WebAug 14, 2024 · What's the ideal ratio? The ideal ratio is the wrong word to use, there's not one ideal value, but rather an ideal range of ratios. It's like the ideal height, there's not a specific ideal height, there is an ideal range of heights (6'1-6'3). The ideal range of ESratios is 0.45-0.47. Ideal is a synonym for "pleasing to the eye". WebSo the highest frequency that the eye can see is 2 times the lowest frequency can see. Now when it comes to hearing, the highest frequency that can be heard is 20000 hertz and the lowest frequency that can be heard is 20 hertz and the ratio of those frequencies is 1000. So the ears have a much greater range than the eyes in terms of...
