Cold Brook Sand and Gravel is in Boscawen and occasionally does blasting as a step in making crushed granite. I knew about it when I lived in the south end of town, but never felt or heard the blasting. Raspberry Shakes can feel it, both nearby across the river in Canterbury and out here in Sutton. High frequencies in rock and in air attenuate, So Sutton feels mostly the low frequencies.
