ASSR measurement was performed with the synchronous stimulation pattern in a sound and electromagnetic shielding room, including 8 points for both ears of the same stimulation intensity and the carrier frequency tones of 0.5, 1, 2 and 4 kHz respectively.

• 在声电磁屏蔽室内进行多频稳态诱发电位检查；采用双耳同一刺激强度、相同4个载频音0.；5；1；2和4kHz共8个点同步刺激模式。
