Age 15Explain it to a 15-year-oldConnect it to the formula
A simple exponential attenuation coefficient is the natural logarithm of initial-to-final amplitude ratio divided by distance. This page isolates propagation distance and verifies it in the original relationship. The rule is b=ln(a)/c. Its input values are log-amplitude loss per distance, initial-to-final amplitude ratio, and the main result is propagation distance. For example: initial-to-final amplitude ratio=4 and propagation distance=120 produce log-amplitude loss per distance=0.011552453009332421.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated seismic log-amplitude attenuation coefficient: solve propagation distance relation over the valid real-number domain stated below. The implemented relation is b=ln(a)/c, evaluated from log-amplitude loss per distance, initial-to-final amplitude ratio to produce propagation distance. A simple exponential attenuation coefficient is the natural logarithm of initial-to-final amplitude ratio divided by distance. This page isolates propagation distance and verifies it in the original relationship. Geometric spreading, site response, scattering, frequency, instrument response, and phase changes must be separated from intrinsic attenuation.
Inputs and valid domain
- log-amplitude loss per distance must be a finite real number.
- initial-to-final amplitude ratio must be a finite real number.
Important boundary: Geometric spreading, site response, scattering, frequency, instrument response, and phase changes must be separated from intrinsic attenuation.
The formula

How the calculator works through it
It substitutes log-amplitude loss per distance, initial-to-final amplitude ratio into the formula and exposes every numerical step above. The main output is propagation distance, accompanied by Reconstructed log-amplitude loss per distance.
Read the result correctly
The propagation distance is the direct answer to “rearrange the seismic log-amplitude attenuation coefficient relationship and solve for propagation distance.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
initial-to-final amplitude ratio=4 and propagation distance=120 produce log-amplitude loss per distance=0.011552453009332421.
Where this model stops being reliable
Geometric spreading, site response, scattering, frequency, instrument response, and phase changes must be separated from intrinsic attenuation.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
