Modern sound equipment and hearing difficulties, no tone controls?

    As we get older, the high frequencies drop off and hearing problems arise.

    Tone controls that would allow you to tweak the sound,taking base out and boosting high frequencies seem to be few and far between,particularly active tone controls.

    Even setting tone on some TVs that allow it , remove the setting if you go to Bluetooth or tosslink optical outputs.

    Gamers like extra base for explosions etc, with tone setting on headphones a rariety or non existent.

    Smart speakers accentuate the problem incorporating

    base reflex ports to give the impression of larger outputs,by increasing base frequencies at the expense of HF.

    Bluetooth doesn't appear to carry EQ settings,only a flat response. My smartphone has a very good EQ adjustment menu,but only on headphone output, which is removed if you go to Bluetooth. All very well spending a lot on an amp to reproduce 20khz,, but if your hearing drops off at 4khz, a tone control is a tremendous help.

    Interesting article in march IEEE Sprectum magazine, on improving sound and Haptic Feedback on our devices,replacing moving coil loudspeakers with Piezoelectrics.

    Company Synaptics,say "We expect to see our chip in Smartphones, wearablesandlaptop computers by the end of 2024.

    Basically they say ,rather than the sound coming from the sides of the device, it will come from the direction of the display screen.the transducers,speakers at the device rear.

    They even suggest the possibility, that when a touch,or,even reasonably loud ambient noise, flexes the display panel,it will also flex the transducer generating a voltage.This electrical signal could be harvested to charge the devices battery.

    May be of interest on computer,and audio threads,or not?
