every time we shoot a video in our new workshop we run up against the same
problem every time i talk you can hear an echo
echo echo okay it's not quite an echo what it actually is is reverb and it's
caused by a standing sound wave that is bouncing back and forth inside the room
now it is something that you can address in post but as you guys can hear right
now sometimes the solution is worse than the
problem unless of course you go right to the
source we uh with the help of elgato
ah are going to be deploying a literal
mountain of their wave panels these are
mostly designed for streamers but the thing is if you've got a good high
quality acoustic panel ready nicholas
you can use it for pretty much anything so we're gonna go one stage at a time
with each of these boxes costing about 100 us dollars and c do they do anything
and if they do anything how much do you need before you get some
kind of measurable impact and how far can you go before i tell you
about our sponsor thanks jackery for sponsoring this video from september
20th to october 11th jackery is celebrating their ninth anniversary with
a photo contest to win some of their products click the link in the video
description to learn more
in every wave panel starter set you get everything you need to acoustically
treat about one square meter or ten square feet of wall or ceiling you get
six of the wave panels themselves a bunch of brackets as well as joiners
in case you want to bind them together and make cool
geometric patterns on your wall as well as instructions and everything you will
need to mount them before we can mount anything though we need to get a
baseline reading of the current state of the room now there are two main ways we
record audio for our videos either with a lavalier microphone under my shirt or
with a shotgun microphone that's mounted out of the frame and you guys can hear
the difference in how those sound the quick brown fox jumped over the lazy dog
the quick brown fox jumped over the lazy dog
then in order to science it up a little bit we're gonna
switch over to this puppy right here this is the umic one an omnidirectional
condenser microphone from mini dsp that is specifically designed for taking room
measurements like this the software we're going to use is called rew or roo
we just click measure rename it to control no panels
and start you guys are going to want to plug yours
wow it's no wonder the audio's so bad in here even with all the stuff that we
have in the room now i mean it was worse before we are still seeing standing
waves that are lasting as long as about 0.9 of a second
hard to listen to now the goal isn't to turn this place into an anechoic chamber elgato wave
panels would not be the way to do that we just want to cut down on reverb so
the first thing we need to know is how much actual wall and ceiling area there
is in this room so we've got 10 23 times two that's the
ceiling in the floor and then you want to give me those wall measurements we
got 13 carry the one i don't think i have ever carried the
one on camera ah yes there 35 13. i remember to carry the one
forgot all the other basics why don't we target five percent coverage and see
what happens stage two ten percent stage three i mean that
better that better do it yeah
profit seven we have one small problem my control i
said it was with no panels in the room i had these ones sitting here so nobody
touched these we have to i want to keep this scientific boys so these are off these
are off limits this pack though this wasn't in here james
these are a little bit finicky but given that it's something you're only going to
do once not bad actually elgato not bad full
disclosure the reason we have that omnidirectional speaker and the reason
we already know how to use this software is because it is our intention to make
our own acoustic panel product
but that doesn't mean that i'm going to say this is anything but
damn looking pretty good of course the performance is ultimately
what matters more so these aren't the thickest acoustic
panels in the world that cause me some concern the thinner they are the lower
the band of frequencies they will absorb thinner meaning higher frequencies only
but it is two different materials that's
cool because you know you've got a low density foam here and a high air density
foam here plus any time that sound goes through a medium change that's pretty
good for absorption then the setup you don't have to read
the instructions at all at least i hope so because i didn't uh they're really
easy to clip together and then they just friction down into the holes that are
already on the foam not the most secure
i might i might put some adhesive in there if it
was missing critical but if i was going to ceiling mounted i
would on the wall it's probably fine now what are you thinking in terms of
placement do we want to put individual panels just kind of around do we want to
clip them together in kind of geometric shapes and go for large flat surfaces
are we targeting the walls the corners i think that you want to have big
contiguous patches where possible like look between those two blue pipes over
there or right there but then because there are so many different gadgets and
machines in here there's some spots where you don't have much room just do
what you can in those spots a mix okay the clips go in the front just two
kind of flimsy honestly but as soon as you
add a third you've tripled the joins so it's quite a bit more rigid
it's still i mean it's not structural but we're climbing
it can you hold this for me please i'm just going to climb this climate
climate sebastian i mean if the laser level can't support
my weight it's not a good laser level don't go in the lid
uh yeah climate stick tips yeah there's absolutely no reason to put
the foam these foamies on before you hang it on the wall so now we know
that's a tech tip does it look level yeah it looks good
there you are all right
just lean just thrust
i love you wall you're awesome now that we've seen how
much space even one pack takes up on the wall we're rethinking our strategy for
laying them out a little bit so what we're going to try to do is in each area
we want to put panels we're gonna put half as many as would fit now so that
one we're gonna expand by adding another six and then this one here we're gonna
lean a little low so we can go one two
three four more kind of thing when it's time for the second round of testing
i'm good everything's good quick thought james before we assemble a
full frame for the ceiling why don't we just try sticking one to
the ceiling and see if this tape actually holds i think the frame will
hold but what about the foam isn't it just gonna fall off
only one way to find out uh do you mind passing me just one of those single frames uh there's some right there
oh thanks david
