Acoustic Camera for Visualization of Sound Levels

The Acoustic Camera from Polytec is the optimal tool for measuring and visualizing sound level measurements. This system can be used for sound source localization on targets that are outdoors, stationary, in wind tunnels or moving, by taking real time measurements and displaying them as 3D acoustic fields.

Sound sources can be resolved just as easily on both small devices and large awkward structures, made possible by the 3D functionality and ultra-high resolution of the Acoustic Camera.

These measurements are performed very quickly. The modular and flexible architecture of the instrument allows the system to analyze the structure rapidly. Measurements are visualized and quality problems resulting in greatly reduced development effort and time.

Applications

The main applications of the Acoustic Camera are:​

Aircraft interior - characterizing aircraft cabin interior noise

Wind turbine - analyzing wind turbine noise during operation

Quality control - quality control and fault detection

Car interior - localizing strange noises coming from the car at higher speed

Sound analysis - identifying and localizing sound emissions

Noise reduction - studying potential solutions nosie reduction

Passenger interior - visualizing pass-by noise from an empty tank wagon and passenger train cabin.

Train curve squealing noise - studying the squeal of trains on curves
