I don't understand this passage


> クリニックでは、症状を訴える患者が「聴力検査」で異常がなければ、 **50音のどれかをランダムで発音し聞き取れるかどうかをチェックする**
> 「スピーチ検査」に移ります。
>
> **そこで一定以上の正答率であれば**
> 、聴力に問題がないため聴覚情報処理障害の疑いが高まり、場合によっては脳の画像診断なども行って判断していくそうです。([source](https://www3.nhk.or.jp/news/html/20180926/k10011645091000.html?utm_int=news_contents_netnewsup_004))

1°)50音のどれかをランダムで発音し聞き取れるかどうかをチェックする=> "To check if the patient understands
sounds(50 different sounds possible) said randomly" It doesn't make sense
since if they are said randomly they shouldn't be intelligible...?(and I don't
think it's just recognizing the sounds since it's a test done if there are no
problems with the hearing(「聴力検査」で異常がなければ)).

2°) I don't understand why giving correct answers is bad and shows that we
have 聴覚情報処理障害?




For me, 50音 refers to アイウエオ、さしすせそ、etc., which are played randomly, and the
patient is asked to identify what they hear, so it’s a step further after the
hearing check. If they give correct answers, it means although they can
identify the basic elements / sounds of the language, but cannot follow the
dialogue (makes the correct sense of it), that’s why they have 聴覚情報処理障害.

間違えたら、すみませんね！
