Introduction Over the years several investigations have been made of the acoustic behaviour of the external ear. Probe microphone measurements have been carried out at the entrance of the ear canal as well as at the eardrum for several angles of sound incidence. In the present work the acoustic...
以下哪一项是声压级( ) A. external ear canal B. sound pressure level C. cochlear chain D. tympa
Measurements of external ear transfer functions in the echolocating bat Eptesicus fuscus have revealed a prominent spectral notch that decreases in center frequency (50 to 30-35 kHz) as elevation decreases [Wotton et al., J. Acoust. Soc. Am. 98, 1423-1445 (1995)]. To examine the influence...
A physical replica of the external ear has been mounted in a large rigid plane. A point source of sound is placed a few centimeters from the earcanal entrance and at any desired angular position. The sound pressure at selected positions in the external ear is measured with a probe‐tube mi...
