Nowadays combinations of textile materials are common solutions in acoustics aplications as absorbent acoustic materials. Researches developed previously make possible to assert that the nanofibers textile veils combined with the textile wools, will improve the acoustic proprieties of the latter. These kind of nanofibers textile veils are made with a process known as electrospinning process Furthermore, these kinds of combinations present an airflow resistivity value within the range established by the Technical Edification Code in Spain, so that, we can use these kinds of materials in sound insulation applications to reduce sound waves confined between two walls in a multi partition or in many other applications such as noise reduction in air conditioning systems or in the design of the electroacoustic systems In this work we have studied the application of nanofibers as a cover of the polyester wools which are placed under drilled panels. We can assert that an increase of just 1% of the absorbent material thickness with a nanofibers veils, is enough to improve the acoustic absorption at low frequencies, in the cases submitted. |
