Abstrakt
In spite of the fact that standardizing operations and increased awareness
of hazards led to a significant improvement of vibroacoustic climate of
operator’s stands of new machines, their long-term operation - often under
difficult conditions - leads to a fast degradation of acoustic qualities
of machines. Temporary operations performed during surveys and periodical
overhauls are rarely effective, due to the lack of any guidelines. In this
situation the authors propose the algorithm for selection of eventual
screens or sound absorbing and sound insulating partitions, utilizing the
measuring procedure aimed at identification, at the operator’s stand, of
main noise components originated from various sources. On the basis of
this procedure, the vibroacoustic energy propagation paths in the machine
was estimated.
