The invention provides a noise reduction method for an elevator brake and an elevator, and the noise reduction method comprises the following steps: calculating control parameters of a control power supply according to basic parameters of the brake; when the control power supply is started according to the control parameters, voltage and current output by the control power supply and noise sensor information are acquired; according to the voltage and current output by the control power supply and the information of the noise sensor, calculating the maximum starting noise value in the starting duration of the control power supply and the maximum switching-off noise value in the switching-off duration of the control power supply; and adjusting control parameters of the control power supply according to the maximum starting noise value and the maximum switching-off noise value in the switching-off duration. The maximum starting noise value and the maximum switching-off noise value are calculated on the basis of the voltage and current output by the control power supply and the information of the noise sensor, and the operation parameters of the control power supply are adjusted on the basis of the maximum starting noise value and the maximum switching-off noise value, so that the action of the brake is smoother, and the purpose of reducing noise is achieved.
