調整訣竅:
- 發出的音量 (觀察 RMS value )要適當. 在合適的音壓之下. 才會有好的THD 表現
- 在沒有回音 的無響箱或無響室, 調整音量, 觀察THD 變化. 得到穩定且低的 THD 值. 就是 整個系統 ( 輸入源. 輸出檔) 的良好設定.
- 音量過大聲會失真(有二次諧波變大), 過小背景雜音比例大, THD 也會不好) 以 Lenovo 筆電 用耳麥 為例 音壓 (RMS value 應該落在 2000mV左右 THD 表現比較好
- 經過不斷的試驗才能找到 合理的音量 得到好的THD
聲源的 優化:
- 業界通常用 Hanning 作為音源的pre-process 提供給FFT分析軟件分析. 得到的spectrum 比較一致.
專有名詞
- THD ( Total harmonic distortion ) 总谐波失真- 维基百科，自由的百科全书
- Peak Power / Peak Frequency 在 Frequency domain 裡面最高位置的 頻率( x 軸) & level (Y 軸)
