Meta-analysis of acoustic-induced mechanotransduction in agricultural crops
Inverse-variance meta-analysis of seven studies reports a weighted mean yield increase of 18.64% (95% CI 11.91-25.36%) under 200-2000 Hz acoustic stimulation, with six high/moderate-severity methodological caveats including geographic concentration and small-sample bias.
