Urban sprawl and deforestation destroy natural carbon absorption reservoirs while removing natural sound buffers... Conversely, certain climate mitigation strategies such as creating green spaces in concrete jungles offer opportunities to muffle noise.

Yeah, we need to up our game on making better places and it needs to be a holistic approach.

Re the stuff about heart health and noise sensitivity:

Magnesium deficiency can cause noise sensitivity. Magnesium is also critical to heart function, specifically the ability to keep the beat.

Furthermore, noise causes physical vibrations much like the beat of the heart, which is something you can listen for in a patient.

Armies historically marched to the beat of a drum because you can feel the vibrations even if you can't really hear it over the din of war.

You can put a baby to sleep by calming yourself and then holding them in your arms. The beat of your heart will not only set the pace for theirs, it will lend their heart some of your energy, making it easier for them and helping them to relax.

Given the constructive ways vibrations can impact us, it should be no surprise that vibrations from noise can also negatively impact the heart.
