Abstract

The invention relates to a deaf sound discerning apparatus. The apparatus adopts a microphone to test sound and amplifies the sound in the vicinity of a plurality of frequency points for respective sampling and testing and a plurality of intensity signals are acquired. The intensity signals are used for modulating the vibration amplitude or the frequency of a plurality of electromagnetic vibrators and the signal intensity of an optical display correspondingly. The value of signals in the vicinity of the frequency points are obtained based on the amplitude or the frequency and the light intensity, namely, the frequency and the value data of a sound signal are obtained by sampling so as to achieve the effects of discerning different sounds and the meanings of the sounds to a certain degree. The deaf sound discerning apparatus, lip-reading, dummy statement and a hearing aid used by a person of partial deafness can improve effects mutually. The deaf sound discerning apparatus can be used for communication function training for the deaf. The deaf can dance, and perceive calling and vehicle horn, and the like, by the apparatus. People who can not speak because of deafness can compare own pronunciations with the pronunciations of normal people by the apparatus and lip-reading, thus improving pronunciation and expression abilities. The inherent directivity of the microphone can be used for discerning the directions of the continuous and the discontinuous sounds. The sound discerning apparatus also can be used for discerning ultrasonic waves, such as animal language, and the like, by changing the testing frequency.

Description

technical field

[0001] The technology relates to a sound recognition instrument for the deaf, which belongs to life and rehabilitation appliances. Background technique

[0002] Deaf people can use cochlear implants to recognize sounds, but the installation cost of cochlear implants is nearly 200,000 yuan, so they can only be used by a very small number of the more than 20 million deaf people in my country. The invasive surgery of cochlear implants limits the number of users and brings Complications will occur and the residual congenital hearing loss of the hearing impaired will be caused. Those with damaged auditory nerves will not be able to use cochlear electronics at all. Those with the best cochlear effects can only understand 80%. Contents of the invention

[0003] Detect the intensity near several frequency points of the sound electric signal, and use the vibration amplitude or frequency of several electromagnetic vibrators and the display of the signal strength light...
