You should design to what is important to the ear not the oscilloscope. When you understand what is important to the ear you understand what to look for on your instruments.

It's interesting that the earth was not flat but armies lined up into ranks and just shot at eachother well into the 1860's.

Given the accuracy of those crooked shooting irons issued to soldiers at the time the tactics made sense.

However, even after proven outdated in the war between the Confederation and the Union they where also carried on into the age of the machine gun and precision field artillery by Generals so inflexible, they could not see how much the world had changed in 50 years.

The results where the appalling casualties of the first world war on all sides.

It is comforting to know that if people close their minds in Audio, the worst that happens is bad sound, not tens of thousands killed in one day.

But the underlying mindsets and failures are sadly of the same nature.

50 Years after THD has been shown useless we still measure THD.

Meanwhile other things that we know to matter are being ignored for as long.

Sure archers did not, nor did musketeers shoot just straight, even in those days the sights had elevation build in.

Based on the results of Georg von Békésy, Experiments in Hearing. McGraw Hill. p.335, 1960



And it has 30% 2nd Had for 94dB of 200Hz tones.

There is actually a lot more in this research.

Ciao T

Thorsten,

As far as I know Von Békésy examined the movement of the cochlear partition in human and animal cadavers. Through observation of silver particles scattered on Reissner's membrane, he presumed that this was similar to the movement of the basilar membrane.

So, what he was basically doing is looking at the mechanics of the inner ear, after preparation of samples. I don't dispute that this provided some new insights, such as the travelling waves in the cochlea, but it is research that took place over 50 years ago, and his findings have been questioned since, at least to some extent.

However, and this is not a detail, Von Békésy's research applied to prepared basilar membranes, and the ear is an active pick-up system. The basilar membrane shows considerably less frequency selectivity than either the inner hair cells or the single fibres of the auditory nerve.

In other words, even if Von B. found harmonics on the basilar membrane, it would be a stretch to translate this one on one to what comes out of an ear in vivo, as measured on the auditory nerve.

Considerable additional research backs the conclusions. Including work on distortion perception from Olson via D.E.L. Shorter to Geddes et all.

Of course, one may reject evidence contrary to ones beliefs, should one be so inclined....
