1
00:00:00,320 --> 00:00:05,600
every time we shoot a video in our new workshop we run up against the same

2
00:00:04,480 --> 00:00:11,280
problem every time i talk you can hear an echo

3
00:00:08,880 --> 00:00:16,400
echo echo okay it's not quite an echo what it actually is is reverb and it's

4
00:00:13,440 --> 00:00:21,199
caused by a standing sound wave that is bouncing back and forth inside the room

5
00:00:19,199 --> 00:00:24,720
now it is something that you can address in post but as you guys can hear right

6
00:00:23,920 --> 00:00:28,800
now sometimes the solution is worse than the

7
00:00:27,519 --> 00:00:32,719
problem unless of course you go right to the

8
00:00:31,760 --> 00:00:37,120
source we uh with the help of elgato

9
00:00:36,320 --> 00:00:43,360
ah are going to be deploying a literal

10
00:00:39,920 --> 00:00:46,239
mountain of their wave panels these are

11
00:00:43,360 --> 00:00:52,160
mostly designed for streamers but the thing is if you've got a good high

12
00:00:48,719 --> 00:00:54,399
quality acoustic panel ready nicholas

13
00:00:52,160 --> 00:00:58,960
you can use it for pretty much anything so we're gonna go one stage at a time

14
00:00:56,640 --> 00:01:03,920
with each of these boxes costing about 100 us dollars and c do they do anything

15
00:01:03,039 --> 00:01:10,240
and if they do anything how much do you need before you get some

16
00:01:07,760 --> 00:01:14,320
kind of measurable impact and how far can you go before i tell you

17
00:01:12,080 --> 00:01:18,640
about our sponsor thanks jackery for sponsoring this video from september

18
00:01:16,400 --> 00:01:22,320
20th to october 11th jackery is celebrating their ninth anniversary with

19
00:01:20,400 --> 00:01:27,840
a photo contest to win some of their products click the link in the video

20
00:01:23,920 --> 00:01:27,840
description to learn more

21
00:01:34,960 --> 00:01:41,040
in every wave panel starter set you get everything you need to acoustically

22
00:01:38,400 --> 00:01:47,200
treat about one square meter or ten square feet of wall or ceiling you get

23
00:01:44,320 --> 00:01:51,759
six of the wave panels themselves a bunch of brackets as well as joiners

24
00:01:49,680 --> 00:01:55,360
in case you want to bind them together and make cool

25
00:01:53,200 --> 00:01:59,920
geometric patterns on your wall as well as instructions and everything you will

26
00:01:57,520 --> 00:02:03,119
need to mount them before we can mount anything though we need to get a

27
00:02:00,960 --> 00:02:07,200
baseline reading of the current state of the room now there are two main ways we

28
00:02:04,799 --> 00:02:11,440
record audio for our videos either with a lavalier microphone under my shirt or

29
00:02:09,599 --> 00:02:15,360
with a shotgun microphone that's mounted out of the frame and you guys can hear

30
00:02:13,200 --> 00:02:20,480
the difference in how those sound the quick brown fox jumped over the lazy dog

31
00:02:18,239 --> 00:02:22,400
the quick brown fox jumped over the lazy dog

32
00:02:21,680 --> 00:02:28,879
then in order to science it up a little bit we're gonna

33
00:02:26,000 --> 00:02:33,599
switch over to this puppy right here this is the umic one an omnidirectional

34
00:02:31,440 --> 00:02:37,920
condenser microphone from mini dsp that is specifically designed for taking room

35
00:02:35,840 --> 00:02:42,640
measurements like this the software we're going to use is called rew or roo

36
00:02:40,879 --> 00:02:47,920
we just click measure rename it to control no panels

37
00:02:46,239 --> 00:03:00,169
and start you guys are going to want to plug yours

38
00:03:04,159 --> 00:03:10,319
wow it's no wonder the audio's so bad in here even with all the stuff that we

39
00:03:08,400 --> 00:03:14,560
have in the room now i mean it was worse before we are still seeing standing

