A low-cost miniature accelerometer attached externally on the nose is as effective in providing an indication of nasalization as a more expensive accelerometer used in previous research. The more limited bandwidth of this low-cost accelerometer does not restrict its ability to monitor nasalization because the vibratory energy of interest is below 2,000 Hz. The optimal placement of the accelerometer on the nose is over the lateral nasal cartilage, a position along the upper side of the nose, just in front of the nasal bone.
一个外部附着在鼻子上的低成本微型加速度计，在提供鼻音化指示方面与先前研究中使用的更昂贵的加速度计一样有效。这种低成本加速度计更有限的带宽并不限制其监测鼻音化的能力，因为感兴趣的振动能量低于2000赫兹。加速度计在鼻子上的最佳放置位置是在鼻外侧软骨上方，即沿着鼻子上侧、就在鼻骨前方的位置。
