I use noise before sleeping due to some mild tinnitus. I tried the Alexa/Spotify approach for a while, but didn't like the gaps between the tracks or anything else that would make me take notice of the background sound. I ended up repurposing an old Android tablet hooked up to a cheap USB powered speaker bar through the headphone jack of the tablet. It runs the White Noise app, and I go for sea/waves types of sound. I keep the tablet offline in airplane mode with a very short display-off setting. The sound can loop continuously, or you can set it to switch off after a certain time. It's been really great every night for the last few years. I did research some sort of sleep machine box on Amazon, but it's surprisingly difficult to find something that doesn't want to shine bright status LEDs into your darkened bedroom, or other annoying things.
