Are the latest ear plugs better for gigs, focus and sleep?

In this special edition of Sliced Bread, recorded at the Hay Festival in South Wales, Greg Foot investigates the newer style of ear plugs. He's joined by listener Marni who's seen adverts for brands like Loop, which promise to protect your hearing at higher volumes while still allowing you to enjoy music at gigs. Other models in their range claim to give you better focus, shutting out extraneous noise but still allowing you to hear conversation. Or, in the case of their 'Quiet' model, sleep better.

As ever Greg's joined by two experts to deep-dive into the science and find out if the evidence backs up the marketing claims. And with the help of a special dummy head fitted with microphones, they carry out a series of tests to hear the difference between traditional foam ear plugs and the newer models.
