Sound Level test.
| This graph is a measurement of the noise value. Test is usually recorded from a position left from the front side part of the drive bezel by about 13cm(width in one with a short jewel case). Tested with IEC651 TYPE2 standard sound level meter. A characteristic(blue line) is high frequency noise. C characteristic(red line) is low frequency noise. If C and A are almost the same values, the drive is howling that sounds high. If C(red line) is much higher than A(blue line), the drive emits a jarring sound that sounds low. Comparison to other drives. |
