Streamers were available before the launch of Bluetooth hearing Aids. Streamers are interfacing devices that make a non-Bluetooth hearing aid function like a Bluetooth hearing aid.

Connect the television sets, music systems, or iPods to the Streaming device with a connecting cord. The streamers relay to a receiving device which in turn connects to the hearing aid. The transmitter and receiver technology are proprietary, a hearing aid of one brand cannot be used with a streamer of another brand.

Streamline from Signia (Originally Siemens Hearing Aids). Surflink Media from Starkey and TV Streamer 2 from Resound are some of the streamers.

2. Artificial Intelligence in Digital Hearing Aids

Changing batteries is a cumbersome routine. Senior citizens with unsteady hands are dependent on others for this. Inserting the small batteries in CIC and IIC hearing aid is difficult for a person of any age. The latest offering from the companies has a rechargeable hearing aid feature.

The Dutch company Widex has gone a step further and has announced a Fuel Mobile technology feature. Fuel mobile technology is the first in class digital hearing aid feature. As per the information released by Widex, this digital hearing aid does not require electricity. So, no searching for sockets to recharge if on the move.

The smallest commercially available fuel mobile fits into the digital hearing aid. A refill unit contains methanol. Methanol reacts with the air inside the fuel mobile to produce electric power. This 20 second process will supply power to the hearing aid for 24 hours.

6. Water Proof and Dust Proof

Water and electronics do not get along. All electronic devices need protection from water and dust. The humidity and dust damage the delicate miniature circuits inside the digital hearing aids. Exposure to water, humidity, and dust can lead to hearing aid malfunctioning.

Earlier, the manufacturers had a Nano coating on the hearing aid body. The coating made the hearing aid shell smooth and slippery. The water falling on the hearing aid rolls off and does not enter the gaps in the hearing aid body.

The manufacturers have now gone a step ahead, manufacturers are selling digital hearing aids which do not get damaged by water.

Digital hearing aids are now available with an IP rating. IP rating or Ingress Protection rating is an international quality standard. The number indicates the IP rating or the water and dust tolerance of the hearing aid.

  • IP67 or Ingress protection 67
  • IP68 or Ingress protection 68

Digital hearing aids marked as IP67 can resist water up to the depth of 1 meter for 30 minutes. IP67 also indicates 100% dust protection.

Similarly, IP68 can resist water up to the depth of 1 meter for 60 minutes. In case, you do not have waterproof hearing aids, read this blog on what to do if hearing aids get wet?

The listening programs of digital hearing aids are for different situations or surroundings. Normal settings are “Speech in noise”, for use when one is outdoors. “Speech in quiet”, when one is at home or in a silent environment. And “Telephone Mode”, when one wants to talk on the phone.

Digital hearing aids have a push button to enable the user to change the program. At times this is inconvenient as one has to struggle with tiny push buttons. Very small in the ear digital hearing aids do not have any buttons or control. One has to use a remote control to make changes.

The latest digital hearing aids automatically change the setting without the user having to do so. The built-in software detects the situation and does the needful. The setting of the hearing aid changes to telephone mode as soon as the phone is brought close to the hearing aid or the ear.

9. Invisible Digital Hearing Aids

There are vanity issues and stigma attached to the use of hearing aids. A hearing aid user thinks that he or she will be considered deaf or old if seen using hearing aids. Strangely, it’s not the same with spectacles. Our hearing ability and eyesight weaken with age. Users can now choose small invisible hearing aids which are practically invisible.

Please note that the digital hearing aids style or the type has to be carefully selected. The style of the hearing aid should be as per the user’s lifestyle. Select the size and shape of the hearing aid according to your lifestyle and budget.
