[Request] How accurate is this?(i.redd.it)

Also, that's supposing all the cats are in exactly the same place

Exactly, distributed evenly, this sounds like <1 cat meowing just about everywhere on earth

As opposed to the 2 or 3 "meowing" outside my window some nights.

Exactly. At any given point in time, there are countless billions of things making noise all over the world. If noise levels worked like this for things that were far apart, we'd be deafened the moment we were born.

I love how the mother has the strength to withstand the excessive energy in your scenario

She's also been deaf since birth, obviously

WHAT?

Hers, or yours?

Not necessarily.

It assumes that all cats are at the same distance from the listener as the single cat that the 70dB figure comes from.

Let's say that each cat needs an area of 200cm^{2} to poke it's head in to meow. This translates to 40M m^{2} for 2B cats. Thus, to arrange 2B cats in such a way that they're all the same distance, you'd need a sphere around 1.7km in radius (surface area of the sphere needs to be 40M m^{2).} I don't think the average cat can manage 70dB from a distance of 1.7km. If you squish them all togethar and squeeze their heads into an area of 100cm^{2} (which should be doable without causing pain/injury for most of them) the required radius is still over a km at 1.2km.

and by exactly, we mean EXACTLY, cats in full superposition, not just herded into a big amphitheater.

That's like probably twice as hard as herding them into any room.

Right? 20,000 could possibly have taken off at the same time around the world. Over 100k take off each day. Under the right circumstances it could have happened. Since it is dispersed all over the globe, we haven't noticed some massive blast.
