Rot flaw detection used for that purpose is represented by invasive and non-invasive devices. Non-invasive devices are very accurate, but due to the cost and complicated operation they have not been applied on a large scale in forest management. Taking into account the practical needs of foresters a prototype of low-frequency flaw was developed. The principle of its operation is based on the difference in acoustic wave propagation in sound wood and wood with rot.}, type={artykuł}, title={Internal rot detection with the use of low-frequency flaw detector = Wykrywanie murszu wewnętrznego za pomocą defektoskopu niskoczęstotliwościowego}, keywords={drewno zmurszałe, defektoskopia murszowa, gospodarstwa leśne, defektoskop niskoczęstotliwościowy, internal rot, flaw detection methods, forest holdings}, }