40
00:03:12,800 --> 00:03:19,200
waves that are lasting as long as about 0.9 of a second

41
00:03:17,840 --> 00:03:25,120
hard to listen to now the goal isn't to turn this place into an anechoic chamber elgato wave

42
00:03:22,480 --> 00:03:29,040
panels would not be the way to do that we just want to cut down on reverb so

43
00:03:26,959 --> 00:03:34,159
the first thing we need to know is how much actual wall and ceiling area there

44
00:03:31,920 --> 00:03:38,000
is in this room so we've got 10 23 times two that's the

45
00:03:36,400 --> 00:03:42,400
ceiling in the floor and then you want to give me those wall measurements we

46
00:03:39,599 --> 00:03:45,599
got 13 carry the one i don't think i have ever carried the

47
00:03:43,840 --> 00:03:51,920
one on camera ah yes there 35 13. i remember to carry the one

48
00:03:49,840 --> 00:03:55,040
forgot all the other basics why don't we target five percent coverage and see

49
00:03:53,920 --> 00:04:01,519
what happens stage two ten percent stage three i mean that

50
00:03:59,519 --> 00:04:04,879
better that better do it yeah

51
00:04:02,959 --> 00:04:10,000
profit seven we have one small problem my control i

52
00:04:08,400 --> 00:04:12,879
said it was with no panels in the room i had these ones sitting here so nobody

53
00:04:11,760 --> 00:04:19,440
touched these we have to i want to keep this scientific boys so these are off these

54
00:04:16,959 --> 00:04:24,639
are off limits this pack though this wasn't in here james

55
00:04:22,400 --> 00:04:27,680
these are a little bit finicky but given that it's something you're only going to

56
00:04:26,000 --> 00:04:32,639
do once not bad actually elgato not bad full

57
00:04:30,560 --> 00:04:36,400
disclosure the reason we have that omnidirectional speaker and the reason

58
00:04:34,479 --> 00:04:41,759
we already know how to use this software is because it is our intention to make

59
00:04:38,479 --> 00:04:43,040
our own acoustic panel product

60
00:04:41,759 --> 00:04:47,759
but that doesn't mean that i'm going to say this is anything but

61
00:04:46,160 --> 00:04:50,560
damn looking pretty good of course the performance is ultimately

62
00:04:49,280 --> 00:04:54,720
what matters more so these aren't the thickest acoustic

63
00:04:52,479 --> 00:04:59,680
panels in the world that cause me some concern the thinner they are the lower

64
00:04:57,280 --> 00:05:04,800
the band of frequencies they will absorb thinner meaning higher frequencies only

65
00:05:01,759 --> 00:05:06,639
but it is two different materials that's

66
00:05:04,800 --> 00:05:11,199
cool because you know you've got a low density foam here and a high air density

67
00:05:08,639 --> 00:05:14,880
foam here plus any time that sound goes through a medium change that's pretty

68
00:05:13,360 --> 00:05:18,000
good for absorption then the setup you don't have to read

69
00:05:16,400 --> 00:05:21,680
the instructions at all at least i hope so because i didn't uh they're really

70
00:05:20,000 --> 00:05:24,560
easy to clip together and then they just friction down into the holes that are

71
00:05:23,440 --> 00:05:29,280
already on the foam not the most secure

72
00:05:27,680 --> 00:05:34,000
i might i might put some adhesive in there if it

73
00:05:31,840 --> 00:05:37,840
was missing critical but if i was going to ceiling mounted i

74
00:05:35,360 --> 00:05:42,479
would on the wall it's probably fine now what are you thinking in terms of

75
00:05:39,919 --> 00:05:47,440
placement do we want to put individual panels just kind of around do we want to

76
00:05:45,440 --> 00:05:52,560
clip them together in kind of geometric shapes and go for large flat surfaces

77
00:05:50,160 --> 00:05:57,039
are we targeting the walls the corners i think that you want to have big

