Abstract [en]

High vocal demands and speaking in environmental noise have both been identified as risk factors for voice disorders. Long-term field documentation of voice use might provide important information on those factors. The purpose was to explore how long representative measurements need to be, and whether long-term data from the field can usefully supplement voice assessments made in the laboratory. Eight patients diagnosed with occupational voice disorders were chosen consecutively from a waiting list for voice therapy at the Karolinska University Hospital. They were matched to vocally healthy colleagues regarding gender, occupation and work place. The sixteen participants underwent a series of voice assessments in the laboratory: audio recording, voice range profile, laryngostroboscopy, and subjective evaluations using the Voice Handicap Index. A long-term registration during 14 days was performed for each participant using the portable voice accumulator VoxLog. Voxlog has a neck collar with an accelerometer measuring fundamental frequency and phonation time, and a microphone measuring the level of voice intensity and of environmental noise.  The participants wore the Voxlog from morning to night for two full weeks.  They kept a diary of daily activities and rated voice symptoms four times daily. Preliminary results show that data obtained from the first week were similar to data from the second week; and that fundamental frequency and voice intensity were higher in the field than in the laboratory. The results provide a basis for discussion about valid voice outcome measures.
