Velocity Measurement Equipment

Campbell Associates can provide the full exciting range of particle velocity sensors for sound and vibration measurements. Sensors of a very high specification for accurate and quick measurements - Directional characteristics make sensors ideal for source localization - Near field measurements - Sound intensity measurements - In-situ sound absorption measurements.

Pinpoint Acoustic Leaks

pinpointing the acoustic leakage of an acoustic enclosure or machinery used to attenuate a loud noise source becomes difficult. PU probe based sound intensity measurements capturing both sound pressure and acoustic particle velocity are not affected by background noise.

Scan and Listen

Better Than Human

Human ears only hear sound pressure, with Scan & Listen particle velocity is now also made audible! Human ears are like traditional microphones sensitive to scalar value / omnidirectional sound pressure. The Microflown however is sensitive for vector value / directional acoustic particle velocity.

Absorption Setup

In-situ method

A complete solution to measure your material properties with the In-situ absorption setup. With a small, handheld impedance gun the acoustic absorption, reflection or impedance can be measured in just a few minutes, broad banded, under normal and oblique angles
