Nowadays, hearing aid types varies in their circuitry or technology. During the stone age, hearing aid technology involved vacuum tubes and large, heavy batteries. While in this highly digital age, microchips, computerization, and digitized sound processing are used in hearing aid design. However, you have to make sure that you chose a trusted audiologists in order for you to have an excellent hearing service.
Types of Hearing Aids
- Digital programmable
Generally, hearing aids have all the features of analog programmable aids but use digitized sound processing (DSP) to convert sound waves into digital signals. To simply determine whether the sound is noise or speech, a computer chip in the aid analyzes the signals. It then makes changes to produce a clear, amplified, distortion-free signal.
Usually, Digital hearing aids are self-adjusting. The sound it transmits matches your specific pattern of hearing loss given the fact that the digital processing allows for more flexibility in programming the aid. This kind of advanced hearing technology is the most expensive, but it offers many advantages. In which the key benefits are the following:
- There’s a management of loudness discomfort
- There’s improvement in programmability
- There’s control of acoustic feedback or whistling sounds
- There’s a noise reduction
- There’s a greater precision in fitting
Moreover, find the latest style of hearing aids that can store several programs. In which you can change the hearing aid settings as your listening environment changes. In fact, this can be usually done by pushing a button on the hearing aid or by using a remote control to switch channels. If your hearing or hearing needs change, then the aid can be reprogrammed by the audiologist. These aids can be more expensive than conventional analog hearing aids. Nevertheless, in different listening situations, this can still provide better hearing for you and the good thing is they generally have a longer lifespan.
- Conventional analog
Based on your audiogram, hearing aids are designed with a particular frequency response. Usually, the audiologist tells the manufacturer what settings to install. The aid essentially amplifies all sounds like speech and noise in the same way although there are some adjustments. This technology is the least expensive, and good thing is, it can be appropriate for many different types of hearing loss.
- Analog programmable
Most of the hearing aids have a microchip that allows the audiologist to program the aid for different listening environments. For instance, environments include quiet conversation in your home, noisy situations like a restaurant, or large areas like a theater. The programming settings vary on your individual hearing loss profile, speech understanding, and range of tolerance for louder sounds.
On the other hand, the clinic like in Pindrop they have hearing aids that have basic components that make them work while the sound processing involved in modern hearing aids. The basic function of a hearing aid are as follows:
- From the receiver, the signal is channeled into the ear canal, either through a small tube or through an ear mold.
- Sound waves enter through the microphone, which converts acoustic signals into electrical signals.
- A battery is required to power the hearing aid and enable the amplification process
- From the amplifier, the signal is then transformed back to an acoustic signal by the receiver (a miniature loudspeaker).
- The amplifier increases the strength of the electrical signal.
In finding a complete hearing aid services you have to make sure that you have chosen the right one. Since everything is highly digitalized still you need to see a professional when it comes to hearing condition.
