 ... instantly restored. Or the balance, on which silence depends, may be upset by connecting the ear with a tube, whose other end lies close to the mouth of one of the pipes. By means of beats two notes may be tuned to unison with great exactness. The...  A Text book of physiology v.4, 1896 - Page 224by Sir Michael Foster - 1891Full view - About this book

...meet so rise to beats? as alternately to intensify and destroy each other, and give rise to " beats." The number of beats in a second is equal to the difference in the numbers of vibrations made by the sounding bodies in that time. Thus, when two tuning-forks,... | |

...the 42d of the other; the condensations coincide five times, or there are five beats, each second. The number of beats in a second is equal to the difference in the number of vibrations which the two sounds make per second. Beats can be made much better than... | |

The number of these beats per second is equal to the difference between the number of vibrations per second of the signal current and of the local current, and this difference is converted into sound which is perceived... | |
