#$%^&*AU2008200072B220121206.pdf#####Abstract A method for determining a fault in a seismic air gun includes comparing a near field seismic signal measured during operation of the air gun to a reference near field signal and determining the existence of a fault in the air gun when a difference between the measured near field signal and the reference near field signal exceeds a selected threshold.1/3 10 1 ,-12 12 11. 24 16 16 20 20 20 20 18 21 21 21 21 19 1 18 18 14 14 14 14 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 FIG. 1
