What Do The Channels Mean On The Different Types Of Hearing Aids?

Thursday, January 4, 2018 12:43:27 PM Asia/Calcutta

Hearing Aid technologies have enhanced significantly over the last few of decades. Although all hearing aids essentially consists of four parts - a microphone, a power source, a processor and a receiver, yet different types of Hearing Aids offer different customized features. Indeed, even the present computerized hearing aid devices offer significantly more advantage than the best listening devices of past ages.

Based on the technology used, there are two types of hearing aids, namely Analog and Digital. While the Analog amplifies each and every sound signal that it receives, which is often annoying for the user. It is because, suppose the person using Analog hearing aids wants to listen only to the speech of the person that he/she is talking to in a noisy environment. But the person unfortunately cannot listen to the conversation properly due to the disturbing background noises being amplified equally by the device. However, the Digital hearing aids are much more technologically advanced, as they can determine your requirements and amplify only the speech by reducing background noise. This is a great advantage over the Analog ones. Today, most of the Digital types of hearing aids offer many more customized features and programmes that can be regulated by the user according to his/her needs based on the surrounding sound environment.

Different types of hearing aids, mostly the Digital ones, have different number of channels. The hearing aid channel is characterized by the scope of sound frequencies or the arrangement of advanced channels inside the listening device. The more the channels in different types of hearing aids, the more is the adaptability in programming, and more is the flexibility to control the different sound frequency ranges in the hearing aid. The quantity of channels speaks to the number of discrete segments that can be utilized for preparing diverse parts of the approaching sound signal. This customization of the listening device is called its frequency reaction.

To understand channels better, let us first discuss what bands are, and how are they different from these channels. Let us take a simple example by visualizing the distribution of water from the overhead tank. The tank distributes water to various lines or channels, which are then controlled by respective taps fitted at the end of every channel. These taps are like bands in different types of hearing aids, which control the flow of water (or sound frequency range). We adjust the taps according to our needs. If we do not need a heavy flow, then we naturally turn down the tap regulator, and vice versa. Similar is the case with the types of hearing aids, in which the channels are controlled or regulated by bands. In other words, the different sound frequencies received by different types of hearing aids can be controlled by regulating the bands as per the requirements of the user. There are many ranges of hearing loss in a person. If a person having no hearing loss in one frequency range and has severe to profound hearing loss in another frequency range, then he/she will adjust the bands accordingly, with absolutely reducing it or switching it off altogether (as required) at the first range, and making it higher at the second. Therefore, bands can be used to control the hearing frequency ranges as per the type and degree of hearing loss, and other hearing requirements of the user.

Before channels turned out, the listening device would just amplify all the sounds the same.

Inside the aid, there is a PC chip inside which has the ability to store multiple programs which can be customized according to different listening environment that the user may come across. The channels will do their part to conform to your hearing prerequisites naturally. They will work together to give you the correct level of volume that you will require for a perfect hearing experience.

 There are many types of hearing aids available at Hearing Plus, a reputable clinic that treats hearing impaired persons. They vary based on design (Behind-the-ear or BTE, mini-BTE, In-the-ear or ITE, In-the-canal or ITC, Completely-in-the-canal or CIC, Invisible-in-canal or IIC), technology used (analog and digital), features (directional microphone, direct audio input, T-coil, feedback suppression) and lifestyle of the patient. Some devices even have customized programs which can be self-regulated according to the specific needs of the user.

There are various benefits of hearing aid channels provided by different types of hearing aids, some of which are listed below :

  •  Adjustment

More channels imply that your device has more breathing space for modifications as per your hearing needs.

  • Condition

More channels imply that different types of hearing aids can perceive more sounds and hence distinguish different sounds all the more rapidly. The digital aids with various channels would thus be able to recognize and change settings for multiple conditions making way for a more agreeable and natural listening experience.

  • More Features

More channels frequently correspond with more features. Further developed functions and calculations can have a significant effect on the clearness of specific sounds.

  • Noise versus Discourse

Multiple channels implies that the different types of hearing aids are better ready to figure out which sounds are commotion and which sounds are discourse, empowering the listening device to reduce or even cancel-out undesirable sounds while amplifying the sounds you need to hear.

In the end, however, it depends totally upon you and obviously your Audiologist about your requirements and accordingly your audiologist will decide which device to opt for and how many channels you will really need. Whatever the case, you must have that satisfaction that you are getting what you expect and not restricting yourself on what different types of hearing aids have.

Choosing the Right Type of Hearing Aid Device

Saturday, December 23, 2017 6:08:55 PM Asia/Calcutta

Choosing the right type of hearing aid is a vital thing for hearing impaired persons. If the right type of hearing aid is not chosen, it may result in serious and even irreversible consequences for the user. You cannot wear any hearing aid on your own. Until and unless you are an experienced person in the profession of Audiologist, you should never even try to choose your hearing device yourself. It is strictly recommended that you should always consult a skilled and professional Audiologist before taking any decision.

