The impact of global acoustic modes on the 8B neutrino flux time series iscomputed for the first time. It is shown that the time fluctuations of the 8Bneutrino flux depend on the amplitude of acoustic eigenfunctions in the regionwhere the 8B neutrino flux is produced: modes with low n (or order) that haveeigenfunctions with a relatively large amplitude in the Sun's core, stronglyaffect the neutrino flux; conversely, modes with high n that haveeigenfunctions with a minimal amplitude in the Sun's core have a very smallimpact on the neutrino flux. It was found that the global modes with a largerimpact on the 8B neutrino flux have a frequency of oscillation in the interval250 \mu Hz to 500 \mu Hz (or a period in the interval 30 minutes to 70minutes), such as the f-modes (n=0) for the low degrees, radial modes of ordern smaller or equal to 3, and the dipole mode of order n=1. Their correspondingneutrino eigenfunctions are very sensitive to the solar inner core and areunaffected by the variability of the external layers of the solar surface. Iftime variability of neutrinos is observed for these modes, it will lead to newways of improving the sound speed profile inversion in the central region ofthe Sun.
