ChenYN Piano Tuner 陈师傅调音-家庭音乐会钢琴调音（442 赫兹）

家庭音乐会使用442赫兹：

首先是需要与乐器配合（小提琴或者大提琴及部分管乐器等）以平衡整体音效。特别是具有乐团背景或者专业演奏者参与时确保其协调性。

第二就是适合人耳的听觉盛宴，营造活跃的家庭氛围。尽管442赫兹与440赫兹差异微小（约0.8音分），但对追求细腻音效的演奏者而言仍可察觉。

第三就是符合现代乐器的适应性，特别是最新制乐器（尤其弦乐）设计时已考虑更高张力的适应性，使用442能发挥其最佳性能。当然一些数字调音器或音频软件可能预设442 赫兹，部分家庭用户可能需要直接采用此标准。（日本、德国、美国等家庭在考虑音色的优化时多使用442赫兹）

442 Hz is used for family concerts:

First of all, it needs to be combined with musical instruments (violin or cello and some wind instruments, etc.) to balance the overall sound effect. Especially when it has an orchestra background or professional performers participates, it ensures its coordination.

The second is an auditory feast suitable for the human ear, creating a lively family atmosphere. Although the difference between 442 Hz and 440 Hz is small (about 0.8 minutes), it is still detectable for players who pursue delicate sound.

The third is to conform to the adaptability of modern musical instruments, especially the adaptability of higher tension has been taken into account when designing some new musical instruments (especially string music), and the use of 442 can give full play to its best performance. Of course, some digital tuners or audio software may preset 442, and some home users may need to adopt this standard directly. ( Japanese, German, American and other families use more 442 Hz when considering the optimization of sound)
