Figure 6. — Binaural cue distortions evident in noise are also evident in speech signals. (a) Right- and left-ear signals for the CVC word “purse” presented from the speaker at 0° azimuth as measured through 2, 4, and 6 kHz filters. (b) Comparison of HA signal energy in the 4 kHz frequency band without (blue) and with (green) frequency compression enabled. Frequency compression reduces signal amplitude by 9 dB but also introduces notable asymmetries in the left and right signal envelopes (black arrows). (c) Time-varying ITD (upper row) and ILD (middle row) within the 4-kHz frequency band for the word purse presented from the speaker at �imuth across conditions. Note. HA = hearing aid; ILDs = interaural level differences; ITD = interaural time difference.
