The invention relates to an air intake lip of an aircraft turbomachine nacelle extending along an axis X, in which an air flow circulates from upstream to downstream, the lip extending annularly about the X-axis and having an inner wall facing the X-axis and an outer wall which is opposite the inner wall, the inner wall and the outer wall being connected by an upstream wall so as to delimit an annular cavity, the lip comprising an annular acoustic device mounted in the annular cavity. The lip has a first module, comprising the outer wall, the wall and a front wall forming an upstream portion of the inner wall, and a second module, comprising the acoustic device and a front skin forming a downstream portion of the inner wall, the first module and the second module being secured together so that the front wall and the front skin together form the inner wall of the lip.
