Episode Details

Construction noise isn't just annoying — it's a measurable public health problem. But most cities still enforce noise rules with complaint-driven, reactive systems that barely work. In this episode, we dig into the emerging world of acoustic sensor networks, frequency classification, and what it actually takes to tie noise ordinances to real-time sound level data. From Barcelona's smart city sensors to the physics of sound in dense urban canyons, we explore why treating each construction site as its own monitoring project might be the only way to make enforcement meaningful — and whether any city has actually pulled it off.
