Hearing Aids have become a part of our life and both analog and audifonos digitales are present today. If you are fascinated by it, then you will be glad to know that the science and the logics beyond these devices are just awesome and always improving for the benefit of people. Let’s dig in deeper!
We have both basic and advanced technology available to benefit the wearers. At the core, the aids consist of four basic parts – a microphone, power source, a receiver, and a processor. The whole process works by picking up the sound in the environment and passing it to the processor. The processor works back and forth to elevate and enhance the signal.
It finally delivers the signal to the receiver which then amplifies it and passes it to the output source (ear canal). The battery or the power source ensures the device is charged to complete this process after every step.
Virtually, most of the Headphones today are classified as digital devices due to the advancement of the technology. The signals picked up by the microphone is actually converted from analog to digital format and is finally converted back from digital to analog just before the enhanced signal is delivered to the ear canal.
Due to the strong efficiency of processing multiple signals and processing the sound effectively, these devices are now used in huge numbers as compared to their analog counterparts.
As programmers can implement different techniques in the processor, it is very easy to use these devices as it allows the hearing care experts and professionals to fine-tune the amplification power and traits to customize other special features as per the requirements and needs.
The doctor or the practitioners program the Hearing aids by connecting the devices to a computer and using special software implemented and provided by the hearing aid manufacturer. You can opt for aids as per the hearing aid style easily.
The most basic Headphones require manual adjustment to operating. Every single function like turning a volume control up or down or pushing the button on the aids needs to be carried out in person.
The processor also may separate incoming signals into two or more process and channels. A basic two-channel instrument may be also programmed to provide amplification for high-frequency sounds as compared to low-frequency sounds. Basic aids have limited adjustments that are available for fine-tuning to fit unusual patterns and are actually less customizable and cannot be automated.
The total number of channels actually represents the number of discrete sections that is used for processing many kinds of incoming sound signal. These aids can be easily customized across different frequencies and pitches. Regarding microphone, the noise and sound level is amplified and reduced on the basis of a different environment.
These microphones improve speech understanding and hence considered as a good source and option as compared to another type of hearing aids. Advanced systems like digital noise reduction systems analyze and determine if the signal needs to be amplified to reduce background noise for a crystal clear sound experience.
Impulse noise reduction based system improves listening comfort and helps to avoid sudden sound like car rattling, dishes rattling, or other instant noise and softens it quickly. Many experts claim that with the introduction of Feedback Management system reduce the whistling effect. These systems reduce or eliminate whistling without affecting the overall amplification of the hearing aid.
Interesting technology advancement is the introduction of Telecoil that picks up electromagnetic signals from the compatible telephones or the looped rooms. The technology is already available in the hearing aid for a significant and critical level to ensure the signal to noise ratio is improved and individuals can easily hear proper and accurate sound in Public performances, tours, exhibits and worship services.
Frequency modulation or FM compatibility is also a crucial factor and one of the important wireless features that enables hearing aids to connect through FM systems. It can be used alone or with the aids easily.
These systems are commonly used in educational and similar settings to ensure that the teacher’s voice can be easily heard without any issues. Regarding Bluetooth compatibility, it enables the aids to wireless connect to the mobile phones and other devices and improve the signal to noise ratio.
It also eliminates feedback because the signal bypasses the microphone and enters the processor. It is now possible that two digital hearing aids can communicate with each other through Binaural processing that helps the two aids to communicate with each other.
It can be used to keep the hearing aids operating in sync and send the signals from one to another easily. New aids have eight or more channels and offer a higher resolution of processing the signal.
In a nutshell, digital hearing aids are considered as one of the best aids to communicate effectively and are friendlier to a real-world scenario.
