How do you quiet the the air return?
If it is the airflow that is making the noise, this is caused by undersized ducts. If you recently had your equipment replaced be sure the airflow is set properly for the size equipment you have. If it is, look into increasing the return air grille size. That may give you some improvement. If the noise is still objectionable the duct size will probably need to be increased.
