Analog hearing aids are the basic and simple hearing devices. They are made especially for people who are suffering from volume loss or hearing impairment. The analog hearing aids simply work to amplify sound with the aim to make it better audible for patients hard of hearing. You can adjust the analog hearing aids for basic settings like treble, bass and volume.
Now if you are planning to buy Analog hearing aids, you must consider reading this webpage as I am here peeping into the various aspects of Analog hearing aids.
There are basically 2 types of analog hearing aids: conventional analog hearing aids and programmable analog hearing aids.
The programmable analog hearing aids have a circuitry that admits more than one setting or program. Your audiologist will make use of computer to program the hearing instrument. When the hearing aid is fitted with the remote control device, the user can alter the program to adjust to any provided listening environment. This is to make considerably more alterations than controlled with basic analog hearing aids. The circuitry of programmable analog can be applied in all sorts of hearing aids.
The conventional analog hearing aids can amplify sounds using the electric analog circuit. These hearing devices can be found in television sets, typical stereo systems and public address systems.
The working of analog hearing aids
The analog hearing aids do not work with advanced type of signal processing ability. They do not have microcomputers on a chip like that of digital hearings aids, which has rather quite and sophisticated signal processing power. The analog hearing aids can amplify the soft sound more than the louder sounds.
Now, these analog hearing aids can compel the various lower and upper limit of loudness based on frequency. It can work to eliminate sounds that come from the second rear point microphone from the ones coming from standard forward points. This can make the conversation in the raucous environment much easy to follow and comprehend. The analog hearing aids can change their set of signal processing instruction on the base of the common mix of loudness and frequencies.
They are actually the old and cheap type of hearing aids and so is their working. Their amplifiers are inclined to have one linear frequency amplification curve for slight modification with tone controls. These tone controls are simply at the lower or upper ends of the range. Many times while using these aids, you might have to consent to the undesirable high amplification or loudness at upper end of spectrum.
Which one is better- digital or analog?
Analog is the basic technology, while digital belongs to an advanced range of hearing aids. There has been a long debate as to which hearing aids are better for hearing impaired people- digital hearing aids or the analog hearing aids? One cannot say that digital hearing aids are a distinct entity from the analog hearing aids. In the digital hearing aids, the analog wave form is transformed to a series of numbers for processing. The digital technology does have its own advantages. It just supports some advanced features and processing techniques.
So finally, your decision simply depends on the advice of your audiologist and your budget constraints.
