The Hardware Review: HyperX Cloud II Headset
Sound and Hearing Intro
Sound and Hearing Brief Intro
The Cloud II’s are wider range than what I refer to as standard 20-20 headphones. The frequency response ranges from 15 Hz to 25 kHz. Most headphones concentrate on the 20 Hz to 20 kHz range as this is generally accepted as the average range of hearing that most humans have although this varies from person to person. Additionally, the range tends to start wider and reduce as we age. What you may see advertised as “high definition audio” is sound that will often include frequencies outside of the standard 20-20 range.
In ideal conditions, the range can increase, but being reasonable, very rarely will most of us use our headphones in what could be considered “ideal conditions” (think commercial recording studios, sound testing labs etc).
Many of the “high definition audio” headphones which you’ll see advertised with ranges from single digit Hz to 40+ kHz (100 kHz for the $55,000 priced Sennheiser Orpheus headphones!) are good headphones, but generally you’ll find most companies tend to at a minimum split their focus from providing higher range headphones to increasing the quality of the range that most people can hear.
Couple all of this with the fact that I still know a lot of people who listen to mp3’s on their phones rather than any of the lossless audio formats and you may be wondering what the point of these high range headphones are.
On the off chance that you’re not aware of how much you lose in the conversion to mp3, I encourage you to go and check out:
where you can hear a recording of the sound lost from the original test control song in the development of the mp3 standard. Hint, you lose a surprising amount of sound.
