revealed that Walkers Crisps had designed noise-free crisps, to be marketed as "Ready Silent Cri-sshhp." They would allow people to "eat loud snacks in the cinema without disturbing the person next to you." The crisp was said to have "the same flavour and crunchiness, except it comes already crushed."
The snack food firm has been working with acoustics experts at the London Institute of Sound Performance (LISP) to produce the 'silent' crisp. LISP says that research showed 90pc of the loud crunching noise associated with a packet of crisps comes from the first bite. If successful they will be rolled out in the UK, Europe and in the Middle East through Walker's partner Deloof Neeb Evuoy.
