The trees are absorbing sound for you. That is what they do. The more appreciation you give the trees around you, the more they will be able to help. Houseplants can absorb the sound from inside and even planting more trees or foliage outside help. It is the intention that will do it.
Your personal frequency is very high so the negative noises and interactions are there to balance yours. The cars in a sense, are driving by to mess with you. Not in an intentional way but a random way. You may already get a sense of this. It is true. The more you can accept that the world wants to vibrate with the resonance of you, the more you will stop feeling like a victim of the noise.
That is important because feeling like a victim closes down your energy and then you are not as comfortable in you bliss. So if you can counter the noises with gratitude that others are desperately seeking what you have, you can keep your energy open. Because gratitude opens up the chakras. In that way, you will be gifting all around you, the ability to match your resonance. That is very healing for the planet and for humanity.
