Figure 5: Mean level and standard deviation of measurements taken using the reference acoustic manikin (MAN.SP) with each headset and audio signals (n = 12 participants) for both fits. Measured in-ear levels and diffuse-field related levels obtained with the third-octave correction factors specifi ed in ISO 11904-2 are shown
