Acoustic Evaluation of Struto Nonwovens And Their Relationship with Thermal Properties

Popis výsledku v původním jazyce

This paper presents an experimental investigation on the sound absorption behavior and thermal properties of Strutononwovens by establishing relationship between these properties. Seven Struto nonwoven fabrics were selected toexamine the noise reduction coefficient (NRC) and average values of sound absorption coefficients as well as thermalproperties, including thermal conductivity and thermal resistance. The Bruel and Kjar impedance tube instrument andAlambeta were used for the evaluation of acoustic and thermal properties, respectively. The influence of structuralparameters on acoustic and thermal properties of Struto nonwovens were investigated and analyzed. The results showedthat Struto nonwovens with higher thickness, finer fibers and higher fabric grams per square meter can provide bettersound absorption performance. The effect of specific airflow resistance on sound absorption performance was alsoinvestigated. It is observed that sound absorption performance has a strong correlation with specific airflow resistance.The effect of porosity on specific airflow resistance and thermal properties was studied in detail. The result indicated thatporosity has a strong correlation with specific airflow resistance and thermal properties. It was also observed that soundabsorption, the NRC and have an insignificant correlation with thermal conductivity, while they are strongly correlatedwith thermal resistance. The correlation coefficient of the NRC with thermal resistance is 0.9835, indicating that theNRC is directly proportional to the thermal resistance of Struto nonwovens.
