Stonehenge searching for whispering gallery wave using FDTD Trevor Cox 2020-04-24 | Explores whether sound skims around the inside of the outer sarsen circle like in a whispering gallery using a FDTD (Finite Difference Time Domain) model. The whispering-gallery waves are the ones that creep along the inside of a curved surface, taking longest to get to the other side of the circle, but with little attenuation.But because of the amorphous stone shapes and gaps at Stonehenge, by the time the whispering gallery wave has creeped to the other side of the circle, it would be inaudible.2D Simulations by Richard Hughes @SalfordAcoustic. The source has a cardiod response. #acoustics #silentmovie #stonehenge
Whispering gallery wave simulation for cylinder and broken culinder using FDTD Trevor Cox 2020-04-24 | Shows how sounds skim around the inside of a cylindrical whispering gallery using a FDTD (Finite Difference Time Domain) model. The whispering-gallery waves are the ones that creep along the wall, taking longest to get to the other side of the circle, but with little attenuation. Hence whispers along the wall of a whispering gallery arrive at the other side surprisingly loud.The concave surface of a sphere does not allow the beam cross section to expand as fast as during propagation in free space. In 3D sound crossing straight across the space loses 6 dB per distance doubling (inverse square law), whereas the whispering-wave loses 3 dB per distance doubling. Simulations by Richard Hughes @SalfordAcoustic. The source has a dipole response. #acoustics #silentmovie
Listening devices: Funnelling sound Trevor Cox 2019-03-28 | How to make them: http://salfordacoustics.co.uk/listening-devicesThe listening devices play with ambient sound and create a starting point for talking about sound and hearing. They're especially useful for science shows and fairs where it's really noisy and so other acoustic demos are difficult to do. The video allows you to get a sense of what it sounds like to wear the devices by using a dummy head recording.

Demonstration of continuity illusion Trevor Cox 2018-12-28 | Demonstration of continuity illusion. You will hearing an intermittent beeping sound. There is a short burst of noise in the gaps between the beeps. When the hiss is loud, as happens in the middle of the video, the beeps sound no longer intermittent. This is an illusion in the brain, the beeps are exactly the same throughout the video. Your brain is imagining a constant tone even though it does not exist in reality.
Vibrating angel plate Trevor Cox 2018-12-26 | This Christmas angel has got some moves, but its disturbing when it hip thrusts. The video of the vibrating angel-shaped plate goes from low to high frequency and was made using a computer simulation.

Playing the Echo, 360 video, Salford University Trevor Cox 2016-10-29 | This 360 video with surround sound (Headphones needed) illustrates some of the strange echoes created by the domed ceiling of the circular reading room in Manchester Central Library. The strength of the focus from the ceiling causes the sound from some instruments to appear to come from the wrong place. Note: The marimba is hidden from view.'Pillars of Wisdom' by Prof Alan Williams (@AlanWilliams123) using Ambisonic recording. The piece plays with the slap-back echo in the Reading Room at The Manchester Central Library. Performed by Gravity Percussion. Recorded for Manchester Science Festival 2016 as part of the Playing the Echo event. Sound and video by @trevor_cox and Danny Wong-Mcsweeney of Acoustic Research Centre, University of Salford. Audience members could wander the room to find different listening experiences depending on whether they were near a dome focus or not.More about the recording at acousticengineering.wordpress.com/2016/10/29/playing-the-echo

Giant cornstarch monsters using industrial shaker instead of loudspeaker Trevor Cox 2015-07-17 | You might have seen the Big Bang Theory guys doing the cornstarch and loudspeaker experiment. The Acoustics Research Centre at the University of Salford thought we'd go one better by making a giant version using 10 kg of maize starch, a paddling pool and an industrial shaker. What was the biggest cornstarch monsters we could make?
I am sitting in a room with worlds longest echo Trevor Cox 2014-04-11 | A rendition of Alvin Lucier's I am Sitting in a Room played using the Inchindown Oil Tanks that hold the Guinness World Record for having the 'longest echo'. The text passes through the oil tanks multiple times, until all that remains are strange tones created by this long feedback loop. The immense reverberance of the oil tanks give a very different feel to the early evolving sound compared to renditions using more conventional concert halls. The impulse response of the oil tank was measured as part of research for The Sound Book / Sonic Wonderland.

