Patent ID: 7466625

Claim:
A method, comprising: recording a first set of data using a first type of sensor; recording a second set of data using a second type of sensor, the first and second sets of data being contemporaneously acquired by co-located sensors; estimating an inline noise component in the first set of data from the second set of data using n x (t,x r )=d x (t,x r )−1/ρ∂ x P(t,x r ), where d x (t,x r ) represents recording of a particle sensor in the inline direction, a x (t,x r )=1/ρ∂ x P(t,x r ), P(t,x r )represents the inline gradient of acoustic sensor recordings and a x (t,x r ) represents the inline component of particle acceleration and ρ represents the density of the medium in which the particle sensor is located; and correcting the first set of data using the estimated inline noise component.
