A weapon of mass destruction ?
To hear what a seismic blast sounds like, to hear what the fish, whales, dolphins and seals and other underwater animals will hear, turn your speakers up to full volume
To see what a seismic gun looks like underwater.
But don’t think on land, you’re going to experience anything like the deafening, body-busting shock wave that will instantly destroy their lives. To do so, you would need loudspeakers big enough to replicate the sound of a seismic testing blast. Trouble is, there are none.
