The world is filled with noiseof various kinds; ranging for industrial and mechanical to even ideological noise which rubs on of the quietude that enhance the unity of the body and spirit.
The worst as you noted is what i may call in my terms financial or economic noise, which often times distract those who have been able to grasp the reality of serenity, coated inform of bumper offers, contracts and even trade which takesone away from a greater value which serenity and naturalness offers .
Its amazing that you have found a sense of this quietude and serenity which futher enables you to see the need to see those you can help with the friut of your rapport with nature. Ride on, you are on the right track. Serenity is so to say freedom to see things as they are.
