Many manufacturers of headphones in the description indicate the frequency range. At the same time, the user expects them to reproduce sound in the stated interval, and the wider it is, the better.

- What is the headphone frequency range
- Which parameter to choose
Sound quality depends on the frequency range. The human ear is capable of distinguishing sounds from 20 Hz to 20,000 Hz. At the beginning of the interval are low-frequency sounds, and at the end - high-frequency sounds. The main task of the headphones is to play it correctly.
The audio device should not make extraneous sounds in the form of wheezing and hissing. To assess the ability of the device to reproduce high-quality sound is possible by the amplitude-frequency characteristic (AFC). This indicator is displayed as a graph of volume versus frequency. The straighter it is, the clearer the reproduced sound.
A single parameter in no way characterizes the sound of the headphones. Different device models cannot be compared with each other if the interval is indicated without deviations. In more expensive models of audio devices, manufacturers indicate the frequency response.
For example, a value of 20 Hz-20 kHz + -5 dB means that there will be no depressions or strong peaks throughout the interval.
Which parameter to choose
The optimal frequency range for headphones is in the range from 20 Hz to 20 kHz. However, many manufacturers are specifically trying to broaden this parameter. There are audio devices with an interval of 10 Hz-25 kHz. How to understand this, you ask? Of course, a person is not able to hear the full range of sound. On the one hand, manufacturers thus want to attract customers, and on the other hand, this means that the final drops in the amplitude-frequency characteristic will begin no earlier than these long-range borders.
NOTE. Broadening of thisparameter Is a marketing ploy.
The magnitude of the frequency range cannot be the main criterion in choosing headphones and other audio devices. A single parameter indicates only the interval, and not the linearity of the frequency response. According to the above values, you can not select an audio device, you can only exclude low-quality. The nature of the sound is best determined manually using a specific composition.
