Non-contact surface wave scanning of pavements using a rolling microphone array

Rydén, Nils LU ; Lowe, Michael J. S. and Cawley, Peter (2008) 34th Annual Review of Progress in Quantitative Nondestructive Evaluation 975. p.1328-1332
Abstract
We present experiments with a rolling multichannel microphone array where measurements can be taken continuously while moving. Leaky air-coupled surface waves are measured with ordinary non-directional audio microphones. Results show that microphones can be successfully used to produce a realistic phase velocity spectrum even while moving along the surface. The paper presents some theoretical background along with initial experimental results using the moving microphone array.
