One of the cool things about PowerPoint 2016 is that it lets you create slides that contain not only text and pictures but also sounds. You can configure the sound object to play automatically whenever you display the slide, or you can set it up so that it will play only when you click the sound object's icon.
Note that if you want the sound to play automatically and the sound is a WAV file, it's easier to add it to the slide transition than to add it as a separate object.
To insert a sound file from your hard drive onto a PowerPoint slide, follow these steps:
Move to the slide to which you want to add the sound.
Open the Insert tab on the Ribbon, click the Audio button located on the right side of the tab, and then choose Audio on My PC.
The Insert Audio dialog box appears, as shown here.
The Insert Audio dialog box.Select the audio file that you want to insert.
You may have to rummage about your hard drive to find the folder that contains your sound files.
Click the Insert button.
The audio file is inserted into the current slide, along with a toolbar of controls that let you play the sound.

You can also insert sounds from the Internet. To do so, click the Audio button on the Insert task pane tab and then choose Online Audio. Then, you can search for the sound you want to insert.
Here are a few other random thoughts on adding sounds to your slides:
To play a sound while working in Normal View, double-click the sound icon. However, to play the sound during a slide show, click only once.
Remember that you can also play audio files as a part of the slide transition.
If you change your mind and decide that you don't want any sounds, you can easily remove them. To remove a sound, click the sound's icon (which resembles a speaker) and press Delete.
