    Musical Realism and the Performance of Our (Aging) Ears, Part Two

    Issue 165

    It appears my earlier essay on declining hearing (in Issue 160) touched something of a nerve, so to speak. I appreciate the many thoughtful comments it prompted. Perhaps I should not have been surprised that they focused primarily on the question of hearing and using hearing aids, and not so much on how our changing hearing intersects with those recording and playback qualities, whatever they are, that result in a realistic representation of actual musicians playing in a space.

    While I respect the expertise of the industry insiders whose work appears in Copper, I suspect many of those reading are, like me, laypeople who may be uncomfortable speculating about things that are outside our respective wheelhouses. And in this case, those things may be unknowable anyway – as I’ve mentioned before, if the secrets of great sound were known to one and all, every recording would be wonderful, and we know that’s simply not the case (though I do believe that, pop music’s compression and loudness wars aside, there are more good recordings issued now than at any other time in the industry’s history). Or it could simply be that hearing loss is intensely personal and potentially frightening, especially to those who take great pleasure in music and sound, and that fact elicited the need for people to share their own experiences. Community is comfort at times, or in this case at least solace.

    But before I leave the question of perceived recording quality completely, I want to touch on something that editor Frank Doris wrote in his earlier Copper article on hearing loss. His comment, shown below, speaks to one particular aspect of the ability to discern quality in hi-fi, even with declining hearing:

    “We’re constantly comparing the sound of our systems with the sound of reality as we perceive it. We know what our systems should sound like, whether hearing-impaired or not, and configure them accordingly.”

    What most of us search for in the reproduction of music in our homes is a reasonable simulation of the real thing. That goal is constant – it doesn’t change with age. Our hearing performance does, but many of us are finding that, as generally regrettable as diminished hearing is, it doesn’t matter as much as we’d expected when it comes to what we value in our sound systems. I believe the reason is that our yardstick for subjective measurement of the system’s performance has changed as well. What I think Frank was saying (and he may correct me if I’ve misconstrued his intent) is that our perception of the aural world around us is the only auditory standard we have at any given time. [No contradiction, Craig; you’re right – Ed.] When our ability to hear diminishes, then our perception of the real world, the standard to which we hold our systems’ performance, diminishes too, as unappealing as that might sound.

    The fact is, it’s physically impossible for an old person to utilize a young person’s perception of reality as a standard against which the old person measures the perception of his or her sound system. All we know is what we ourselves perceive. At any age, the goal is for the system to conform to our contemporary standard of reality. The fact that many of us believe our systems sound just as good or better now than when we were younger appears to confirm this, and it speaks, at least partially, to my earlier premise that extended high-frequency response is not the primary auditory cue that results in perceived realism. The flip side of that coin is that our diminished hearing may also be masking certain undesirable performance characteristics that had been detracting from realistic sound. But that’s a rabbit hole I don’t care to go down.

    So where am I now in my own journey? At my last writing, I was waiting on delivery of a pair of hearing aids. I won’t mention the manufacturer or source, other than to say I did not consult a certified audiologist, but neither did I go the full-bargain route of ordering on my own from the new proliferation of internet-marketed devices. I don’t mean to disparage either approach – I simply decided that my degree of hearing loss didn’t warrant the former, and I distrusted my ability to guide myself through this maze, without any help, of the latter.

    I’ve now had my devices for a little over two months. They’re of the “open fit” variety, where there is no full occlusion of the ear canal. I use them every day, and they’ve helped in most day-to-day situations, though because we’re not entirely post-pandemic, two of the circumstances for which I got them – hearing my dining companions in a noisy restaurant, and understanding speech clearly in large public meetings – haven’t presented themselves yet for evaluation. But my return privileges last another four months, so I’m sure there’ll be time before that deadline to try their performance in those environments and judge them accordingly.

    Day-to-day, I think I’ve come to terms with the aids, and I can appreciate what they can do, and what they can’t. It took some time to adjust to them initially. It was very easy at first to be distracted by the new hypersensitivity to sounds I’d become accustomed to not hearing, like rustling of nearby papers, or the sound of walking through our home (pops and creaks in flooring, shuffling of footwear on carpets and rugs). Besides training of the brain, that adjustment has been helped along by the provider supplying a remote-control software program through which the devices gradually ramped up to my prescription level, tuned ultimately to offset my measured losses. That process took about three or four weeks to complete.

