1. 0:00This is the Faultrick TD2 E Acoustic
2. 0:03Camera and it's going to be a
3. 0:04game-changer for automotive technicians.
4. 0:07And in this video, we're going to look
5. 0:08at some obvious ways to make the most of
6. 0:10this tool plus some very creative ways
7. 0:12of finding problems you might not have
8. 0:14thought a camera like this would help.
9. 0:17Okay, so this is an acoustic camera and
10. 0:21what makes this one quite interesting is
11. 0:24the price. So, acoustic cameras have
12. 0:26traditionally come in with a price tag
13. 0:28of around $10,000. This is much, much
14. 0:31less. Faultrick have sent us this in
15. 0:34return for making a video and we also
16. 0:36have some links in the description
17. 0:38below. You can go and check that out and
18. 0:41see if it's something that you want to
19. 0:43go for. So, this is the TD2 E version.
20. 0:46There is a slightly more expensive
21. 0:47version which I am also interested in
22. 0:49because it has a HDMI port on the top
23. 0:51which this budget version doesn't have.
24. 0:53They also have a phone version of it as
25. 0:56well. So, how it works, we've got 64
26. 0:59microphones strategically placed on the
27. 1:02front of this camera with the actual
28. 1:04camera sensor in the middle there. We
29. 1:07also have a light for, you know, dark
30. 1:09places which you're going to be using in
31. 1:11a minute. And then on the screen here,
32. 1:13you can see that it's picking up all the
33. 1:15different noises in the workshop. Now,
34. 1:18what's quite interesting about this is
35. 1:20it works for frequencies between 2 kHz
36. 1:23and 100 kHz. So, it will even pick up
37. 1:26very sensitive things like me breathing.
38. 1:31So, traditionally these have been used
39. 1:33by big industrial companies for finding
40. 1:36leaks in factories and power plants and
41. 1:40things like that. And I'm going to show
42. 1:42you today a couple of tests. So, let's
43. 1:44get straight on probably the most
44. 1:46obvious one to look at, a mechanical
45. 1:48noise.
46. 1:49Okay, so the camera has a couple of
47. 1:52modes and the startup mode is in a
48. 1:54single source. So, what that does is it
49. 1:57picks up the loudest noise and and kind
50. 2:00of shows you where it is. You can see on
51. 2:02the right-hand side as well, it gives a
52. 2:04scale of the frequencies that are being
53. 2:06picked up. So, you can see that most of
54. 2:08the noise is being picked up at the
55. 2:09minute are in that lower frequency
56. 2:11range. Now, for diagnostics, I think a
57. 2:14good thing to do would be to start with
58. 2:16all sources and now you can see that it
59. 2:18picks up all of the noises around the
60. 2:21vehicle. So, what we've got on here, so
61. 2:23hopefully you can hear it, is a bit of a
62. 2:25ticking noise. The back wheels are
63. 2:27spinning at the minute. And when it's in
64. 2:30motion, there's like a ticking noise
65. 2:31coming from the back.
66. 2:33So, as we walk under the vehicle, you
67. 2:35can see that there's all sorts of
68. 2:36different noises being picked up from
69. 2:38the engine area.
70. 2:40And as we walk down the back,
71. 2:43we can actually see there's a hot spot
72. 2:45there right in the middle
73. 2:47being picked up around the prop shaft
74. 2:49area. So, what we can do now as well is
75. 2:50just use the light. So, we switch the
76. 2:52light on.
77. 2:55And here we are. So, you can almost like
78. 2:57pinpoint where the main noise is coming
79. 3:00from. There are other noises down here
80. 3:02as well. So, if we point this at the at
81. 3:04the wheel area, you can see things being
82. 3:06picked up from the brakes.
83. 3:08And once you kind of get close into
84. 3:11where the noise is,
85. 3:13switch it to single source,
86. 3:16and it will help pick up where that
87. 3:18loudest noise is coming from.
88. 3:20So, all I have actually done here is is
89. 3:22put a
90. 3:23a cable tie
91. 3:28around the prop shaft and it's just
92. 3:30ticking along on there on the um fuel
93. 3:32tank there.
94. 3:34So, although that is quite an obvious
95. 3:36noise to find,
96. 3:38it just shows you how quickly this thing
97. 3:40can pinpoint those noises and use the
98. 3:44different features that you've got on
99. 3:45there like all sources and move down to
100. 3:48single source to identify where it's
101. 3:50coming from.
