...higher, makes 1600 vibrations in the same time. It appears, by experiment, that we cannot determine the sound of a string which makes less than 30 vibrations in a second, because it is too low, nor of one which makes more than 7552 vibrations in a second, because too high. These limits determine... | |

...regular intervals, and are completed in a second. It appears by experiment, that we cannot determine the sound of a string which makes less than 30 vibrations in a second, because it is too low, nor of one which makes inore than 7552 vibrations in a second, bocauso too high.

In Euler's Letters, vol. i, p. 14, of the English translation, it is said — " It would appear that we are incapable of determining...vibrations in a second, because it is too low, or else of a string which makes more than 7,552 in a second, because it is too high ;" and in Schoedler's... | |
