Description

Earphones with hearing-impaired healing function

The present invention relates to an earphone having a hearing impairment treatment function, and naturally relates to a functional earphone that functions to treat hearing loss or tinnitus and improve and prevent hearing impairment while wearing the earphone.

As described above, the use of the earphone of the present application prevents hearing hair cells (Auditory Hair Cell) damage that causes hearing loss and provides the ability to naturally treat hearing impairment while enjoying sound through the earphone through the Threshold Sound Conditioning (TSC), an acoustic stimulation treatment. It is a functional earphone.

On the other hand, in the conventional earphone, the front of the speaker faces the eardrum in a closed ear, so that all sounds, including noise generated by the speaker, are directly and strongly transmitted to the eardrum without filtration.

And after a certain period of time, the eardrum is no longer able to tolerate and begins to feel tired. If it is not perceived and continues to be supplied, the oversupply volume will eventually cause hearing impairment due to damage to the hair of the auditory hair cells. Difficulties in communication have led to the inconvenience of life and exposure to various risks of accidents when walking.

2. Description of the Related Art Recently, with the rapid development of various media media and playback devices, the use of earphones and headphones by various people is increasing, and the usage time thereof is also increasing day by day.

This popular culture can have a more adverse effect in growing youth and adolescence, and it is emerging as a social problem due to hearing impairment (such as hearing loss). In general, earphones, which are the main culprit of hearing impairment, are small-sized handsets designed to be mounted on the ears. Earphones are short for earphone receivers, and the structure of the earphones is the head of the head and the jack that connects to the sound equipment and the head of the head. It is made of a cable to connect with.

Even though the eardrum of the human body is a very sensitive organ, it is indiscriminately used by raising the sound indiscriminately without disclosing which sound from the speaker is the sound (static sound) that the user should listen to and what corresponds to the noise (noise). Hearing loss has also emerged as a social issue.

The TSC applied to the earphone of the present application is an abbreviation of THRESHOLD SOUND CONDITIONING, and generates a small sound energy, a threshold level of fine acoustic energy for each frequency so that the auditory neurons react, thereby improving hearing by stimulating hearing.

The TSC can be said to be a state-of-the-art technology that stimulates the repair of hair cells by dividing and stimulating the auditory cells of the cochlea in groups.

On the other hand, it is found that the cause of the hearing loss is that the destruction of the inner ear due to the pressure reversal of the outer ear and inner ear due to the hermeticity is more important than the volume factor, and the increase in the inner ear pressure is the main cause of hearing loss.

In recent years, the diagnosis of hearing impairment among adolescents has also rapidly increased. According to the National Health Insurance Corporation, in 2016, out of 288,032 patients diagnosed with hearing loss, 38% of those under 30 were 10,112.

This can be attributed to prolonged exposure to excessive noise or wearing earphones and hearing high notes.

This means that hearing loud cells over 100 decibels (dB) over a long period of time through these earphones can damage hearing cells.

On the other hand, most hearing loss occurs with age. Hearing loss gradually declines after 30s, and 30-40% of hearing loss in the 60s is "I do not hear well, and hearing loss is accompanied by noise and dizziness."

When such hearing loss begins, isolation from people around you disappears, depression naturally follows, and even dementia rates increase by 3-4 times.

Deafness like this is common and cannot be passed lightly, and the causes of hearing loss in older adults are aging *? * Noise, smoking, and high blood pressure. In particular, noise exposure can be said to be fatal, and in general, people can hear sound in the audible frequency range from 20Hz to 20K Hz, but the listening environment is deteriorating due to the increase in living noise.

In particular, in a recent study, 70% of all earphone listeners have hearing loss due to noise-induced hearing impairment, and if this develops, teenagers and children are almost at risk of hearing impaired hearing impairment in both middle and old age. Is being reported.

