Abstract

A large part of the environment is made up of soundwaves. Infrasound, audible sound, and ultrasound are the three most sommonly found in nature. Even though these soundwaves are a key part of the environment, they have been neglected in research when it comes to their relationship with organisms. This study found the correlation between soundwaves and siingle-celled organisms. It was hypothesized that when two specific soundwave frequencies were played regularly during the Physarum polycephalum's life cycle, the higher of the two frequencies would have a higher growth rate. Thirty of these protists were tested, one set of ten with a high frequency, one set of ten witha low frequency, and one set of ten with no frequency. A one way ANOVA was run, and the conclusions of thistest showed that the high frequency's growth rate was faster. However, the overall objective of this study was to find if the frequencies grew faster compared to the regular growth pattern of the Physarum Polycephalum. The raw data and ANOVA results showed that the frequencies do grow at a faster rate.
