I am trying to find the decibel of a user in a voice channel in discord,

if (user.decibel > 100) { user.channel.send('you husty pig, shush')}

this isn't correct code but its just an example of what I am thinking, To be honest tho I am not sure if it even exists in JavaScript, if you know a way to check decibel of an Mp3 file then I can work with it.
