We tested AKG K 420 in 2010~2014 on older HDM1 stand. Now all headphones of this type chạy thử on modern HDM-X stand. Frequency response in this report in not precision and it don"t compare with frequency response another headphones, which thử nghiệm on HDM-X stand. If possible, we’ll retest those headphones. You can give us AKG K 420 and we test its again và will refresh this report.

The sensitivity of the headphones F.A.Q. Is determined by the amplitude-frequency response curve F.A.Q. With the specified sound pressure dB SPL of 1 VRMS. For 0 dB, trăng tròn μPa is assumed.By the sensitivity of the headphones, you can predict the volume cấp độ developed by the headphones at any chosen frequency with the known supply voltage lớn the headphones from the amplifier. Knowing the value of your comfortable volume cấp độ , you can check the amplifier for compatibility. Three-wave smoothing F.A.Q. Is used khổng lồ eliminate the interference of waves due khổng lồ the use of a "point" microphone. The frequency response in RAA is obtained through the reproduction và analysis of a special noise signal with the subsequent generation of an impulse response. The frequency response plot is constructed from the spectrum of the impulse response. The difference in amplitudes of 6 dB is equivalent to a twofold ratio of signal levels.Original text in Russian report.
