From CNN Living: People increase their rate of chewing by almost a third when listening to faster, louder music, accelerating from 3.83 bites to 4.4 bites per minute.
It turns out these not-so-good vibrations might be on purpose. Studies show people drink more, eat faster and leave sooner when the bass is thumping, so restaurants are bringing the noise.
Customers have been sounding off in recent years about the deafening volume level in restaurants.
Washington Post food critic, Tom Sietsema, has gone so far as to include the average decibel count into his restaurant reviews and former New York Times restaurant critic Frank Bruni famously docked chef Mario Batali’s flagship restaurant Babbo one star for its ear-splitting rock soundtrack.
There is, he wrote, “Lou Reed and Moby, at a volume that rises around 10:30 p.m., as if patrons are being cued to chew faster.”
The study shows that in loud environments men consume more drinks in less time. This is an interesting article, which also covers the effect of room colors on diners, and how restaurants keep track of slow diners so that they can deny them reservations in the future. You can read it here.
