The present invention relates to a fibre comprising a profile of at least one synthetic material. The invention further relates to a woven fabric or a mat comprising such a synthetic fibre. In addition, the invention relates to a nozzle for manufacturing such synthetic fibres. The invention also relates to a method for manufacturing such synthetic fibres, as well as the use of the synthetic fibres. The profile of the fibre according to the invention comprises at least one chamber. The surface area of the cross-section of a fibre is on the one hand hereby enlarged, wherein more sound energy is absorbed, and in addition chambers are formed which result in a damping of the sound. The nozzle is a plate with recesses and is characterized by a recess which defines at least one chamber. |
