Deck Acoustic Response (SounDAR) – automated concrete sounding

By inducing multiple impacts on a concrete structure on a moving platform and measuring the audible response using a microphone array, delaminations in concrete from the resulting frequency response similar to traditional hammer sounding and impact echo. For nearly a decade, BDI has been a pioneer in this technology developing both its own field data collection system and the AI-ML powered analytics model for measuring and mapping delamination on over 60 million square feet of concrete.
