there are general meanings which can be inferred from lyrics, but the reason why they stay and resonate with you is the personal interpretation. No alarms, no surprises, to me this carries the meaning of being at a stage of life, when there are no more surprises, disillusionment, the failure of all your dreams, the disappointment of being lied to or deceived yet again, by people, politics,the final realisation of what the world is really like and how poorly it compares to all the possiblity and hope you may felt in yr innocent youth. Its the end of the line type of feeling, the loss of innocence, the despair of maturity, no alarms no surprises could be the plea of a man so hurt and despairing, he can't stand anymore...noise. its profoundly sad, but infused with truth.
