Though there are several types of hearing aids, the digital hearing aids are deemed the best in terms of reliability and efficiency. This is because of the quality of sound that comes from them. Today, more and more people with hearing difficulties have been gravitated towards digital hearing aids and have neglected the analog hearing aids.
Perhaps it’s due to the numerous advantages that digital hearing aids have over analog hearing aids. For the sake of this article, I am going to talk about the advantages of digital hearing aids. However, before we go into details about the advantages of these devices, let us first know the difference between analog and digital hearing aids.
Analog hearing aids generally takes and amplifies sound as it is without making any modification on the sound, just in a similar way cupping your hands behind your hear amplifies sound. Digital hearing aids, on the other hand, take in sound waves, translate them to a digital format, distort, filter, amplify, and finally deliver them to the ear canal, tailored according to your needs.
Digital hearing aids have a special chip known as digital signal processer that enable them to perform all these functions. Now that you have known the difference between analog and digital hearing aids, let us now look at the advantages of these devices.
They are small in Size Compared to Analog Hearing Aids
Generally, digital hearing aids are very small in size compared to their analog counterparts. They can be placed behind the ear without other people noticing. This means that the person using these devices will not be embarrassed in knowing that other people know about his or her deafness. This is the greatest advantage of digital hearing aids.
Improved Speech and Noise Filtering
Digital hearing aids are incredible multitaskers. Despite their small size, these devices can perform different sound processing tasks. In one function, the digital hearing aid is capable of differentiating between speech-sounds and noise and as such amplify the speech while reducing the noise at the same time. In analog hearing aids, the sound is amplified less discriminately, hence a lot of noise can get its way through a meaningful conversation.
They Can Be Specially Designed to Fit an Individual’s Needs
Digital hearing aids can be programmed using a special software to suit your hearing needs. Though analog hearing aids can also be programmed in a way, digital technology offers a far much greater degree of sound processing and fine-tuning. A better programming in digital hearing aids means ability to adapt in different sound environment. For instance from a quiet library to a noisy club or restaurant.
They are More Comfortable
One of the greatest disadvantage of analog hearing aids is the discomfort that comes from the noisy sounds. However, using the digital signal processor in digital hearing aids, the noise is reduced significantly. This is because digital hearing aids have specific input signal dependence band, many channels, and knee pints that lower the compression threshold. This helps to reduce the intensity of environmental sounds as well as noise from the microphone that makes most users of analog hearing aids uncomfortable.
Digital Feedback Reduction
Digital hearing aids have feedback reduction systems that are so advanced that they can monitor feedback while the user is wearing the device. When this happens, moderate feedback is cut down through a cancellation filter in the device. People who bother the users when they are close to them or during jaw movement can benefit from this feature in digital hearing aids.
Digital Speech Enhancement
Digital speech enhancement technology was recently introduced to digital hearing aids, making it effective in intensifying specific segments of speech, making it a better device that the analog hearing aids. However, more studies are still being done on this feature to establish how effective it can be when it comes to enhancing speech.
Eye-Catching Designs and Color
Unlike analog hearing aids, most digital hearing aids have more eye-catching designs and colors such that most people mistake them for phone Bluetooth. Their design and colors make it less embarrassing to the users since most people cannot tell what they are. Most hearing aid users feel embarrassed when they realize that other people know about their hearing disabilities.
The beautiful designs and colors of these devices, therefore, helps in hiding their embarrassment since most people mistake them for communication devices. Not too long, the use of digital hearing aids will completely replace analog hearing aids. However, this may not be possible until the price for digital hearing aids are lowered. But who knows? People can as well decide to embrace the new technology over the analog given the several advantages it comes with.
