The neutron sensitivity of the C$_6$D$_6$ detector setup used at n_TOF forcapture measurements has been studied by means of detailed GEANT4 simulations.A realistic software replica of the entire n_TOF experimental hall, includingthe neutron beam line, sample, detector supports and the walls of theexperimental area has been implemented in the simulations. The simulations havebeen analyzed in the same manner as experimental data, in particular byapplying the Pulse Height Weighting Technique. The simulations have beenvalidated against a measurement of the neutron background performed with a$^\mathrm{nat}$C sample, showing an excellent agreement above 1 keV. At lowerenergies, an additional component in the measured $^\mathrm{nat}$C yield hasbeen discovered, which prevents the use of $^\mathrm{nat}$C data for neutronbackground estimates at neutron energies below a few hundred eV. The origin andtime structure of the neutron background have been derived from thesimulations. Examples of the neutron background for two different samples aredemonstrating the important role of accurate simulations of the neutronbackground in capture cross section measurements.
