Acoustic de Haas-van Alphen effect of a semi-metallic compound LaAs has been investigated. The electron α Fermi surfaces and the hole β, γ surfaces in LaAs have been observed. The carrier number of LaAs was n = 0.0024 per La atom. The oscillation intensity of the longitudinal C11 mode revealed enhanced values |gii| ≊ 8-16 of the electron-strain coupling constant α and β surfaces in LaAs.
