Vocal strain deficits are not yet standardised quantified. The investigation of vocal parameters in real professional requirements is still in experimental stage. Simulating these requirements in a shorter time with higher sound pressure levels is already possible by using a computer aided test.
28 patients with voice disorders and 12 subjects without voice complaints attended a computer-aided voice strain test (reading a text 15 min, five minutes at 70 dB (A), 75 dB (A) and 70 dB (A); software and hardware: DiVAS, XION, Berlin). Before and after test they completed self assessment questionnaires and passed through an acoustic voice analysis.
The presented voice strain test gives hints of reduced vocal load capacity in everyday life. The test was assessed by all participants, patients and volunteers, as "strenuous". For the analysis, the results will be graphically illustrated and documented.
Due to the consistency of the anamnestic data with the results of the voice strain test, we assume that with the new voice strain test a total lack of voice resilience can be identified and documented by using a higher short-term vocal loading and analysing the effects on vocal sound and mood.
