In Koe no Katachi, Shouko Nishimiya uses hearing aids. She's deaf, so can she actually hear something or not? I have read the manga but didn't watch the movie, so I haven't seen any clue about why she is using hearing aids. For what purposes did she use hearing aids in the first place?

I think it's never mentioned exactly, but the only reason she is using hearing aids can be that she can hear some sounds, but her hearing is bad enough to be considered clinically deaf.

We can actually see her several times in the manga reacting to loud shouts and noises.

There are also some pages in chapter 51 that show speech bubbles from her point of view (one of these pages below), so this also might prove that she isn't completely deaf.


  • i read the indonesian version ( licensed ) and i have never seen the bubble speech looks like this ( in my version, the translation didnt looks like this, fince grammar speech, but this one looks ugly )

    @Gagantous The page above is from the Crunchyroll version, but the official English release by Kodansha looks pretty similar. In the original Japanese version the text is similarly erased a bit, you can check out the raw here

Shouko uses hearing aids because she's deaf. They're meant to assist anyone with hearing loss of specific kinds to allow them to better identify sounds.

If you're looking for a clue, in the first chapter of her introduction, she plainly tells the classroom that she's deaf.

  • i forgot about this one... she sure did tell that she's deaf

  • Well, the reason she tells straight off the bat that she can't hear might be because she might have learned through the years that it's just easier this way for everyone, compared to saying "I have severe hearing loss" or "I am almost completely deaf." || Also, I don't think for someone completely deaf the hearing aids could have any kind of help. || But actually, Shouko's level of deafness isn't actually clarified anywhere and the community is divided regarding it.

    @Gorzius: Having worked in an accessibility center in college, I can tell you that hearing aids at least help somewhat. The phrasing isn't going to be as clear as a non-deaf person, but it will be somewhat understandable. This is why in your picture below you can mostly understand what's being said, but it's neither grammatically correct nor phonetically correct (it's slurred in parts and patchy). This also explains why her speech is similar; it's how she had heard herself talk. No, the manga doesn't go into what degree of deafness she has, but we can infer.

  • @Makoto I see. I have looked around for at least 15 minutes looking around about complete deafness and hearing aids but haven't found this. Reevaluating the page below with the information you just provided I guess the mangaka's intent was to make people feel the hardships of deafness to some degree.

I'm a hearing aid salesperson! Shoko has some degree of hearing somewhere. She uses the "universal communication" method which is generally about getting it out and making yourself understood. Some people try only hearing aids, some people try only sign language and some people use both. Visual cues and hearing cues in unison are clearly enough for certain moments of short speech for Shoko where she doesn't have to write or sign.

That being said, when Shouya yanks her hearing aids out and she bleeds on the right side, it's implied that he perforates her eardrum or causes other structural damage. A perforated eardrum is contraindicated in some countries with a hearing instruments which is why she has to wear a left side monaural hearing aid for the remainder of the time.


She may have some degree of hearing, especially if she can hear certain loud sounds as shown in both the anime and the manga. The term "deaf" can be used as an umbrella term for all people with hearing loss, whether that be mild, moderate, severe, or profound. I myself have moderate hearing loss and wear hearing aids, and they help me hear almost as well as a person with normal hearing. Most people with mild or moderate hearing loss prefer to be called "hard of hearing" instead of "deaf" to prevent any confusion for people who aren't completely educated on the topic. Shouko most likely has severe hearing loss due to the fact that she responds to certain loud sounds as I mentioned before.


Even if someone is deaf they may use hearing aids to let them hear a little bit. This will help them not have to be completely deaf. I use hearing aids because I have hearing loss but I was born deaf. I failed my hearing test as an infant. :( so the hearing aids probably assist Shouko. She might not be completely deaf or she would have a cochlear implant. I have hearing loss so I know a lot about this topic.

  • They also might not have known much about hearing loss when they created the show. Mar 15, 2021 at 16:55
  • So it might have been an honest mistake. Mar 15, 2021 at 16:57
  • I am not sure... but possibly... it could be that they didn’t know the difference between hard of hearing and deaf. I dont know but it is a possibility. Correct me if I’m wrong Mar 15, 2021 at 17:00

I have hearing aids myself so I can kinda understand, I guess?

Her condition of hearing must still let her hear some sounds, specifically louder sounds. From personal experience, the hearing appliance can help you hear sounds that you can't normally hear, making it a lot more clearer and reassured. Her hearing is considered quite severe, since she uses sign language to communicate quite often throughout the movie.

Her hearing aids will really help support her, they would make her feel comforted, since they will allow her to hear to some extent and she has something to rely on to help her hear rather than have nothing to help her. She also flinches at loud sounds, because listening to a bang or a general loud noise is like listening to it x10 louder through a clear microphone and then hearing that reflected sound through a pair of earphones and sometimes the noise wouldn't even be that loud, but it has the same effect (not a great experience).

Anyway, yeah, she has severe hearing loss and likes to be supported by hearing aids.
