Watching the progression of hearing aids over the years is nothing short of amazing. Today’s digital hearing aids are considered revolutionary, thanks to remote controls, Bluetooth connections and omnidirectional microphones. It’s been awhile since hearing impaired individuals in the 1800s only had the ear trumpet at their disposal when they wanted to amplify sound back in the 1800s. Fast forward many years later and digital hearing aids have revolutionized the way we hear. These devices underwent several models and prototypes until the ones we see today came out. With one eye on the future, audiologists can now customize each device depending on the requirements of each user, such as automatic adjustments on volume to ensure a comfortable level for the user. Taking out distracting background noise is another advantage, something that plagued users for many years.
The First Digital Hearing Aids
DSP is what makes digital hearing aids possible. They first were invented back in the mid-90s. Also referred to as digital signal processing, DSP allows users to benefit from higher processing speeds for improved hearing and farther range of amplification.
Digital noise reduction technology has surpassed that of multi-directional microphones, where it used to be that hearing devices were based on separation of speech to create speech modulation and other factors. However, today they are based on physical traits related to noise and speech.
Were you aware that digital hearing aids have the capability to regulate settings like volume? This is so individuals don’t have to set these factors every time they wear their devices. Added control for the user gives peace of mind.
In regards to improved connections, Bluetooth and other wireless technological services can further add to the overall listening experience. Three perks in particular include digital noise reduction, improved frequency transposition and increased range.
Single Sided Deafness
Used to be, if you were deaf on one side, you had to contend with background noise, which means you had to use your “good ear” to be able to hear and conduct conversations. Now, CROS devices and bone conduction devices make it possible to receive signals from the good ear and send them to the bad ear for sound amplification.
Looking ahead for hearing aid technology, the outlook for digital hearing aids is vastly superior because they are able to offer so many benefits to hearing impaired individuals. These benefits range from noise reduction to automatic volume setting adjustments, made possible by up to the minute wireless technology and microelectronics.
