Currently the Bumblezone is pretty quiet, and it has no specific ambience. I've been doing some experiments with the AmbientSounds mod to add some background ambience to the Bumblezone, and I think it adds a lot!

I downloaded the audio from this video: https://www.youtube.com/watch?v=jpZR1xDsQiw
And then cut out a random snippet, to create this: hivenoise.zip
(It's just an OGG vorbis sound file in a Zip so GitHub would allow me to attach it.)

Then I've got it set up with AmbientSounds as follows:

    {
      "name": "bumblezone",
      "dimension-names": [ "the_bumblezone", "bumblezone" ],
      "biome-selector": {
        "always": false
      },
      "regions": [
        {
          "name": "hive",
          "volume": 0.08,
          "sounds": [
            {
              "name": "hive-ambience",
              "files": [ "ambientsounds:animals.hive-ambience" ],
	      "outside": true
            }
          ]
        },
	{
          "name": "hive-walls",
          "volume": 0.02,
          "sounds": [
            {
              "name": "hive-walls-ambience",
              "files": [ "ambientsounds:animals.hive-ambience" ],
	      "outside": false
            }
          ]
        }
      ]
    }

Basically, the sound is much more intense the more 'outside' you are, and gets quieter (but never below 0.02) if you tunnel deep into the walls.

I presume there's a way to integrate this directly into the mod proper, but I don't know enough about the Forge APIs and how other dimensions set up their background ambience to make a pull request myself. If you use to use that particular clip, you'd need to run it by the video uploader before redistributing it first, too: https://www.youtube.com/channel/UCYCmal9NJFAJqPzJXkPkcpQ

(Though there are probably lots of similar videos if permissions are problematic.)

The issue with that is the license with using other people's sounds which is why I am hesitate about that.

The main source of noise in The Bumblezone is the Brood Blocks and Bees. I would had seen about adding ambient sound to the dimension but that is not possible because of this line:

MusicTicker.MusicType is an enum that forge forgot to apply IExtendableEnums to. As of right now, this is the only ambient sound avaliable.

There may be other ways to hack in ambient sounds but will be much more trickier than the vanilla way that should've been patched by forge

1.16 version has ambiance in the way of loud bee buzzing sounds lmao. The biome json files allowed an entry for ambiance sound so I stuck the vanilla bee sounds into it.

I'll close this now as I give up trying to add ambiance to 1.15.2 and I no longer support 1.15.2.

Though if people really don't like the current loud bee buzzing sound, they could PR a sound file to me that doesn;t have any legal issues and I'll replace the vanilla bee sound with it for 1.16+. :)
