Fig. 9From: Robust single- and multi-loudspeaker least-squares-based equalization for hearing devicesMagnitude responses of the occluded ear transfer function Hocc(q), the desired open ear transfer function Hdes(q) and the aided ear transfer function Haid(q) for the robust optimization for different forward path gains G0 and a N=1 and b N=2 (λ=0.1,dG=96,dH=32,β=1). The forward path gains are from bottom to top G0=0 dB, G0=10 dB, and G0=20 dBBack to article page
