Digital Hearing Aids

The main distinction between analogue hearing aid and digital hearing aid is that the analogue introduced the conventional system in their method of conversion and digital introduced the new technology in their method of conversion. Analogue converts the sound waves into electrical waves while digital converts sound waves using accurate mathematical calculations which are processed by a computer.

Analogue Hearing Aids

• Analogue hearing aids cannot differentiate diverse sounds and therefore magnify all sounds uniformly that means some sounds are too loud while others may be very hard to hear. This problem is rectified when the user of hearing aid adjusts the volume.
• The programmable analogue hearing aids are prepared with different programs which are saved in the aid. The programs are then switched easily which are depending on the listening environment. For example, one program will work easily during a conversation while the other may work best as in the theatre.

Digital Hearing Aids

• Digital hearing aids convert the sound to digital code and then modify it and re-transmit it back by using mathematical calculations.
• Digital hearing aids duplicate the sound transmission very easily.
• A digital hearing aid produces a finest quality sound that is very accurate.

Many individuals consider that the digital system has revolutionized hearing by precisely duplicating sound transmission. There are many benefits of digital hearing aids and there are also lots of automatic features in digital hearing aids. Although some individuals still consider that programmable analogue aids possess great sound quality and functionality and this is also a great thing that analogue hearing aids are easily affordable.
