Our Acoustic Camera Cuts Time and Cost

In today’s fiercely competitive market, speed is as crucial as quality. Our acoustic camera is the pivotal tool that helps you achieve both. By visually depicting noise sources, development teams can immediately see where issues lie and swiftly implement solutions. This eliminates the need for lengthy iterative tests, traditionally consuming time and resources.

Furthermore, by detecting noise issues early on, you can ensure compliance with noise regulations, thus avoiding costly retrofits often discovered just before market launch. Not only does this contribute to cost-effectiveness, but it also enhances the end product by ensuring it meets customer expectations for comfort and quality.

Acoustic Optimization of Household Appliances

Development engineers need to understand with high confidence how multiple, closely located sound sources contribute to the overall sound pressure level. Across the entire relevant frequency range, the acoustic image with high spatial resolution and wide dynamic range reveals dominant sound radiation from the electric motor in the handle area, followed by the dust separator and the intake noise from the nozzle. This information enables the implementation of effective technical solutions to achieve a required target sound level.

Compliance with Noise Limits in Machining Processes

Machine tools cover a wide operating envelope in material processing. Certain combinations of tool, speed, feed rate, and material can result in excessive sound pressure levels during machining. Acoustic images precisely locate areas where sound insulation improvements of the enclosure are needed, allowing machining equipment to operate at peak performance while meeting regulatory requirements.

Sound Design of Vending Machines

The coin dispensing noise from a cash recycler may disrupt conversations with bank customers. Manufacturers of these machines strive to design their products to be psychoacoustically pleasant. This requires a fundamental understanding of the sources of sound radiation. Acoustic images highlight the main locations at the dispensing tray and an opening in the bottom plate (reflection) on the front side as well as at the ventilation grille and the maintenance door on the reverse side.

Optimal Installation of Machines

The perceived noise around machining equipment is dependent on its installation environment. Room corners, low reflective ceilings or hard surfaces are significant causes of elevated sound pressure levels. The acoustic image shows a dominant reflection from a glass front at a work safety-relevant observation point. The root cause is due to sound radiation through an opening at the top of the machine tool. This information aids in decision-making for potential technical solutions – whether to directly modify the machine or implement room acoustic measures such as absorbent curtains.

Get the Acoustic Image delivered within seconds

Through cloud computing and artificial intelligence, acoustic images are made available on a mobile device for immediate analysis.
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.

What does a Sound Scanner Kit contain?

A Sound Scanner Kit priced at €5.490 comes with the following components:

  • 1 sensor of your choice
  • 1 mobile device (tablet or smartphone)
  • 1 calibration speaker
  • 1 tripod
  • 1 laser distance meter
  • 1 carrying case
What distinguishes Public and Private Cloud infrastructures for computing acoustic images?

Public cloud users send their data to the cloud, relying on an internet-capable data connection. In contrast, private cloud users transfer data to a local high-performance laptop using a local WiFi connection.

The computation time for acoustic images is generally comparable between these configurations. The private cloud package is ideal for users without an internet-capable data connection at the measurement location who prefer to analyze results on-site.

Can I use my own mobile devices?

The camera characteristics of the provided mobile device are measured and compensated. While the mobile app can technically be installed on other Android devices (Android operating system version 10.0 or higher), conducting measurements with such devices is not recommended.

This is because the localization accuracy cannot be guaranteed due to missing information on the camera module. However, any compatible mobile device can be used for importing and analyzing measurement data recorded with the provided mobile device.

Can I use my own laptop?

The Private Cloud configuration includes a dedicated, pre-configured high-performance laptop for efficient computation of acoustic images with minimal response time.

Please note that we do not support the installation of the compute service on other equipment.

What additional costs arise besides the annual software license?

For Public Cloud users, an internet-capable data connection is required, and additional costs for metered data connections (e.g., mobile data) should be considered.

What is the average recording time for a measurement?

In many situations, successful localization of acoustic sources can be achieved with a recording time of only 5-10 seconds per measurement.
