The time averaged frequency is also known as the weighted mean frequency and is a seismic attribute. This frequency attribute is less influenced by short wavelength effects. Longer wavelength factors, such as absorption due to thick beds or massive sand bodies, will change the propagating wavelet characteristics that can be observed on the weighted mean frequency attribute. It is a physical attribute, indicating longer wavelength variations.[1]

${\displaystyle {\bar {\omega }}(t)={\frac {\sum \limits _{T}^{}[E(t).Freq(t)]}{\sum \limits _{T}^{}[E(t)]}}}$
