Headphones generally produce sound through vibrations of the speaker diaphragm; however, at high volumes, the diaphragm may not vibrate fast enough, resulting in sound distortion. The lower the THD, the better the quality of the headphones. Most headphones have a THD of 1%, or even less, for high-end products.

To recap, a good pair of headphones should easily produce audio frequencies between 20 Hz and 20,000 Hz. Extended frequency responses may improve the sound quality of the headphones via our sense of feeling.

Frequency response is the range of bass, mids and treble. Some headphones offer wider ranges (for example, 5 to 33,000 Hz), but better frequency response does not always mean better sound quality. Below 20 Hz bass frequencies can be felt more so than heard, treble frequencies over 20,000 Hz are not always audible.

between 20 Hz to 20 KHz
Anything lower is too soft but higher than 28 KHz will give you noise pollution. However, the sweet spot ranges between 20 Hz to 20 KHz – perfect for any competitive game. Just don’t overthink the numbers too much. But do take note that headsets that include a 20 Hz to 20 KHz frequency response don’t come cheap.

Myth 1: The earphones and headphones with the widest frequency range sound best. A frequency range is supposed to state the lowest and highest frequency produced by a headphone. Loud sounds (high SPLs) won’t necessarily damage the product, but excessively high electrical signals can.

Distinguished. Frequency = 1/Time. So the higher the frequency, the smaller the time interval between samples when recording the source data and the better the sound quality of the recording (and the larger the size of the source file).

Technique 1 : Frequency Peak Pick The easiest way to compare frequency response functions is by simply picking the frequency of the peak(s) on an FRF. This is traditionally how Sandia has compared the similarity of the two transfer functions; this technique is very visual and easy to understand.

The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

A headphone or earphone can put out dangerous sound pressure levels (SPLs) before hitting its breakdown volume. Loud sounds (high SPLs) won’t necessarily damage the product, but excessively high electrical signals can.

most headphones actually have a harder time reaching the air frequencies and above cause they’re usually purposely rolled-off so it’ll be hard to actually have headphones that can extend up to 20khz flat,but that’s of course if your hearing is up to the task of hearing that high still.

Frequency response targets are usually devised in a way that imagines if a headphone’s frequency response perfectly matches the target curve, it would sound ‘neutral’. However because there’s no current consensus on what neutral is – at least for headphones – we have a number of potential target curves to choose from.

Correlated double sampling. When used in imagers, correlated double sampling is a noise reduction technique in which the reference voltage of the pixel (i.e., the pixel’s voltage after it is reset) is subtracted from the signal voltage of the pixel (i.e., the pixel’s voltage at the end of integration) at the end of each integration period,…

The raw or uncompensated frequency response plot of a headphone is useful to some of the more advanced users, who are able to read and evaluate a headphone’s frequency response in its raw form and without compensation.

Some of the more advanced users are able to read and evaluate headphone frequency response in its raw form and without compensation. This will be especially useful to them if they have their own headphone compensation/target curve, which may differ from the compensation curve/target response used by RTINGS.com.
