Automated human temporal-bone experiments

Abstract Temporal-bone (TB) experiments are useful for the investigation of middle-ear and inner-ear transfer properties, analysis development active or passive middleear prostheses related devices. To acquire mechanical (ME) response, Laser-Doppler vibrometry (LDV) is utilized as a preferred method. In most setups, exact measurement point chosen on biological structure interest well direction corresponding vibration not precisely defined unknown reproducibility. Hence, an automated setup controlling coordinates TB developed tested. test reproducibility, TBs were measured with ER7C ER10C probe microphones employing small industrial robot to position ME points align it laser beam. The data acquired at same locations different time processed compared. Measured functions indicate noticeable differences some frequency ranges. Nonetheless, reproducibility positioning repeatedly proved itself relatively accurate, if no manipulations in made. conclusion, current study shows that LDV system principle capable adapt changes during intermediate preparation steps. With more data, stability can be verified, additional improvements
