Abstract Objective The effects of sound treatments on the germination of maize seeds were determined.Results White noise and bass sounds (300 Hz) had a positive effect on the germination rate.Only 3 h treatment produced an increase of about 8%, and 5 h increased germination in about 10%.Fast-green staining yale law school colors shows that at least part of the effects of sound are due to a physical alteration in the integrity of the pericarp, increasing the porosity of the pericarp and facilitating oxygen availability here and water and oxygen uptake.Accordingly, by removing the pericarp from the seeds the positive effect of the sound on the germination disappeared.
