A very small part of the world is gone, leaving vacuum. How does this affect its surroundings?

A small perfect sphere is suddenly gone. Everything inside is teleported somewhere -- through space or even maybe through time, we're not sure. It's a small sphere, just enough to fit a human sitting on a chair. The perfect vaporization affects everything -- most of the chair, large part of the desk, air. What's left behind is just vacuum. No flash, no explosion, no sound. (The fact that this can happen is the only part I can/want to handwave, but bonus points for a reality check here.)
But what happens to this space moments after it happens? What would a blob of empty space do when placed in the atmosphere -- precisely, in an office full of tech equipment. Would there be an explosion after all? Would it create an energy blast? Would it feel like a wind coming from it or going towards it? Could it do something to the laptops and phones nearby?

A very similar question was covered in What if series, applied to a glass.
Quoting from there:
We’ll imagine the vacuums appear at time $t=0$.
For the first handful of microseconds, nothing happens. On this timescale, even the air molecules are nearly stationary. For the most part, air molecules jiggle around at speeds of a few hundred meters per second. But at any given time, some happen to be moving faster than others. The fastest few are moving at over 1000 meters per second. These are the first to drift into the vacuum.
After a few hundred microseconds, the air rushing into the glass on the right fills the vacuum completely and rams into the surface of the water, sending a pressure wave through the liquid. The sides of the glass bulge slightly, but they contain the pressure and do not break. A shockwave reverberates through the water and back into the air, joining the turbulence already there.
In a few more milliseconds, it reaches the humans’ ears as a loud bang.
The bang will be pretty loud. I happened once to force open a vacuum chamber not yet fully vented, and though it was not in deep vacuum (just few millibar) it sounded like somebody had given a strong hit with a hammer.
Maybe the shockwave would be strong enough to shatter some fragile glass and damage some MEMS (like the microphones in the telephones).

If you're vacuum chamber did the sound of a hammer something $5m^3$ big would probably shatter all the windows of the house and the vase of your mother-in-law

The same thing that happens after a lightning strike heats up the air so much that the hot gasses expand, causing a partial vacuum where the lightning was: air rushes back in really fast because nature abhors a vacuum.
And we all know what goes with lightning: a really loud thunder clap that -- if close enough -- breaks glass and sets off car alarms when the rapidly in-rushing air bounces against other bits of in-rushing air and bounces back.
