Head Acoustics has developed the Head Visor VMA V acoustic camera to pinpoint sound sources. Much like using an infrared camera with heat sources, the Head Visor is a simple point-and-shoot affair that displays the exact location of sound sources over a real-world image. This allows users to find where noises are coming from in an object or room for further noise mitigation, soundproofing, or acoustic tuning.
Locating the exact source of sounds in a noisy environment such as a vehicle can be difficult. The sounds can blend together the farther one’s ears are from the source, making locating them a tiresome task of putting one’s ear next to every part of an object. Also, noises at certain frequencies, such as low bass, can be troublesome to locate because human ears are not as accurate in locating them.
The Head Visor VMA V acoustic camera accurately pinpoints where sounds are emanating from by using 60 MEMS microphones arranged across a 30 cm diameter array or 120 microphones arranged across a 1 meter diameter array. The 60-microphone array has a frequency range of 980 to 20 kHz while the 120-microphone array has a range of 250 to 20 kHz. Sounds are sampled at a rate of 48 kHz.
The Head Visor 6 software uses beamforming and artificial intelligence algorithms to precisely identify sound sources and show them on the 1,024 x 600, 7-inch capacitive touch display over images captured by the 1,280 x 800 30 fps camera. The raw sound data can also be saved for further post-processing and analysis.
A variety of licensing models are available, from a basic Head Visor Snap license to a full-featured Head Visor complete license that enable live recordings, data export, offline analysis, and more.
The 60-microphone camera setup weighs 6.4 pounds (2,900 grams) while the 120-microphone setup weighs 8.4 pounds (3,800 grams). The camera runs up to 2 hours between charges on its 4 Ah, 59.2 Wh battery. A range of ports and input/outputs are provided for connectivity to vehicles, tripods, data collectors, and more, and readers using the Head Visor VMA V acoustic camera should buy a pair of top-notch headphones for monitoring their recordings (like this one on Amazon).
New HEAD VISOR VMA V Acoustic Camera and Software
13 December 2023
Acoustic cameras can determine the position of sound sources in sound fields with a technology called beamforming. The new HEAD VISOR VMA V Acoustic Camera and HEAD VISOR 6 software constitute a unique combination of features, making it a preferred choice for professional users.
The HEAD VISOR VMA V Acoustic Camera
The lightweight and modular new HEAD VISOR VMA V offers extremely high levels of convenience and quality results, as all relevant settings can be made on the device, which can still easily be held in the hands over a longer period without fatigue. Of course, it can also be used with a standard camera stand.
HEAD VISOR VMA V is intuitive and efficient to operate, featuring a 7” multi-touch display and four control buttons that enable instant and highly precise results. All relevant functionalities of the HEAD VISOR Software are available on the handheld unit in real-time. The 30-cm-body integrates a depth camera for distance measurement and 60 microphones for close-up applications, for example, in a car interior. It is easily extendable with ten spiral arms, adding another 60 microphones and creating an array with a diameter of 100 cm. With this array, HEAD VISOR VMA V achieves a higher resolution and makes sounds visible down to a frequency of typically 250 Hz. HEAD VISOR VMA V allows users to visualize sounds at a wide range of distances, starting from only 30 cm.
The HEAD VISOR 6 Software
The HEAD VISOR 6 Software delivers the perfect user interface for beamforming and acoustic camera applications. It is a powerful and easy-to-use tool that combines functions such as recording, playback, analysis, and reporting in one package. It also features unique artificial intelligence algorithms (like neural deconvolution) to increase dynamics and spatial resolution. Thanks to the sophisticated data processing, the system can keep the raw data, so users can make changes even after the measurement.
Applications
Applications range from troubleshooting through analyzing and optimizing sounds to leak detection and visualizing acoustic weak points. It can be applied on test benches, in vehicles, in wind tunnels, or for environmental measurements.
Licensing
Users can select between four license models, ranging from the HEAD VISOR Snap license, which lets users take a snapshot of the object under investigation and export it instantly, to a full license that grants access to the whole range of features our HEAD VISOR system offers.
