Effect of Sound on Yeast

"It is undeniable that music and sounds can strongly affect our emotions and mood, but so far the study of physical stimuli provoked by sound waves on living organisms has been mostly focused on brain and sensorimotor structures of animals rather than basal cell metabolism.

Using metabolomics and shake-flask cultivations under identical growth conditions, we have compared the physiology of Saccharomyces cerevisiae cells growing in the presence of music, high frequency and low frequency sound waves and cells grown in the silence. All sound stimuli tested not only increased significantly the growth rate of yeast cells but they also reduced biomass yields."
