Controlling sounds on Mac is really easy. The sound icon shows on the menu bar somewhere to the extreme right. This sound icon can be shown and hidden as per your choice. To increase and decrease the volume all you have to do is just click on the sound icon on the menu bar and then click on this sound icon and you will get the seek bar that allows you to adjust the volume.
There are some further sound controls and to play with it all you need to do is, open System Preferences and click on Sound.
