听力学的发展已从耳聋的定性走向定位,由周边深入听觉中枢。听觉中枢包括脑干(高位与低位),小脑和大脑。大脑应分听觉接受区(听区)与非接受区(非听区)。中枢测听开始时,以为语言的客观性与正确性不及纯音测试。经过多年探索,各种纯音测听均无成效。Bocca(1954)采用滤波语言测试才获成效,从此发展出各种崎岖语 The development of audiology has been from the qualitative deafness orientation, by the surrounding depth auditory center. The auditory center includes the brainstem (high and low), cerebellum and brain. The brain should be divided into auditory acceptance zone (auditory zone) and non-accepted zone (non-auditory zone).
