As many as 10% of our Kentucky population suffers from hardness or hearing loss. A large part of this can be helped with hearing aids, provided that these problems quickly come to light and can be diagnosed. Unfortunately, this is not always the case in practice: the majority of these ten percent (up to 75%) do not test their hearing. The result is not only that the hardness or hearing loss continues to worsen, but also that the quality of life of that group is drastically reduced.

1. Time Is Running Out! Think
About These Ways To Change
Your hearing loss solution

2. Hearing loss affects many people in the world in different ways. Over time,
hearing loss can affect your communication with others and negatively
affect your relationship with others. If you ignore the hearing loss, physical
symptoms may also evolve into psychological symptoms. This is why we
need to find a solution quickly. If you have hearing loss, the following can
help you understand it. In fact, you are one of the 500 million people with
hearing problems in the world. In most countries, this means that more
than one in six people have varying degrees of hearing loss. For at least
90% of hearing aid users, the matching of a suitable hearing aid helps
them improve their communication skills, which is very encouraging news.
This news also means that you can get a solution to hearing impaired.

3. HEARING AND HEARING LOSS
To understand the different causes of hearing loss and how Xiga Aachen enhances hearing levels, it is
important to understand how the ear interacts with the brain to obtain sound.

4. Symptoms of hearing loss
According to different degrees and reasons, hearing loss is divided into different types. But the
symptoms of hearing loss are basically the same. If you answer any of these questions in the
affirmative, you may have some level of hearing loss. We strongly recommend that you take a
hearing test at a professional hearing facility.
• Do people always say that your TV or radio is too loud?
• Have you missed someone’s call and phone because you did not hear the doorbell or ringtone?
• Are you having trouble communicating in a crowded and noisy environment?
• Do people look mumbled or unclear when communicating with you?
• Has anyone told you how loud you are?
• Do you often ask others to repeat what they have said?
• Is it advisable for your friends and family to use your hearing aid?

5. Causes of hearing loss
Many factors can affect your hearing and cause hearing loss, including:
• Long-term exposure to noise
• Genetic
• disease
• Ototoxic drugs
• trauma
• Ear canal embolism
• Age aging

6. Noise-induced hearing loss
Long-term exposure to more than 85dB of
noise can cause hearing loss. For
example, if you have just finished a large
symphony concert or have finished
listening to MP3s at a high volume, you will
often find that listening sounds seem to
have dropped. This is because slender hair
cells in the auditory organ have been
temporarily damaged, but after a period of
quiet, the damaged hair cells will recover.
This phenomenon is called transient
threshold shift (TTS).

7. However, if you are exposed to high levels of noise for long periods of time, these slender hair
cells will be permanently damaged and unable to recover. Call it a permanent threshold shift
(PTS). Deafening music on concerts, nightclubs or headphones is especially dangerous. For
example, the music can be easily amplified to a dangerous level of 110-120dB after it has been
amplified by headphones. Of course, sudden loud sounds such as gunfire may also cause
noise-induced hearing loss. People working in high-noise environments should also pay more
attention to protecting their hearing and protect their ears, such as construction workers,
workshop workers, airport runway maintenance personnel and musicians.
Noise may cause tinnitus. Tinnitus is the sound of a different type of noise in the interior of one
or both ears than in real life. In fact, these voices do not exist, but in different forms and
volumes continue to echo in the brain.
What can you do?
Preventing is always better than treatment, wearing the appropriate hearing aid, such as the
market commonly earplugs or earmuffs, can also be tailored to different filtering devices, etc., to
protect the hearing is the most correct and effective way.

8. Hearing loss type
Hearing loss may be caused by either of the following two ways or both.
1. Conductive hearing loss
Conductive hearing loss occurs
when there is a problem with the
outer ear and middle ear or if it
does not work properly. Therefore,
the sound waves cannot be
effectively transmitted into the
inner ear. It is hypothesized that
conductive hearing loss due to
temporary dysfunction is usually
curable by surgery or (and)
medications.

