The most silent keyboard?

Question

Keyboard

Question from my friend, a biologist. He conducts some drop dead experiments with all sorts of different little animals (I forgot which ones, but it doesn’t matter). So, for some reason, these little animals are stressed by some sounds, in particular, from the sounds made when typing the keyboard, which means that experiments to measure their intelligence or something there have not yet been successful. And the researcher needs to print. He - to me, tyzhprogrammer, advise.

In general, are there the most silent keyboards in nature? What models? It is clear that it is probably impossible to be absolutely noiseless, especially if the animal's ear hears a hundred times better than a human's, but still. Well, he put a cloth under the keyboard, it helps, but not in the way we would like.

Answer 1

There are silicone keyboards, they can still be rolled up into a tube - I think it will be quite silent, and most importantly - they are affordable and inexpensive. For example here - https://aliexpress.ru/item/32672663177.html?spm=a2... . Google something like Flexible Keyboard
But - if the table is poorly fixed and the little animals are so sensitive - then the vibrations will be scared of typing.

Answer 2

google for "glass keyboard", something like this

Answer 3

Almost all membrane keyboards are quite noiseless - here is a review - https://expertology.ru/13-luchshikh-besshumnykh-kl...
One of the best, and quite quiet - apple magik keyboard, but if not OSX, then you will need to get used to layout.
Well, the most relevant one (I own one myself), but you need a flat surface - https://aliexpress.ru/item/32637249455.html
But in general, it's better to go to a big store and knock on the keys :-)

Answer 4

1) Keyboards with drawn keys.
Usually these are capacitive keyboards (they are also "touch"), on old household computers there seemed to be such. Because they are the cheapest. Now they seem to be also produced, but more often for all sorts of terminals and similar needs. Maybe you can find for computers.
In principle, membrane ones can also be not with full-fledged, but with drawn keys. It seems that on some terminals with printed (drawn) keys there are bumps - they are probably membrane ones. Rubber keyboards are also probably membrane. True, such keys are inconvenient to press when typing multi-book files. Capacitive will be more comfortable.
2) Use a tablet or phone with a virtual keyboard. Essentially the same capacitive, but configurable.
