# Sound (Interaction)

The `interaction_sound` property can be used to customize which sound the machine will make when the player place/break/hit/step on/fell on it.

There are 2 ways of using this property : 

### Copying another block

Simply specify a block id to the property and the machine will copy all sounds it make.

You can also use the `namespace:block[property1=value1,property2=value2]` syntax here as some blocks may have different sounds depending on their state.

#### Example

This machine will make the same sound than a netherite block.

```json
"appearance": {
    "interaction_sound": "minecraft:netherite_block"
}
```

### Tweaking sounds individually

The 5 interaction sounds `break`, `place`, `hit`, `fall` and `step` can be defined independently.

You can define them using either : 

* A block : `namespace:block_id`
* A blockstate : `namespace:block_id[property=value, property2=value2]`
* A sound : `namespace:sound_id`

{% hint style="info" %}
Look at the suggestions given by the `/playsound` command in game to see all available sound ids. You can also add your own sounds.
{% endhint %}

You can also specify a `volume` and `pitch` that will be used when playing the sound.

Default value for both `volume` and `pitch` is 1.0

#### Example

This machine will have the sound of the stone when placed, the grass when broken, and the npc hurt sound when step on.

```json
"appearance": {
    "interaction_sound": {
      "volume": 1.0,
      "pitch": 1.0,
      "place": "minecraft:stone",
      "break": "minecraft:grass",
      "step": "minecraft:entity.villager.hurt"
    }
}
```
