Hearing loss and hearing aids

Now let us know briefly about hearing losses.

There may be several causes for hearing losses. Such as: Outer ear trauma (injury to the outer ear), Middle ear infections, damage to the tympanic membrane, or problems within the inner ear. Apart from this, High noise, age factors also contributes in the hearing loss.

Let us know the reasons for old age hearing loss.

Presbycusis:

What Is Presbycusis?

What are the symptoms? How can you know if you might have presbycusis?

Maybe you have noticed it is harder to hear people talk in noisy places.
Maybe you find yourself withdrawing more socially because of the frustrations of understanding people.
It is harder to hear sounds you are used to, like water running

How Does Presbycusis Happen?

As a person ages, their cochlear hair cells may become damaged. This results in a high-frequency hearing loss that can start as early as middle age. The
adult male of the species appears to be at greater risk, particularly if he is over 40 years old. In addition, there may be a genetic component to presbycusis.
Noise exposure is also known to play a role.

The impact of presbycusis can be seen in age-hearing loss charts. As a person ages, the middle ear also ages, going through physical changes that make it more difficult for a person to discriminate sound.

Statistics show a large percentage of older folks develop presbycusis. As many as half over 75 may have hearing loss. According to the a Profile of Older
Americans from the federal Department of Health and Human Services Administration on Aging, hearing loss was one of the most common condition experienced
by mature people in a survey.

As it is mentioned above that the Presbycusis (oldage hearing loss) is caused by damage to the cochlear hair cells or because hardening of the tympanic membrane, it results in high frequency hearing loss; therefore, this problem can mostly be solved with the help of hearing aids, but it is very essential that the hearing aid must be manufactured or adjusted to the each individual patients ability of hearing otherwise, the hearing aid may not be useful.

Though it is said that a normal person can hear between 20 HZ to 20 KHZ, it varies depending upon the age. However, normal hearing frequency of hearing is 50 HZ to 15 KHZ. As the age progresses, the hearing of high frequencies get decreased; therefore, each individual patient is to be assessed and adjusted the hearing aids, but unfortunately, it is fully not happening these days so the option of hearing aids as treatment is not proving much effective.
