Azimuth tuning for 3 frequency bands for matched neurons in the anechoic and moderately reverberant (A) and the anechoic and highly reverberant (B) environments. To increase the population sample the vector strengths at the 2 farthest distances (80 and 160 cm) were combined. If a neuron was tested at both distances, then only the 160 cm response was retained. The neurons were assigned to 1 of 3 carrier frequency bands (low: 0.3–2.0 kHz, middle: 2.1–6.2 kHz, and high: 6.3–16.0 kHz) based on their best frequency. Sample sizes: low band: anechoic (n = 42) and moderate reverberation (n = 36), anechoic (n = 22) and high reverberation (n = 8); middle band: anechoic (n = 31) and moderate reverberation (n = 23), anechoic (n = 25) and high reverberation (n = 13); high band: anechoic (n = 25) and moderate reverberation (n = 18), anechoic (n = 21) and high reverberation (n = 16).
