Sound Scanner P132

The Sound Scanner P132 has been specially developed for applications in the fields of engineering, building acoustics and environmental noise. Due to the sensor size with a measuring diameter of 1.32 m, even low-frequency sound events can be precisely visualised.

The Sound Scanner is a new type of acoustic camera developed by Seven Bel. The innovative system includes the following components:

  • 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 aluminium, 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 Seven Bel’s high-performance servers. Within seconds you receive acoustic images in superior image quality. Benefit from a massively simplified workflow for measuring and analysing your sound events and share the results with your colleagues, partners or clients in the form of automatically generated reports.

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 P132 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.
