An acoustic panel () includes a plate () made of an acoustic absorbing material (), as well as a resistive skin () and a backing skin () arranged respectively on both sides of the plate (), the acoustic panel () including acoustic elements () able to carry out an acoustic absorption, each of them being arranged in a housing () provided in the plate () with an opening () in front of the resistive skin (). The combination of the plate () and the acoustic elements () allows to combine the sound attenuation properties of these two types of elements and to increase the frequency range of sounds that can be attenuated by the acoustic panel (), without increasing the dimension.
