy Woods, a researcher from Unilever’s laboratories and the University of Manchester."I’m sure airlines do their best - and given that, we wondered if there are other reasons why the food would not be so good. One thought was perhaps the background noise has some impact," he told BBC News.
In a comparatively small study, 48 participants were fed sweet foods such as biscuits or salty ones such as crisps, while listening to silence or noise through headphones. In noisier settings, foods were rated less salty or sweet than they were in the absence of background noise, but were rated to be more crunchy.
