Episode Details

A listener in Jerusalem is living next to an excavation site with rock breakers pounding at 93 dBA. His apartment's standard double-glazing drops that to 68 dBA inside — still 13 decibels over WHO guidelines. This episode unpacks why hydraulic rock breakers hit the exact frequency band where windows fail worst, how to tell if noise is airborne or structure-borne, and what glazing specs actually solve the problem. Plus: why hearing protection hits a physiological wall with low frequencies, and a brown noise hack that can bring relief tonight without touching the windows.
