The size, shape, and position of the two ears of a person are basically the same. Many people think that the hearing of the left ear and the right ear should be the same. But when we discern the sound carefully, many people will turn their heads to try if they can hear clearly with the other ear as long as they cannot hear clearly. This is because the sensitivity of the left and right ears is different. Many boys are reminded to whisper to their left ear when chasing girls, so that girls are more acceptable. Is the left ear really more sensitive than the right ear?
The current mainstream view believes that the above statement is true. Modern technology is advanced. Physiologists carefully observe human EEG and find from it that the amplitude of human right brain is larger than that of left brain, because the sound vibrations felt by the ears are transmitted to the auditory center of the left and right brains through the auditory nerve, and the middle is passed through the corpus callosum. , So the vibration wave from the left ear crosses to the right brain through the corpus callosum, and similarly the vibration wave from the right ear is transmitted to the left brain. The amplitude of the right brain is relatively large, so the hearing of the left ear is more sensitive than the right ear.
But there will still be different voices. Some deaf-mute experts believe that the hearing of the left and right ears is different, and it is not entirely because the left ear is better than the right ear. For example, when listening to reports or speaking, the right ear is more sensitive than the left ear. This is because the language center is on the left. If you listen to songs in a busy or crowded street, the left ear can hear but the right ear cannot hear clearly.