102. 3:52So, sticking with the mechanical noise
103. 3:55theme, we're going to induce a noise on
104. 3:57this engine now. Now, I'm going to first
105. 4:00do a shot of the engine with no faults,
106. 4:04and then we're going to install a fault
107. 4:05to make the fuel system howl, and see if
108. 4:08we can identify where that noise is
109. 4:10coming from.
110. 4:11Okay, so we've got the camera trained
111. 4:13onto the engine, and we're using the
112. 4:16MultiSource, which is picking up the
113. 4:19different sources of noise, and just
114. 4:21showing them where they are. Um what's
115. 4:23quite interesting is what happens when
116. 4:25we put the fault on this vehicle. So,
117. 4:29all I'm going to do is disconnect the
118. 4:30high pressure pump, and that puts the
119. 4:33fuel system in into a default high
120. 4:35pressure mode, so it runs at maximum
121. 4:37pressure, and we get this kind of
122. 4:38squealing noise. Let's see what happens
123. 4:40on the camera.
124. 4:41So, at the minute you can see we've got
125. 4:44some noises kind of around here,
126. 4:47but it's it's moving around a bit.
127. 4:50Of course, it's quite noisy while the
128. 4:52engine's running.
129. 4:53If we just take that off,
130. 4:57hopefully you can hear that now. We've
131. 4:59got a definite noise, and it's picking
132. 5:01it up a little bit further up.
133. 5:04Before we were having like noises
134. 5:06flipping around here, but now we've got
135. 5:08a definite noise locked on here, and if
136. 5:12we put it onto single source mode,
137. 5:17there it's picking up that noise just
138. 5:20from that point there.
139. 5:21So, what we've actually actually got
140. 5:23down here is the the high pressure pump
141. 5:24here, which I've disconnected, and then
142. 5:27on the bottom of the high pressure pump
143. 5:30there's a that metal pipe that goes into
144. 5:31the rail, and that pipe at the end of
145. 5:34that pipe is creating a lot of noise,
146. 5:37and that's what the camera's picking up.
147. 5:39So, if we just go back to that all
148. 5:40source mode,
149. 5:43we can see that down there is where that
150. 5:45the most of that noise is being picked
151. 5:47picked up. The high pressure pump itself
152. 5:50is also showing up a bit noisy.
153. 5:53If we go to single source down here,
154. 5:57you can see that around that high
155. 5:59pressure pipe is where that noise is
156. 6:01being
157. 6:03picked up the most.
158. 6:05We can also see the high pressure pump
159. 6:07is a little bit noisy as well.
160. 6:10So, I think this would also be really
161. 6:11good for finding noises on the
162. 6:14auxiliary drive belt when you've got
163. 6:15bearing noises and squeals and things
164. 6:17like that. Um I suppose especially if
165. 6:20the access is quite difficult. Now we
166. 6:22start to get into the area that really
167. 6:24stretches the capabilities of this tool.
168. 6:27Not so much stretch the capabilities,
169. 6:29but use them, okay? Now, just to put
170. 6:31this into perspective, we said the
171. 6:33camera was effective between 2 kHz and
172. 6:37100 kHz. Now, humans uh hearing is
173. 6:41really only suited for low frequencies,
174. 6:44and I'm going to show you what that
175. 6:45means now. So, I've got a um
176. 6:48it's a it's just a frequency generator
177. 6:50app, and it's set to about 2 kHz of
178. 6:53sound. So, if we play that noise now,
179. 6:58most people should be able to hear that.
180. 7:00Sorry, headphone users. But, what I'm
181. 7:02going to do now is increase that
182. 7:03frequency, okay? And now listen what
183. 7:06happens.
184. 7:07This will really depend on your age as
185. 7:09well, whether you can hear it all the
186. 7:10way up.
187. 7:17Okay, so that's 5,000 Hz. I can still
188. 7:19kind of hear that okay.
189. 7:23Now we're at 8,000 Hz, and it's getting
190. 7:26getting loud. Well, it's not getting
191. 7:27louder, it's just getting a bit harder
192. 7:29to hear. There's 10 kHz.
193. 7:32Uh we get to about 14, I can
194. 7:35just hear it very very very faintly in
195. 7:38the background. Younger viewers will
196. 7:40probably be able to hear that. So, if we
197. 7:42play this noise to the camera, let's see
198. 7:46what happens.
