00:00:03.759 --> 00:00:09.559
and that is exactly what we're talking

00:00:06.960 --> 00:00:13.960
about sound dampening but does sound dampening really have a role in our

00:00:11.719 --> 00:00:19.840
daily lives well if you spend any time in a house apartment or car it

00:00:17.119 --> 00:00:24.599
definitely does so sound travels in waves of pressure that can both go

00:00:22.279 --> 00:00:29.199
around and reflect off of objects and there are three main ways that we deal

00:00:26.519 --> 00:00:33.800
with unwanted sound the first is distance sound waves don't travel

00:00:31.759 --> 00:00:37.200
forever as you can observe if you're trying to hear your friend across a

00:00:35.480 --> 00:00:40.079
baseball field and you can't quite tell whether he wants you to throw the ball

00:00:38.480 --> 00:00:46.039
for a double play or a permission to date your sister the second is using

00:00:43.160 --> 00:00:50.600
active anti-noise generators also known as noise cancellation which you can

00:00:47.680 --> 00:00:56.160
learn more about here the third is by reflecting and or absorbing unwanted

00:00:54.039 --> 00:01:01.039
sound using different shapes and materials so for this example let's say

00:00:58.680 --> 00:01:05.479
that sound is like a rubber ball if you throw it at a concrete floor it'll

00:01:03.239 --> 00:01:10.320
bounce and reflect off in another Direction but if you throw it at

00:01:07.200 --> 00:01:12.240
something like a bed of pillows most of

00:01:10.320 --> 00:01:17.479
the energy from the ball will be absorbed a more comprehensive solution

00:01:15.240 --> 00:01:21.759
is a combination of the two with soft shapes designed to both reflect and

00:01:19.920 --> 00:01:27.360
absorb sound and this is usually found in spaces like recording studios where

00:01:24.200 --> 00:01:30.119
sound isolation is extremely important

00:01:27.360 --> 00:01:34.000
there are even spaces so well isolated or sound proofed for special

00:01:31.960 --> 00:01:37.520
applications that people have trouble spending a long period of time in them

00:01:35.680 --> 00:01:43.280
claiming that the sound of their own heartbeat became frustratingly loud

00:01:40.960 --> 00:01:47.000
yikes but since most of us probably don't live in recording studios or

00:01:45.000 --> 00:01:50.880
soundproof Chambers for scientific research how exactly does sound

00:01:48.920 --> 00:01:56.360
dampening really affect us in day-to-day life well sound proofing is actually

00:01:53.320 --> 00:01:59.159
used in lots of things cars use sound

00:01:56.360 --> 00:02:02.799
dampening in mufflers and resonators so we don't all sound like race cars in

00:02:01.200 --> 00:02:07.680
traffic except for that one guy who lives on my block and they also use

00:02:05.439 --> 00:02:12.080
insulating layers to reduce the sound made by traveling down the interstate

00:02:09.879 --> 00:02:16.760
Nissan actually built an electric car that was so quiet that the sounds of air

00:02:14.680 --> 00:02:21.000
moving over the car were discomforting to passengers and to solve this they

00:02:19.239 --> 00:02:26.599
actually had to make specially shaped headlights to deflect air around the car

00:02:24.160 --> 00:02:31.800
reducing noise and making that a method of sound dampening houses of course have

00:02:29.400 --> 00:02:36.920
insul in the walls to help with climate control but also to assist with keeping

00:02:34.319 --> 00:02:41.800
unwanted sounds out many modern houses use Windows made of multiple separated

00:02:39.560 --> 00:02:45.680
layers with airspace in between to help them absorb sound and to prevent heat

00:02:43.879 --> 00:02:49.959
transfer and if that's not enough there are actually special kinds of drywall

00:02:47.800 --> 00:02:54.280
and even glue that you can buy so your living room won't sound like an echoey

00:02:51.959 --> 00:02:58.400
Cavern when someone upstairs scoots a chair around many businesses actually

00:02:56.280 --> 00:03:02.760
use special panels in the ceilings to help absorb unwanted sound which is

00:03:00.519 --> 00:03:08.360
important for privacy reasons as well as just general workplace comfort and

00:03:06.080 --> 00:03:13.200
speaking of the office we can also use computer cases with sound dampening foam

00:03:11.400 --> 00:03:19.319
built right into them to block out the noise from cooling fans so then what's

00:03:16.840 --> 00:03:24.000
next remember those three main ways to dampen sound well soon there may

00:03:21.440 --> 00:03:28.159
actually be a fourth scientists are using quantum mechanics to produce new

00:03:26.120 --> 00:03:33.040
materials for sound dampening that would allow for the redirection of sound

00:03:30.599 --> 00:03:37.200
across a material surface without allowing any vibrations to travel

00:03:35.239 --> 00:03:41.760
through it that means in the future it may take much less material to isolate a

00:03:39.720 --> 00:03:47.239
space and it could potentially be used to reduce noise pollution in things like

00:03:44.000 --> 00:03:51.319
busy cities airfields and even the

00:03:47.239 --> 00:03:53.519
trains that are right next to our studio

00:03:51.319 --> 00:03:59.480
speaking of not needing as much mass to absorb sound Mass drop has another one

00:03:56.920 --> 00:04:03.239
of their pretty killer deals going on today today the featured deal today is

00:04:01.560 --> 00:04:10.159
an LG 3494 very similar to this 34in ultrawide

00:04:07.439 --> 00:04:14.400
flat panel that I reviewed way back about a year ago the cool thing though

00:04:12.439 --> 00:04:19.160
is that unlike that one this one can be had for as little as

00:04:16.160 --> 00:04:21.799
649 through Mass drop if it reaches the

00:04:19.160 --> 00:04:26.080
lowest price of course this product is available only through Mass drop at the

00:04:23.759 --> 00:04:29.919
significantly discounted price thanks to their group by model which the way it

00:04:28.320 --> 00:04:33.280
works is essentially the community is like hey there's a bunch of us who want

00:04:31.440 --> 00:04:37.600
to buy this thing and mup goes hey that's cool they go to authorized

00:04:35.240 --> 00:04:41.800
distributors or to the manufacturer themselves and they negotiate a price

00:04:39.759 --> 00:04:47.400
and then the more people actually commit and put money down the lower the price

00:04:44.560 --> 00:04:53.080
drops and they've got tons of other items everything from knives to uh

00:04:50.520 --> 00:04:58.479
computer hardware to keyboards to audio equipment filming equipment lots of

00:04:55.360 --> 00:05:01.000
great stuff so head over to draw do/

00:04:58.479 --> 00:05:04.720
tequ Linked In the video description to check it out now the link doesn't give

00:05:02.800 --> 00:05:09.759
us a kickback or anything but it does let Mass drop know that we sent you over

00:05:07.199 --> 00:05:12.800
