Figure 10 :Comparison of subjective responses to LFN between subjects from the experiments I and II linear regression models with median annoyance rating (dependent variable) versus low frequency A-weighted SPL LLFAeq,T (a), and C-weighted SPL LCeq,T (b). Solid lines and symbols (circles and squares) represent regression models and observed data, respectively (dashed lines 95% confidence intervals). Linear regression equations with probability P and adjusted R2 values are included in the graph (coefficients in the equations are specified with their standard errors)
