Strain Voice Test DIVAS

During a voice strain test, the test person reads a text with varying loudness targets. The sound pressure level (SPL) and the fundamental frequency are measured in real-time. To ensure self-monitoring and motivation, the test person receives feedback during the test; changing screen colours indicate when the voice exceeds upper or lower target levels. The strain levels, test duration and speaking volume can be freely configured.
