ndltd-MIT-oai-dspace.mit.edu-1721.1-310802020-07-15T07:09:31Z Measuring the neck transfer function of laryngectomy patients Meltzner, Geoffrey S. (Geoffrey Seth), 1973- Kenneth N. Stevens and Robert E. Hillman. Measurements of the Neck Transfer Function (NTF), defined as the ratio of the estimated volume velocity that excites the vocal tract to the acceleration measured at the neck wall when the neck is driven by a mini-shaker, were made at three different positions on the necks of ten laryngectomized subjects (five males and five females) and four normal laryngeal speakers (two males and two females). A mini-shaker driven by broadband noise, provided excitation to the necks of subjects as they configured their vocal tracts to mimic the production of the vowels /a/, /ae/, and I/. The sound pressure at the lips was measured with a microphone and an impedance head mounted on the shaker measured both the force and acceleration. Overall, the results indicated that the neck wall passes low frequency sounds better than high frequency sounds. A comparison of the NTFs of four subject sub-groups revealed that the NTFs of female laryngeal speakers differed from the NTFs of the other groups (male laryngeal speakers, laryngectomized males and laryngectomized females). In addition, there was a notable amount of inter-subject variability even within a subject group. The results also indicate that the NTF is relatively independent of the amount of pressure with which one applies the shaker to the neck. These results should be useful for aiding in the design of an improved neck-type electrolarynx. Massachusetts Institute of Technology.
