Auditory neurons have frequency {characteristic frequency} (CF) at which they are most sensitive. The characteristic frequency is at the maximum of the frequency-intensity spectrum (threshold tuning curve). For CF = 500 Hz at 0 dB, 1000 Hz is at 80 dB, and 200 Hz is at 50 dB. For CF = 1100 Hz at 5 dB, 1500 Hz is at 80 dB, and 500 Hz is at 50 dB. For CF = 2000 Hz at 5 dB, 3500 Hz is at 80 dB, and 500 Hz is at 80 dB. For CF = 3000 Hz at 5 dB, 3500 Hz is at 80 dB, 700 Hz to 2000 Hz is at 50 dB, and 500 Hz is at 80 dB. For CF = 8000 Hz at 5 dB, 9000 Hz is at 80 dB, 1000 Hz to 3000 Hz is at 60 dB, and 500 Hz is at 80 dB. For CF = 10000 Hz at 5 dB, 10500 Hz is at 80 dB, 5000 Hz is at 80 dB, 1000 Hz to 2000 Hz is at 60 dB, and 500 Hz is at 80 dB.
