One Vietnamese gong set of nine flat and six bossed gongs was acoustically studied. Main partial (primary pitch) for the flat gong was estimated by human hearing sense, suggesting that the primary pitch was the second partial for flat gongs and the third partial for bossed gongs. Tuning controlled the balance of these primary pitches among the other partials and made two octaves (about 1200 and 1250 cents) within one gong set more distinct in both flat and bossed gongs. All the gongs were related to each other by a perfect fifth and/or the above two octaves.

调音前后越南扁锣和鼓式锣的声学分析

一套越南锣，九个平锣和六个凸锣进行了声学研究。平锣的主分音（primary pitch）是用人的听觉来估计的，表明主音高是平锣的第二部分和鼓鼓的第三部分。调音控制了其他分音之间这些主要音高的平衡，并使一个锣组内的两个八度音阶（约 1200 和 1250 音分）在扁平锣和凸锣中更加明显。所有的锣都通过完美的五度和/或以上两个八度相互关联。
