What are hearing aid devices?


Hearing aid device stethoscope is a small electronic device that you wear inside or behind your ear. Makes some sounds higher so that a person with hearing loss or hearing loss can listen, communicate and participate fully in daily activities. Hearing aid device can help people hear more in quiet and noisy situations. However, only one in five people use the stethoscope.

The headset consists of three basic parts: a microphone, an amplifier and a speaker. The speaker receives sound through a microphone that converts sound waves into electrical signals and sends them to amplifier. The speaker increases the power of the signals and then sends them to the ear through a speaker.


How can hearing aid device help?

Hearing aid device are essentially in improving the hearing and speech understanding of people with hearing loss caused by damage to small sensory cells in the inner ear, called hair cells. This type of hearing loss is called sensorineural hearing loss. Damage can occur as a result of illness, aging, injury from noise or certain medications.

The speaker amplifies the vibrations of the sound that enter the ear. The remaining hair cells detect larger vibrations and turn them into nerve signals passed through the brain. The more damage to a person’s hair cells, the more severe hearing loss, and the greater the amplification of hearing needed to make up for this difference. However, there are practical limits to the amount of amplification that a stethoscope can provide. In addition, if the inner ear is severely damaged, even large vibrations will not be converted into nerve signals. In this case, the stethoscope will be ineffective.


How do I know if I need Hearing aid device?

If you think you may have hearing loss, see your doctor, who may refer you to a specialist in nose, ear and throat. An ear, nose and throat doctor is a doctor who specializes in ear, nose and throat disorders and will investigate the cause of hearing loss. An audiologist is the one who identifies and measures hearing loss and will conduct a hearing test to assess the type and degree of hearing loss.


Are there different types of hearing aid device ?

There are 5 types of hearing aid device. Behind the ear (BTE), Mini BTE, inside the ear (ITE), inside the ear (ITC) and fully in-channel (CIC)

The hearing aid device placed behind the ear (BTE) consist of a solid plastic case placed behind the ear and attached to a plastic ear mold that fits the outer ear. The electronic parts in the box are fastened behind the ear. The sound travels from the earpiece through the ear mold to the ear. BTE aids are used by people of all ages for mild to severe hearing loss.


A new type of BTE aid is open hearing. The small open auxiliary tools fit just behind the ear, with only a narrow tube inserted into the ear canal, allowing the channel to remain open. For this reason, open hearing aid device may be a good choice for people with earwax build-up, since this type of aid is less likely to be damaged by these substances. In addition, some people may prefer open hearing aid device because their perception of their voice does not seem “plugged in”.


ITE is perfectly fit inside the outer ear and is used for mild to severe hearing loss. The enclosure containing electronic components is made of hard plastic. Some ITE aids may contain some added features installed, such as a phone file. A phone file is a small magnetic file that allows users to receive audio through the speaker’s circles, not through their microphone. This makes it easy to hear conversations over the phone. The phone file also helps people hear in public facilities that have installed special sound systems called induction ring systems. Induction ring systems can be found in many schools, airports and halls. Young children do not usually wear ITE hearing aid device because the covers need to be replaced a lot as the ear grows.


Channel aid enters the ear canal and is available in two ways. The in-channel (ITC) hearing aid device are designed to fit the size and shape of a person’s ear canal. The headset is almost completely hidden inside the entire CIC channel in the ear canal. Both types are used for mild to severe hearing loss.


Due to their small size, it may be difficult for a person to modify and remove them. In addition, channel aids have less space for batteries and additional devices, such as a phone file. It is not usually recommended for young children or for people with severe hearing loss because their low size limits their strength and size.


Which of the hearing aid device will work better for me?

The headset that will work best for you depends on the type and severity of your hearing loss. If you have hearing loss in both ears, it is generally recommended to use two hearing aid devices because two aids provide a more natural signal to the brain that hearing in both ears will also help you understand speech and determine the source of sound.

You and your audiologist should choose the hearing aid device that suits your needs and lifestyle. Price is also a key consideration because hearing aid device range from hundreds to several thousand dollars. Similar to other equipment purchases, the method and features affect the cost. However, do not use price alone to determine the best earpiece that suits you. Just because one of the hearing aid devices is more expensive doesn’t necessarily mean it’s going to suit your needs better.

