Off Topic But Ochako Is SO BEAUTIFUL On This Season Omg

I could talk about them for hours <3

Y'all mind if I talk about Present Mic's quirk for a second? Great.

So, my partner and I have been having Erasermic brainrot lately, and while we were binging content with them, I became interested in Hizashi's voice quirk. I began searching stuff about how sound/volume works, and linking it to his canon stuff.

I'll just say, the info I found makes him a pretty scary guy. It's a shame he's so underused in both canon and fanon.

Frequency

First of all, I want to talk about something everyone knows about him: his quirk is potent enough to shatter glass. Now, when it comes to decibels, it's always important to consider the time and distance a certain note is held for, since these can impact the "hit" a certain sound wave can have when influenced by effects such as the air or vibrations.

(Please keep this in mind for the reminder of this post)

When it comes to glass, however, it breaks almost instantly under the pressure of his voice. Our most constant example of this is the man's poor lenses, but there is a scene I'd like to talk about the most, it being he one where he completely shatters Shigaraki's tank.

One might argue that the glass was already weakened from Mirko's kicks, but that's honestly part of something that makes this so impressive to me; Mirko's legs are strong enough to straight-up rip a high-end Nomu's head clean off, yet this tank was tough enough to withstand two attacks from her - including her ultimate move - before starting to leak; and the fact she was heavily injured doesn't fly here, as we very clearly could see she wasn't holding back one bit.

Now, let's get technical.

According to Google, a normal tone of voice would be around 50 decibels, while the required to shatter glass would be a minimum of 105. For comparison, that's roughly the same volume as a jackhammer. Now, you might be thinking, "Oh, that's not so bad! Some singers can do that!" and you'd be right, but there's also some other things to consider. Allow me to explain.

Some singers can reach a pitch that can make glass vibrate enough for it to break, but I've personally only heard of this happening if the person has their mouth close to a smaller, empty cup, and even then the volume would be distributed around. Hizashi, on the other hand, was standing several feet away from this reinforced tank and was able to shatter it immediately, using the directional speaker around his neck to aim the volume. This would naturally require for him to hit even higher decibels, specially when you take into consideration that one's frequency must match the glass' for it to vibrate, which drastically increases when it's dampened. (Read next topic for more info on this)

And then there's his glasses which, like I've stated before, are the most common thing he breaks with his voice. Obviously, this is not directed and it's not a total shatter, but there is something to be observed; say, did you know the necessary volume for lenses to crack, when not being directly aimed at, would be that of a nearby shot from a highcaliber gun? That's roughly 140-170 decibels.

Harm factor

Boy, oh boy! I'm betting most of you were looking for this part when you clicked the read more, right? Look no further, I've got you covered, you just better remember what I mentioned before about distance and duration.

Hizashi's parents were unfortunate enough to have a mutant child that was born with his quirk already active, and I'm willing to bet a newborn doesn't have the slightest bit of control over a power as destructive as a sonic-powered voice, which immediately resulted in everyone in the room bleeding from the ears.

Sound-related ear bleeding is most commonly associated with a ruptured eardrum, which can happen at around 150 decibels and is about the same as a jet engine taking off. While a baby most likely unleashed his maximum voice power on the first breath, I believe something like that would, thankfully, only develop fully after puberty, just like with non-powered people like us, since his quirk is a drastic intensification of a common function and not a new ability altogether.

With that being said... The Finals Exam.

In this, Hizashi was standing very far and, even with the directional speakers, there were many obstacles in the way that kept him from landing direct soundwaves on the students. Regardless, Jirou's ears bled in less than 30 minutes being exposed to this.

This could have happened due to the fact that she has a hearing quirk, which would make hers much more sensitive, but let's study this, shall we? We don't have the exacts of what happened there, but the students are visibly uncomfortable upon the first soundwave, which would suggest it was at about 120 decibels upon impact (with 85 already being enough to cause damage to your ears) and being emitted even higher by him, considering distance muffles volume. Still, I think all that would be nothing compared to the scream he let out after those bugs started crawling on him, with how unfiltered that was.

