Abstract [en]

Use of noise dosimeter recordings in low sound level environments is often problematic due to the voicecontribution from the carrier. The aim of the study was to find a microphone position with low speechcontribution while still providing an accurate sound level recording. An experiment with differentmicrophone positions was conducted in a low sound reverberation room. Two types of noise dosimeterswere used (Brüel & Kjaer 4445 and Larson Davis Spark 706-Atex). In repeated measurements the carrierwas instructed to read a text chapter during 60 seconds and at a speech of level about 60 dB(A), acquiredby practice, with different background noise and noise levels. White noise and preschool noise was usedat sound levels 50, 60, 70 and 80 dB(A). The voice contribution to the background noise level was thenmeasured. Three microphone positions were tested; on the shoulder, above the ear and on the back of thehead. The position with the microphone placed behind the head of the carrier had the lowest speechcontribution, less than 2 dB(A) to the background noise at 70 dB(A). This compared to positions rightabove the ear 6 dB(A and on the shoulder 12 dB(A).
