The invention relates to an air intake lip (2a) of an aircraft turbomachine nacelle extending along an axis X, in which an air flow circulates from upstream to downstream, the lip (2a) extending annularly about the X-axis and having an inner wall (21) facing the X-axis and an outer wall (22) which is opposite the inner wall (21), the inner wall (21) and the outer wall (22) being connected by an upstream wall (23) so as to delimit an annular cavity (20), the lip (2a) comprising an annular acoustic device (50) mounted in the annular cavity (20). The lip (2a) has a first module (M1), comprising the outer wall (22), the wall (23) and a front wall (24) forming an upstream portion of the inner wall (21), and a second module (M2), comprising the acoustic device (50) and a front skin (51) forming a downstream portion of the inner wall (21), the first module (M1) and the second module (M2) being secured together so that the front wall (24) and the front skin (51) together form the inner wall (21) of the lip (2a).
