Photometric (ubvy-β) and spectroscopic observations of the δ Scuti variables 7 Aql and 8 Aql are described. The Strömgren standard indices and physical parameters of both stars are derived. Spectral types of F0V and F2III have been assigned to 7 Aql and 8 Aql respectively considering the results from both spectroscopy and photometry. Differential uvby light curves were also analyzed. A attempt of multicolour mode identification is carried out.
