acoustic blanking is a technique used in geophysical exploration to remove unwanted acoustic reflections or echoes that interfere with the detection of subsurface structures or formations. This technique involves identifying and removing sections of the acoustic data that contain noise or interference, which can be caused by various sources such as surface equipment, wind, or other environmental factors. Acoustic blanking is commonly used in seismic data processing to improve the quality and accuracy of subsurface imaging and interpretation. It can also help to reduce the costs and time required for exploration and development activities by improving the efficiency of data acquisition and interpretation.
