Effect of three types of sound frequencies falling within the audible range (20 Hz- 20 KHz), on bacterial growth and the antibiotic susceptibility was investigated. The bacteria used as the test organism (E. coli) was found to register better (17.5- 25.67%) growth at a frequency below 1 KHz (432 Hz), but surprisingly were witnessed to register an extremely poor (83.45-86.72%) growth at a frequency above 1 KHz (4 KHz) under the influence of distinctive sound frequencies. Sound treatment was also found to affect the antibiotic susceptibility, as our test organism was shown to exhibit a greater (11.14-13.23%) antibiotic susceptibility under the influence of a frequency below 1 KHz (432 Hz), but again was shown to exhibit a lower (5.67-6.23%) antibiotic susceptibility under the influence of a frequency above 1 KHz (4 KHz). Intracellular concentration of cations (calcium and potassium) and protein content of the music treated cultures was also significantly different than the untreated control. The audible sound employed in this study was able to affect growth and antibiotic susceptibility of our test organism.
