Summary This episode has all the bells and well as lots more things that make noise! Dr Rob and the team give a big "shout out" to all things that are loud, and have some noisy fun with sirens, snoring and drumming to explain the science behind loudness. LOUD 101What does it mean to be loud? Dr Rob explains with the help of a handy decibel meter, comparing tiny noises, like the hum of a mosquito, with much louder ones like the fiery explosion of a hydrogen-filled balloon!EXPERIMENT: AMPLIFICATIONYou can make some pretty interesting sounds with household objects, but some of them are barely noticeable at first! Julia experiments with buckets, coat hangers and a table (among other things) to make some tiny sounds loud!DRUMMINGIf you've ever lived next door to a drummer, you'll know that drums easily qualify as things that are loud. Salvador Persico from Blue King Brown gives us the lowdown on different drum types, and with his fellow band members creates some seriously cool (and loud) beats.Brett Duce from the Princess Alexandra Hospital's Sleep Disorder Lab has listened to more than his fair share of snoring. He takes us through how and why it happens, and just how you can go about proving to someone that in their sleep, they can be very loud!BELLSChurch bells have to be loud to be heard over the general noise of a busy city. Physicist and bellringer Ian McCulloch takes us into the St John's Cathedral bell tower and shows us just how these bells can be so loud.SIRENSHave you ever been stuck in traffic and wished you had a siren to help you get through faster? Don Wilkie from the Country Fire Authority shows off the CFA's fleet of fire engines and demonstrates all the loud noises they can make!So join Dr Rob as he booms, blasts, beats and yells his way around the science of Loud. as he once again proves that the ordinary really does become extraordinary; under the SCOPE!
