Series N, Episode 3 - Nosey Noisy
- The buzzers are the panellists favourite sounds. Aisling's buzzer is of a baby giggling, although not her own as she is not a mother. Ross's buzzer is of his two daughters quoting Indiana Jones, with his youngest daughter Willow mispronouncing the letter "s" as "r" so "I hate snakes" becomes "I hate rakes", and eldest daughter Elfie saying: "I am Mola Ram!" Corey's buzzer is of a Slipknot track. Alan's buzzer is the klaxon. (Forfeit: Klaxon)
- The loudest thing anyone has ever shouted is the word: "Quiet!" Anneliese Flanagan, a primary school teacher from Belfast, is in the Guinness Book of Records for having the loudest voice. In 1994 she entered a shouting competition and her record has never been broken. She logged 121 decibels, which is exactly the same as a chainsaw, or 32 times louder than a vacuum cleaner, and she can shout twice as loud as the human pain threshold.
- The panel are given a musical instrument and are asked how to play them. The answer is that you play them with your nose, because they are nose flutes. The first patent for them was in 1892 for a version called the Nasalette, and the idea was that it left your hands free to play other instruments if you strapped elastic around them. However, they are much older, having been played in Southeast Asia, the Pacific Islands and the Congo. In Fiji couples would seduce each other with them. It was also tradition to put tobacco on the nose flue so you got a hint of nicotine when playing them. A photo in a 1909 copy of Tatler shows a man from India playing the nose flute and the bagpipes simultaneously. One musicologist described this as, "a peak of woodwind virtuosity."
- If you put a frog on helium, it makes no change to the noise. In 1993 scientists made three different species of frog inhale helium and it had no effect because frogs don't use the resonance of the air inside their vocal tract like humans do when speaking, they create resonance using their skin. (Forfeit: Ribbit [said in a higher timbre])
- If a dinosaur sucked on a party balloon full of helium, their voices would change the same way as a human's does. In 2015 Austrian scientists gave helium to a Chinese alligator, the closest living relative to the dinosaurs, and proved that the timbre changes, making their voices sound lower. Helium does not make your voice higher, it just changes some of the higher frequencies in the voice to be amplified so you can hear them more. As the Chinese alligator is related to the dinosaurs, the same must be true of them.
- The panel are given some horns and are asked what they are used for. They are used to hear foetal heartbeats. It is a Pinard horn, invented in 1895 by French obstetrician Adolf Pinard, and the design has never been improved upon.
- The panel are played a recording of hot water being poured into a bowl and a recording of cold water being poured into a bowl, and are asked which recording is which. The first is the hot water, and on average 96% of people can tell the difference between hot and cold water from the sound. Hot water is slightly less sticky, and when it hits the surface it breaks up into smaller particles and makes a higher pitched splash.
- XL: You would want a falcon nose on a plane to prevent the engines from being damaged. Falcon beaks are shaped to make them more aerodynamic. Aeroplane engines used to have a problem when they reached a certain speed, because the air in front created a wall of resistance that caused the engine to choke. While falcons can fly at 200mph, each nostril has a cone-shaped passage in it which directs the air into their nasal passages. Thus engineers created a similar cone on the front of jet engines that allow the air to enter the engines, even at supersonic speeds.
- XL: Sandi gives the panel a mystery artefact to identify, lent by the Horniman Museum. It is a sperm whale's eardrum.
- Out of a VW Beetle, a male gorilla, a four-poster bed and an elephant, a blue whales heart is closest in weight to the gorilla. While many people though it was the same weight as a Beetle, no-one had ever actually checked until recently. It weighs at 28.5 stone, which is 22% the weight of the Beetle. (Forfeit: The Beetle)
- If Sandi was in a car and she tooted her horn and flashed her lights at the same time, the one you would see first depends on how far away she was. The brain processes sound faster than light, so if you are close enough you will hear the horn first, but if the car was far away the light will be processed first because light travels faster. Human hearing can detect frequencies between 20 to over 20,000 hertz, but human sight only detects a much smaller frequency.
- The vitamin that can stop you from getting a runny nose is Vitamin D. There is hardly any evidence to show that Vitamin C relieves the symptoms of a cold. Vitamin D however helps prevent colds in the first place. One Vitamin C tablet contains 10 times the recommended daily allowance of the vitamin. (Forfeit: C)
- If you put a duck in an echo chamber the chances are that nothing will happen as most ducks don't quack at all. The ducks that do quack are female mallards, and their quacks do echo. Other ducks whistle, coo, yodel and some are silent. (Forfeit: Ducks' quacks don't echo)
