This study was carried out to investigate the voice characteristics of 40 healthy females with no voice disorders, ranging in age from 60 to 84 years (X = 68.2+/-5.74 years). Measurements over all the entire phonational range were obtained by phonetography. The subjects were asked to sustain the vowel /a/ in modal register for a minimum of 5 seconds in the highest and lowest intensities after hearing the semitones C, E, G, and A, over all phonational ranges. The results indicated expansion of the low and reduction of high ends of the pitch range, decrease of the pitch numbers of the vocal range, restriction of the lowest and highest limits of the intensity, and reduction of either the maximum phonational range and the phonetogram area. The phonetography technique has shown efficacy to investigate the voice characteristics of elderly females.
本研究旨在调查40名无嗓音障碍的健康女性的嗓音特征，年龄在60至84岁之间（X = 68.2±5.74岁）。通过声谱图法在整个发声范围内进行测量。在听到半音C、E、G和A后，要求受试者在所有发声范围内，以正常发声方式在最高和最低强度下持续发元音/a/至少5秒。结果表明，音高范围的低端扩展，高端缩小，发声范围的音高数量减少，强度的最低和最高限制受限，最大发声范围和语图面积减小。声谱图技术已显示出在研究老年女性嗓音特征方面的有效性。
