The sound camera visualizes the location(s) of sound and overlays that on a B&W visual camera image taken at nearly the same time. The device has a maximum resolution of 3.4 degrees, with a beamwidth (or point spread function) that inversely decreases with frequency, and with a beamwidth of ~8 degrees at 10 kHz. The Field of View (FOV) within the search area is ~70 degrees x ~40 degrees. The device records 48 kHz audio from a 16-microphone array for 0.2 seconds to collect audio data to be imaged. The device has a frame rate and data collection interval up to 3 Hz with a 0.7 second visualization lag but varies some depending on user settings.

Applications for such a device are typically high frequency leak detection. An example of it imaging sound from a sprinkler and from an air can are demonstrated in the screenshots. The device highlighting the location of a cricket is shown as well. A possible use case is the Line Of Sight (LOS) can be determined for some very high frequency bird calls (owls would be too low frequency), see photo of tree as an example. The package comes with an acoustic array, keyboard, cables, and tablet with necessary software. The package is easily assembled into a mobile sound imaging system with hand grips and mounting system provided. A hardened case is also provided for ease of transport when not in use.

The acoustic camera is designed to need as minimal of user interaction as possible. The acoustic camera boot time is ~1 minute. Six additional keys are provided to control sensitivity, and another to shut down the device. Increasing sensitivity slows the refresh rate but increases the range of frequencies imaged. Which frequencies being imaged are demonstrated in a subplot to the right of the acoustic image, and sounds being imaged are those bounded by red dashed lines. The device automatically adjusts to image the most prominent components of the acoustic spectrum observed during sampling.

Other acoustic imagers/sound cameras are usually significantly more expensive, but this was avoided through careful use of computing and software algorithms.

Tripod is not included but supports the standard 1/4-20 interface used with most tripods. A tripod is highly recommended with its use!

Note, this description has been updated for the new model, some visuals use the original model's software imagery, which has since been improved. The device may have been lightly used for testing/calibration purposes. Current model being sold has a black mounting system. Some cosmetic issues from mounting system's printing may be apparent as production processes are still being improved but does not affect its technical operation. If a specific color is required contact for specialized build.
