Left: spectra of 2 walls with equal Rw + C50–5000 SNQ value (58 dB): wall “21_HW_59” N = 0.205 sone (red curve with triangles), wall “30_LW_66”, N = 0.111 sone (black curve with dots). Right: spectra of 2 walls with very similar transmitted Loudness values: wall “36_LW_69”, Rw + C50–5000 = 52 dB, N = 0.393 sone (black curve with dots), wall “17_HW_56”, Rw + C50–5000 = 55 dB, N = 0.402 sone (red curve with triangles). The mentioned Loudness values (N) are based on emitted pink noise on the sending side.
