I do have a question for you. I have what I believe to be an ammonite, first discovered by me between 1973 and 1975 in Germany while on field maneuvers in a U.S. military training area. It’s a circular spiraling shape about 5” in diameter and about 1” thick. It’s mostly light orange in color, though other parts of it are darker and look like pieces of shell. It is still intact exactly as I found it… never brushed, never cleaned, or exposed to water, etc. I would really appreciate your help in identifying what it really is, and approximately how old it might be. Thank you in advance… I can also send you pics of it if you like.

You really need to enlist the help of your colleagues who are familiar with the fields of acoustics and psychoacoustics as there are numerous errors in this video. An example is the cochlea, and referring to it as a "4000 frequency spectrum analyzer." It doesn't work quite like that as the basilar membrane's vibrations are what stimulates the cells, and both the membrane and cells have finite dimensions. As such, the resolution declines with rising frequency as each span of the membrane will respond to a progressively broader and broader range of frequencies. At low frequencies, the resolution is quite good, but becomes progressively poor as the frequency rises and this is why we have octaves in music, to reflect the fact that we perceive the scale of frequency logarithmically. Additionally, while a dynamic range of "120 dB" is quoted, with complex things such as music, the situation is considerably more nuanced as there are things such as masking and critical bands to consider that limit our ability to discern separate components in sounds we hear. While we can easily hear noise down around 0 dB absolute, we struggle to hear distortion products that are more than 35-40 dB below the threshold of the music we listen to as they are competing with the source material itself, and often fall within the masking range of the main spectral content. Also the notion of it being a spectrum analyzer is fine from a conceptual point of view, but the actual way we resolve sound is considerably more complex and nuanced.
@sub-harmonik Жыл бұрын
the frequency resolution of the membrane declining with higher frequency wouldn't be that relevant, nor would it necessarily contradict '4000 frequency spectrum analyzer'. Also he's speaking generally, obviously he's not going into specifics on that one topic. (especially when the topic is time-domain perception, not frequency domain perception). Similarly he's not going to go into detail about the '120 db' thing and both of these things are odd things to nitpick about in the video. I will say that him saying the piano samples have the same spectrum is an odd way to make the point, but that's more a matter of miscommunication. And I'm not sure why you think he would disagree with 'the actual way we resolve sound is considerably more complex and nuanced' because that was his entire point, and he even had a slide dedicated to it.
@mysock351C Жыл бұрын
@@sub-harmonik As an example, the "120 dB thing" is not a minor point, nor a nitpick. This stems from a misunderstanding of someone using 120 dB, the highest level sound that can be heard before true pain sets in, as the upper limit for the ears dynamic range, with 0 dB, the threshold of hearing, as the low range. This is completely wrong, and not how we hear. Due to effects such as masking and ERB, the actual dynamic range of the ear is about 35 dB in normal listening, and about 45 dB in critical listening situations. Anything that is below the main audio by about 50 dB is no longer able to be perceived, and this seems to hold fairly universally for people who have had a look. And even those figures are being quite generous. This is one reason why people find LPs, which can barely eek out 25 dB of dynamic range, acceptable. The only time this is violated is when the two sounds are very far apart, such as a low and a high frequency tone playing together. However, for spectrally complex things the above seems to hold, and I have yet to really see any contradictions to that. Its certainly not 120 dB, even with respect to noise when no sound is playing. That is probably about 90 dB in practice. I was being quite magnanimous with my comments. The truth is from reading his papers, he is a clear charlatan who either knows nothing, or is deliberately ignorant of how audio and psychoacoustics work.
