Friend BWC

Just found some Acoustic Research speakers by a dumpster in great shape. Not worth much, probably just ok, but I'll have some fun with em. Jan 18, 2023

        With the exception of 2x on boring work training videos, I don't understand "speed reading" content that's intended to please us emotionally. Why would I fast forward through enjoyment?

        Sometimes the speed adds enjoyment for me, or rather, reduces the opportunity for distraction, which in turn makes it a more immersive experience. I am definitely ADHD and was medicated for several years (I was a good kid and took my meds as directed), but had to stop for cardiac reasons.

        This is why almost every headphone I've ever considered is closed. Spending some time with one on and no music playing helps appreciate just how valuable good isolation is, even if it can't block everything.

        I've noticed a trend in the market towards constantly using lighter, thinner, more efficient materials across driver technologies. It makes sense on an intuitive level, but it's been refreshing to explore the opposite approach too. Lots of novel textures and sounds I never thought I'd hear from a headphone.

        Aside from the obvious duller transients and lesser macro dynamics I have a speculation that stiffer surrounds yeld more plankton and texture and vice-versa (soft surr> less plankton/texture but more clarity).

        Would love to build headphones in the future just to play with those interesting variables.

        Yes of course - it is a wiring thing. From what @E_Schaaf is describing, this could be what's going on, or it could be simile as you put it.

        I do have a sense of the sound of a material through my fingertips even when sound isn't playing through a transducer. The transducers in this context are my nerve endings, and they're inputs instead of outputs. Either the wires are crossed or I've just trained myself deeply enough that I can't separate my expectation bias from my immediate perception. :Shrug:

        I think it shows experience and maybe some special cross wiring - but it seems like what good artists/engineers/specialists in a specific field experience with intuition. You just know what could work to solve a problem/where it comes from/what would be good design just by looking at it, way before running a simulation or measurement. Just hours and days and years of time spent and its a good thing!

        I'm sure many people find these comfortable. Compared with speakers, I find /all/ headphones uncomfortable ;) but I'd rather have the whole ear type.

        (also, although it's not great for music, over-the-ear feeds my hearing aids too. This is good for you-tube videos with speech.)

        Voice coils generate magnetic fields which is directly due to the current. This means you want as low a resistance possible. So coils are made from aluminum, copper and even silver. Nickel is used for magnetic lamentations but don’t conduct any current. I don’t think you would really see it used for transducers unless it’s a field coil

        I'm fairly sure... You know how after a heavy lift or standing up too fast your high frequency hearing can become temporarily muted? It's like that, but more subtle, and longer lasting. More testing required, maybe I'll take blood pressure a few times over the course of the day and see if there's a correlation...?

        I'm the last person to comment: my HF hearing is permanently muted and I don't exercise. But I was once addicted to pottering-about rowing. And there was enough exercise to create arm muscle. And the mood change was more than just the river environment.

        Sadly, for the purpose of this research, I never took music with me.