How Science Works KS3: Journey to Etna Trevor Cox 2011-04-27 | Clive Oppenheimer, a volcanologist working on the latest techniques to monitor and predict volcanic eruptions, demonstrates his work at Mount Etna, an active volcano in Sicily.Download videos and extensive curriculum and CPD resources at doi.org/10.17866/rd.salford.11637798Volcanic eruptions pose a real threat to communities living nearby, and at their most violent they have wiped out whole cities. Clive is an expert in developing new techniques for monitoring volcanoes, and works with scientists around the world. It's a difficult job, because most of the activity happens deep below ground.Clive meets with his research students who monitor the volcanoes. To look at how the latest techniques are developing, he takes a trip up Etna to collect fresh lava samples, then heads to the Institute of Volcanology (INGV), about 20 km away, to analyse some of the new data.
Using Asthma on the Run: How Science Works KS3 Trevor Cox 2011-04-27 | Science teacher Stuart Murphy takes his Year 8 class through the first lesson in a new scheme of learning in the How Science Works series.Download videos and extensive curriculum and CPD resources at doi.org/10.17866/rd.salford.11637798How Science Works is a key component of the KS3 science curriculum. At Sacred Heart High School in Hammersmith, the Year 8s have just started the Live and Kicking Unit of the curriculum, and here they undertake the first lesson of the unit, called Breathless.The How Science Works video "Asthma on the Run" is used to engage the students at the start and sets up the central theme as well as explain and elaborate on ideas throughout the lesson. Students carry out peak flow tests and measure total lung volume to investigate lung function.The lessons have been developed around an e model of learning with scientific inquiry as its basis. The lessons are divided up into stages which cover all the important learning functions.

Sound Science Lesson Starters Key Stage 3 & 4 Trevor Cox 2011-04-27 | Linked classroom resources: http://salfordacoustics.co.uk/lesson-startersDesigned for year 7 to 11 physics students to show the different effects of sound, as demonstrated in this classroom resource for secondary science, designed to be used on an interactive whiteboard as a lesson starter.Using high-speed camera technology, Trevor Cox, Professor of Acoustical Engineering at the University of Salford, conducts experiments in sound. He firstly shows what happens when rubbing the rim of a glass of water is slowed down to 80 times less than normal speed.Trevor then demonstrates the sound effects of a tuning fork, a triangle, a cymbal and a guitar, as well as the impact of sound on a soap bubble, burning candles and a wine glass.Using an oscilloscope Trevor then shows the difference in frequencies produced by different octaves played on a saxophone.The 'confusaphone' shows what happens when one's left and right hearing is mixed up, and Trevor examines the effect of a sonic boom, created by a cracking whip.He finally assesses the effect of echo and the varying sounds we can create with our own bodies.Originally developed for Teachers TV
KS3 Cross Curricular - Science Gets Fruity Trevor Cox 2011-04-26 | The science of sound is brought to life by a series of cross curricular workshops at St Saviour's and St Olave's School. Pupils are inspired by visits from a physicist, a botanist, and a musician, who help them combine science and engineering with music and physical theatre.The cross curricular day for Year Seven begins with an exploration of the physics of sound through drama. Next up the students get the chance to make music with a range of unfamiliar percussion instruments.Finally they focus on the science of plants in which they are set the challenge of making their own musical instruments out of fruit and vegetables.Downloadable curriculum resources and instructions on how to make instruments at http://www.growingsounds.sound101.org/index.htmlOriginally made for Teachers TV
