What is noise-induced hearing loss?
Your child’s inner ears may be damaged if he or she is around extremely loud noises or around loud noises for long periods of time. This is called noise-induced hearing loss.
One way of describing noise is by decibels.

They don't use common names because the want other scientist to know what their talking about.∞
It is very condensed compared to gas. The atoms are more compact in water than in gas. Solids are even more compact and are extremely condense compared to gas. Hope this helps!
False, I'd say. Mammals usually adapt based on environment. Now, I know predators are "apart" of the environment, but I don't think that'd be it. I'd bet more money on saying mammals evolve based on environment adaptation. Sorry if I didn't answer your question or if I didn't get my point across well.
