Why are we excited about becoming the NZ Distributor for this tool? Because it can “see sound!”
And that is enough to remind me of the amount of time I spent over the years with a screwdriver, stethoscope and fuel hose finding faulty bearings, water pumps and tuning E49 six pack Webers, and that's enough for me to rate it.
I have been walking around home with this demo tool for a while now pointing it at anything and everything, I didn't get the reaction I hoped for on one occasion but I have learned from that and am allowed back in the house again. However, while out in the shed I refocused and confirmed the exact location of the leak in the woodsplitter tyre, the point of leakage on the compressor hose fitting in the workshop and where the boost pressure leak was on the A3.
Almost all of those results were enough to impress me and I am already looking forward to using the TD2e to solve future problems.
If I think back to recent cases, it would have been great to have the TD2e when solving a hard to find AC system leak and would definitely have solved a questionable brake tester bearing that was replaced “just in case”.
I don't restore classic cars anymore but pairing the TD2e up with the audio signal generator on the seat of the vehicle and walking around the outside looking for signs of seal leakage would have been gold back then. Potentially every vehicle coming out of the panel shop after body work could benefit from that test.
What is Acoustic Imaging anyway?
Limitation of Human Perception
Seeing sound is the simple answer and while it will confirm our suspicions about sounds in the range of the human ear (20Hz to 20KHz) it will also provide clear images of noise right up to 100KHz offering increased early wear and noise detection solutions through the inaudible sound spectrum.
How does it work?
The TD2e presents sound on screen as an image with on board features to help accurately solve a wide range of automotive and engineering workshop issues.
Microphone Array: Simultaneously captures sound signals from multiple sources to enhance spatial accuracy.
Beamforming Algorithm: Focuses on sound sources from specific directions,filtering out environmental noise.
Acoustic Image Overlay: Displays sound source locations as a heatmap over the image.
Low-Latency Rendering Engine: Enables near-instant response, ideal for continuous inspection scenarios.
Beyond What's Audible
The FOTRIC TD2 acoustic imaging camera can detect not only audible sound (20Hz–20kHz), but also high-frequency ultrasonic signals that are beyond the range of human hearing.
This means it can easily capture things like:
Compressed Air System Leaks
As gas leaks emit high-frequency turbulence noise, the TD2 can quickly detect even the smallest leaks in compressed air pipelines.
Vacuum System Leaks
The TD2 precisely captures subtle leak sounds in vacuum systems that human ears cannot hear, enabling fast leak localisation without contact or damage to equipment.
Loose Joint Vibration During Operation
The TD2 detects abnormal high-frequency sounds caused by loose screws while equipment is running. It visualises and pinpoints the issue in real time without requiring a shutdown.
Tyre Air Leaks
The TD2 quickly visualises and locates tyre leak points without the need for soap spray—precise, efficient, and easy to use.
Unique Features
Acoustic Image Focus
Combines adaptive dynamic noise reduction alogorithms to achieve focused localisation of sound sources
Source Mode Switching
The TD2 Kit supports multiple image modes, including single source, multi source and holographic views allowing users to adapt to varying noise complexities and detection targets on site.
Sound Pressure Level Measurement
By combining acoustic images with dB-level datta output, it is well suited for locating and diagnosing a wide range of industry sound sources. This enhances the intuitiveness, efficiency and safety of inspections
The TD2e acoustic imaging camera comes as a kit including a spare battery, rugged case, extended warranty and for field work, a tool holster.
