The units of normalized displacement are μm/Pa.
4000 Hz was used for human TM because 3000 Hz is associated with a narrow-band stimulus artifact.
Note: Statistically significant inverse correlation between frequency and maximum displacement: 8 × 8 PDMS (p < 0.0001), 8 × 8 PLA (p < 0.0001), 8 × 8 PCL (p < 0.0001); 16 × 16 PDMS (p < 0.0001), 16 × 16 PLA (p < 0.0001), 16 × 16 CL (p < 0.0003); fascia (p < 0.0001) and human TM (p < 0.0045).
