Sound Dampening As Fast As Possible

2015-12-11
and that is exactly what we're talking about sound dampening but this sound dampening really have a role in our daily lives well if you spend any time in a house apartment or car it definitely does so sound travels in waves of pressure that can both go around and reflect off of objects and there are three main ways that we deal with unwanted sound the first is distance sound waves don't travel forever as you can observe if you're trying to hear your friend across a baseball field you can't quite tell whether he wants you to throw the ball for a double play or a permission to date your sister the second is using active and tiny noise generators also known as noise cancellation which you can learn more about here the third is by reflecting and/or absorbing unwanted sound using different shapes and materials so for this example let's say that sound is like a rubber ball if you throw it at a concrete floor it'll bounce and reflect off in another direction but if you throw it at something like a bed of pillows most of the energy from the ball will be absorbed a more comprehensive solution is a combination of the two with soft shapes designed to both reflect and absorb sound and this is usually found in spaces like recording studios where sound isolation is extremely important there are even spaces so well isolated or soundproofed for special applications that people have trouble spending a long period of time in them claiming that the sound of their own heartbeat became frustratingly loud yikes but since most of us probably don't live in recording studios or soundproof chambers for scientific research how exactly does sound dampening really affect us in day to day life well soundproofing is actually used in lots of things cars use sound dampening in mufflers and resonators so we don't all sound like race cars in traffic except for that one guy who lives on my block and they also use insulating layers to reduce the sound made by traveling down the interstate me Sam actually built an electric car that was so quiet that the mounds of air moving over the car we're discomforting to passengers and to solve this they actually had to make specially shaped headlights to deflect air around the car reducing noise and making that a method of sound dampening houses of course have insulation in the walls to help with climate control but also to assist with keeping unwanted sounds out many modern houses use windows made of multiple separated layers with air space in between to help them absorb sound and to prevent heat transfer and if that's not enough there are actually special kinds of drywall and even glue that you can buy so your living room won't sound like an echo II cavern when someone upstairs scoops a chair around many businesses actually use special panels in the ceilings to help absorb unwanted sound which is important for privacy reasons as well as just general workplace comfort and speaking of the office we can also use computer cases with sound dampening foam built right into them to block out the noise from cooling fans so then what's next remember those three main ways to dampen sound will soon there may actually be a fourth scientists are using quantum mechanics to produce new materials for sound dampening that would allow for the redirection of sound across a material surface without allowing any vibrations to travel through it that means in the future it may take much less material to isolate a space and it could potentially be used to reduce noise pollution in things like busy cities airfields and even the trains that are right next to our studio speaking of not needing as much mass to absorb sound mass drop has another one of their pretty killer deals going on today the feature deal today is an LG 34 um ninety four very similar to this 34 inch ultra wide flat panel that I reviewed way back about a year ago the cool thing though is that unlike that one this one can be had for as little as 649 through mass drop if it reaches the lowest price of course this product is available only through mass drop at this significantly discounted price thanks to their group by model which the way it works is essentially the community is like hey there's a bunch of us who want to buy this thing in mousetrap goes hey that's cool they go to authorized distributors or to the manufacturer themselves and they negotiate a price and then the more people actually commit and put money down the lower the price drops and they've got tons of other items everything from knives to computer hardware to keyboards to audio equipment filming equipment lots of great stuff so head over to draw dumps slash tech quickie linked in the video description to check it out now the link doesn't give us kickback or anything but it does let mass drop know that we sent you over there to shop so thanks for watching guys if you liked this video click that like button if you didn't then hit this like leave a
