Brief information
Graph of frequency response F.A.Q. the shows the balance of the frequency of the headphones (reproduced frequency spectrum) in dB. 0 dB is the average of the amplitude.

The frequency response of the headphones can be represented as the selected equalizer setting in the player, applicable to headphones with a flat sound. Subjective "flatness" is perceived differently from external conditions: the volume level F.A.Q. of the external noise and noise isolation headphones. When connected to an amplifier, the frequency response can change F.A.Q..

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.

According to the frequency response curve, it is possible to calculate the width of the frequency range F.A.Q..

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

Brief information
Brief information
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.