9. Common causes of conductive hearing loss
• External ear trauma
• Obstruction of the external auditory meatus caused by (earwax) or other small items such as
small beads or insects
• Outer or middle ear infections
• Tympanic membrane perforation
• Congenital malformations (such as Down’s syndrome, facial hypoplasia syndrome, Trechr
Collins syndrome or achondroplasia (dwarfism)

10. The audiogram on the right shows conductive hearing loss. In this example, the inner ear works
properly, but some factors inhibit the transmission of sound through the outer ear (middle ear) to the
inner ear. The top audiogram shows a right ear hearing from 30 to 50 dB HL and a left ear hearing from
35 dB to 45 dBHL. This person will only be able to detect some segments of normal speech that are
about 65 dB in intensity. A person with normal hearing has a maximum dynamic range of 65dB between
the hearing threshold (0 dB) and the speech level (65 dB). People who have the above hearing loss
have a dynamic range of only about 20 dB. This approximately 45 dB gap must be compensated to
ensure that the patient is properly aware of speech and sound.
On the basis of routine diagnosis, the necessary gain is usually provided by the following methods :
• Conventional hearing aids (sometimes have no effect due to chronic otitis media, suppuration,
external ear or ear canal dysplasia).
• Bone conduction hearing aids: After the pinna, place a vibration sensor on the skull using a headband
or holder.
• Bone Anchored Hearing Aid (BAHA): Attach a vibrational hearing solution to the skull using an
implanted screw.

11. If the inner ear is intact, the bone conduction hearing solution will not give any
amplification sound. Their job is to make the sound heard through the
appropriate vibrations of the skull and thus deliver the sound directly to the inner
ear. From there, the auditory process continues normally.
2 sensorineural hearing loss
Sensorineural hearing loss is the most common hearing loss. Problems usually
come from the inner ear and the auditory nerve. Mostly due to the damage of
the inner ear (cochlear). Under such conditions, the hair cells in the cochlea are
impaired, unable to transmit electrical signals to the brain. Sensory neurological
hearing loss may be caused by innate, may also be caused by acquired factors

12. Acquired factors :
Ototoxic drugs (damage auditory system) , Head trauma , Noise damage ,
Senile hearing loss , Ear infections, meningitis, encephalitis, Other diseases

13. The bottom of the descending type audiogram, symmetrical decline of both ears, low-
frequency hearing is 20dB, high-frequency hearing decreased to 75dB. Most of these hearing
loss losses can be obtained with a suitable hearing aid.
If the speech-related frequency of hearing loss is between 80 and 90 dB or higher, it
becomes more difficult to fully understand the speech. The problem here is that patients with
very severe hearing loss still feel uncomfortable like normal people when they hear loud
voices. Therefore, when configuring a hearing aid, the complete speech spectrum must be
adjusted to the residual dynamic range of the patient, but a typical hearing aid may not
provide sufficient gain if the dynamic range has been reduced to 10-20 dB.
At this point, the patient may consider implanting a cochlear implant (CI). Cochlear implants
replace the function of the inner ear and translate the sound directly into electrical signals that
stimulate the auditory nerve and transmit electrical signals to the central nervous system.
Cochlear implants, however, must be speech-induced deafness or cochlear implants before
they are 4 years old. After a long period of training, they have a certain degree of learning
ability to enable normal functioning of the brain to explain the sound function

14. Cochlear implants are not suitable for every hearing-impaired person. Even after the implants are
implanted, they still require a lot of auditory training and continuous support to help the hearing
impaired to enhance their hearing.
Mixed hearing loss
If the air conduction and bone conduction threshold are above 20dB, and the difference
between the two is greater than 15dB, that is, mixed hearing loss. Such hearing loss
depends on the extent of the loss, the physiology of the patient’s ear, and other possible
influencing factors to determine the appropriate treatment, and all hearing aids that can
be used in two types of hearing loss are available:
• Conventional hearing aid
• Guided hearing aid
• Bone Anchors (BAHA)
• Implantation of cochlear implant (CI)

15. According to the
patient’s bone
conduction and the
degree of loss of air
conduction, select the
appropriate hearing
solutions.
Hearing loss
Hearing loss is divided
into different grades
according to the
severity of the injury.
• 25 dB HL Normal
• 26 – 40 dB HL Mild
• 41 – 60 dB HL Moderate
• 61 – 80 dB HL Heavy , > 80 dB HL Very Heavy
