The growth of digital hearing aids is amazing. While some digital devices are available with remote controls that allow the user to adjust various settings, others come with omni-directional microphones to detect sound from multiple directions. Most hearing aids manufactured today are digital and there are many reasons for that. Incredibly, it’s been about two centuries years since the first inventions that explored the science of personal sound amplification, with the introduction of ear trumpets in the early 1800s. One would think digital technology has been around longer than that, but not so. Now, these state of the art devices utilize the latest technology to provide filtration of background noise, connections to Bluetooth devices and provide automatic volume adjustment. Advancements have come fast and furious, progressing from analog to digital as we see it today.
With the influx of digital hearing aids, users can now utilize Bluetooth and other wireless technological services to make it easier to use the device. Users can also benefit from digital noise reduction, better frequency transposition, and increased range.
It’s possible for your digital hearing aid to learn on its own! Self-learning hearing aids are integral to modern devices because they have self-learning or regulating tendencies. Digital hearing aids are great for adjusting settings like volume automatically after a period of time according to how the user prefers it. Control is put into the hands of the person wearing it, which is yet another advancement.
Many manufacturers are implementing brand new technology through the use of digital magnetic wireless communication via chips in the devices that control settings like switch position and microphone modes. Today’s hearing aids can easily filter out that noise so that the user can hear words but not all the other stuff. Improvements in wireless technology have allowed for improved speech recognition and SNR, which stands for signal-to-noise ratio. Recent advancements mean hearing aids can actually communicate with each other, especially when it comes to left and right ear instruments. Many people says it’s hard to hear clearly with all the background noise, when using a hearing aid. Thankfully, the new digital ones can filter that noise easily.
Single Sided Deafness
Before the world saw all these big advancements in digital technology, individuals with single-sided deafness fell victim to greater background noise and were relegated to using their “good ear” to hear what was being said. Now, items like CROS devices and bone conduction devices, the good ear receives signals from the bad ear to improve on amplification.
Digital noise reduction technology surpasses that of directional microphones because it is based on the physical characteristics of noise and speech; on the flip side of the coin, they used to be based on the separation of space in terms of speech modulation.
For top-notch comfort and versatility, hearing impaired individuals can count on digital hearing aids to take advantage of innovative wireless technology and microelectronics to bring about more sophisticated abilities. The future for digital hearing aids is superior over other types, as the technology will only continue to grow as scientists make more discoveries.
