Do your plants talk back? They will if you listen closely.
Experiments have been conducted on a plant's ability to communicate and the response of plants to Human interaction. These experiments have been performed by a variety of scientists worldwide as well as by 'lay people' like the Mythbusters. It has been proven again and again that plants will respond to certain types of noise better than others. Is it the actual noise or is it the vibrations created by the noise to which the plants respond?
Scientists in China discovered that crop plants will increase their yield when sound waves of certain frequencies are broadcast to them. The frequency levels at which plants respond are well out of the range of human hearing.
Plants also communicate among themselves, usually by scent. This has been proven again and again. But do they 'talk' to each other? In some sort of way that resembles human conversation? Maybe. A team of researchers are currently studying if some plants have specific requirements for sound and if some plants are more talkative than others.
