Household appliances and consumer products should aim to be exceptionally quiet while delivering high-quality product.

Acoustic measurement methods are therefore used both in the development phase and in the maintenance and servicing of devices and equipment, and vibration analyses are carried out to localize noises and optimize products.

Our various Acoustic Cameras, whether AC Pro systems or all-in-one sound cameras, are used in the identification and analysis of noise sources, troubleshooting, and sound design optimization. By quickly identifying these noise sources and providing solutions, manufacturers and developers can save time, adapt their products more quickly to customer requirements, and effectively eliminate potential defects.

In product development, the Acoustic Camera also helps to ensure that the next generation of household and leisure appliances has a first-class sound design. This improves the customer experience and increases the appeal of the products. Acoustic maps help identify where manufacturers need to target to reduce sound emissions from appliances, machinery and equipment and comply with regulatory limits. The areas of application are as diverse as the products themselves: Mobile or stationary, small or large – sound measurements can be carried out on a wide variety of equipment.

Acoustic Measurements with the Soundcam Mikado

A 3D object was simultaneously scanned in real time using gfai tech’s Soundcam Mikado and calculations were made using gfai tech’s advanced power beamforming algorithm. This enabled the acquisition of a detailed “acoustic fingerprint” of the measured object with only one measurement.

The high quality of the acoustic maps is due to both the DynaBeam method and the power beamforming algorithm, which were used in conjunction with the array’s high microphone density. The resulting images are an impressive example of state-of-the-art acoustic measurement technology and its application in industry.

The Acoustic Camera can find faults resulting in variations in the soundscape, without depending on the disposition of quality assurance (QA) staff. Two acoustic images can be placed side by side in NoiseImage to perform a simple comparison of nominal and actual values. The same value range is applied to both images with the click of a mouse button. Any variations become obvious and the visual presentation also reveals where exactly the fault is located.
