The membrane is probably there because if it's not you'll be venting boosted intake gas to atmosphere. You could channel boosted air to the cabin but this is a boost leak. The membrane transfers the vibration from one chamber to the other so that sound/vibration can be channelled to the cabin without a loss of boost. Clever solution, but I'm with you on keeping engine noise in the bay.
Great video! I had no idea the inside of the symposer looked so precarious

Lovely cat
It’s not that nice when it tries to wake you up at 3am for no reason 😂
