Understanding Sample Rate

 Bone conduction is one of the reported mechanisms for noticing HF above the normal hearing range.

 

Honest question: Can you say with any certainty that "bone conduction" contributes (or not) to your musical listening?

I have no way of knowing.

I do however know that there are specialised hearing aids designed around bone conduction.

 

Thanks.  I was just curious if you were claiming to have ultrasonic hearing.

I believe yes. My youngest are twins born premature, very. I spent 16 years of speech therapy with my son because he is neurologically deaf between about 3 and 8Khz, how they confirmed this was by doing bone conduction tests (I believe it bypasses the ear canal). But like all hearing its just another way the pressure waves are transmitted to the ear, the same rules of hearing still apply, 20-20. It's the same reason your voice sounds alien when played back from a recording and how you can have totally silent headphone (bonephones).

 

I appreciate your insight.  I was more interested in testimony of audio bone conduction as part of the audiophile experience, not so much for proof that audio bone conduction exists.

Regarding sampling rate, there was a time when I was fully on board with the notion that 44.1kHz was simply outdated and a reflection of consumer electronics processing power and data capacity of the era of CDs.

 

But I've gained a newfound respect for good old Redbook over the last 3 years or so.  Not saying higher rates and bit depths don't have merit depending on where/when they're used, but I am saying I could live with Redbook only if I had to.

I can tell you that after meeting a few mastering engineers at a few electronics shows, 24 bit, 44.1 kHz is considered the new standard output for most new releases, across all genres, including classical. Anything over is seen as unnecessary.

 

Btw, I am just passing what I heard, I don't know. But I am slowly coming around to your way of thinking.

 

In my experience using a DAW, dithering from 32 to 24 bits results in little quantization noise.  32 to 16 results in much more, which is why I assume that 24/44.1 would be a preferred mezzanine format.

Honestly, I kind of wish 44.1kHz filters would just cut off at 19kHz instead of 20 (or higher) - would give them more room to do their work, and no one over the age of about 20 would be able to hear the difference anyway. 

On a DAW, you can easily change the filter steepness and cutoff shift to achieve this and more:
