  2. R44 NT4 AT822 -36dB -51dB -44.36dB -65dB LV5 SENS5 -115dB -115dB -3dB -3dB 64dB 79dB LV5 SENS5 ノーマライズ -67dB -82dB R44 NT4 AT822 -17.5dB LV5 SENS8 -32.5dB -100dB -100dB -3.2dB -31.20dB -3.0dB 68dB 83dB LV5 SENS8 ノーマライズ -71dB -86dB

  3. R44 NT4 AT822 -20dB -5.66dB LV5 SENS10 LV5 SENS10 ノーマライズ -5.00dB -4.68dB 67dB 81dB -71dB -86dB R44 NT4 AT822 LV5 SENS10 -88dB -88dB 1kHzを入れないとどちらもー88dBであり、ノイズレベルは 同等である、しかし差がつく違いの最大原因は感度である事が わかる。 NT4はAT822より13dB~15dB利得が高い その差が、最終的なSN比の違いになる。
