The aim of this study was to evaluate changes in the acoustic features of voice in patients with sensorineural hearing loss.
Thirty male patients, between 35 and 53 years of age with postlingual bilateral symmetric severe sensorineural hearing loss, were included (group A). As a control group (group B), 30 normal-hearing male adults, aged 38 to 51 years, were identified.

Phonetically balanced sentences and sustained vowels a, e, and i were digitally recorded with the Multidimensional Voice Program (Kay Elemetrics) in all subjects.
The parameters estimated were the average of fundamental frequency (F0), jitter percent (jitter), shimmer, noise to harmonics ratio (NHR), voice turbulence index (VTI), soft phonation index (SPI), degree of voicelessness (DUV), degree of voice breaks (DVB), and peak amplitude variation (vAm).
Compared to the control group, in group A, the following acoustic parameters presented a statistically significantly higher value (p < .05) of F0 (137.2 Hz vs 120.0 Hz), jitter (1.93% vs 0.67%), shimmer (6.67% vs 3.81%), NHR (0.19 vs 0.10), SPI (12.9 vs 8.76), DVB (2.12% vs 0.01%), DUV (9.53% vs 0.51%), and vAm (23.12 % vs 12.06%). In group A, F0 was also significantly higher in the balanced sentences (126 Hz vs 111 Hz).
This study demonstrates that hearing loss affects voice production by changing its parameters, especially in subjects with marked hearing loss.
本研究旨在评估感音神经性听力损失患者的嗓音声学特征变化。
纳入 30 名 35 至 53 岁的后天性双侧对称重度感音神经性听力损失男性患者（A 组）。作为对照组（B 组），选取 30 名听力正常的 38 至 51 岁男性成年人。

所有受试者均使用 Multidimensional Voice Program（Kay Elemetrics）数字化记录语音清晰的平衡语句和持续元音 a、e 和 i。
所估计的参数包括基频（F0）、抖动百分比（jitter）、颤动、噪声与谐波比（NHR）、嗓音湍流指数（VTI）、柔和语音指数（SPI）、无声音量度（DUV）、声音中断度（DVB）和峰值幅度变化（vAm）。
与对照组相比，A 组的 F0（137.2 Hz 比 120.0 Hz）、jitter（1.93% 比 0.67%）、shimmer（6.67% 比 3.81%）、NHR（0.19 比 0.10）、SPI（12.9 比 8.76）、DVB（2.12% 比 0.01%）、DUV（9.53% 比 0.51%）和 vAm（23.12% 比 12.06%）等声学参数均具有统计学显著差异（p<0.05）。此外，在 A 组中，平衡语句的 F0 也明显更高（126 Hz 比 111 Hz）。
本研究表明，听力损失通过改变嗓音参数影响发声，在有明显听力损失的患者中尤其如此。