199. 7:49We can see that it's being picked up.
200. 7:50What I'm looking at really is this scale
201. 7:52on the side there. And if we increase
202. 7:54that up,
203. 7:57what we can see is that that
204. 8:00frequency, the noise of that frequency,
205. 8:03is showing high there, okay? So, that
206. 8:05goes up to 10.
207. 8:08We carry on going up. It's still picking
208. 8:09up a bit of noise there. But I think
209. 8:11actually beyond this, the phone
210. 8:14this app isn't actually creating that
211. 8:16noise.
212. 8:17It drops out at about 15 kHz.
213. 8:21So, why am I showing you that? There are
214. 8:23many noises on these vehicles that are
215. 8:25just beyond the hearing capability of
216. 8:28humans, but this thing can see it. One
217. 8:30of those things being leaks. So, what
218. 8:32I'm going to do now is induce an intake
219. 8:34leak on this vehicle and see if we can
220. 8:36find it.
221. 8:38Okay, so we've put an air leak fault on
222. 8:41this engine, and that would be something
223. 8:44that would coincide with a lean running
224. 8:46fault or a fuel mixture fault.
225. 8:49So, if we just kind of scan around the
226. 8:51engine here,
227. 8:53put the light on. What we're really
228. 8:54looking for is is I suppose along the
229. 8:57pipes in the areas of the intake
230. 9:00manifold, and we can see here that we've
231. 9:02actually got a a hot spot
232. 9:06right in the middle there
233. 9:08on that pipe.
234. 9:10And if we zoom out a bit and then just
235. 9:12go to
236. 9:14single source,
237. 9:16you can see that it's
238. 9:18picking up that area as a source of
239. 9:22high noise.
240. 9:25So, that could be super useful for these
241. 9:28petrol engines with really complex
242. 9:31intake systems or the diesel engines
243. 9:34that tend to have lots and lots of
244. 9:35vacuum now. This should be able to
245. 9:37pinpoint those leaks quite easily. I
246. 9:39know we have the smoke tester that can
247. 9:41be quite useful. However, sometimes
248. 9:43these faults only appear while the
249. 9:45engine is running. So, being able to put
250. 9:47the engine into that active state and
251. 9:50then check around for those leaks is
252. 9:52really quite useful. So, all we did
253. 9:54there was remove the seal off that
254. 9:56crankcase breather hose to induce that
255. 9:59leak. So, this next test is potentially
256. 10:02my favorite test yet a little bit
257. 10:04creative. Now, what we need to think
258. 10:06about is when we've got things that are
259. 10:09active, you can see that when I point
260. 10:11the camera at the computer and stuff
261. 10:13over here, there's not a lot of noise
262. 10:15going on, but it's picking up all sorts
263. 10:18of stuff. You know, we've got this
264. 10:20LED light here. It's picking up noise
265. 10:22from there. So, potentially, it could be
266. 10:26picking up those high-frequency noises
267. 10:28generated by electronic items when
268. 10:31they're active.
269. 10:33Battery drain faults. So, when we look
270. 10:36inside this vehicle, we can see there's
271. 10:39lots of noises coming from around the
272. 10:41instrument cluster and dash areas and
273. 10:44that is with the ignition on.
274. 10:46Also, looking around the center console,
275. 10:48we can see there's lots of activity and
276. 10:52there's a good three or four control
277. 10:53units down in that area.
278. 10:55Just while I'm sat in here, it's just
279. 10:57made me think of a rattle that I've got
280. 10:58on my car coming from the headrest or
281. 11:01headrest area, how you should say. This
282. 11:03would also be great for finding that
283. 11:05problem.
284. 11:06And you know, if we come down to the
285. 11:08rear of the car, we can see there's a
286. 11:10bunch of control units there and they're
287. 11:12all making lots of noise that we just
288. 11:15can't hear.
289. 11:16What's also quite impressive is I've
290. 11:18been filming for about an hour now and
291. 11:20we're probably not even at the halfway
292. 11:22point on the battery.
293. 11:23So, that was the Photo Trick TD2E
294. 11:26acoustic camera. Pretty impressive bit
295. 11:28of kit. Let us know down in the comments
296. 11:30if there are any other things that you
297. 11:31think it would useful for. In the
