I honestly don't know (there may be something on their website). It is loud enough for a bedroom especially the goat alarm at full volume. It has built in alarm sounds but music is either from USB or bluetooth connection.
It certainly does. There are nice ones - tree frogs, crickets, various running water and so on, and bizarre sounds such as traffic noise and a steam train. 16 sounds in all, but you can add your own sounds using a USB stick too.
