Sound Scanner P50

The Sound Scanner P50 acoustic camera is designed to locate medium and high frequency sound sources. Thanks to its size with a measuring diameter of 50 cm, the camera can be easily used in small spaces. With the increased rotational speed of the camera's measuring element, it also enables accurate measurements of moving objects..


Sound Scanner is a new type of acoustic camera created by the Austrian company Seven Bel. The innovative system consists of the following elements:

  • sensor unit
  • mobile device
  • software
  • cloud infrastructure
  • tripod

The sensor is mounted on the tripod and set into a rotating motion during measurement. The sensor design, comprising high-quality materials such as carbon, ceramic and aluminum, is robust and operational only with a few quick and easy moves. The sensor is lightweight and compact, and can therefore be taken along for any situation.


Data processing works as fast as the setup. After each measurement, the mobile app transmits the collected data to our high-performance servers. Within seconds you receive acoustic images in superior image quality. Benefit from a massively simplified workflow for measuring and analyzing your sound events and share the results with your colleagues, partners or clients in the form of automatically generated reports.


  • high-quality measurements
  • quick setup
  • exceptional mobility
  • superior price-performance ratio
  • simple operation

With the patented innovation of a moving sensor Sound Scanners are able to simulate up to 480 microphone positions on a circular area while using only five built-in microphones. Comparable acoustic cameras are normally equipped with about 100 microphones. This advantage has significant impact on the measurement quality. The unique mobility and handling and high-quality measurement results make the Sound Scanner P50 a modern high-performance measurement device that can be used and transported easily. No Laptop, power adapter or data recorder needed – more space for other things.
