Restaurant Noise Can Alter Food Taste

A noisy restaurant can distract you from your dinner conversation. But all that clatter may also drown out the taste of your food, making it more bland. That's according to a study in the journal Food Quality and Preference. [A.T. Woods et al, Effect of background noise on food perception]
餐廳里吵吵鬧鬧的不僅會(huì)妨礙人們交談，還會(huì)讓人覺得餐桌上的食物淡而無味。這是刊登在《食品質(zhì)量與選擇》期刊上的一項(xiàng)發(fā)現(xiàn)。

Researchers recruited 48 college students, and fitted them with headphones playing either loud white noise, soft white noise, or nothing at all. Then the participants closed their eyes and chomped on snack foods like Pringles and cookies.
研究人員找來48名大學(xué)生，讓他們帶上耳機(jī)，一部分人聽的是嘈雜的白噪聲，一部分人聽的是舒緩的白噪聲，余下的人的耳機(jī)里什么也沒放。然后讓他們閉上眼睛，吃吃薯片、甜餅干什么的。

Turns out the students listening to blaring static rated the chips as less salty and the cookies as less sweet—even though they were tasting the same foods as the other groups.
結(jié)果發(fā)現(xiàn)，聽嘈雜白噪聲的那組學(xué)生覺得薯片不夠咸，餅干不夠甜，其實(shí)他們和另外兩組吃的是完全一樣的東西。

Previous studies have shown that sound can interfere with how the brain processes smell; the researchers say the same could be true for taste. Or, loud noise could simply divert attention from the food's flavor.
之前就有研究表明，聲音會(huì)干擾大腦處理嗅覺信號(hào)，研究人員認(rèn)為味覺也同樣會(huì)受到影響?；蛘哒f，噪聲能夠輕易地將人們的注意力從食物的味道上轉(zhuǎn)移。

But it's not all bad news for loud restaurants. In a second study, students rated crunchy foods as crunchier in the presence of loud white noise—perhaps because it tuned them into the sound of their food. The researchers say this study may explain why airline food ain't earning any Michelin stars. Me, I think there's a little more to it than the engine noise.
不過餐廳環(huán)境嘈雜也不是完全沒有好處。另一項(xiàng)研究表明，聽著嘈雜的白噪聲，學(xué)生們覺得松脆的食物更可口了——也許嘈雜的噪音正好和嚼食物咯嘣咯嘣的聲音步調(diào)一致了……研究人員稱，這項(xiàng)研究可以解釋為什么飛機(jī)餐從未獲得過米其林之星。我想，這不僅僅是因?yàn)榘l(fā)動(dòng)機(jī)的噪音吧……
