The full characterization of the sound field in a room from experimental data is a challenging problem, as the direct measurement of the sound field in the volume requires considerable experimental effort. In this study, the sound field in a room at low frequencies is characterized using a representation in wavenumber domain that infers the modal structure of the sound field. The modal structure is used to synthesize frequency response functions, to characterize the spatio-temporal properties of the wave field. The proposed method makes it possible to infer frequency response functions between source-receiver pairs that have not been measured, exploiting the representation of the sound field as a modal superposition, and thus reducing the dimensionality of the reconstruction problem
