The conductive hearing loss definition is as the following.
Hearing loss is divided into:
Conductive Hearing Loss
Neurosensory or Sensorineural Hearing Loss
Mixed Hearing Loss
When Mixed Hearing Loss is a combination of the other two, Conductive Hearing Loss refers to sound energy entering inner ear to be wakened caused by structural and dysfunction in the conduction path of the outer ear and middle ear, at the meantime, Neurosensory Hearing Loss is a sensory disease, which refers to the damage of nerve conduction pathway related to the cochlea or the auditory nerve to the auditory center in the inner ear, and leads to hearing loss or even disappearance.
Conductive hearing loss occurs when sound is blocked in the ear canal or middle ear.
The passage of sound may be blocked due to the obstruction or damaged structure of the outer ear, ear canal, or middle ear.
For people with conductive hearing loss, the sound will decrease in volume on the way to the cochlea of the inner ear.
Conductive hearing loss can be caused by the following factors:
(1) Earwax accumulation in the ear canal;
(2) Repeated middle ear infections (otitis media);
(3) Chronic infection;
(4) Middle ear growth (cholesteatoma);
(5) Abnormal bone growth near the middle ear (otosclerosis).
People with conductive hearing loss will find it difficult to hear soft sounds at all pitches (whether bass or treble).
Any problems when transmitting sound energy to the cochlea (the hearing part of the inner ear) can lead to conductive hearing loss. Common causes of conductive hearing loss include blockage of the ear canal, a hole in the ear drum, problems with the three small bones in the ear, or fluid in the space between the ear drum and the cochlea. Fortunately, most cases of conductive hearing loss can be improved.
Symptoms of conductive hearing loss may vary depending on the exact cause and severity, but may include or be related to:
(1) Deep listening;
(2) Sudden or continuous hearing loss;
(3) The ears are full of "stuffy" feeling;
(5) Pus in the ears;
(6) Ear pain or tenderness.
There are several types of conductive hearing loss. Certain types of conductive hearing loss can be corrected with hearing aids. If the Corti organ in the cochlea is functioning normally, hearing aids can help transmit sound to the outer or middle ear.
Other types of conductive hearing loss can be treated with medication or surgery. However, medical procedures may not completely reverse the conduction loss. Therefore, people with conductive hearing loss can usually benefit from hearing aids.
Bone Conduction is such a technology that transmits the vibration of the sound wave to the inner ear through bones, jaw, skull, without covering on the ear canal, as we can understand from this, Bone Conduction does not involve the outer ear and middle ear.
For now, Bone Conduction is always used in Hearing Aids since the last century. In the business field, consumers can see Bone Conduction Earphones as the most commonly commercialized product.
When Lavoli researched and developed Bone Conduction Musical Lollipop, consumers can hear the music via their bones instead of their ears, people are surprised. People come to us to ask questions, can Bone Conduction Musical Lollipop let people suffering from hearing loss hear again? Our answer is: Technically speaking, a person who is completely defined as Conductive Hearing Loss by a doctor shall be able to hear via Bone Conduction Musical Lollipop. Unfortunately, the cause of disease of many people with hearing loss is comprehensive. That is why we will suggest that just have a try on Musical Lollipop, it is a hope.
Surprisingly, bone conduction was found to conduct sound better than air conduction. Air conduction uses air to transmit sound to the ear canal and tympanic membrane, while bone conduction uses vibrations received by the ear's "specialized nervous system" to send specific sounds. Through tests conducted by researchers, people noticed that bone conduction sound is louder than air conduction sound. And using this advanced technology, our sound lollipop can not only let the person you care about hear the sound, but also let him hear the sound more clearly than the equipment using air conduction technology. With the help of bone conduction technology, a child suffering from conductive hearing loss can enjoy the beautiful music or stories by Lavoli lollipop. Does it sound great?
