Just the answer for the required sound level when frequency is 5000 and frequency of auditory nerve fiberThe two blanks

Based on Figure 1, let's decide the response area and the tuning curve of the Auditory Nerve fiber. 60 55 + 2500 Hz 50 - 3000 Hz 45 3500 Hz 40 Spike Rate (Spikes/Sec) 10 25 30 35 40 45 50 55 60 Level (dB SPL) The response area at the sound level of 50 dB SPL: Frequency (Hz) 2500 3000 3500 Spike Rate (spikes/sec) 50 55 40 The tuning curve for a spike rate of 50 spikes/sec Frequency (Hz) 2500 3000 3500 Required sound level 50 45 (dB SPL) Based on the response area and the tuning curve, what is the characteristic frequency of the Auditory Nerve fiber? Hz