The person suffering from hearing loss must make it a point to visit an experienced Audiologist as soon as possible, so that you get to know the exact type and degree of hearing loss. Different types of hearing aids serve different functions depending on the hearing of the patient. There are three broad types of hearing loss, namely, Conductive, Sensorineural and Mixed. However, these devices are used mainly to treat one of the major types of hearing loss, namely sensorineural hearing loss, which is caused due to disorders in the inner ear. Various types of hearing aids are prescribed based on the degree of hearing loss, which range from mild, moderate, moderately severe, severe to profound.

According to your hearing type, your Audiologist will help you choose the right hearing aid for you. Choosing the right types of hearing aids is as necessary as timely treatment. In either case, it may result in Auditory Deprivation, where the brain completely fails to perceive sound signals. This may further risk the chances of Dementia, a condition in which a person suffers from mental ailments like forgetfulness, mental instabilities, hallucinations and the like.

There are various types of hearing aids that serve different purposes according to the specific needs of the hearing impaired person. Today, there are so many manufacturers to choose from, each of them serving fascinating features and services, making people completely forget about their hearing impairment. However, different types of hearing aids have different particularities catering to the specific needs of the hearing impaired person. They vary in the features they offer, the technology used, the design and style of the device, the specific lifestyle of the user, and the price range they come in.

Based on the design of the device, types of hearing aids vary from behind-the-ear (BTE), mini-BTE, in-the-ear (ITE), in-the-canal (ITC), completely-in-the-canal (CIC), invisible-in-canal (IIC). As their names suggest, they come in convenient sizes that fit in the ear, and even inside the ear canal completely. Most hearing aid brands keep this flexibility in mind while bundling different types of hearing aids with different features, based on the requirements of hearing impaired people worldwide. Let’s have a brief glance at the individual features of the above devices.

The BTE or behind-the-ear type is widely used by people of all age groups, as it is usually compatible with any type of hearing loss. Also, it is capable of a greater amplification than other types of hearing aids. It has easy-to-use buttons that allows the user to flexibly regulate the device. The mini-BTE, on the other hand, are among those types of hearing aids that are barely visible, without compromising on the quality. This type also has a streamlined body and is usually preferred by persons having sloping hearing loss. The ITE or in-the-ear type is less visible than the above types as it fills the outer ear completely, and it is ideal for moderately severe hearing loss. The ITC or in-the-canal types of hearing aids are worn in the lower side of the outer ear and usually come with a longer battery life. The CIC or completely-in-the-canal devices lie hidden within the ear canal and amplify the natural hearing ability of the ear. These are suitable for moderate hearing loss. The IIC or invisible-in-canal types of hearing aids are very miniscule ones that sit deep inside the ear canal ana are equipped with powerful features.

Based on the technology used, there are of two types of hearing aids, namely, the Analog, which are microchip programmed and they amplify each and every sound, and the Digital, which convert sound waves to digital signals. However, digital hearing aids are more technologically advanced than the analog ones, and some types of hearing aids also offer many more features.

Based on the differences in features, most hearing devices are equipped with the directional microphone, the direct audio input, the T-coil or telephone switch, and the feedback suppression.

There are also certain types of hearing aids that come in unique features catering to the specific lifestyle of the user which vary from the simple, the social, the outdoor and the vibrant ones. These are again divided into various other types that serve the specific requirements and choices of the patients. Also, there is a special kind of listening device built into the stethoscopes of hearing impaired medical practitioners.

Now, that you know that there are such a great varietal types of hearing aids, the question arises, “Which is the right one for me?” There are certain parameters to keep in mind while choosing your hearing aid, of course on discussing with your Audiologist. Some such parameters are value for money, sound quality, performance, reliability, ease of fit and ease of use, customer support service, connectivity like bluetooth, Wi-Fi and other wireless technologies, durability, battery life, rechargeability, battery backup, and aesthetics. Different types of hearing aids are known for some specific features, so there are many options to choose from. However, you should always look for one that provides a really good overall service, and having good reviews, both from customers and Audiologists worldwide.

It should be always kept in mind that no hearing aid can replace the natural God-gifted ear, they can only help you in hearing better, which you were not able to before opting for a hearing aid. However, most of the types of hearing aids have the ability to amplify the original sound as natural as possible. Some advanced ones are so flexible and user-friendly that the user might completely forget that he is wearing one. The outcome produced by different types of hearing aids can be represented by three main dimensions, namely, the usage of the device, aided speech recognition and the benefits or advantages of the device. So, go ahead and explore which type suits you the best.

