We study the production of gravitational waves from primordial scalar
perturbations in double-inflection-point inflation, in which one of the
inflection points predicts the power spectra consistent with CMB observations
at large scales and the other generates a large peak in the power spectrum of
scalar perturbations at small scales. We find that the reduced gravitational
waves at low frequencies can be detected by future space-based laser
interferometers.
