Sound Scanner P254
The Sound Scanner P254 was specially developed for environmental noise measurements and applications with particularly low-frequency sound events. With a measurement diameter of 2.54m, it is the world’s largest portable acoustic camera that can accurately localize frequencies starting from 125 Hz.
The Sound Scanner P254 extends the portfolio of Sound Scanners for special applications in the low-frequency range. The modularity of the Sound Scanner system allows you to achieve optimum measurement results for your applications of interest.
Leverage the opportunity of now being able to localize particularly low-frequency sound events and benefit from a fast setup time. The Sound Scanner quickly delivers results with high image quality, from which you can effectively derive targeted technical solutions.