    The biggest problem I perceive with them is an unnatural sound quality in high frequencies that is akin to a slight buzzing, like there’s a loose screw vibrating in the rim of a speaker basket. Being a sometime guitarist, it occurred to me one day that it’s very much like the dreaded B string fret buzz, but applied to all high-frequency sounds. I’ve confirmed with three other users of this device that they hear the same thing, so I think I can effectively rule out a faulty sample. And my brain has already tuned this sound out on most human speech, but on certain musical instruments, like piano, it can be quite distracting, sometimes making notes seem unnaturally bright, other times making it sound almost like the instrument is unstable or wavering, like it’s under moving water. Its severity, and in fact its very presence, can change from moment to moment, which almost makes me wonder if there’s some bit of phase-shifting taking place.

    I know from several of the comments left in response to my original essay that there are some manufacturers who may be more capable of producing devices better suited to music listening, or audiologists who are good at fine tuning devices to eliminate or reduce this or other effects for those who must use their ears critically all the time. I chose not to go that route for now, since, as I’ve mentioned before, I have no problem extracting maximum enjoyment from my sound system without hearing aids – I simply take them out when I listen to music. If it gets to the point at which listening without them ceases being enjoyable, and I find the need for hearing assistance under all circumstances, I may reconsider.

    And that may happen in time. I’ve had a brief glimpse into that possible future, and it was frightening. One day, several years ago, I woke up to a general “stuffiness” in the right side of my head (though not “stuffy” in the sense of any kind of breathing congestion). I didn’t think much of it until I realized while listening to the radio on my morning commute that my right ear was hearing at much lower amplitude than the left, and the lower frequencies of the right ear were especially diminished and badly distorted. Sounds in general, especially loud ones, were extremely annoying, like trying to understand speech in a reverberant space while blocking one ear (a pastime of bored students everywhere). By the time I could get to see my doctor, it had cleared up on its own, and he couldn’t find the evidence of anything amiss. Well, that’s happened again, several times, just during the past few weeks. Each time it’s “fixed” itself within a day or two. Just by chance, it happened last month while I was seeing the doctor for other reasons. After a lot of peering, poking and prodding, he told me it was due to a small bit of fluid buildup behind my eardrum that was not being drained properly by my Eustachian tube. He said that a decongestant might help, but said it was also just as likely not to. And so, the condition remains, for now a thankfully sometime annoyance. When it flares up, I simply don’t listen to music. But if it ever becomes a chronic condition, or heaven forbid, a permanent one, I may need to seek a more robust hearing intervention, whatever that might be.

    In the meantime, I’m trying to protect the hearing I have, and I remain grateful for every minute of “normalcy” it still provides.

    1. Last night at the ballet the orchestra sounded just fine to me. Even a mandolin with its quite high pitch. But one ear is rather deaf.
      For me, tone and dynamics rule; these are what makes my music live. To get those it seems one good ear might be enough. Strange but I’ll accept that.
      Ah but what about space acuity? Well I consciously could place a violin and a trombone in left-right space.
      As for depth sensitivity I am not sure if I ever had it, but it never was a feature I recognized or sought. Audio heathen moi? I know Paul would hate losing that sense.

      My recent nerve deafness in one ear only, is of uncertain (Covid?) origin, a severe drop off from 1K

      Recently Hans Beekhuizen’s YouTube pointed out that a large proportion of our music’s energy distribution lies quite low. So that might explain my not missing much. I feel kind of fortunate.
      Oh and the hifi still pleases.

      1. I think you speak to one of the points I hoped to make in these essays – that there are qualities in sound, other than those that diminish with age and disease, that still figure importantly in our perception, and that allow us to enjoy music reproduction just as much (or nearly so) as when we were younger.

        Paul posted a video just a couple of days ago that touched on this topic. The writer was asking about the apparent paradox of having age-diminished hearing by the time he was able to afford truly high-end gear. I’d hoped Paul might mention *Copper* and the articles it has contained on the subject, but alas he did not. 😉

    2. I lost all the hearing in one ear and a significant portion in the other. I still style myself as an audiophile but know I’m missing several abilities audiophiles love or must have, such as directionality, imaging, sound-staging and the like. I wear a bicros hearing aid where sound from the dead side is transmitted to the good side’s hearing aid to simulate binaural hearing. You do the best you can with what you’ve got, right? I still love music and what I’m hearing although I know I am missing so much. Anyone else out there with similar hearing issues? I’d love to know what if anything you do with this disability to maximize listening enjoyment.

