Room silencing, vibration reduction, vibration and noise measurements
Room silencing, vibration reduction, vibration and noise measurements
The Sound Scanner P132 has been specially developed for applications in the fields of mechanical 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 visualized.
Sound Scanner is a new type of acoustic camera created by the Austrian company Seven Bel. The innovative system consists of the following elements:
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.
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.
