Modern technology continues to fascinate the world with its quick and efficient improvements to our daily lives. The perforated cylinder, for instance, is an important part of our present and future that you probably did not even know was there.
Automotive
Almost all automobiles on the road today utilize a noise-damping technology known as the muffler, which disperses the exhaust out of the back of the car to quiet the noises emitting from the engine. Inside of the muffler, a set of tubes direct the gases and sound waves through openings to various chambers, in the middle of which is a perforated cylinder set that works to interrupt the flow of exhaust. This effectively diffuses the sound, canceling out the noise created by the combustion engine.
Resource Gathering
Offshore drilling is responsible for a significant amount of the oil that fuels our modern world. The process of removing crude oil from benefit the ocean floor requires a filtration process that is only possible with the use of a perforated cylinder system. Without this system, the crude oil could not be separated from the salt, water, and other impurities from the surrounding environment.
Exploration
The perforated cylinder has even played a role in the exploration of space. Thanks to its applications in heat dispersal and structural integrity, this technology lends itself to the cutting-edge needs of space exploration. The wiring needed to carry complex information can be directed through a ported tube that also provides a strong frame for the spacecraft. The perforations release the massive amounts of potentially heat heating created by the circuitry. This method has been used on multiple space missions, including the robotic rover on the surface of Mars.
Audio Applications
Similar to the concept behind the muffler, diffusing sound can dampen audio waves. The perforated cylinder can provide effective sound proofing in both studio and car settings, allowing for higher quality recordings. The most recent uses, however, are the more impressive. Newer speaker models are taking the shape of tubes that can project sound in multiple directions. This round shape, when constructed from strong materials, makes for sturdier speakers that can support wireless connectivity with modern smart phones and laptops. This design is changing the way our modern world looks, as we move away from monitors and PA systems that rely on unidirectional projection.
Many of the foundational technologies of the modern world are out of sight. Although we may not always be aware of them, advances like the perforated cylinder make many of our modern wonders possible.
