Shouko was born deaf due to an illness that Yaeko contracted during pregnancy. As for the blood on the sweater thing, that was an injury she received when Ishida ripped a hearing aid out of her ear. It cut her open, he mentions the scar that the injury left later on. Miyako's talk with Yaeko was only to pay back the debt that Ishida had built from destroying Shouko's hearing aids, and to apologize for the debt and for Ishida injuring Shouko. None of which caused Shouko to become deaf.
