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.Įxamples of graphics application in practice The perception of the number of low frequencies depends on the volume according to the curves of equal loudness. 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.Īccording to this graph, you can estimate at what volume the headphones will be perceived more flat. The graph shows the change in the perception of the frequency response of the headphones when listening to music with a different loudness relative to the natural level.
Variation in frequency response in band from 40 Hz - 1 kHz Channel: Variation in frequency response in band from 30 Hz - 12 kHz Channel: The microphone is calibrated to 45 kHz with an appropriate frequency response correction.Īccording to the frequency response curve, it is possible to calculate the width of the frequency range. 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. 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. When connected to an amplifier, the frequency response can change. Subjective "flatness" is perceived differently from external conditions: the volume level of the external noise and noise isolation headphones. The frequency response of the headphones can be represented as the selected equalizer setting in the player, applicable to headphones with a flat sound. Graph of frequency response the shows the balance of the frequency of the headphones (reproduced frequency spectrum) in dB.

The difference in amplitudes of 6 dB is equivalent to a twofold ratio of signal levels. with an appropriate frequency response correction. The microphone is calibrated to 45 kHz F.A.Q. 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 /amp_comp.php>no compensation for the amplitude response F.A.Q.
is used to eliminate the interference of waves due to the use of a "point" microphone. For 0 dB, 20 μPa is assumed.īy 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. with the specified sound pressure dB SPL of 1 V RMS. is determined by the amplitude-frequency response curve F.A.Q.
