Sound Scanner P132

Seven Bel's Sound Scanner P132

The Sound Scanner P132 is a portable acoustic camera engineered for precise low-frequency noise measurements in mechanical engineering, building acoustics, and environmental noise. Its 1.32-meter sensor array enables detailed sound localization and reliably detects sound sources starting at 250 Hz, making it ideal for identifying noise in complex environments.

Its large diameter and 400 virtual microphone positions provide the spatial resolution needed to pinpoint even subtle acoustic anomalies and closely spaced sound sources.

With its modular and flexible design, the Sound Scanner system adapts seamlessly to various industrial and environmental applications. Whether you’re diagnosing machinery noise, improving building sound insulation, or conducting environmental noise assessments, the P132 delivers fast, high-resolution acoustic images to support your analysis.

Trusted by professionals across industries, the Sound Scanner P132 is our most popular acoustic camera, combining portability with low-frequency precision.
