Digital Hearing Aid Definition

Digital on the other hand generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0. Thus, data transmitted or stored with digital technology is expressed as a string of 0's and 1's. Each of these state digits is referred to as a bit.

Rechargeable Hearing Aid Definition

Rechargeable hearing aids have built-in batteries that do not require regular removal, compared to hearing aids with traditional disposable batteries. Instead of removing the batteries themselves, you dock your hearing aids each night on a charging unit, similar to how smartphones recharge.

Digital Processing

A digital hearing aid is a hearing aid device that receives sound and digitizes it (breaks sound waves up into very small, discrete units) prior to amplification.

A digital hearing aid uses a microphone, but a microprocessor performs most of the device's functions digitally. Because the signal is represented as a series of numbers, it can be quickly and accurately altered.

Variations Of Digital Hearing Aids

• 1. Non Programmable or Trimmer digital hearing aid - which can not be programmed through computer. All standard setting done at the time of manufacturing.
• 2. Programmable digital hearing aid - programmed through computer- has number of features hence buying options differs-

Basic programmable hearing aid at low cost with minimum number of channel (2-4 channels) . Here hearing amplification and noise filtration option is minimal.

Standard programmable hearing aid at average cost with 6 to 16 channles digital processing. Here hearing amplification and noise filtration option is better than fewer channel.

Advance programmable hearing aid at high price with 24 channles and above digital processing. Here hearing amplification and noise filtration option is above than Standard programmable hearing aid.

Inside Signia Xperience: A Deeper Dive

Advantages of Digital Hearing Aids

• # Convert sound to digital signals.
• # Programmable and Non Programmable both types are available.
• # A digital hearing aid can be programmed to adjust itself to the current environment millions of times each second.
• # Can distinguish between noise and speech. Can suppress background noise so a person can hear speech better.
• # The most sophisticated digital hearing aids have built in intelligence that allows them to discern between soft, but desirable sounds, and louder, but unwanted noise.

Disadvantages of Digital Hearing Aids

• # Only disadvantage for non programmable non IP standard hearing aid is prone to damage to water, moist, dust etc!

Advantages of Rechargeable Hearing Aids

• # They don’t lose their charge.
• # No need to compromise on features.
• # Perform better on extreme environments.
• #Speed and convenience.
• # No need to charge batteries.
• # Environmentally friendly.
• # saves you buying or ordering batteries.
• # Only one battery needed.

Disadvantages of Rechargeable Hearing Aids

• # Higher initial cost
• # You need to remember to recharge your hearing aids.
• # More moving parts are involved.
• # Dependency on charger.
