Lowest frequency we can see (4.3 E14 Hz) is the G 40 octaves above the Is between E and F 41 octaves above the E and F above middle C. The highest frequency we can see (7.5 E14 Hz) So the frequency of the C 41 octaves above middle C is 262 * 2^41 =ĥ.8 E14, which is the frequency of green light. We can see light from about 4.3 E14 to 7.5 E14 Hz. Highest frequency of light our eyes can see is not quite twice the Note, because an octave represents a doubling in frequency, and the Terms of musical notes, but there is not a visible color for every The frequencies of light of various colors can indeed be expressed in I have no idea what researchers would chargeįor this information but here's at least another $25.00 for your work. It! racecar provided the foundation and you provided the map toĮxpand on this issue. Hedgie-ga, Thanks for the clarification and your brain on this. To racecar.ga your thoughts and complete breakdown of the notes andĬolors is an exceptional resource for me in my field. Simple function, then racecar's mapping is without a fault. ![]() If you are satisfied with a subset of colors and subset of tones and There are colors which are not pure,īut which we do see as different from pure colors (e.g. I considered more general mapping: Mapping of all sounds we can hear toĪll colour shich we can differentiate. Racecar considers only pure (spectral) colors and tones. Th eother difference between Racecar's answer and mine is in this: For younger people it isĢ0Hz to 20kHz, which is more then the segment which racecar picked. ![]() To whole audible range as I suggested, or use just part of the range,Īudible range changes a bit with age. You also may choose if you want to map whole visible range Linear function (roughly, racecar's choice) Unless you provide additional requirements, (color and pitch), which racecar sketched can be, and should be, describedīy a mathematical function. However, I will answer your CRFs as needed. Commenters (racecar, ofer) do not have this As GA researcher I cannot communicate with you directly I usually come back to read the comments, but it is not required or If you are not happy, please do ask for clarification. To improve my skills if I know how well,or how badly, I did answer. If you are happy with the answer, please do rate it. Pure tone (single line a spectrum) would then correspond to a pure color,Īnd 'white noise' would map on white color.(zero saturation) Purity (spectral with) would be a good match for SATURATION. Since intensity naturally corresponds to volume, you must select twoĬharacteristics of the sound spectrum to map on the other two dimensions of light.ĭominant tone (main peal in the spectrum) would be a good match to HUE. Inner ear has many more sensors, and sound perception has more dimension. Types of cones and so has three dimensions. (a graph which how much energy is in each frequency band). Physics represents sound and light in a similar way, by a spectrum Which has additional explanation on human perception of color. ![]() May be better to reserve saturation for another property of sound. Since duration of the tone may mapped on the duration of flash, it You may choose duration of a note, or something like timbre. Pure (rainbow) color has no obvious analog. Saturation,which increase as we are going from white to pastels to Hue would match the dominant tone (pitch) of sound (low or base) Luminance describes to intensity of light (volume of the sound) There are different transformations of those three Ī simple set is this: hue saturation and luminance. Person to person, once we exclude colorblind subjects). The numbers (coordinates or coefficients) differ vsry slightly from ![]() We can clarify it as much as needed, on request.įor starters: each perceived color can be described by three number Somewhat technical explanation of chromatic coefficients is given here Interesting question: Mapping sound to colorĬomment below has some merit, but I am going to offerĭifferent mapping, mapping based on human perception Understand what I'm trying to do, see my website at Joia1 Match these up by science as apposed to art. Transposing that up by octaves into the light spectrum can the colorīe determined? For example, C = Red D = Orange, etc. By looking at the frequency of a note, ie. I make musical instruments and would like to correlate musical notes