Patent Registration Publication No. 10-1261625 (Registration Date: April 40, 2013) Patent Registration Publication No. 20-0431196 (Registration Date: November 09, 2006) Patent Registration Publication No. 10-1520800 (Registration Date: May 11, 2015) Patent Registration Publication No. 10-1535112 (Registration Date: July 02, 2015)

In general, earphones are electronic devices that simply insert small speakers that are electrically connected into the ears, and often have hearing problems due to the structure of the speaker unit cabinet, excessive supply of mixed noise, and air pressure generated by the speakers. .

Threshold Sound Conditioning (TSC) is the smallest sound energy value at which a hearing neuron starts to react and generates micro acoustic energy of a threshold level, which is a frequency, by frequency, and supplies it to the hearing. It is a new technology that improves without surgery.

In other words, if you continue training to hear the sound at a level near the smallest sound level (hearing threshold), the boundary goes down, creating the effect of improving the ability to hear the sound, and the use of audio equipment and various noise exposures If the hearing loss once decayed, the degree of hearing loss may deteriorate severely over time.

The auditory cells of the ear are classified according to the location of the cells, and when a specific cell is damaged, the hearing of the frequency is rapidly reduced.

The auditory cell stimulation method using these acoustic signals is the main audible band (250 ~ 12,000Hz)

It can be said to be a technology that fundamentally restores the neuroplasticity of the auditory nerve by hearing a high-resolution mid-frequency stimulus that selectively stimulates only certain damaged hearing cells in between.

In particular, modern people have noticeable deterioration of hearing ability in the high frequency region due to excessive use of sound device, and increase the output of the sound device in order to hear well even in areas where hearing is deteriorated. If not, the overall sound pressure rises, resulting in hearing loss.

Therefore, when hearing is deteriorated, the deteriorated hearing should be corrected for each frequency band so that the desired sound can be accurately understood, communication with the other party can be prevented, and hearing loss is prevented.

Therefore, it is connected to a TV, radio, MP3, telephone, and other sound devices, and the sound conversion device that listens to the sound is corrected for each frequency band to fit the user's hearing ability, so that it is heard with clear sound quality and damages the ears. It needs to be prevented.

The present application relates to an earphone having a function of treating a hearing impairment as described above, and relates to a functional earphone that performs a function of treating hearing loss or tinnitus and preventing hearing impairment while enjoying music while wearing the earphone naturally.

Currently, hearing loss has been attempted to develop application software for the treatment of hearing loss using stem cells or drugs, but it is still at the level of animal testing.

On the other hand, permanent damage to the auditory hair cells of the inner ear causes sensory nerve hearing loss, which causes communication difficulties. The auditory hair cells in the inner ear are receptor cells that transmit acoustic stimuli.

Regeneration of damaged hair cells in the damaged inner ear provides a new chapter of hearing treatment in situations where there is currently no treatment other than hearing aid devices and prevents damage to hearing hair cells that cause hearing loss while using the earphone of the present application, and is an acoustic stimulation therapy TSC It relates to a functional earphone having a function to naturally treat hearing impairment through.

The present invention relates to an earphone having a function to treat and prevent hearing impairment as described above, and relates to a functional earphone that functions to treat hearing loss or tinnitus and prevent hearing impairment while wearing the earphone naturally. While preventing hearing damage to the hair cells that cause hearing loss, and through the acoustic stimulation treatment TSC technology, it relates to a functional earphone having a function to naturally treat hearing impairment while enjoying sound through the earphone.

Through the present invention, the earphone of the present invention prevents a headache caused by hearing (eardrum) fatigue and damage even if the user continues to use the earphone for a long period of time and for a long time, and increases the listening ability and noise of the earphone user It has the effect of contributing to the improvement of national health that can prevent the occurrence of hearing loss disorders.