78
00:05:54,400 --> 00:06:01,840
contiguous patches where possible like look between those two blue pipes over

79
00:05:59,199 --> 00:06:05,120
there or right there but then because there are so many different gadgets and

80
00:06:03,600 --> 00:06:09,199
machines in here there's some spots where you don't have much room just do

81
00:06:06,720 --> 00:06:14,319
what you can in those spots a mix okay the clips go in the front just two

82
00:06:11,840 --> 00:06:18,240
kind of flimsy honestly but as soon as you

83
00:06:15,520 --> 00:06:22,880
add a third you've tripled the joins so it's quite a bit more rigid

84
00:06:20,800 --> 00:06:26,319
it's still i mean it's not structural but we're climbing

85
00:06:25,360 --> 00:06:31,120
it can you hold this for me please i'm just going to climb this climate

86
00:06:29,280 --> 00:06:34,880
climate sebastian i mean if the laser level can't support

87
00:06:32,880 --> 00:06:38,720
my weight it's not a good laser level don't go in the lid

88
00:06:36,240 --> 00:06:43,680
uh yeah climate stick tips yeah there's absolutely no reason to put

89
00:06:40,960 --> 00:06:47,199
the foam these foamies on before you hang it on the wall so now we know

90
00:06:45,600 --> 00:06:50,639
that's a tech tip does it look level yeah it looks good

91
00:06:49,199 --> 00:06:53,599
there you are all right

92
00:06:52,240 --> 00:06:56,639
just lean just thrust

93
00:06:59,280 --> 00:07:06,319
i love you wall you're awesome now that we've seen how

94
00:07:03,599 --> 00:07:10,960
much space even one pack takes up on the wall we're rethinking our strategy for

95
00:07:09,440 --> 00:07:16,000
laying them out a little bit so what we're going to try to do is in each area

96
00:07:13,520 --> 00:07:20,720
we want to put panels we're gonna put half as many as would fit now so that

97
00:07:18,400 --> 00:07:27,199
one we're gonna expand by adding another six and then this one here we're gonna

98
00:07:23,520 --> 00:07:30,160
lean a little low so we can go one two

99
00:07:27,199 --> 00:07:33,680
three four more kind of thing when it's time for the second round of testing

100
00:07:38,960 --> 00:07:44,960
i'm good everything's good quick thought james before we assemble a

101
00:07:43,120 --> 00:07:47,919
full frame for the ceiling why don't we just try sticking one to

102
00:07:46,479 --> 00:07:51,440
the ceiling and see if this tape actually holds i think the frame will

103
00:07:50,240 --> 00:07:56,160
hold but what about the foam isn't it just gonna fall off

104
00:07:54,479 --> 00:08:02,720
only one way to find out uh do you mind passing me just one of those single frames uh there's some right there

105
00:07:59,840 --> 00:08:02,720
oh thanks david

106
00:08:03,280 --> 00:08:08,639
yeah there you go okay

107
00:08:06,960 --> 00:08:15,120
there you go there you go bud stretch

108
00:08:11,199 --> 00:08:17,039
the tape is on that side yeah i see it

109
00:08:15,120 --> 00:08:23,440
there's no way this works i am not super hopeful i don't think you

110
00:08:19,840 --> 00:08:23,440
got that one corner closest to you

111
00:08:38,479 --> 00:08:45,279
i guess you're ready to double down now yeah let's do it okay let's get the

112
00:08:42,800 --> 00:08:50,800
ladder does elgato intend for these to go on the ceiling uh i think this is

113
00:08:47,839 --> 00:08:50,800
outside their scope

114
00:08:51,200 --> 00:08:57,440
sorry a little bit ceiling crap

115
00:08:54,959 --> 00:08:57,440
you okay

116
00:08:58,959 --> 00:09:03,600
feels like i inhaled a feather or something do you have a water bottle

117
00:09:02,160 --> 00:09:07,920
here unfortunately no my

118
00:09:05,320 --> 00:09:12,080
lttstore.com water bottle is not here otherwise i'd be fine

