Hearing aid technology has advanced significantly in recent decades. Still, at their heart, hearing aids have always had four fundamental components: a microphone, a processor, a receiver and a power supply. The microphone detects sounds in your environment and sends them to the CPU. The processor improves the signal and sends it to the receiver, which sends the amplified signal to the ear canal. The system is powered by a power source, known as the battery, says an expert of hearing machine in Kolkata.

Based on the sophistication of the processor, hearing aid technology can be classified as advanced or basic. Even the most basic digital hearing aids available today provide far more benefits than the best hearing aids of previous generations.

Hearing aid technology that is new and sophisticated

As technology advances, digital hearing aids become more automated and contain additional capabilities to assist you in communicating in tough listening conditions. New innovations result in more advantages. The characteristics listed below are more likely to be found in advanced hearing aids. 

Bluetooth connectivity

Bluetooth connectivity is a wireless capability that allows hearing aids to connect to mobile phones and other Bluetooth-enabled devices, usually via an intermediate device. Because the signal skips the microphone and reaches the hearing aid’s processor directly, Bluetooth technology can remove feedback from the microphone. Interference is also less common with a Bluetooth connection, says the expert of hearing aids in Kolkata.

Artificial intelligence (AI)

Some high-end hearing aids have artificial intelligence (AI), which allows them to analyze a sound using a deep neural network. Hearing aids can begin to make these modifications automatically when the sound is recognized by program preferences for specific sound environments. A DNN (deep neural network) allows hearing aids to begin to imitate how your brain would hear a sound if your hearing were normal.

Rechargeable batteries 

Hearing aids are increasingly being equipped with rechargeable batteries, which eliminate the need to replace small button batteries every few days or weeks, says the expert of hearing machine in Kolkata.

What are the practical advantages of these features?

Consider yourself at a regular crowded restaurant, enjoying dinner with pals. Dishes clanking, people talking and laughing at neighboring tables and waiters hurrying around create a cacophony of sounds. 

You’re wearing your new ear machines and listening to a conversation with a buddy across the table. She’s cracking a joke. Your hearing aids are simultaneously reducing impulse noises such as silverware clanging onto a plate (impulse noise reduction), decreasing the whir of the ventilation system above (digital noise reduction), suppressing the voices of people at tables behind you (directional microphone system) and storing information about the listening environment for later fine-tuning (data logging). 

They’re doing all of this automatically while boosting and modifying your friend’s voice signal. You may now relax and enjoy the punch line.
