Digital Hearing Aid Holds Advantages Over Analog
Many people often think that digital hearing aids will solve all of their hearing problems and it is this level of expectation that makes many hearing aid wearers disappointed with the overall product performance. When digital hearing aids were first introduced in the late 1980's, they were not well received due to their bulky size and intense battery usage. Additionally, many hearing aid clinicians were not happy with the devices' need to be programmed and though they were too complex for the average patient.
Today's digital hearing aids are much smaller and use very little power, but there is still the perception issue that just because an electronic device operates on a digital signal it must be better. This perception is due largely to the sound industry with everything from MP3 players to televisions with digital pictures. The push to move the public into the mainstream of digital imaging and sounds has increased the demand for digital hearing aids but also increased the expectations among new users.
The analog hearings, which have been around for many years, works on the simple theory of amplification. It takes a sound entering the unit's microphone and makes it louder when it enters the ear canal. Realistically, it is not the difference between analog and digital hearing aids that make such a big difference as it the ability to adjust the digital signal being processed.
Hearing Aid Programmable For Individual Users
When a person buys an analog hearing aid, their hearing is tested by a professional and the hearing aid is designed and programmed by the manufacturer. Either by software or engineering, the person fitting the hearing aid has some control over its final amplification ability, but digital hearing aids the basic controls are adjusted during the manufacturing process.
The biggest advantage to today's digital hearing aids is the ability to control the sound waves that are amplified. Many times hearing aid users complain about outside noises and background sounds interfering with their ability to understand speech. By clipping some of the digital audio signals, digital hearing aids can essentially block out sounds in a specific wavelength while amplifying sounds in others.
Realistically however, a person with damage to the sensory part of their brain that identifies sound or to the hair cells in the ear will not be helped by any type of hearing aid. It is unreasonable to expect any such aid, even digital hearing aids to provide the ability to hear when they brain cannot accept and interpret the sounds.
