Figure 2 :Examples of noise samples used in experiment I - frequency spectra of noise samples played at nominal SPL of 55 dBA. Spectra A, B and C are LFNs, while spectrum D is a broadband noise without dominant content of low frequencies. (LAeq,T is the equivalent-continuous A-weighted SPL, LC - LA is the difference between equivalent-continuous C- and A-weighted SPLs)
