Sound Scanner P12

The Sound Scanner P12 has been specially developed for localizing sound events with high-frequency content in the audible as well as ultrasound domain. Its usable frequency range up to 44kHz makes it ideal for leakage testing of car cabins, containers and white goods as well as localization of gas leaks in compressed air systems and partial discharge in high voltage insulators.

The Sound Scanner P12 is equipped with 8 ultrasound microphones scanning the incident sound field on a circular disk with a diameter of 12cm at virtually more than 400 microphone positions, thus making it the acoustic camera with the highest microphone density in the market.

The high density of information on the sound field is the key to the computation of acoustic images with a superior dynamic range, thus boosting the user’s confidence when analyzing sound events at a low sound pressure level from a long distance.

Weighing in at 700 grams only, the Sound Scanner P12 is by far the lightest, most ergonomic acoustic camera on the market and supports one-handed manipulation in confined spaces.