The hearing aid device won’t get your normal hearing back. However, through practice, the stethoscope will increase your awareness of sounds and their sources. You will want to wear the stethoscope regularly, so choose a comfortable and easy-to-use one. Other features to consider include parts or services covered by warranty, discretionary schedule, maintenance and repair costs, options and upgrade opportunities, and the company’s reputation for quality and customer service.


What questions should I ask before buying hearing aid devices?

Before you buy a medical headset, ask your audiologist these important questions:


  • What features will be very useful to me?
  • What is the total cost of hearing aids?
  • Do the benefits of modern technologies outweigh the high costs?
  • Is there a trial period for testing hearing aid device? (Most manufacturers allow a trial period of 30 to 60 days during which assistance can be returned for refunds.) What are the non-refundable fees if the assistance is returned after the trial period?
  • How long is the warranty? Can it be extended? Does the warranty cover future maintenance and repairs?
  • Can an audiologist make adjustments and provide services and minor repairs? Will lenders be provided with assistance when repairs are needed?
  • What are the instructions provided by an audiologist?


How do I adapt to my hearing devices?

It takes time and patience to use hearing aid device successfully. Wearing your hearing aid devices regularly will help you adapt to them.

Learn about the features of your headset. With your audiologist, train to enter and take out the aid, clean it, select the right and left aid, and replace the batteries. Ask how to test it in listening environments where you have hearing problems. Learn how to adjust the utility’s volume and program it for very loud or very low sounds. Work with an audiologist to make you feel comfortable and satisfied.

You may experience some of the following problems when you adapt to wearing your new assistant.

I feel uncomfortable with my hearing aid. Some individuals may find the hearing aid device a little uncomfortable at first. Ask your audiologist how long you should wear a stethoscope while adjusting to it.

My voice sounds so loud. The sensation of “connectivity” that causes the voice of a speaker user to appear higher inside the head is called a blockage effect, which is very common for new headphone users. Check with your audiologist to see if a patch is possible. Most individuals get used to this effect over time.

I hear a whistling sound in my ear. The sound of wheezing can be caused by a hearing aid that does not fit, functions well or is clogged with ear wax or fluid. Check with your audiologist for modifications.

I hear noise in the background. The speaker doesn’t completely separate the sounds you want to hear from the sounds you don’t want to hear. However, sometimes, you may need to adjust your hearing. Talk to your audiologist.

I hear tinnitus when I use my cell phone. Some people who wear hearing aids or have hearing aids with radio frequency interference caused by digital mobile phones. Both hearing aid device and cell phones are improving, however, these problems occur less frequently. When equipped with a new audio utility, take your cell phone with you to see if it will work well with help.


How do I take care of my hearing aid device?

Proper maintenance and care will extend the life of the hearing aid. Make it a habit:

  • Keep the hearing aid device away from heat and humidity.
  • Clean the hearing aid device as instructed. Ear wax and ear drainage can damage hearing.
  • Avoid using hair sprays or other hair care products while wearing hearing aid device.
  • Turn off the hearing aid device when they are not in use.
  • Replace empty batteries immediately.
  • Keep replacement batteries and small assistance out of reach of children and pets.


Are new types of hearing devices available?

Although they work differently from the hearing aid device described above, implantable hearing aid device are designed to help increase the transmission of acoustic vibrations that enter the inner ear. MEI is a small device attached to one of the middle ear bones. Instead of amplifying the sound that travels to the eardrum, MEI moves these bones directly. Both methods have the ultimate result of strengthening the acoustic vibrations that enter the inner ear so that they can be detected by individuals with sensorineural hearing impairment.


The BAHA is a small device that is attached to the bone behind the ear. The device transmits acoustic vibrations directly to the inner ear through the skull, bypassing the middle ear. BAHAs are generally used by individuals with mediating ear problems or designed in one ear. Since surgery is required to implant any of these devices, many hearing specialists feel that the benefits may not outweigh the risks.
