    摘要： A noise suppression device (1) includes a noise suppression unit (11) to generate post-noise suppression data (Ss(t)) by performing a noise suppression process on input data (Si(t)), a weighting coefficient calculation unit (12) to determine a weighting coefficient (α) based on the input data (Si(t)) in a predetermined section (E) in a time series and the post-noise suppression data (Ss(t)) in the predetermined section (E), and a weighted sum unit (13) to generate output data (So(t)) by performing weighted addition on the input data (Si(t)) and the post-noise suppression data (Ss(t)) by using values based on the weighting coefficient (α) as weights.
