Digital hearing aids are the latest advancement for hearing impaired people. They use a digital circuit to analyze and process sound and are much less bulky than the older hearing aids we grew up with. A Digital hearing aid offers many advantages over their analog counterparts. They supply gain processing, which gives the user a greater hearing for sounds of interest versus background noises. You also get better digital feedback reduction, digital noise reduction, and digital speech enhancement
The main difference between analogue, the conventional system, and digital, the new technology, is in their method of conversion. Analogue converts sound waves to electrical waves while digital converts sound waves using exact mathematical calculations that are processed by a computer.
Many believe that the digital system has revolutionized hearing by accurately duplicating sound transmission. Digital hearing aids have many benefits and lots of automatic features.
Hearing aid devices work by magnifying the sound that is transmitted from your surroundings to your inner ear to improve your hearing capabilities. The majority of hearing aid manufacturers are eliminating the production of the old analog hearing aids. They have been replaced by digital hearing equipment.
According to the American Speech-Language-Hearing Association, there are at least 20 manufacturers of digital hearing aids that are sold under more than three dozen different model names. The digital processing of hearing aids involves the intricate management of signals. The technology consists of the use of a computer chip that translates external sound into digital code that can be evaluated and fine-tuned for each wearer. The signals are then transferred back into sound waves and transported to your ears.
Hearing aids today are digital, meaning incoming signals are converted into a series of numbers, which is then processed using mathematical equations. Digital processing enables very complex manipulation of signals, for example, to separate speech from noise. Many hearing aids today have more processing power than your desktop computer – gone are the days when hearing aids were simple amplifiers. Complex algorithms separate sound into different frequency regions and amplify each region selectively, depending on the wearer’s hearing loss. Algorithms also enable different amounts of amplification for soft, moderate, and loud sounds, so sounds are audible, but loud sounds are not uncomfortable or over amplified. And, digital processing ensures a precise replication of the original signal with minimal distortion, resulting in excellent sound quality for even the most discriminating audiophiles.

There are two types of Digital hearing aids :
Digital hearing aids which uses screw drivers to be programmed are low priced. There price/ cost ranges between Rs 6000 to Rs 10,000 (INR)
Digital hearing aid which uses computer to be programmed are high end digital hearing aids. There price / cost varies from Rs 10,000 to Rs 2,05,000 (INR)
The hearing aids come from the manufacturer un-programmed. We perform all programming in front of the patient, according to their hearing evaluation results and subjective preferences. When a hearing aid is purchased, all programming and follow-up appointments are included in the cost of the hearing aid. It is usually necessary to make several adjustments after the patient has worn the new hearing aids for a period of time – after the brain adjusts to the new sounds and the patient has been in a variety of listening situations. The most popular computer programmable digital hearing aids are:
|INFINITI Pro SP BTE – By Siemens||Rs 11490.00|
There are 4 classes into which you can divide digital hearing aids:
Economy Aids: An aid with digital circuits but not computer programmable. Analog-adjustable aids fit this class where an audiologist will determine the volume and other specifications and the manufacturer builds the unit. It will have limited ability to make adjustments however as far as hearing aid prices go, these are usually cheap hearing aids.
Improved Performance: These move to a computer programmable aid offering more flexibility and a customized fit. One of the basic features is multi-channel programming.
More Advanced: Aids that offer some automation and improved flexibility. They generally include the ability to automatically adjust to noise and a basic feedback reduction capability.
The Upper End: Premium hearing aids are typically fully automatic with programs that change to the sound environment. They can include speech enhancement features that add clarity in noisy situations.
