"Noise of building services is one of the undesired factors of environmental conditions. Especially noise of boilers, that is generated into the outside of boiler-rooms trough smoke pipes and chimney, is very often higher than hygienic limits. Report is concerned with a resonance problem in boilers, smoke pipes and chimney and its interaction for acoustic spectrum generated by chimney. It is discussed subsidiary flu system combustion oscillation mainly in very low frequencies range. On a few examples are shown possibilities of reduction of infrasound."@en . "80-02-01403-0" .
