1. What is the core principle?High-quality, accurate reproduction of sound with minimal alteration
2. What is the historical origin?Emerged with technological advancements in audio recording and playback, particularly post-WWII
3. What is high fidelity sound?High fidelity, or hi‑fi, means the music sounds almost exactly like the original performance, with clear and clean sound and no extra noise.
4. Why is flat frequency response important in hi‑fi?Flat frequency response means every sound from low to high is reproduced at the right level, so the music stays true to what the musicians played.

Frequency Response: The range of sound frequencies an audio system can reproduce and the accuracy with which it reproduces them.
Dynamic Range: The difference between the quietest and loudest sounds a system can reproduce without distortion or noise.
Signal-to-Noise Ratio (SNR): A measure of how much louder the desired audio signal is compared to unwanted background noise.
