Human Ear Frequency Range



The critical quality measurement for any audio file is how well it sounds to your ears. Just how well can a human ear detect different frequencies?

The human ear is a very sensitive instrument that can easily be damaged. Any time you listen to music and you have your ears ringing afterwards, that's a sign that they've been harmed by the volume. If you love your music, keep your ears protected so you can KEEP enjoying your music!

Hertz (Hz) is the measurement of a sound's frequency - how low or high the sound is. For example, a bass drum thump is a low sound, while the whistle of a flute would be a high sound. Hertz is different from the decibel level of music. Decibel is how loud (airplane) or soft (whisper) the sound is.

The average range of hearing for children is from a low of 20 Hertz (20 Hz) to a high of 20,000 Hertz (20 kHz). By the time a person hits age 20, years of loud listening to rock music has already killed off the 'high tones'. The high range for a young adult has dropped to 16,000 Hertz (16 kHz). In another 10 years, a 30 year old is down to 12,000 Hertz (12 kHz).

So really, any music that plays outside those ranges won't be heard by a human ear anyway, and is worthless as far as humans are concerned. CDs only cover the range of 20 Hz to 20 kHz which is what kids can hear, and is beyond what adults can hear anyway. FM radio stations only carry sounds from 50 Hz to 15 kHz. When you make your audio files, therefore, whether they're MP3 or OGG or any other format, you only need to be concerned with what your own ears can hear. Play with different compression softwares and different settings. If the file is small and your ears can't tell the difference, that's all that matters.
