Look at the README file included with the drivers. It includes instructions for installation and possibly some caveats you might want to be aware of. That's good general advice, though.
Anything else depends on your sound card. If you have a standard Sound Blaster compatible card and zero requirements, Windows 3.1 contains Sound Blaster and AdLib drivers (Control Panel -> Drivers -> Add). The Sound Blaster drivers complain on newer cards, but work fine. If you have a PnP sound card, take a look at UNISOUND; it is a modern tool, run once at boot, to configure the card. It's not memory-resident. At this point, many cards become Sound Blaster compatible and may work with the Windows standard drivers.
