Have you ever wondered what is the audio spectrum of certain instruments or voices? Probably most of you do not:) If you read further then you are probably interested in the link below. For those who record audio or are mixing in the studio or at home, this is even more useful, because it helps you to better define an equalizer settings (EQ).

If not, you can simply look out of curiosity:)

freqchart

It is an interactive chart with different values to certain instruments that produce sounds or vibrations of air, how they are perceived by humans, although more correctly the sound could be defined as any variation of pressure (air, water or other media) that can be detected by the human ear.

Human ear responds to sound intensity, which depends on the frequency. The frequency is expressed in cycles per second, in Hertz (Hz), in other words when you hear something you feel the air vibrating diferent times per second, low notes have less vibrations, while the high notes have more vibrations per second. In general the human ear hears between 20 Hz and 20 kHz, but the most sensitive to sound frequencies for the human ear are between 2kHz and 5 kHz.

And if I brought this up, the ones who don’t want to listen to neighbor’s music or other noises, as the case may be, or the ones of you who make music at home and need to soundproof the house you live in,  can learn how to soundproof your home and what materials they need here.
