You can look on the script reference for a nice example of how something that can work for you here:Unity - Scripting API: AudioSource.PlayOneShot

Here is something else that work, but it requires you to have a collider on your objects that makes them triggers.

AudioClip impact;

void OnTriggerEnter (Collider other) 
	{
	 if(other.gameObject.tag == "Floor")
		{
			Audio.PlayOneShot(impact);
		}
			
	}

Here’s an example. Note: Untested code!

Where the sound comes from the cube, attach the AudioSource component to the cube and put in the sound effect. Add a collider to both the cube and the floor and select. Add this script to the cube.

 function OnTriggerEnter(hit : Collider) {
      if(hit.name == "floor" || hit.gameObject.tag == "floor")
           audio.Play();
 }

Where the sound comes from the floor, attach the AudioSource component to the floor and put in the sound effect. Add a collider to both the cube and the floor. Add this script to the floor.

 function OnTriggerEnter(hit : Collider) {
      if(hit.name == "cube" || hit.gameObject.tag == "cube")
           audio.Play();
 }

You may or may not need to select IsTrigger in your colliders depending on what you want to occur when the cube hits the ground.
