The invention discloses a low-noise concrete vibrating bar, which comprises a bar body and a motor arranged in the bar body, wherein two ends of a rotating shaft of the motor are fixedly arranged in the bar body through a bearing, the rotating shaft arranged at the front end of the motor is connected with an eccentric block, a circuit of the motor is connected with a frequency converter controlled through a sound control sensor, a fixing bearing is also arranged on the rotating shaft arranged between the eccentric block and the motor, the frequency converter is arranged in a casing, and the motor is a three-phase variable frequency motor. The low-noise concrete vibrating bar has the advantages that no knock is generated in the vibration mode, the noise is eliminated, and the environment is favorably protected; the noise decibel is detected through the sensor for controlling the rotating speed of a centrifugal part of the vibrating bar, and the immediate response noise reduction is realized; no knock is generated, so the damage to the inner wall of a bar body of the vibrating bar is avoided, the service life of the vibrating bar is long, and in addition, the vibration effect is good.
