No doubt that I get a greater sense of nuance, detail and the soundscape when the eyes have nothing much to do. I think we are so visual that that sense can be pretty dominant, occupying a lot of the mind's attention. My wife and I, our first several years as full time potters, we inadvertently segued into the night shift. Later we realized that it was because it was less distracting visually, auditory, and energetically, making it easier to focus on the work and get absorbed by it. I am not positive, but as far as I can tell, my power is treated enough that it isolates the line racket. So I think it is sensory allocation so to speak, which could easily be enhanced by the things you point to. After all, who do you know who thinks they are a great multitasker, and who does each of many things as well as they would have had they given total attention to it.

I love to hear the music in a dark, quiet room.

I'm thinking of the word synesthesia right now... That's cross- sensations... I had a conversation with a respected audiophile once, and he said that he could 'hear' light... He explained that light was a sort of static that got in the way of hearing the music better...

From a physics point of view, there are more particles in the air at night. Since there are more particles in the air, the air is more dense and carries the sound waves faster and farther...

I still think it's a least in part due to our evolution... It makes sense that, if our sense of smell is not good, and our vision is not good at night, we would be genetically 'selected' for better hearing at night... (m.)

I get my PPP today. Looking foward to late night quality listening in the daylight.

My guess is that it is a combination of things - cleaner power, it is probably quieter, people are more relaxed, etc.

I`d go along with Lon...my Isotek power plant was an eye opener. I find  night time listening  enhances  the receptors and  have an idea that atmospherics change in the evening, you dont need so much volume,  and when your day is done you allow yourself to become more accesible to cerebal pleasures.

Well, since changes take a long, long time, it seems at least possible that our genetic selves have retained some of our primal characteristics... I don't think we've changed our basic bodies much in the last 40,000 yrs or so...  (m.)