With Jirou, it comes to no surprise this volume at this distance and time almost rendered her deaf, and realistically would take several months of healing time. How much do you want to bet Hizashi got a solid scolding from Shouta? I mean, it was supposed to be a challenge, but homeboy came this close to breaking her quirk.

Another thing I want to point out is that his voice is powerful enough to actually fucking launch people, and this only happens due to an event called acoustic trauma, basically meaning Hizashi can surpass supersonic levels. Although, it's important to note that this effect is caused mostly due to pressure and not so much as sound, so while it's not freakishly loud (about the same as thunder), it can still cause hearing and psychological damage.

! WARNING !

The following part contains graphic mentions of injury, and death. Do not proceed if these are sensitive topics for you.

Now, we look at the disturbing side of Hizashi's quirk. Buckle in, because it's a wild ride.

Remember what I commented earlier, about him having to hit even higher frequencies to be able to shatter Shigaraki's tank? First of all, as the doctor was sent flying, this qualifies as supersonic, but that's not all. To shatter such a protected tank, with liquid inside increasing the density, he'd have to hit over 200 decibels; which is considered extremely dangerous and most definitely fatal, as the threshold of pain is of 115-140 - this can cause damage such as crushed ear bones, ruptured lungs, or embolism. For comparison, this would come close to standing right next to a Saturn V Moon Rocket during launch, and is no longer considered a "sound" due to the vacuum.

With that being said, the man came very close to dying by Hizashi's hands (voice?) twice. Not only was he so close during the lens incident, literally being inches away from his face and in risk of getting his eardrums ruptured already, but if Mic had decided to raise his voice even more during his rage, it'd be possible for the frequency to make the doctor's inner organs malfunction, or straight-up burst from the pressure.

But that's not the worst part.

After establishing that the lethal amount of over 200 decibels would be necessary to shatter the tank given the circumstances, if he exceeded 240 and the doctor happened to be in the way of this, it would be enough to cause his head to explode upon impact. That old man better be grateful that he was standing a feet few away, and that the supersonic blast blew him away a bit more, or it'd be an immediate game over.

With all this being said, how devastating would it be for this guy to scream his rage out?

(Please keep in mind that many of the extreme cases in this are actually impossible to happen in a real-life scenario and are purely speculation!)

Do you support Ochako x Toga?

Maybe 🙂‍↕️.........ONLY maybe.......

He looks like the type of dude to say hey bbg then have a series of crunchy coughs 💀🙏

I’m in so much denial. Aizawa prob dumped his ass and he stole aizawa’s hair as pay back💀

oops! more will

Jirou and present mic interaction my hero justice 2

I love the way he kinda bullies her but also supports her😭

Dadmic‼️

Anon that said Mic is attractive with fanart, with his hair and glasses down.

(Note I don't know how this may turn out. If it sounds like I'm anger. It's not to you it's at other people. I promise)

I agree with you. I think he is really attractive, but a majority if the fans, it's feels like, don't agree with us.

I once was talking to my friends about how I thought Mic's was really good looking in the new leaks(this is when the Mic suit leaks came out) and they told me "But Aizawa is hotter" Orr "No" and repeatedly shut me down. I had to agree with them, just for them to hear me out. Then told me more or less that I was wrong.

So I agree with you, Mic is attractive, but people don't care, and will hold him more accountable to the shit he does, then someone like Aizawa.

I don't think that it's fans not agreeing that present mic is good looking but more of fans developing a tunnel type vision so whenever present mic is brought up aizawa would eventually be brought up into the conversation it's rarely vice versa though. I do very much think that this is because mic as a character barely has any screentime to himself and is usually used to prop up aizawa instead of being an independent character.

Yeah mic looks really good in the suit and he is slept on in chapter 425.

