Make sure you speakers are set to a normal volume before you play the sound.
Play it and post if you can hear it or not.

It is a clip of a high frequency sound that only young people are supposed to be able to hear (below 30). I can hear it at 25. My parents could not at mid 50s. It drove my dog crazy also. Kind of stange for the dog. She is really old and her hearing is failing.
This has been floating around the news for a while, but this is the first time I heard the clip for myself.
