We present two hoods for acoustic noise damping for MRI in Radiotherapy. This is especially relevant for brain and head-and-neck patients who are scanned repetitively inside immobilization masks, which prevent wearing all the required earing protection devices. The hoods show good noise damping (average at least 10 dB attenuation) and minimal radiation dose attenuation (<1%), making them suitable also for MR-linac systems. Subjective results from a survey on 15 volunteers show that the hoods are well tolerated and do not increase significantly the feeling of claustrophobia.
