I have a human culture that gradually develops an underwater civilisation. They still require mouth and nose breathing and will be living in air bubbles, retaining traditional phones. They do spend a lot of time swimming around and I want them to be able to communicate through water as well. Modified and new underwater phones will develop over time etc.
What I'm interested in and haven't been able to find an answer to is, of our current available phones, which ones can be made, heard and understood underwater?
- let's work off the idea that there is no breathing equipment in the way of these vocalisations. Free diving.
Before I start constructing modified sounds and augmentations etc I would like to know what I can keep of our current soundbank. What do I have to throw out completely. I may ask a later question on constructing/modifying new sounds for underwater languages.
- I understand that humans hearing underwater is affected by bone conduction, skipping the first 2 ear bones. We will be able to hear much higher frequencies and from further away, although direction will be hard to discern. I'm still reading up on all of these features but just wanted to say I was aware of these various facts. For the purpose of this question, I'm just focused on using current known sounds underwater.
