I feel like the world needs more sound engineers. There's a constant humming of the machines and we all suffer for it. We also need more vigilance about preventing noise pollution. The beep, beep, beep may make a company feel like it is doing something for safety, but there is no counterforce that they have to answer to about what they are doing to everyone else not involved. (I know there is a better sound to replace beep beep beep but it hasn't made it to my neighborhood yet)

We would need to figure out a quantifiable metric for annoyance level. Municipal sound ordinances do tend to correctly utilize SPL(A) and SPL(C), with A-weighting being relevant for safety against ear injury (low frequencies have less influence) and C-weighting being relevant for annoyance level (low frequencies have more influence), but this isn't nearly enough. For example, ordinances carve out additional tolerance for burstiness, which makes sense for rare events like jackhammering but not for common events like routine plant operations. Sound with lots of harmonic content (think distortion) is more annoying than without. High frequencies can be worse if they reach you, but they're less likely to reach you (approaching a need for line-of-sight). It's complicated.

Here's a free idea for someone to run with: just as Zillow has a neighborhood "walkability" score prospective buyers might look at, there could be various pollution scores, including sound and light, sourced from some kind of Flock-like (ew) network of capture devices. Some folks are into mounting things like personal weather stations on their property, so maybe a new generation of devices capturing this type of data (with local signature-based identification of sources, and triangulation when the same thing is heard in multiple places, etc.) wouldn't be too far-fetched.

All the sound engineers in the world can't fix "don't care" and "want to".

A modern US city has the combined problems of cheap construction of residential buildings, with insufficient unit-to-unit and exterior noise isolation (builders "don't care"), and near-zero enforcement of vehicle noise laws (police and muffler shops "don't care", drivers "want to" be loud).

Contrast this with, say, Germany or Switzerland, where concrete construction is the norm, noise laws are often strictly enforced, and a modified car would get pulled over quickly.

They could start with building codes. State of the art, beautiful new designs where you can hear every word of the meeting next door.

The constant humming that causes the overwhelming population-weighted noise pollution comes from cars and airplanes, due to the fact that in America it is currently not legal to build an apartment except within 100ft of a freeway or at the ends of airports.
