What does 听得见摸得着了 mean? In the following sentence:


  最初的体验便是心跳加速，仿佛有一只小锤不停地捶打你的喉咙。不吃饭时，这种感觉时轻悠悠的，吃了饭，这个小锤便从喉咙升到头顶，产生轻微的震动，震得头有些疼。不知为什么，我觉得这是一种生命的体验。在这样的反应中，生命好像听得见摸得着了。


I think the bold part uses a degree particle, and there are two components concatenated without any conjugation.

So the sentence structure is


  (听得见 + 摸得着) 了


However, I then don't understand what it means. It looks like the sentence means "listening to it feels like seeing it, and... " but then "touching on it feels like touching on it..." which does not make sense.

Also I don't understand the last 了. Is it for meaning the change of a status, right?

So is my grammatical understanding correct? Then what does the bold part mean?



EDIT

To clarify my point, I understand the verbs here are result complements. I also understand what 听得见 means here (the action 听 results in 见, which is  "listening to it results in seeing"). But 摸得着 then does not make sense, as 摸 and 着 seem to mean the same, and so it sounds like the action of touching results in touching...

At least if it is 摸得懂, I understand it. (as the verb before and after the complement means different)...
生命好像听得见摸得着了


The sentence can be paraphrased as 生命好像可以被听得见、摸得着了. It can be translated to it seems that now life might be heard and touched. The reason why 了 is there is that originally we assume that life is not something that can be heard and touched, but in author's case he feels like he could be able to do so. 了 here denotes now the situation changed(unable -> able).
