In this paper, biomimetic based physical ear model proposed for measuring the characteristics of a hybrid-acoustic sensor for fully implantable middle-ear hearing aid. The proposed physical ear model consists of the external ear, middle-ear, and cochlea. The physical ear model was implemented based on the anatomical structure and CT images of the human ear. To confirm the characteristics of the ear model, the vibrational characteristics of the stapes was measured after applying sound pressure to the tympanic membrane. The measured results were compared with the vibrational characteristics of the human temporal bone specified by ASTM F2504-05. Through the comparison results, the feasibility of the proposed ear model was confirmed. Then, after attaching the hybrid-acoustic sensor to the ear model, the output characteristics of the ECM and acceleration sensor were measured according to the sound pressure. The measured results were compared with previous studies using human temporal bone, and the usefulness of the proposed physical ear model was verified through the analysis results.

The study was carried out to investigate how the refining of pulps affects the stress-strain characteristics and physical properties of paper. SwBKP and HwBKP were refined with Hollender laboratory beater to obtain three levels of freeness(500, 400 and 300 ml CSF) at the different consistencies(0.5% and 1.0%). The effects of fines were also evaluated. The stresses and strains of papers made from SwBKP and HwBKP were increased with refining. The absolute value of strain in paper made from SwBKP was higher than those of paper made from HwBKP. We also found that the presence of fines increased the stress and strain significantly in both pulp types. The refining at lower pulp consistency gave higher stress and strain properties. Most physical properties of paper were improved with refining, but the effect of refining consistency depended on the characteristics of each physical properties.
