    A Study of Acoustic Properties of Msterials Used in the Building Industry

  • Original language description

    Článek se zabývá studiem akustické emise tepelně izolačních materiálů typu DEKALIT a DEKALUX. Je zaměřen převážně na jejich odezvu při objemově tepelném namáhání vzorků. Vyhodnocení měření je přednostně zaměřeno na sledování závislosti odezvy (četnosti signálů akustické emise) na teplotním gradientu a na dilatačních změnách vzorků.

    A Study of Acoustic Properties of Msterials Used in the Building Industry

  • Czech description

    A method consisting in the study of a specimen response to a mechanical impulse applied to its surface has been studied. A mechanical pulse generates fundamental and higher frequency harmonic vibrations in the specimen structure. Waves reflected at various inhomegeneities (for example, a base plate on which the specimen is resting, or material structural defects), are superimposed over thus generated elastic waves. The response, being picked up at the surface, carries information on the occurrence of sttructural defects. This information is of integral nature only, providing no details about the defect type, location, shape or size.
