The Innovators
of Acoustic Cameras

Seven Bel developed the Sound Scanner, a novel acoustic camera that easily locates sound sources. This solution simplifies the time-consuming search for the source of the sound and sustainably improves optimization processes.

About Seven Bel

Seven Bel was founded in 2018 and has developed the Sound Scanner, a device that visualizes and locates sound quickly and easily. This new technology for acoustic cameras is based on a sensor that scans the sound field on a circular surface.

The technology is easy to use (operation via mobile app), fast to set up (first measurement results incl. setup time for the measurement system in less than 3 minutes), mobile (no large build-ups or cables needed), and provides high-quality measurement results even for low-frequency sound events.

The company name Seven Bel is derived from the sound level 70 decibels (or 7 Bel), the limit above which noise can be potentially harmful to human health in the long term. Seven Bel’s mission is to help engineers develop more silent products or to efficiently support with noise abatement activities.

Often the origin of sound is difficult to determine or not where you think it is. With the Sound Scanner, our acoustic camera, it can be detected quickly and easily. Time that is often spent in lengthy cause research or tests can be saved.

Making sound visible and displaying it on images makes it easier to implement high-quality technical solutions, thereby making products and processes quieter and contributing to overall sound reduction.

Our Vision

Humans possess five senses to interact with their surroundings, using these to gather information for decision-making. Assessing and visualizing sound is crucial for accurate insights and quality technical solutions. Our aim is to make sound imaging self-evident in both industrial and personal settings. A notable fact: exposure to seventy decibels or higher can harm human health. We’re committed to lowering noise levels in products and processes for the well-being of people and the environment.
