Sensitivity headphone Jays v-Jays Small

Frequency band, Hz:
Channel:





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, 20 μPa is assumed.

By the sensitivity of the headphones, you can predict the volume level developed by the headphones at any chosen frequency with the known supply voltage to the headphones from the amplifier. Three-wave smoothing F.A.Q. is used to eliminate the interference of waves due to the use of a "point" microphone.

The frequency response in RAA is obtained through the reproduction and 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. During the measurements, a special amplifier was used with zero total output impedance over the entire frequency range, which required no compensation for the amplitude response F.A.Q.. The microphone is calibrated to 45 kHz F.A.Q. with an appropriate frequency response correction.

The difference in amplitudes of 6 dB is equivalent to a twofold ratio of signal levels.

    Impedance indicates the resistance of the earphone, depending on the frequency.

    The vertical scale of resistance is presented on a logarithmic scale.

    The impedance of the headphones affects the current consumption from the amplifier, changes in frequency response when connected to an amplifier F.A.Q. and indirectly on the sensitivity of the headphones F.A.Q. to the voltage.

    Perception of headphone frequency response curves of equal loudness ISO 226-2009 from headphone Jays v-Jays Small

    Channel:




    The graph shows the change in the perception of the frequency responseF.A.Q. of the headphones when listening to music with a different loudness relative to the natural level. When listening to headphones at a low volume, the perception of recoil in the low frequency range decreases, and when you listen to it at a high volume, it increases.

    According to this graph, you can estimate at what volume the headphones will be perceived more flat.

    The perception of the number of low frequencies depends on the volume according to the curves of equal loudness. (ISO 226-2009 Acoustics. Normal equal-loudness-level contours). For the base level, 72 dB SPL (live performance of several instruments with vocals without amplifiers with acoustics) is selected.When you select another base level, the dependence varies slightly and is suitable for almost all levels.
