1. A combine comprising:
a feeder housing for receiving harvested crop;
a separating system for threshing the harvested crop to separate grain from residue;
a grain sample sensor for detecting frequencies of impacts of the separated grain on the grain sample sensor;
a grain loss sensor for detecting frequencies of impacts of residue and lost grain on the grain loss sensor; and
a controller that controls the combine, the controller configured to:
receive, from the grain sample sensor, the frequencies of the impacts of the separated grain,
receive, from the grain loss sensor, the frequencies of the impacts of the residue and the lost grain,
set a detection frequency band based on the frequencies of the impacts of the separated grain,
filter the frequencies of the impacts of the residue and the lost grain based on the detection frequency band,
determine, from the filtered frequencies, grain loss information, and
indicate the grain loss information to an operator of the combine, or control the combine based on the grain loss information.
