Frequency response
The so-called frequency response refers to the frequency range of sound equipment during playback and the relationship between the amplitude of sound waves and frequency. Generally, this indicator is tested with a frequency amplitude of 1000Hz as a reference, and the frequency amplitude is expressed in decibels (dB) using logarithms. The overall frequency response of the audio system is theoretically required to be between 20~20000Hz. In practical use, due to reasons such as circuit structure and component quality, this requirement is often not met, but generally it needs to reach at least 32-18000Hz.

The main technical indicators of the audio system.
What kind of audio equipment is Hi Fi? Hi Fi is an abbreviation for High Fidelity in English, which is simply translated as "high fidelity". Its definition is: a replayed sound that is highly similar to the original sound. So what kind of audio equipment's playback sound is Hi Fi? It is still difficult to draw a definite conclusion so far. Professionals in the audio industry use various instruments and methods to detect various indicators to determine the level of Hi Fi in equipment, while audiophiles often judge whether the equipment meets their desired Hi Fi through their own ears. To determine the high fidelity of playback sound, it is not only necessary to have high-performance equipment and software, but also to have a good listening environment. Therefore, there is still a difference between objective testing and subjective evaluation in accurately measuring the Hi Fi level of audio equipment.
