Testing of intensity coding occurs as monotone stimulation and recording
Testing of intensity coding occurs as monotone stimulation and recording
- Hearing threshold testing
- Behavioral Audiology- Frequency and intensity threshold
- Auditory Brainstem Response (ABR)
- Nerve unit recording (Experimental animals)
- Loudness of sound
- Faster firing rates in nerves
- Recruitment of more afferent fibers from 20 to 40 on each inner row receptor cell.
- Thresholds of afferent fiber may vary to produce loudness range.
- Too loud- middle ear reflex 100 dB + Co-contraction of tensor tympani and stapedius muscle blocks injury to middle and inner ear structure.
