1. A method of filtering seismic data, the method comprising:
receiving seismic data from one or more seismic sensors;
storing the seismic data in a non-transitory memory component;
comparing amplitude coefficients of elements of a matrix storing the seismic data in a time-frequency domain against an amplitude threshold, and comparing frequencies of the elements of the matrix against a maximum expected frequency of noise;
for each amplitude coefficient having less than the amplitude threshold and an associated frequency less than the maximum expected frequency of noise, scaling the amplitude coefficient to reduce its value;
performing an inverse time-frequency transformation on the matrix to generate a noise model in a time domain;
subtracting the noise model from the seismic data in the time domain to generate filtered seismic data, and
displaying, on an electronic display, a graphical representation of the filtered seismic data.
