...two vibrating forks thus supporting each other will produce a sound of greater intensity than that tj either of them vibrating alone. It is, however, also easy to see that the two forks may be so relited w each other that one of them shall require a «*• densation at the place where the other... | |

If this be the case the two forks will assist each other. The condensations will, in fact, become more condensed, the rarefactions more rarefied, and as it is upon the difference of density between the condensations and rarefactions that loudness depends,...
