ChenYN Piano Tuner 陳師傅調音-家庭音樂會鋼琴調音（442 赫茲）

家庭音樂會使用442赫茲：

首先是需要與樂器配合（小提琴或者大提琴及部分管樂器等）以平衡整體音效。特別是具有樂團背景或者專業演奏者參與時確保其協調性。

第二就是適合人耳的聽覺盛宴，營造活躍的家庭氛圍。儘管442赫茲與440赫茲差異微小（約0.8音分），但對追求細膩音效的演奏者而言仍可察覺。

第三就是符合現代樂器的適應性，特別是最新制樂器（尤其弦樂）設計時已考慮更高張力的適應性，使用442能發揮其最佳性能。當然一些數字調音器或音頻軟體可能預設442 赫茲，部分家庭用戶可能需要直接採用此標準。（日本、德國、美國等家庭在考慮音色的優化時多使用442赫茲）

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)
