Noise and Impact Hammers American Piledriving

What is noise? Where does it come from? Noise is a vibration. The kind of vibrations we are discussing are those created by impact pile driving. As we will see, these noise vibrations may not be coming from the hammer, but from the pile driving system as a whole. APE D-46-32 at full stroke on test stand in California undergoing sound tests.
