WebJul 7, 2015 · In embedded or coated pipelines, the acoustic signal attenuates due to two mechanisms: damping by energy-absorbing materials of the waveguide system, and leakage of energy radiating out into the embedding material, resulting in a dramatic reduction of the test range. WebFiber attenuation can be described by the general relation dP /d z = −α P, where α is the power attenuation coefficient per unit length. If Pin is the power launched into the fiber, the power remaining after propagating a length L within the fiber Pout is Pout = Pin exp (−α L ).
