Abstract

An exhaust muffler of a turbomotor, characterized by comprising a device that absorbs by strengthening the sound energies with a frequency greater than 500 hz, constituted by shaped screens lined with porous or fibrous materials, as well as a device attenuating frequencies below 500 hz, constituted by associated resonators, of which each one is adapted to such a frequency, that the set covers all the frequencies below 500 hz, said resonators being established around a bell, whose flanks are perforated and which extends the exhaust pipe of the turbomotor.
