Objective BC OE. According to figure 1.1, the objective BC corresponds to the path A2a. In Fig. 1.10 four objec- tive BC OEs from the literature are presented with our subjective VABC OE. As mentioned in section 1.6.2, three of the objective BC OE measurements presented here (one from Xxxxxxxxx et al. (2007) and two from Xxxxxxxx and Xxxxxxxxx (2007)) are issued from the same studies and use the same earplugs as three of the subjective BC OE measurements presented in Fig. 1.9. The fourth one (Lundh (1986), Xxxxxx (1986)) is included because in their study an objective voice OE has also been quantified in the same conditions (it will be presented in section 1.6.5).
