Measuring the room, and taking a PhD in room acoustics or electronics or instrument building, might be something that engineers enjoy 'cause they like physics, but what does it have to do with enjoying music? All you need to know is that the room, bad recordings, can affect the sound, and that of it sounds bad ("too bright") some equalisation might be needed. Then you play with "Sound Equaliser app" for a few minutes until you are enjoying the music... job done, no PhD needed...
Again, science types might enjoy learning how music works in the brain, but that has nothing to do with enjoying music. You can spend a year learning how to cook a Michelin five star meal but the rich excutive eating it doesn't bother taking that course. The proof of the pudding is in the eating, not in the making of it. All you have to do is eat the pudding there is no need to learn how to cook it (likewise, you just need to listen to the music, no need to learn the science of how it gets neurons firing...)
Why do you need to play even one instrument? How is learning how to, say, make Minestrone soup going to help our scoffing executive appreciate a five course 5 star Michelin meal? How is learning the saxophone going to help him appreciate Beethoven's 9th? OK, becoming a great sax player is a great thing, but don't expect to it necessarily improve your general listening skills. Only listening to more music will do that, just as eating out at several restaurants will train our scoffing executive to appreciate food better than learning how to make soup. (Of course he could do both... learning to make soup is a useful skill, but as he's an excutive he might prefer listening to music as another hobby rather than making soup...) One should only bother learning an instrument, beyond forced(?) beginner lessons as a kid, if you are driven to it as a serious calling, something you must do, or if it is the least oppressive way to make a buck. Or do it if you find it to be as fun as other hobbies you might do. (Personally, there are lots of other things I'd rather do, so I'm not learning to play...)
