Description
Technical field
The present invention relates to a kind of acoustics, particularly a kind of acoustics of utilizing scalp to listen sound.
Background technology
At present, people come listening, music song, appreciation film and television sound with ear, also do not know to remove listening and music song and appreciation film and television sound with skin of head nerve, also there is no such product now.Once someone attempted to use bone conduction theory, and the bone conduction product of mechanics of communication is realized music appreciating, listened home theater film audio, but all failed.Because bone conduction theory can not solve the technical problem of sound field location in sense of hearing, cannot reach home theater solid space surrounding sound effect.Bone conduction oscillator is the device of communication speech use, not only without bass but also without high pitch, only has middle pitch, so that music effect is short of is very much extremely imperfect.Someone attempts single raise earphone more again, and result makes overall sound field more uneven on the contrary, cannot realize several locating effects of stereo-circulation at all.
The physiological property of the neural audition of scalp is: scalp neurokyme is heard the sound of 1Hz-20000Hz frequency range, especially this utmost point bass frequency range of 1Hz～20Hz, scalp nerve has all been listened out, and far beyond people's ear audition scope, people's ear can only be listened 20Hz～20000Hz.
It is all that balance is uniform that scalp nerve is listened sonority in 1Hz～20000Hz frequency range.Pleasant is that balance is uniform at 1000Hz～4000Hz, outside, to low frequency end with to front end, loudness sense of hearing all declines.
Scalp nerve is high to the resolution of sound, and discriminating power is extremely strong, can recognize various musical instrument voice fine distinction extremely on tonequality, tone color, musical note, and especially very little distortion, noise are all covered all at one glance.This is that we never experience with ear, because the duct of our ear, ear drum membrane, tympanum and three ear ossiculums are tuned in 1000Hz～4000Hz audio frequency range, this frequency range ear system works good linearity audio distortions is little, outside, to low frequency end with to front end, people's ear system enters inelastic region, and the trickle discriminating power of sound quality starts to decline.
Scalp nerve, to sound bearing sense, is all point-device at 1Hz～20000Hz.The sense of direction of people's ear below all frequencies more than 100 is very poor, especially in the middle of common room, can't hear low-frequency sound source from where.
The neural audition of scalp receives only the information that invests scalp place from neural sound inductor, in addition, does not receive any space sound, makes useful signal not be subject to external interference.
