Proposed reference for METF measurements. The reference range is calculated as the 2-sided 95% tolerance interval. Upper: stapes footplate displacement in dB ref µm/Pa. Lower: stapes footplate velocity in dB ref µm/s/Pa. Inferential statistics from 366 METF measurements based on measurement method "A" (single point LDV on stapes footplate) from 4 research groups (Dresden, Hannover, Shanghai, Zürich). Literature (ASTM) range is included as comparison.
