In this episode, Demitris Deech "brings the noise" as he tells us all about the sirens used by emergency vehicles and all the names those various sounds have, and when they're used.

Faye Hatcher is getting a bit wound up about Sports Trailers on the radio and how cliched and repetitive they can be. Dave Harries, meanwhile, is thinking about summer holidays, and our love affair with budget airlines to get us to the sun, sea and sand quickly and cheaply.