However, I would go as far as to say that the criticism that mic gets is actually unfair.

1) he got criticism for his reaction to finding out about yuuga being the traitor but after all the traitor put everyone in danger and literally indirectly caused the death of midnight and aizawa getting injured in the usj. Present mic at the time also didn't know yuuga's situation and he still had 100% right to be angry

2) he got criticism for calling out bakugo in the sports festival but he was valid for doing that. Bakugo was being harsh and incredibly aggressive

3) he got criticism for him not accepting that oboro is kurogiri but present mic unlike aizawa never got time to process and heal from the trauma he simply shoved it down he cracked and even then it was extremely valid and understandable where he came from

4) the way he attacked Dr garaki was yes indeed violent and he shouldn't of done it as a hero but you bet I would be out for blood if some creepy doctor turned my friend into a nomu ending his life while that doctor has a bloody immortality quirk.

Also, even if characters are thought to be hot/good looking sometimes it even back fires because not only does it sometimes make people forget about the characters actions but it also makes people just focus on that one quality, sexualise the character and sometimes even forget about the characters purpose or proper role in the story.

Midnight headcanons+ some hizashi, aizawa and their friendship

Has a serious love for animals, she will save any animal she can. She’s even got a bird as a pet because she saved it, She knows she has to let the bird go at some point tho. She has a pet hamster aswell.

She calls all her friends nicknames that she’s made up or the simple pet names like “sweetie, darling” ect ect

She knows hizashi has mummy issues (my au) and she tries her hardest to be like a mother to him. Even tho they mostly act like siblings.

She did want to have kids, and have a family. But her love of her life died.. (Oboro)

Since aizawa left after graduation (I’m aware that isn’t canon,I think.) she didn’t want hizashi to be all alone so she did all she can for him and hizashi did the same back. They had to be there for eachother since no one else would be, she tried to help him through his alcoholic stage.. help him talk things out. But hizashi is a very closed off man and didn’t want nemuri to worry.

Her mother is Russian and she has a big brother, her dad is half Welsh, rest Japanese. So she isn’t fully Japanese. She also has some daddy issues and she doesn’t see her brother that much but she always visits her mum when she can.

Goes clubbing with MT lady occasionally. She ships kamui woods with her so she always asks how they’re doing, one day when MT lady said they started dating Midnight nearly started crying.

Her female students are like daughters to her. and she sees the male students as annoying little siblings but she loves them to.

She’s feels insecure about not having a boyfriend as she often hears “she’s such a slvt yet she has no boyfriend..” ect. But she reminds herself that she doesn’t need a man, but it does way her down sometimes.

Adores green tea and has a love for plants, she has plants in almost every room in her house.

Everyone assumes her favourite colour is purple but it’s actually red, falu red if we’re being specific.

Pansexual and once made aizawa and hizashi go to a pride parade

Voice note type of person, she rarely sends messages it’s almost always voice notes. Her and hizashi’s messages are just voice notes

Lover of Barbie and k-drama, watches k-drama with hizashi, sometimes with aizawa. She simps for atleast nearly every man unless they are super ugly, she sometimes even simps for the woman, thinking she can be a better boyfriend 😭

Secret lover of football and likes to watch it but no one knows😭

Loves to do hizashi’s hair, she’s sometimes jealous of his hair. They do eachothers hair sometimes.

Use to be a makeup artist when she was 18-21

Wishes she could understand villains more, especially toga.

Acts like she’s pretty but doesn’t feel pretty.

Has piercings and 2 tattoos

My favorite flavor of erasermic is Aizawa being all 😩💞✨♥️💗😍💫❤️‍🔥💖 on the inside everytime he sees, hears, thinks about Hizashi, but on the outside, the only reaction outwards is 😐-> 🙂

Rendering save livessss!!!! Tbh tysm parako (my fav nagito lover!) from yt literally you inspired me sm I only know how to do lighting and colour stuff cause of you :3 !
