This new sound-based fire extinguisher puts out flames by
Two engineering students from George Mason University have built a rather unorthodox fire extinguisher. It uses a subwoofer to send sound waves powerful enough to extinguish small fires.... But the goal was to create something portable and affordable like a fire extinguisher that would generate the sound wave at the correct frequency, which they were able to do with the help of an
When Fire Strikes Stop Drop and... Sing? Scientific
The mini-extinguisher designed by Robertson and Tran disrupts the natural combustion process by pulsing waves of sound along the bottom layer of the flames. At superbass-y levels, these sound... However, if un-vaporized fuel remains hot enough, it will flare up again when the sound waves cease. (2) A shock wave, or blast wave, may displace hot gas and vaporized fuel from the source of a fire, and spread it over a wide area, cooling it and extinguishing the flame.
A waterless & chemical-free sound wave fire extinguisher
Basically, by directing a stream of low-frequency sounds at the flames, the device is able to create pressure waves in the air and rob the fire of oxygen — effectively choking it out. how to put pdf file into one It works but doesn't seem quite good because the fire hardly react to the sound wave because the diaphragm are very small. I have improve it by change the small speaker to the normal speaker (with subwoofer), and enlarge the diaphragm by using funnel water and attached it to the tube. It works....but doesn't seem very nice.

With many possible applications, fighting fire with sound is a promising venue, in which sound pressure waves can be used to save an important control center, or an astronauts life. My project is about using sound pressure waves to extinguish fire. how to return uid firestore Fighting forest fires can be a huge challenge, as they’re often in remote areas, hard to reach.

How To Make Sound Wave Fire Extinguisher
Two engineering students from George Mason University have built a rather unorthodox fire extinguisher. It uses a subwoofer to send sound waves powerful enough to extinguish small fires.
- The goal was to create something portable and affordable like a fire extinguisher that would generate the sound wave at the correct frequency, which they were able to do with the help of an oscilloscope that measured the waves. They connected their frequency generator to a small amplifier and linked the amplifier to a small electric power source. These are hooked up to a collimator that they
- Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation.
- The principle behind the extinguisher is simple: as they are mechanical pressure waves that cause vibrations in the medium in which they travel, sound waves have the potential to manipulate both burning material and the oxygen that surrounds it. If the sound could be used to separate the two, the fire would be starved of oxygen and, accordingly, would be snuffed out.
- The sonic fire extinguisher by two final-year undergraduate engineering students, Seth Robertson and Viet Tran, uses sound waves spread through a mobile subwoofer gun to put out flames, rather than the chemical compounds used by traditional fire extinguishers.
