Apart from recording a new sound from a microphone, you could read an existing sound file from your disk.
With Read from file... from the Open menu, Praat will be able to read most standard types of sound files, e.g. WAV files. They will appear as Sound objects in the Object window. For instance, if you open the file hello.wav, an object called "Sound hello" will appear in the list.
If you do not have a sound file on your disk, you can download a WAV file (or so) from the Internet, then read that file into Praat with Read from file....
