What is the equal loudness of Chery Ant?

[LeEleanor]

Chery Ant's equal loudness is a technology that achieves the effect of separately boosting high, mid, and low frequencies while maintaining the same perceived loudness level. The function of equal loudness: The equal loudness control boosts the volume of high and low frequency components at low volume levels, ensuring the loudness ratio of low, mid, and high frequencies remains consistent with that at high volume levels. The reason for equal loudness: Due to the human ear's poor sensitivity to high-frequency sounds, especially low-frequency sounds, auditory compensation is required for high and low frequencies at low volume levels. This means significantly boosting low frequencies and moderately boosting high frequencies. In other words, when the volume decreases, the reduction in low-frequency components of the signal is less than that in high-frequency components. The equal loudness control meets this requirement, typically set at 8dB or 10dB.