119
00:09:09,920 --> 00:09:15,920
the idea is to distribute our five percent as though that's all we have so

120
00:09:14,399 --> 00:09:20,720
we're going to try and get some paneling on pretty much every

121
00:09:18,080 --> 00:09:24,240
surface uh bell over there is mounting free above the eye wash station for

122
00:09:22,240 --> 00:09:27,839
example now obviously before we roll out a bunch

123
00:09:26,240 --> 00:09:31,920
of these next to something like a welding station we want to make sure they have at least

124
00:09:30,399 --> 00:09:36,839
some level of fire resistance see if i can actually

125
00:09:38,000 --> 00:09:44,959
there you go okay we have a fire extinguisher don't worry

126
00:09:42,399 --> 00:09:44,959
it's right there

127
00:09:47,440 --> 00:09:53,279
that's a lot of heat okay wow i'm convinced

128
00:09:51,360 --> 00:09:58,480
should be fine this was one we cut up for a different deployment over on the

129
00:09:55,440 --> 00:10:00,399
podcast set so it's a sacrificial one oh

130
00:09:58,480 --> 00:10:04,560
it stinks but yeah what could go wrong

131
00:10:02,560 --> 00:10:09,600
he sings this while he's holding things over expensive equipment yeah what could

132
00:10:07,120 --> 00:10:13,040
go wrong they definitely work better on the wall

133
00:10:11,200 --> 00:10:18,000
than they do on the ceiling although so far everything we put up has stayed

134
00:10:16,000 --> 00:10:22,320
but you know what's more impressive is everything we've got up here so far is

135
00:10:20,240 --> 00:10:27,839
still cheaper than yeah this thing this kit from auralex

136
00:10:24,600 --> 00:10:30,320
660 dollars for like honestly

137
00:10:27,839 --> 00:10:34,160
i'd be surprised if that single foam type one even performs as well as this

138
00:10:32,079 --> 00:10:38,079
we'll see they're thicker though i think uh not really

139
00:10:35,920 --> 00:10:41,519
fair enough you know what guys we've got 19 more panels to put up and i don't

140
00:10:40,000 --> 00:10:45,120
know about you guys but i'm already noticing a

141
00:10:43,200 --> 00:10:49,360
huge difference we're back on both my 416 as well as my

142
00:10:47,760 --> 00:10:53,839
lavalier microphone you guys can hear the differences between those the quick

143
00:10:51,360 --> 00:10:58,160
brown fox jumped over the lazy dog the quick brown fox jumped over the lazy dog

144
00:10:56,800 --> 00:11:02,880
now i'm just gonna come around here and

145
00:11:00,399 --> 00:11:08,480
we're gonna do a second sweep okay approximately five percent coverage and

146
00:11:05,839 --> 00:11:15,989
start we retested last time i moved away so

147
00:11:18,640 --> 00:11:24,720
dang that's actually i mean

148
00:11:23,440 --> 00:11:31,040
it's not that i can't hear the difference i can totally hear the difference i like i believe it but still

149
00:11:28,800 --> 00:11:34,320
that's really impressive five percent coverage with these things and we went

150
00:11:32,720 --> 00:11:41,040
from a peak of 0.9 seconds at sort of around the

151
00:11:38,480 --> 00:11:47,200
range of my speaking voice all the way to about point six point six and change

152
00:11:44,880 --> 00:11:50,720
i mean you can tell el elgato clearly targeted

153
00:11:48,399 --> 00:11:53,839
human speech frequencies because that's what this product is designed for

154
00:11:52,320 --> 00:12:00,000
because that's where we see the biggest improvement right in that 400 to

155
00:11:56,880 --> 00:12:02,320
approximately 1500 hertz range

156
00:12:00,000 --> 00:12:06,000
wow even up to around three kilohertz it's like pretty darn good like how does

157
00:12:04,399 --> 00:12:10,639
it sound better to you if i'm hosting a video okay david we're we're building