The present invention relates to an earphone having a hearing impairment treatment function, as described above, to a functional earphone that functions to treat hearing loss or tinnitus and prevent hearing impairment by stimulating auditory hair cells causing hearing loss while wearing the earphone naturally. More specifically, it prevents hearing hair cells from causing hearing loss while using the earphones of the present application, and has the function to naturally treat hearing impairment while enjoying sound through earphones through the Threshold Sound Conditioning (TSC), an acoustic stimulation training method. It's about earphones.

The terms or words used in the present specification and claims should not be interpreted as being limited to ordinary or dictionary meanings, and the inventor can appropriately define the concept of terms in order to best describe his or her invention. Based on the principles, it should be interpreted as meaning and concept consistent with the technical idea of the present invention. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In recent years, many young people who use public transportation such as subways and buses wear earphones, and if you look at the street, you can easily see that most teenagers walk on the street and listen to music while walking through the earphones and do not detect the surrounding sounds. You can often encounter things that lead to accidents.

When these teenagers listen to loud music for a long period of time, hearing loss occurs, and the reason for the hearing loss is mostly dominant earphone noise, and it has been reported that teenager noise hearing loss has increased by 30% in the last 5 years.

On the other hand, in a quiet place, when the sound level is 40dB, the earphone volume, which can be easily heard, is raised to 115dB in the subway (80dB), and in the case of 85dB 8 hours, 105dB 2 hours, noise-induced hearing loss occurs, and further, it is very uncomfortable for social life.

The present application was devised to solve this hearing loss, and the TSC applied to this application, which is an abbreviation of Threshold Sound Conditioning (TSC) or Trigger Signal Control (TSC), actually stimulates the threshold of hearing and actually improves human hearing. This is a non-drug, non-invasive method that is a new technology;

So far, this technique is the only way to cure sensorineural hearing loss and enhance hearing.

The principle of this TSC technology is based on the human auditory system that converts the sound from the outside of the cochlea into an electrical signal, and the auditory hair cells of the cochlea are arranged with a unique band like a piano keyboard.

Each auditory hair cell responds only to sound in a specific band, so if there is a problem in a specific band, adjustment of the auditory hair cells in the corresponding band in the corresponding band is necessary and activating the cells in that band. Can be said.

If there is an abnormality in a specific band of auditory hair cells, a higher volume than usual is required to hear the sound of the band, and with this principle, the program is tested at the minimum value by each band of the auditory hair cells (INDEX1 to INDEX9). Thus, abnormal bands are found among the hearing bands of the hearing impaired.

Meanwhile, the human cochlea has 15,000 auditory hair cells in the cochlea, and these cells respond to different sounds, such as piano keys.

For example, there are cells that respond to the frequencies of sounds coming into the ears, such as the sounds of bats, women, men, and electrons. If the hearing cells responding to consonants and vowels are uncomfortable, the scores on the English listening test may be poor.

However, the role of these cells is to transmit sound to the brain when sound comes in from the outside.

'My hair cells (about 3,500 cells / centriotic hearing cells) are classified into' hair hair cells (about 15,000 cells / centrifugal inhibitory cells) 'that regulate the sound coming from outside.

That is why hearing cells are tested for health or not.

Normal (~ 24dB), mild hearing loss (25 ~ 39dB), moderate hearing loss (41dB ~ 54dB), medium-sized hearing loss (55dB ~ 69dB) From here, wearing a hearing aid is necessary for daily conversation, and cochlear implant surgery for fundamental treatment This is necessary and the value of these test results is called the threshold.

The TSC of the present invention is a technology that fundamentally improves hearing problems such as hearing loss and tinnitus, and takes a method of selectively stimulating only certain damaged hearing cells in the cochlea in charge of hearing, and listen to high-resolution mid-frequency stimulation sounds through the earphones to the ear for a certain period of time. It is a breakthrough technology that activates the function of hearing cells.

Hereinafter, the main configuration of a functional earphone having a hearing impairment treatment function of the present invention will be described in detail with reference to the accompanying drawings in order to help understanding of the present invention.
