acoustic Duplo panel, the Story

2 techniques of echo management

2 techniques

In interior spaces, there exists 2 techniques of acoustical dampening for the effective control of echo. Or more specifically, the reverberation time – the long fade of an echo.

We have the traditional technique, of materials that by their mass – thickness – absorb the energy of soundwaves.

Then we have diffusors. A whole different technique, where uneven surfaces scatter (split up) soundwaves. Which, from this surface are then reflected as many, many, smaller waves – with many, many, different paths.

Energy conservation – Low hanging fruit

Energy conservation – Low hanging fruit

We as human beings do things out of old behavior – habits – sometimes without reflecting over the logic of our behavior. I will present situations around energy saving behavior, which I have philosophized a lot about.

Are you familiar with the term “Low hanging fruit”? It means things that are easily reached, things that are available at closest reach.

I believe habits are formed because of the road of least resistance. In certain ways, things are simply easier. Therefore, there is a resistance to change a habit, a behavior.

And, if to change, there must be an certain experience of pain.

The Elephant, and the Mouse

In Finnish media, a while ago.

Not important who Navalniy is, what network he has or not. For the record, I do not value all he says; he goes a bit too far in his ideology.
Important is how he is treated by Putin and his klan of officials.

Not in particular that they do not use his name, only referrals pointing to him.
Particularly important is the energy they spend. The time, the (tax payers’) money, to keep him from being an electorate.
