The present invention belongs to the technical field of medical instruments, and specifically relates to a traditional Chinese medicine pulse manifestation acquisition apparatus. The apparatus comprises a sensor array, a multipath signal conditioning circuit, a multipath synchronous A/D circuit and a single chip microcomputer; the sensor array comprises pulse sensors and noise sensors, and the noise sensors are used for acquiring vibration noise data introduced by a body; the multipath signal conditioning circuit is used for filtering and amplifying signals acquired by the sensors; the multipath synchronous A/D circuit is used for synchronously acquiring the signals processed by the multipath signal conditioning circuit in real time and converting the signals into digital signals; and the single chip microcomputer is used for sending the converted digital signals into an intelligent terminal. The present invention also provides a noise reduction system and a noise reduction method. The pulse sensor data are corrected by utilization of noise sensor data, interference of vibration noise on a traditional Chinese medicine pulse manifestation instrument can be effectively reduced, and therefore repeatability and accuracy of pulse manifestation instrument diagnosis can be improved.
