2. Nodules radiating from umbo are separated by a wide, shallow sulcus or furrow.
3. The displacement response and the specific acoustic impedance of the umbo were calculated from the velocity and sound pressure measured.
4. A strong correlation was found between the specific acoustic impedance of the umbo and hearing thresholds for hearing-impaired subjects (having otosclerosis or sensorineural hearing losses).
5. +Cap+ reddish-brown, 3 to 6 inches broad, fleshy; when young egg-shaped, and then Campanulate, and flattening out with a broad, obtuse umbo.
6. After designing a new type of laser Doppler vibrometer (LDV) that allows detection of displacement amplitudes down to about 1 pm, we used this device in 20 subjects to measure growth functions of the distortion products of otoacoustic emissions (DPOAE) as vibrations of the umbo.
