What do we hear when we change the direction of a wire?
I wouldn’t be lumping Bekesy in this argument as agreeing with Essien. Békésy cannot agree with a future writer after his death... But he was one of those who prove that there is more than Fourrier analysis to hearing.... His Nobel prize is linked to that.... Are you an authority in acoustic now? Did you read Essien? if so, what does he speak about? 😁😊 BéKÉSY : The Missing Fundamental and Periodicity Detection in Hearing 1972 |
Then why BÉKÉSY feel the urge to denounciate this reduction exactly 50 years ago ? He did not even denounce Ohm, he said it was always obvious Ohm was not the be all and end all. Seebeck showed that 170 years ago. Bekesy was not "denouncing" , he was just making a statement. How about we move the discussion into the 20th century. https://neuro.wisc.edu/wp-content/uploads/sites/131/2020/12/PDF1.pdf From Wikipedia, essentially why he got the Nobel, "Békésy concluded from these observations that by exciting different locations on the basilar membrane different sound wave frequencies excite different nerve fibers that lead from the cochlea to the brain. He theorized that, due to its placement along the cochlea, each sensory cell (hair cell) responds maximally to a specific frequency of sound (the so-called tonotopy). Békésy later developed a mechanical model of the cochlea, which confirmed the concept of frequency dispersion by the basilar membrane in the mammalian cochlea." You will note nothing in there about what happens after ear, and how far we have progress when you look at the article I linked. |
How about we move the discussion into the 20th century.Thanks for the link..... 😁😊 i already own the masterbook of acoustic tough.... But this is shorter read... «Pitch is a subjective term. It is chiefly a function of frequency, but it is not linearly related to it. Because pitch is somewhat different from frequency, it requires another subjective unit, the mel. Frequency is a physical term measured in hertz. Although a soft 1-kHz signal is still 1 kHz if you increase its level, the pitch of a sound may depend on sound-pressure level. A reference pitch of 1,000 mels is defined as the pitch of a 1-kHz tone with a sound-pressure level of 60 dB.» Master handbook of acoustic p.85 Nothing i read made Essien nor Ansermet ridiculous by the way....Nor obsolete at all like you affirm.... But it is only the begininng of my reading..... By the way my mechanical equalizer distribution and location of tubes and tunable pipes use the loudness level of each of my speaker in a different way to make my 2 ears able to recreate a 3-d holographic soundstage by working with better timing between reflecting and direct waves.... I get the idea arguing with you.... Then who knows ! you will give me an another one.... anyway thanks.... |
For sure pitch is not reducible to frequencies .... But It is what you affirm to me erroneously in one of your post ... Pitch is by definition reducible to frequencies. Pitch is a definition. That does not mean we can't fool the brain, or distort the auditory system to create a perception of a pitch that does not match the true frequency components. But that is like trying to argue an optical illusion is the real result, not what is actually in the underlying image. |