yeah there you go okay
there you go there you go bud stretch
the tape is on that side yeah i see it
there's no way this works i am not super hopeful i don't think you
got that one corner closest to you
i guess you're ready to double down now yeah let's do it okay let's get the
ladder does elgato intend for these to go on the ceiling uh i think this is
outside their scope
sorry a little bit ceiling crap
you okay
feels like i inhaled a feather or something do you have a water bottle
here unfortunately no my
lttstore.com water bottle is not here otherwise i'd be fine
the idea is to distribute our five percent as though that's all we have so
we're going to try and get some paneling on pretty much every
surface uh bell over there is mounting free above the eye wash station for
example now obviously before we roll out a bunch
of these next to something like a welding station we want to make sure they have at least
some level of fire resistance see if i can actually
there you go okay we have a fire extinguisher don't worry
it's right there
that's a lot of heat okay wow i'm convinced
should be fine this was one we cut up for a different deployment over on the
podcast set so it's a sacrificial one oh
it stinks but yeah what could go wrong
he sings this while he's holding things over expensive equipment yeah what could
go wrong they definitely work better on the wall
than they do on the ceiling although so far everything we put up has stayed
but you know what's more impressive is everything we've got up here so far is
still cheaper than yeah this thing this kit from auralex
660 dollars for like honestly
i'd be surprised if that single foam type one even performs as well as this
we'll see they're thicker though i think uh not really
fair enough you know what guys we've got 19 more panels to put up and i don't
know about you guys but i'm already noticing a
huge difference we're back on both my 416 as well as my
lavalier microphone you guys can hear the differences between those the quick
brown fox jumped over the lazy dog the quick brown fox jumped over the lazy dog
now i'm just gonna come around here and
we're gonna do a second sweep okay approximately five percent coverage and
start we retested last time i moved away so
dang that's actually i mean
it's not that i can't hear the difference i can totally hear the difference i like i believe it but still
that's really impressive five percent coverage with these things and we went
from a peak of 0.9 seconds at sort of around the
range of my speaking voice all the way to about point six point six and change
i mean you can tell el elgato clearly targeted
human speech frequencies because that's what this product is designed for
because that's where we see the biggest improvement right in that 400 to
approximately 1500 hertz range
wow even up to around three kilohertz it's like pretty darn good like how does
it sound better to you if i'm hosting a video okay david we're we're building
this computer this is a super cool build by the way make sure you're subscribed
so you don't miss this one sounds way better
wow that's awesome let's put up a few more let's get that
big flat spot there dealt with i don't know maybe like you know a strip down
there and then we'll we'll call it yeah
everything's been going really well so far but david i just noticed something i thought i was kind of imagining it
before but look at this there's some inconsistency in the color of the
foam so if this was a major aesthetic
thing for you um just be aware like this one's basically
silver compared to this one which is more like black do you see that yeah i
didn't i wasn't sure until i saw these two next to each other like they're a
little all over the place but if you buy one pack i would imagine they're closer
at least without any clear objective we kind of put some more on until it looked
nice i think it looks pretty nice in here and we ended up with a total of 210
square feet which it's kind of looking dangerously close
to 69 percent hold on let's check it 10 divided by 35 30.
5.9 5.9 one short but that's okay
let's go ahead and run our second our third rather our third
sweep actually wait i forgot to do this again the quick brown fox jumped over
the lazy dog the quick brown fox jumped over the lazy dog all right okay now
let's do our sweep i i think it's actually better again i could be wrong i
could be imagining it that is why we have objective
measurements we added another six boxes giving us approximately
5.9 coverage and let's go ahead and start it guys ready
wow big improvement again check this out
guys we just shaved off another anywhere from
0.1 to 0.2 of a second in the range that
we care about which is kind of in here this is honestly way better than i
expected like this is completely usable now i we could keep putting on panels
but honestly i just don't really feel like it's necessary we can take these panels we can treat other areas in the
studio i you know what you guys might
look at the cost of this 2100 and you might think whoa that's a lot of money
and it is but compared to what normal acoustic treatment panels cost from
specialty vendors they are darn freaking reasonable remember this is a big room
now obviously you could save a lot of money doing it yourself with rock wool
or ultra touch batting and a wooden frame
absolutely but considering the overall package here i think Corsair's got
excuse me elgato has a winner on their hands
just like our sponsor's a winner thanks to skylum for sponsoring today's video
coming this winter skylim is releasing their newest creative photo editing
software luminor neo it's made by the team behind luminer ai and luminer neo
was created on a brand new engine for increased performance and comes with
some brand new features their new relighting options have luminor neo
analyzing your image to recognize depth and allowing for precise control over
exposure and tone you can remove blemishes and artifacts left by a dirty
camera sensor or remove those power lines interrupting your photo with ease
there are also new powerful background replacement features to quickly swap out
your background for different scenes the new engine also allows for complex
layering of several raw images without significant performance loss so don't
wait reserve your copy of lumen or neo today to ensure that you get a copy at
their limited early bird pricing using the link in the video description if you
guys are looking for another video to watch by the way elgato provided panels
for this one but they actually sponsored a full elgato streaming setup video
where we're gonna have literally all elgato and have a look at what the
complete package looks like so we'll have that linked down below
yeah yeah yeah yeah let me get let me get right on that i'm gonna get down
real careful oh god oh god oh god no no i'm kidding
i'm fine