      1. That sounds like (sorry) a fascinating device. It’s quite amazing how the brain is capable of adapting to changing stimuli, allowing function to continue, even if in a slightly different form. I also wonder in what ways “single-channel” listening differs when it’s the receptor that’s monophonic (meaning only one functioning ear) as opposed to the transducer (only one speaker, or a pair reproducing an identical signal).

    3. My son is a committed headphone audiophile, and his preferred setup these days is pair of Shure KSE1200 in-ear electrostatic earspeakers. He uses those with a Chord Hugo2 DAC which is, conveniently, the same dimensions as the Shure energizer and is kept strapped to it with Shure’s supplied rubber straps. The sound quality approaches unholy levels of fidelity. He also has a pair of Stax SR009 regular headphones, and he finds he rarely uses them because the added convenience of the Shures in his view more than makes up for the marginal loss of performance. I’ve listened to them myself, and the sound is quite intoxicating.

      Anyway, the whole point of that ramble was to wonder whether a seriously high-quality in-ear headphone is a practical solution for an audiophile suffering the onset of hearing loss? I also wonder whether by combining a set-up like that with a microphone and high-quality DAC might provide a somewhat extreme but high-performance hearing aid … after all, what are audiophiles if not ‘somewhat extreme’?

      1. I think the tail-end of that sound-chain equation is the basis of the best quality in-ear hearing aids, though I doubt even the very best music IEM will ever prove truly effective at offsetting hearing loss, at least not in their standard configurations. There’s the obvious matter of requiring a microphone, which I suspect those devices lack (unless they also happen serve telephone purposes). Then there’s the frequency-based tailoring of the signal that’s needed to make the device’s output complement the hearing the user still has. After all, presenting an audio waveform that’s intended just to mimic reality (even if it does that really well) won’t help offset hearing loss, at least not loss based on frequency. It will just be the same “reality” presented up-close, with the same losses the user hears without the devices.

        Maybe if a true audiophile finds themselves in the ranks of hearing aid design engineers, and can convince the marketing people that an audiophile aid would sell in sufficient numbers, it will happen. Or maybe it already has. In my research I didn’t look at the very high end of the hearing aid market, since those prices are well beyond my reach in the first place.

      Well worth your time.

      An informed optimistic deep explanation that most of the meat of music is where we still can hear, isn’t in the higher frequencies

      1. I’ll look for it, thanks. I enjoy his videos, though the ones I’ve seen often stray into engineering matters that are frankly beyond me.

    5. Craig, a couple more points added to my earlier reply.

      Clean ears — I routinely flush my ears to clean them but just learned I was not doing an adequate job. I wear hearing aids and noticed a recent decline in acuity, so visited my audiologist for an adjustment. She examined my ears and reported significant wax build up. So I again applied a commercial wax softener, then flushed each 6-7 times with warm water. That did not dislodge much. So I continued flushing until close to 20 times (my syringe is small so not much water each time). By then I dislodged as much wax as a kitchen match (wooden) head from each ear! The improvement was immediate.

      Perception of music — From my early 40s I remember listening to a popular jazz recording on a very high quality system. The main memory was distinguishing each cymbal in the drum kit, the tonal differences were clear. Over the years I’ve lost that discrimination. But I still attend live music performances (acoustic as much as possible, but that becomes more difficult; in itself a separate issue) so I still have a perception in listening. But to paraphrase a famous scientist, everything is relative. So when I listen to my system at home I’m hearing that with the same (internal) limitations as in the live music experience (accepting the loss in the recording process). So my point is don’t give up on audio if you still enjoy music, proper hearing aids can help.

      1. Your last comment is so true, and echoes what Frank said in his earlier article, and my restatement of his point in this one.

        Your comment about distinguishing between (or among) cymbals brought to mind the first time I experienced that in a recording (beyond the obvious differences between hi-hats and crash-type instruments). It was from the Eagles’ Desperado album, the song “Outlaw Man.” It’s not a particularly great album in terms of fidelity, even in its most-favored forms (British import LP, 1990’s remaster, or the recent Mo-Fi), but even with the original typically noisy Asylum LP, it’s easy to hear two distinctly different cymbals, one right after the other, on the last note of the measure that features the line “I was born an outlaw’s son.” Henley punctuates the line with two successive crashes, and their tones are markedly different.
