Devices, systems, and methods for noise reduction

A device for noise reduction disposed on a head coil assembly, comprising:

• a noise receiving component configured to receive acoustic noise information of a scanning environment where a medical device is located;
• a first housing;
• a second housing, the second housing and the first housing forming an accommodation chamber;
• a noise reduction component located on the first housing and/or the second housing;
• a support component configured to support the noise reduction component, wherein the support component includes a support frame and a vibration isolation structure, the vibration isolation structure is located in the support frame or located between the support frame and the noise reduction component;
• and
• a processing component configured to control the noise reduction component to generate sound information matching the acoustic noise information received by the noise receiving component.

A device for noise reduction, comprising:

• a first noise receiving component located on an inner side wall of a chamber;
• a first noise reduction component located on an outer surface of a housing;
• a second noise receiving component located on an inner surface of the housing;
• a second noise reduction component located on the inner surface of the housing;
• a support component configured to support a noise reduction component, wherein the noise reduction component includes the first noise receiving component, the first noise reduction component, the second noise receiving component and the second noise reduction component, the support component includes a support frame and a vibration isolation structure, the vibration isolation structure is located in the support frame or located between the support frame and the noise reduction component;
• and
• a processing component configured to control the first noise reduction component to generate first sound information matching first acoustic noise information received by the first noise receiving component and/or control the second noise reduction component to generate second sound information matching second acoustic noise information received by the second noise receiving component, wherein the first acoustic noise information and the second acoustic noise information are from a scanning environment where a medical device is located.
