We present an exploratory investigation into using simulation-based inference techniques, specifically Flow-Matching Posterior Estimation, to construct a posterior density estimator trained using real gravitational-wave detector noise. Our prototype estimator is trained on a nine-dimensional space, and for training efficiency outputs posterior probability distributions for the binary black holes chirp mass and mass ratio. We use this prototype estimator to investigate possible effects on parameter estimation for intermediate-mass binary black holes and show statistically significant reduction in measurement bias. Although the results show potential for improved measurements, they also highlight the need for further work.
