> a signal we recognize as music.

Maybe. That depends on the drummer.

Queue up the Drummer jokes!................

How do you get a drummer off of your porch?
Pay him 10 bucks for the pizza.

“But once those vibrations stop, the signal disappears. Now imagine a drumhead that’s incredibly thin, only about 10 millimeters wide”

I suspect present drum skins, and original drum skins from Africa are quite a bit less than 10mm thick.

(you know, you do not have to hire Leftists for technical publications...there is no law to that effect)

Now imagine a drumhead that’s incredibly thin, only about 10 millimeters wide, and covered in tiny triangular holes.

Huh? That’s a drumhead a centimeter thick. That would be the thickest drumhead ever made. It would be thicker than the chunkiest cell phone.

I suspect this is another case of a know-nothing “journalist” writing copy they don’t even proofread, about a subject they don’t understand.

I suspect they meant micrometers. I tried looking at the original article in “Nature”, but it’s a paywall site.

I was thinking the same, micrometers, but maybe nanometers, thought that’s quite thin!

This undermines a fundamental part of drumming.

Electric drum sets save marriages because they have a volume knob. LOL

Interesting. I wonder if there is a sound threshold above which is necessary for the phenomenon to occur. But it makes intuitive sense...a thinner membrane with less mass will conduct movement much farther along its path..(I think as a non physicist)
Good things:better sensors
Bad things: better sensors to spy on you.

I also wonder how often Autocorrect is involved. If you’re writing on any Apple device, it’s always lying in wait, just waiting to strike. I fight with it constantly, and frequently see it actually change correctly-typed words to entirely different words after the fact, based upon what it (mistakenly) believes is the context of the sentence. It’s really poorly designed.

I saw that, too. Typical lack of attention to detail that is everywhere these days. Most college graduates can’t even spell, much less write coherent passages.

Or maybe it’s referring to the world’s smallest drum, made by whoever made the world’s smallest violin.

Yeah — it is describing research not a finished product.

I understood it fine but I am used to being abused by these editors and their poorly written articles. :-) AI should be an improvement in many cases.

If AI achieves nothing else but ending the epidemic of using an apostrophe before every “s”, especially in plural forms of words, it will have achieved a great victory for literacy.

I suspect the problem is with a reader. There is a difference between ‘wide’ and ‘thick’.

How do you know when a drummer is knocking on your door?

The knocking gets louder and faster!

Drummer here. I believe they meant mil. Drumhead thickness is measured in mil, which is one-thousandth of an inch. For example, the popular Remo Ambassador drumhead is 10 mil, or .01 inches thick.
