Hi,
"The noise annoyance level of participants was determined by a questionnaire (ISO, TS 15666) after saliva sampling in the afternoon. Annoyance level was determined by two numerical questions with a scale of 1 to 11 and verbal questions with a scale from no-annoyance to high degree of annoyance."
Thanks!
