EN Widely available and inexpensive biomedical devices for domiciliary use may emit noise. Nebulizers are one of them. They allow taking drugs in the form of vapours thanks to vaporization under reduced pressure using an ejector (vacuum generator). The sources of noise in a nebulizer are an air compressor and a vaporizing tip. The presence of two sources with a different noise character and unfixed spatial orientation allows to classify a nebulizer as a device with extensive sound sources (DESS). The article presents the results of acoustic measurements of the nebulizer and its components. Differences in the nature of components’ noise were found and their estimates were compared. Noise hazards for the device’s user were determined and the premises for the noise parameterization of devices of this type were specified.
