Figure 9.

The benefit of listening through the beamforming microphone array (BEAM or BEAMAR) compared with natural binaural listening (through KEMAR manikin) plotted as a function of the thresholds for the natural binaural listening condition. Positive values (above the dotted horizontal line) indicate that the thresholds were better (lower) for BEAM or BEAMAR than for KEMAR conditions. The data points are for individual subjects for speech maskers (circles and triangles) and for noise maskers (squares). NH = normal hearing; SNHL = sensorineural hearing loss; T/M = target-to-masker ratios.
