Frequency

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!)

At it again, from another angle this time.

‘Old’ weapons. Or at least redundant, as a species traverses into space the new technology makes an old gun or even older sword/arrow/spear and so on useless and nearly powerless. The new weapons are ‘ray this’ and ‘beam that’ ‘plasma so and so’ .

Ofcourse this makes sense, the energy based weapons are far less wasteful and lighter, easier to carry and easier to handle. No need to sharpen weapons with a plasma blade and even then, why use close quarters weapons if you have access to stun, kill or poison rays and many more.

On top of that many civilisations prefer to forget their less then stellar past and make analog weapons obsolete. When the humans joined the council many expected them to do the same. They didn’t, production stopped yes, but interested people could still partake in lessons and the old fashioned ways were shown off in museums. Training to be part of a spaceship crew still included lessons in their old weapons as an opportunity to be prepared for going to “newer” worlds.

So with that in mind i have a few little vignettes ideas and for ease’ sake its gonna be on the same ship, the Serpentine.

Important crew:

Primoz, captain -Limoyh a four armed species-

Krag, second in command (brother of Primoz)

Kit, dokter -avian, bird like, she has feathers like a swallow-

Ortez, ASR (all species resources, human resources in space) -kiltak, insectoid species, think ants but exoskeleton-

Lugea, helmsperson (does the steering) -rock like alien-

Artex, engineer/mechanic 1 -also Kiltak-

And then our humans:

Kamari, navigator -Eritrean woman- (has cat named Sidra)

Markus, weapons expert (knows how to use them and upkeep, also shields) -Swedish man-

Petrus, mechanic/engineer 2 -Italian man-

Lilly, administrator/note keeper (learns languages for fun)-english woman-

Yes i know all of this could have also been accomplished by saying they are all from America… nope this is more fun. This is under the assumption that to get into the joint academy for space faring you need to be able to speak and write English.

Obviously there are more people on the ship but these are most important

~~~~~~~~

1. Sparring

Ortez was having a good day, the serpentine had left port and was making good progress toward their next destination on w-kl-18, referred to as deltax by it’s residents, for a routine drop off.

In port on Unity (the planet where the council resides and the universal court is) they picked up the final crew members among who a ‘team’ of humans. Pre bonded humans were supposed to be less chaos inducing and easier bonded with the rest of the crew. Ortez was rather happy the captain listened to him on this matter.

The humans had been more diverse than he expected and were currently what they called ‘settling in’. He was on his way to the rooms they had.

‘Stop it please we’ve been here less than 4 hours!’ The soft voice he recognises as Lilly’s is barely audible over the loud clanging sounds. Rounding the corner Ortez sees a terrifying scene. The two human males locked together with two sticks made of metal baring teeth at each other, with a push the olive skinned man, he remembers is called Petrus, breaks the hold and goes in low swiping at the tall mans legs making Markus fall over.

Ortez is about to intervene when without a sound the dark skinned leader of the group seemingly appears without a sound behind him and runs into the fray with a similar stick.

Whacking Petrus stick away from Markus’ throat she steps inbetween “stop it. You’re scaring our ASR. We want to make a good impression remember.” The men look right at him and both put down the sticks, Markus puts his hand up in a ‘wave’ “sorry about that, Ortez it was right? We were just sparring.’ Moving further into the room he uncurls his front two claws tapping at the metal poles “sparring with this? We usually only do body to body training, this seems rather old.” Petrus speaks up to that “ah yes those are old earth weapons, we like keeping up a bit of skill with several kinds as a side activity. Don’t worry tho, we train with blunt weapons.”

Not entirely appeased the insectoid looks to the imposing woman, who seems entirely at ease even though two people had been fighting. When she caught his eyes, she smiled that terrible toothy grin “truly don’t worry, like Petrus said they are blunt and it is a way for us to let of some steam and keep in shape. But next time we’ll do it in the training rooms… right boys?” Pinning the two men with withering stares they nodded quickly.

Ortez did not know humans released steam, but he felt right now was not the moment to go into that. Saying his goodbye he skittered to inform the captain.

This was bound to be interesting.

~~~~~~~~~~~

2. “The Roman empire”

“So you are telling me that at any given moment you could be thinking about a several thousand years old society that no longer exists and it would surprise nobody?” Artex was perplexed, when he and Petrus were working on the reactor core Lilly had wandered through and mentioned this old civilisation sparking heated debate. She thought the greeks were far more interesting but Petrus had been unmoved by her arguments. The other man speaks while pushing some buttons “well yea, the empire made great strides and amazing structures, Lilly just prefers the mythos of the greek while i enjoy the focus on millitary prowess.” Shrugging he looks up “don’t you guys have something like that?” Artex stretches his legs, all 6 of them in a wave like motion “not really, when change happened the history books were changed to make it seem like it was always that way” the human makes eye contact “wait so how do you know how to play -old civilisation- as a kid? We play fought with wooden sticks, wooden swords and branches we cut to look like guns…” that horrofied the insectoid, raised with violence like it was a normal thing.

Almost like they never left their dark ages

~~~~~~~~~~~~

3. Whats in a name (bit off topic but the idea just kinda happened)

Te very first time the humans were introduced to their new crew there was a bit of a hiccup. When Kamari introduced herself they looked up a bit confused but went further down the row. After Lilly they came back around and referred to Kamari as moon. Now Kamari recognised the strange look, they had translators that only had basic human translation, which means that her name “Kamari” which comes from Arabic and is a word for moon/soft glow of the moon, is translated fully but not as name so when they speak to her it translates out of their language to English which would be moon. This is luckily easily fixed with an update, but it was something that stil spoke of how new the human race was to the cosmos.

Her cat Sidra made them laugh as that means Star so she was the moon with her star.

(Random thought about how multiple human languages could screw with translations)

~~~~~~~~~~~~

Soooooo kinda had a 4th story that is pretty sad but also bad ass, but this is getting too long already

Imma write that in a new post over the coming days

Hopefully people like this, if you have prompts you’d like to see with this crew feel free to ask.

I need so badly for someone at Nintendo to listen to me; I know they don’t accept unsolicited advice or suggestion but hear me out PLEASE

I would literally do ANYTHING to be able to give Blathers the fossils that he wants for his own private collection PLEASE. It doesn’t even have to be for any kind of result or reward if that is too much to program in, but maybe you could complete HIS fossil collection for like a golden fossil trophy or something. I don’t know. I don’t need a reward, I just want to be able to give the man his fossils 😭 he does so much good and puts up with SO MANY INSECTS for the town’s benefit and he gets SO LITTLE in return and I want to make him HAPPY

Reblog if you just want the little science man to be happy 😭