3 Types Of Hearing Loss

Tuesday, October 31, 2017 8:45:37 PM Asia/Calcutta

The three main section of the ear are termed as the outer, middle and inner ear. The types of hearing loss is generally identified by detecting which section of the hearing pathway is affected. The identification of the affected section in the ear is very important in the determination of hearing loss and hearing loss treatment. Scroll on to know the 3 types of hearing loss.

Conductive Hearing Loss:

Sound waves originating from any source are initially received by the outer ear. Then, it reaches the middle ear. When hearing loss occurs due to the problems in outer or middle ear, it is termed as conductive hearing loss. Such problems mean that the hearing is not conducted properly through the outer or middle ear. Hence, this type of hearing loss is termed as conductive hearing loss. Generally, this type of hearing loss may be cured with proper medication. If not cured with the help of medication or surgery, patients with such problems can be benefited from using a hearing aid, because sound amplification is what that they need the most.

Sensorineural Hearing Loss:

After sound is conducted through the outer or middle ear, it reaches inner ear

(innermost part of the ear). When there is a damage in any part of the inner ear or auditory nerve that connects the inner ear

to the brain, hearing is hugely affected. Such problems can be termed as sensorineural hearing loss. Hearing loss due to disorder in cochlea area of inner ear is of sensory type and if concerning nerve disorders, then it is known as neural. Together it is known as sensorineural hearing loss. It is the most common type of hearing loss.

Though it is a permanent problem, hearing restoration is absolutely possible with the help of hearing aids.

Mixed Hearing loss:

A combination of both conductive and sensorineural hearing loss (problems in both outer/middle and inner ear) is termed as mixed hearing loss. Sometimes, if conductive hearing loss is neglected and left untreated for a longer period, this type of hearing loss occurs. Hearing aids or other hearing devices can help in hearing restoration for most of the patients suffering from this type of hearing loss.

Other types:

Pre-lingual or before learning language/speaking

Post-lingual or after learning language/speaking

Congenital hearing loss or present at birth

Acquired or hearing loss after birth due to one/more reasons

Hearing loss in one ear is termed as unilateral hearing loss

Hearing loss in both ears is termed as bilateral hearing loss

Pure Tone Audiometry (PTA): How It Helps?

Tuesday, October 31, 2017 8:40:19 PM Asia/Calcutta

Do you know about Pure Tone Audiometry (PTA)? How much and what we hear both determine the quality of our lives in many ways. Hearing is an important part of the entire communication process. Yet we often take how much we hear for granted. However hearing loss may often lead to isolation, frustration and even depression. This is why we must always pay sufficient attention to our ability to hear. Since the time wasted on account of hearing loss going unnoticed and undetected in the initial stages, may often prove to be critical in its treatment. So always be alert to this rapidly growing problem of hearing loss. You must be pay sufficient attention to any initial symptoms of hearing loss and visit a good audiologist who can detect any hearing disorders through Hearing Tests. One such very important Hearing test is Pure Tone Audiometry. We at Hearing Plus being the experts about treatment of hearing loss would try to provide you some basic information about the important Hearing Test of Pure Tone Audiometry (PTA).

What is Pure Tone Audiometry (PTA)?

Pure Tone Audiometry is a hearing test which is conducted by the Audiologist to determine the threshold levels of the hearing of an individual. The Pure Tone Audiometry (PTA) is therefore a hearing test which helps the audiologist in gain an insight into the type and the degree of the hearing loss patient. This hearing test is a subjective test where in the participation of the hearing loss patient is necessary. His or her responses are recorded against stimuli during the hearing test.

What To Expect During The Pure Tone Audiometry  (PTA) Test?

During the PTA test the hearing loss patient is placed in a soundproof room. He or she is made to wear head phones. The Audiologist, who generally sits outside the room, controls certain audiometric equipment and first exposes the patient to various types of pitches. The audiologist then tries to analyze whether the patient responds these pitches. The patient is made to respond by raising the hand or pressing a button for the indication. The latter part of the PTA test involves testing of the bone and air conduction in the ears. Both the head phones and head band with oscillators is put behind the patient’s ears to conduct this part of the test. The audiologist tests the results for both type of the conduction and then analyzes which part of the ear is damaged and needs attention.

A typical PTA test normally takes about 20- 25 minutes to be completed. The results of the tests are recorded in an Hearing Test equipment called the “Audiogram”. However as mentioned earlier, since the PTA test is a subjective hearing test, the response of the patient is very important in determining the correct findings from the test. Following the test the audiologist decides on the future course of treatment and what type of hearing device if needed would be suit to raise the hearing levels.

One important point to note about the PTA testing is that the standard of the equipment as well as the competence of the audiologist is of paramount importance for the test. We at Hearingplus being experts in Hearing loss treatment too carry out the PTA test.  For further queries please visit www.hearingplus.in
