Soundproofing Companies: Investment Potential or Just Hype?

I’ve been looking into soundproofing lately, partly for my home studio setup and partly out of curiosity about the industry’s growth. With more people working remotely and noise complaints on the rise, it seems like there could be some solid opportunities here. Has anyone dug into whether soundproofing companies are actually worth investing in, or is the buzz mostly just that noise? I’d love to hear your thoughts or if you’ve come across any standout players in the field.
