Elena, normally ears don't become deaf, people do. That's really wordy :(

Uly, I know👂👂, but I found it on the internet:
https://books.google.com/ngrams/graph?content=ears+become+deaf&year_start=1800&year_end=2000&corpus=15&smoothing=3&share=&direct_url=t1%3B%2Cears become deaf%3B%2Cc0

EARS BECOME DEAF could include cases like “children who listen to loud music and suffer damage to their EARS BECOME DEAF by the time they’re adults” so it’s not a valid index. As I said, it’s not impossible, but it sounds very awkward.

There are other examples with this exact meaning:
https://www.google.ru/search?q=%22ears+became+deaf%22&tbm=bks&lr=lang_en&gws_rd=cr&dcr=0&ei=Nb2VWsXVAs-OmgXxvrPQDQ
But, of course, if you say it's awkward, I'll delete it )

It wasn’t just the “ears become deaf“ - I don’t remember exactly what it said, but there were lots of unnecessary words.
