If one adds a (pseudo-) magnetic field to a system involving Weyl points, the Weyl points split into the so-called chiral Landau levels, among which the zeroth chiral Landau level has linear band dispersion. This paper reports an experimental realization of the zeroth chiral Landau level using an acoustic metamaterial in a synthetic dimension.
