Which brings up an interesting point. The level of this horizontal oscillator frequency reaching our ears is certainly WAY below established OSHA and others hearing loss warning levels. But I spent many years on a service bench working on old school TV sets; high school and college years both. I also worked on stereo sets; mostly using headphones for amplifiers, receivers, etc. We had a very large shop; over 20 inside technicians and over 20 outside technicians. Could this exposure have contributed to my upper frequency loss even though that was over 40 years ago? My Dad had more severe loss; couldn't hear about 5 KHz from age 50 and up; some of this is certainly in the DNA and genes I'm guessing. I went to 50+ rock concerts back in the day; this also would have contributed; I worked on ships, in ship yards, etc...Didn't always have in ear plugs or wear ear muffs. I never was around guns much but many of my hunting buddies never wore hearing protection...there ya go!...
Can a one-eyed person get a driver's licence? Can a one-eared person make reasonable judgments about their auditory environment?
Both for vision and hearing, there are lots of real-world cues to the perception of location, not just the sort of cues beloved by those inclined to Faith in Engineering.
Footnote: if you bring people into a dark lab and test them using tones on loudspeakers at different distances.... the only cues available are the "usual suspects". That's OK for certain research purposes. But that's not a good simulation of hearing "in the wild".

About front back location: This morning I was doing an Otis Reading - sitting on the dock of the bay, watching the tide roll away. I was using in-ear mics to record the gentle sounds of the waves, the flies buzzing, the jet flying over. Then I heard a bicycle approaching from behind, two girls chatting quietly. I just let the recording roll, wondering how it would sound.
Listening to the recording on headphones, they are distinctly behind me. Of course it was recorded with my head and my ears, so not sure it would work for anyone else. But for me it works.

I'm sure he saw the world in glorious 3D depth. He just didn't have the cue of stereopsis.... which left a dozen other cues (for example, what might be called geometric perspective).
Ditto for concert goers with hearing in just one-ear. If you have a hearing aid in one ear and are watching TV, do the voices seem to come from the corner of the room or from the TV or speakers?

Not sure about the glorious 3D depth, but yes to the other things. For a very good exploration of this, read:

Pano,
I bought a Sennheiser MKE 2002 binaural mic with dummy head back around 1990. While listening to the output of the binaural mic through headphones, the illusion of the sound presented as behind behind my head, when the dummy head (which has ear pinna) was turned away from the sound source was enough to make me "believe my ears" rather than my eyes.
For example, rotating the dummy head while someone was talking in front of me would make me believe I had turned my back to the speaker, even though my eyes could see that clearly did not happen.
Thirty years later, with my high frequency hearing subsiding, and 4kHz noise induced hearing loss, the "behind the head" imaging is pretty well non-existent.

What I am going to write cannot be proven or even corroborated. It is an opinion in its complete sense.
I have the persuation that human consciousness adjusts for degrading sensory stimuli, which would imply, human perception in the old is automatically corrected by the mind. This conviction arises from the fact, that till now, age 53, I am not noticing any auditory differences while I listen to music tracks I used to listen to when I was still a youth and a young adult.
Doing a youtube hearing test I must have severe hearing loss in the bass and sub-bass regions. However, I can still perceive and hear bass: my listening experience is not limited to midrange and treble only.

The NIHL (noise induced hearing loss) at 4kHz was pretty specific to that 1/3 octave range, "3D" hearing above and behind was OK when I still had decent hearing to 15kHz.
Now that the upper frequency response is going down the ski hill, there is little range for the pinna to determine vertical and rear direction location with, since most of the pinna related binaural localization occurs above 4kHz.

That is probably because your high frequency hearing loss is not so bad. A friend of mine who is a drummer is very aware that he cannot hear higher frequency content in recordings anymore that he is familiar with.

I failed the test apparently because it came up with two results, 5kHz and 10kHz, was that really a failure?

A recent listening experience pointed out to me that I do hear differences in music tracks I listened to 50 years ago.
As a youth, I spent far too much time listening to the Webber/Rice musical Jesus Christ Superstar (1970). I knew the album by heart. Haven't really listened to it since 1975
This past weekend I dug out the 2 LP set and had a listen. 45-50 years ago I thought some of the edits on the soundtrack were somewhat crude, or brusk, but just figured that's how it was. But now all these years on I have to say the whole soundtrack is just downright odd. I'm not talking about the music, but the production. Edits are clumsy, each song and each singer sound like they were recorded separately and pasted together by a first year intern. Many of the recording, mixing and mastering choices are strange and don't flow.
In the early 70s I had not done much recording and editing work, so the faults were only just noticeable to me. 50 years later and a lot of work under my belt, the faults jump right out. Despite some hearing loss, I'd say my hearing has gotten better. It's gotten better because it's had a half a century of practice. If I live another 50 years, maybe I'll be able to hear exactly what drugs they were doing n 1970.
