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.
数据处理就像设备安装一样简单。每次测试以后，APP将数据传输至高性能服务器，只需数秒您即可获得高分辨率的声场图像。得益于简化的测试流程、简单的测试和分析以及自动生成测试报告，您将非常方便地与同事、合作伙伴或客户共享测试结果。
With the patented innovation of a moving sensor, Sound Scanners are able to simulate up to 480 virtual 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 a 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.
我们拥有移动传感器测试专利的专利，Seven Bel声场扫描仪只需要5个物理麦克风即可分析相当于一周内最多480个虚拟麦克风的数据，而传统声学相机往往只得到约100个麦克风的数据。这一特点极大地提高了测试的质量，P50拥有便携性、易操作性、便于运输，并可得到高品质的分析结果。该系统无需要电脑和适配器，亦无需数采，简单易用。

SOUND SCANNER sevenbel P50
The Sound Scanner P50 is an acoustic camera specially developed for visualizing medium- to high-frequency sound events. Due to its size with a measurement diameter of 50 cm, the Sound Scanner P50 can easily be used in confined spaces. The increased rotational speed also allows exact measurements on moving objects.
P50声场扫描仪是一款专为中高频声场成像而设计的声学照相机。得益于其紧凑的50CM长尺寸，P50声场扫描仪可以轻易地应用于有限空间内。它拥有较高的旋转速度，因此可对移动物体进行精准定位。
Our measurement devices include three subsystems: the sensor, a smartphone with preinstalled software, and the Seven Bel cloud-infrastructure. 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.
该测试系统由三部分组成：传感器，预装软件的手机和Seven Bel云计算。传感器由高质量的碳，陶瓷和铝合金制成，轻质而紧凑耐用，简单易操作，可以很方便地携带到任意场合。
