Reduce volume/harshness of some sound effects

[FuzzyLeo]

Describe the feature request

Most of the sounds are fine, but a few could do with some tweaks imo, particularly i think apart from the neon hum the hum sound effects are far too loud for what should really just be background noise that you can tune out, making them more irritating than atmospheric, especially when it comes to the more repetitive/harsh classic sound effects

another sound that i think could be tweaked is the scanner beeping, it hurts my ears a bit and i think could either bit pitched down or changed to something else entirely to something less harsh sounding

it should be noted that changing the volume perameter doesn't actually quiet the sound, only the distance it can be heard from, so making it quieter should probably be done in the sound file itself

this is low priority and shouldn't be seen as a big issue, its just something i thought could be tweaked when convenient

Describe alternatives you've considered

its not possible to control these sound effects separately in the volume sliders or in the config, and even if it were possible to change them through the separate sliders these sounds should preferably match vanilla sounds in volume
