Directions to sounds to the human ear, loudness, timbre, tone and sensitivity is different, there is a big difference.

1, a sense of direction: human ear on sound propagation direction and distance, location of discernment is very strong. Ear the auditory characteristics called "sense of direction".

2, loudness: for small voices, slight increase in loudness as long as the human ear can be felt, but when the sound reaches a certain value, the even larger increase, feeling no significant changes to the human ear. Often times the audible frequency is divided into 3 parts to determine the relationship between low, medium and high audio segments. That is: the bass in the band 20Hz-160Hz, audio 160Hz-2500Hz, high audio segment 2500Hz-20KHz.
