Abstract
Air wave noise caused by a vibrating baseplate on a seismic vibrator is reduced or eliminated through passive absorption of sound. In passive absorption, reduction of air wave noise is achieved by building a rigid, light-weight enclosure for the baseplate which remains isolated from the induced ground vibrations and nonresonant.