158
00:12:08,399 --> 00:12:13,519
this computer this is a super cool build by the way make sure you're subscribed

159
00:12:11,760 --> 00:12:17,120
so you don't miss this one sounds way better

160
00:12:14,959 --> 00:12:21,600
wow that's awesome let's put up a few more let's get that

161
00:12:19,040 --> 00:12:25,120
big flat spot there dealt with i don't know maybe like you know a strip down

162
00:12:23,680 --> 00:12:28,800
there and then we'll we'll call it yeah

163
00:12:27,519 --> 00:12:34,160
everything's been going really well so far but david i just noticed something i thought i was kind of imagining it

164
00:12:31,680 --> 00:12:39,519
before but look at this there's some inconsistency in the color of the

165
00:12:36,480 --> 00:12:41,760
foam so if this was a major aesthetic

166
00:12:39,519 --> 00:12:45,839
thing for you um just be aware like this one's basically

167
00:12:43,920 --> 00:12:50,240
silver compared to this one which is more like black do you see that yeah i

168
00:12:47,920 --> 00:12:54,079
didn't i wasn't sure until i saw these two next to each other like they're a

169
00:12:52,480 --> 00:12:58,399
little all over the place but if you buy one pack i would imagine they're closer

170
00:12:56,079 --> 00:13:02,720
at least without any clear objective we kind of put some more on until it looked

171
00:13:01,200 --> 00:13:09,120
nice i think it looks pretty nice in here and we ended up with a total of 210

172
00:13:06,480 --> 00:13:13,760
square feet which it's kind of looking dangerously close

173
00:13:10,959 --> 00:13:18,639
to 69 percent hold on let's check it 10 divided by 35 30.

174
00:13:16,680 --> 00:13:23,440
5.9 5.9 one short but that's okay

175
00:13:21,040 --> 00:13:28,880
let's go ahead and run our second our third rather our third

176
00:13:26,639 --> 00:13:34,079
sweep actually wait i forgot to do this again the quick brown fox jumped over

177
00:13:31,360 --> 00:13:38,160
the lazy dog the quick brown fox jumped over the lazy dog all right okay now

178
00:13:36,880 --> 00:13:41,600
let's do our sweep i i think it's actually better again i could be wrong i

179
00:13:40,000 --> 00:13:46,240
could be imagining it that is why we have objective

180
00:13:43,519 --> 00:13:52,399
measurements we added another six boxes giving us approximately

181
00:13:49,760 --> 00:13:58,079
5.9 coverage and let's go ahead and start it guys ready

182
00:13:58,079 --> 00:14:02,959
wow big improvement again check this out

183
00:14:02,160 --> 00:14:10,240
guys we just shaved off another anywhere from

184
00:14:06,959 --> 00:14:13,040
0.1 to 0.2 of a second in the range that

185
00:14:10,240 --> 00:14:17,199
we care about which is kind of in here this is honestly way better than i

186
00:14:14,880 --> 00:14:21,040
expected like this is completely usable now i we could keep putting on panels

187
00:14:19,519 --> 00:14:27,120
but honestly i just don't really feel like it's necessary we can take these panels we can treat other areas in the

188
00:14:23,920 --> 00:14:29,440
studio i you know what you guys might

189
00:14:27,120 --> 00:14:33,040
look at the cost of this 2100 and you might think whoa that's a lot of money

190
00:14:30,880 --> 00:14:37,279
and it is but compared to what normal acoustic treatment panels cost from

191
00:14:34,560 --> 00:14:41,760
specialty vendors they are darn freaking reasonable remember this is a big room

192
00:14:40,079 --> 00:14:46,320
now obviously you could save a lot of money doing it yourself with rock wool

193
00:14:44,000 --> 00:14:49,440
or ultra touch batting and a wooden frame

194
00:14:47,199 --> 00:14:54,079
absolutely but considering the overall package here i think Corsair's got

195
00:14:51,680 --> 00:14:57,680
excuse me elgato has a winner on their hands

196
00:14:55,600 --> 00:15:01,839
