Home office lighting levels

I do almost everything on a monitor. I don't have a backlit keyboard, yet. 

 

I was trying to figure out what an appropriate lighting kevel was. I found there are now apps to use your cell-phone as a light meter.

 

IES doesn't call out a level for strictly using a computer screen 8 hours a day or more.

 

I think 30 foot candles is too much. That, and on a personal level, my eyes are old. They don't adjust the way they used to.

Low, indirect, multi source.  I have three LED bulbs around 5-6w and about 3500K.  MacBooks have a light sensor so the monitor color temp and brightness adjusts to ambient.  The Window is mostly covered by a thick sheet of foam insulation.  Most importantly, nothing that can reflect from a monitor, in the slightest way.

EDM-pop at low levels, and it has to be stereo.  How would I know?  Tried using a single HomePod and it made me insane (quality is excellent, wasn't that).

Was it kinda like having a stereo out of phase?

Oooh, yes.  Insanity-inducing.  And I think it uses directional phasing to pretend to be stereo.  It has seven (I think) speakers in all directions.

 

I *love* the HomePods in the garages for listening from afar and filling the space, but not close by.

There's controversy on that practice, and some evidence of harm.  It's fatiguing and distracting when awake.  It's why NC headphones on a plane reduce jet lag and travel fatigue.

Does Noise harm your Brain?

Well yes. It turns out, the continuous background noise also known as white noise which comes from machines and other appliances, can harm your brain, it does so by overstimulating your auditory cortex– the part of the brain that helps us perceive sound.

And it’s even worse in children. 

Dr. Norman Doidge, a psychiatrist, researcher and faculty at the University of Toronto’s Department of Psychiatry, in his book The Brain That Changes Itself cites one disturbing study which showed that the closer children lived to the noisy airport in Frankfurt, Germany, the lower their intelligence was.
