The amount of electrical signal required to damage the product is higher than the distortion point. That's the point where the product stops increasing in volume and becomes more distorted. Earphones and headphones can be damaged by loud sounds.įalse. A headphone or earphone can put out dangerous sound pressure levels (SPLs) before hitting its breakdown volume. That is not only well out of the range of human hearing, but also says nothing about what happens between those two frequencies. Our ears are most sensitive between 100Hz and 10kHz, so the relative amount of energy that a headphone produces throughout this range is much more important than what happens ≤20Hz or ≥20kHz. A frequency range is supposed to state the lowest and highest frequency produced by a headphone. The normal range of human hearing is approximately 20Hz to 20kHz. Some specs go WAY past that- like 5Hz to 50kHz- which is incredibly misleading.
The earphones and headphones with the widest frequency range sound best.įalse.
