The Sound Scanner:
Precise, Intuitive & Mobile

The Sound Scanner is the first acoustic camera based on the “Sound Field Scanning” technology. It can locate sound sources in the frequency band from 125Hz to 44kHz and delivers high-quality acoustic images directly to a mobile device for analysis.

The Next-Generation
Acoustic Camera

In “Sound Field Scanning,” the incident sound field is sampled with just five microphones; however, a superior algorithm represents 400 virtual microphone positions. We process only a fraction of the data compared to traditional acoustic cameras, that’s why we can do it without complex hardware. We compute the acoustic image directly in the cloud, and visualize the results using mobile app technology.

Unlimited Mobility: Indoor & Outdoor

The Sound Scanner offers unmatched mobility and simplicity. Lightweight, compact, and handy, it can be effortlessly transported—from construction sites to testing labs or anechoic chambers.

Thanks to its wireless, battery-powered components with up to 6 hours of runtime, it is ideally suited for outdoor use. Experience limitless mobility, both indoors and outdoors—on the go in cars, trains, or airplanes.

Check Measurement Results on Mobile Devices

Technically Speaking: a Class of Its Own

The Sound Scanner is in a class of its own, thanks to its unique Sound Field Scanning technology, which delivers precise measurement results across the entire time and frequency spectrum with a dynamic range of over 13dB and high noise sensitivity.

Paired with our modular system and a measurement surface of up to 2.5m in diameter, it enables exceptional spatial resolution and localization accuracy at low frequencies starting from 125Hz.

 

Modular & Versatile

The Sound Scanner redefines flexibility. With a system that covers frequencies ranging from 125Hz to 44kHz, you are equipped for all applications, in the audible range and ultrasound. Thanks to its modular design, you can add additional sensors for extended frequency ranges at any time.

Precise Acoustic Image
Within Seconds

Through cloud computing and artificial intelligence, acoustic images are made available on a mobile device for immediate analysis.
In real-time, precise, and across the full frequency and time range.

Scan the Sound Field

Put the sensor in motion and scan the sound field. The mobile device controls the measurement process and sends the data to the cloud.

Get the Image

In the cloud, the acoustic image is calculated by our patented algorithm. Alternatively, it can be processed on a high-performance laptop on-site.

Analyse the Results

The acoustic image is sent back to the mobile device for analysis. Detailed analysis is conducted on a laptop using special software features.

Post-Processing without Limits

In addition to the Acoutect app on the mobile device, Sound Scanner users can utilize comprehensive functions and features in post-processing. Our software engineers have developed customized features for a variety of special applications that are unmatched in the market.
