Measurement of noise produced by sources close to an ear – on the example of headsets

Summary/Abstract: The article presents the results of measurements of noise parameters generated by headsets. The results of direct measurement carried out using an acoustic manikin were corrected so that the obtained values corresponded to the free-field conditions and could be referred to the criterion values of noise exposure assessment in Poland. In case of A-weighted equivalent sound pressure level, the correction value was determined according to the normalized method. However, in case of A-weighted maximum sound pressure level and C-weighted peak sound pressure level the own method of determination of this correction was proposed. The results of measurements presented in the paper showed that for the tested headsets, at the specific settings of gain level, no exceedance of the noise exposure limit values occurred. However, it is possible that the action value may be exceeded for daily noise exposure level. Moreover, the measurements showed that the correction values for the A-weighted equivalent sound pressure level, A-weighted maximum sound pressure level and C-weighted peak sound pressure, regardless of the method of their determination, are similar to each other. However, the correction values depend on the headset, which was used to play the test signal.
