Hearing aids — clear sound transmission

Thanks to modern technology, a person with hearing problems can hear, communicate, be active, successful and feel comfortable in everyday activities. Hearing aids help to correct varying degrees of hearing loss and amplify sounds at certain frequencies. Small devices are installed on one or two ears for better delivery of sound signals to the brain. 

Features of a hearing aid

Each hearing aid for restoring hearing function has three main elements:

  1. Microphone — turns sound from sound waves into a signal.

  2. Amplifier — provides sound processing, amplifies the signal.

  3. Telephone (receiver, speaker) — receives the amplified electronic signal, delivers it to the ear.

After the sound reaches the cochlea, hair cells convert it into a neural signal and transmit it to the brain. 

Types of hearing aids

Before choosing a hearing aid, it is important to analyze its features. The device is capable of processing electrical signals in analog or digital form. Analog models provide the original type of sound transmission. Devices of this type transmit a signal from one element to another without changing its shape. The sound waves received by the microphone remain the same when transmitted by hair cells. Sound is electronic and amplified.

Most modern hearing aids are digital. The device takes a signal from a microphone and turns it into binary code before it enters an amplifier. Digital transmission can include information about the original sound. It allows you to detect errors. Hearing aids can be programmed for specific tones. Thanks to these features, the devices can be customized to meet individual needs. This is an excellent option in case of uneven hearing loss at all frequencies. All types of systems have a number of advantages:

  • clear hearing of the person you are talking to;

  • ease of use;

  • excellent reproduction;

  • compactness and invisibility;

  • wireless functionality;

  • additional features.

Hearing aids are divided into behind-the-ear and in-the-ear hearing aids. Behind-the-ear (BTE) devices are more common and versatile. In-the-ear devices are placed in the ear canal and are made to fit an individual ear mold.

FAQ

What is a hearing aid and for whom is it intended?

A hearing aid is a modern medical device designed for adults and children with persistent forms of hearing impairment.  The device helps to perceive the sounds around you at the appropriate level.  

What types of hearing aids are there?

Hearing aids are divided into 2 categories:

  1. BTE devices have a housing behind the ear, fit almost all users, and are capable of correcting mild to profound hearing impairment.

  2. In-the-ear models are located in the ear canal, hard to spot, but not suitable for all people.

In order to find the optimal model of device, it is necessary to consult a hearing care professional.

How do hearing aids work?

A hearing aid receives sound through a microphone, which is converted into electrical impulses. Then they are sent to an amplifier, which increases the power of the signals. The signal is then transmitted to the auditory canal via a receiver.

How do I choose the right hearing aid?

Before you buy a hearing aid, you should be examined by a surgeon. The specialist takes into account:

  • the degree of hearing loss;

  • the range of frequencies that need to be corrected;

  • individual characteristics;

  • the presence of concomitant diseases. 

Based on the diagnostic results, the doctor determines the tactics of hearing correction and gives recommendations for choosing a hearing aid model. 

Hearing aid care

For reliable functioning of the hearing aid and a long service term it is necessary to follow the care recommendations:

  1. Wipe it with a dry, clean cloth daily.

  2. Use the MultiTool universal tool if necessary.

  3. Remove the hearing instruments before going to bed by opening the battery compartments.

  4. Store the units in the case away from heat sources, children and animals.

  5. Remove the device during heavy rain, when using a hairdryer or in the swimming pool.

It is important to make sure that moisture does not form inside the hearing aid and to protect it from bumps and falls.
