Just How Do Hearing Aids Work?
By Mandy Fain
It's amazing that a device as small as a hearing aid can change a person's life as much as it does. Those of you who have had an experience of wearing a hearing aid must have wondered how it actually works, well they're pretty amazing things. Here we will discuss the basic working of different types of hearing aids that are currently available on the market.
All hearing aids have certain things in common, all hearing aids have the same basic components without these components, hearing aids would simply be unable to function. These components are: a microphone that picks up sounds around you, an electronic circuit that amplifies this sound and a receiver that transfers amplified sound to inner ear to be heard. The circuit works with the help of a battery, and all this equipment is housed within a small case which can fit in a variety of different places.
So, you see the hearing aid is simply a sound amplifier. That's how you are able to hear many sounds that you were previously unable to hear thanks to this advice. Hearing aids are split into two main categories, digital and analog. Analog aids are further divided into conventional and programmable aids. Programmable analog aids allow you to program specific functionality within the hearing aid to make it suitable for different environments, these settings can be changed by using a switch or a remote control.
Digital hearing aids work in much the same way as a programmable analog aid. The only difference is that these digital aids are self-adjusting. This means that the wearer doesn't have to change the volume or any other setting manually. Digital aids are characterized by the sampled analog signals as only high and low impulses. These signals are then manipulated by using techniques of digital signal processing to add extra features to the hearing device, including noise reduction, automatic gain control, compression and sound generation. Digital hearing aids are much more expensive than analog because of this extra functionality.
In addition to this classification, hearing aids are also distinguished on the basis of their style. Four popular styles are BTE (behind the ear), ITE (in the ear), ITC (in the canal) and CIC (completely in the canal). Their names pretty much explain where they all fit. Each type looks different and each are suitable for different degrees of hearing loss.
BTE hearing aids are composed of an ear mold that fits behind the ear, and tubing that transmits the sound to the ear. They are easy to use, easy to clean and easy to maintain. However, because of their size they are quite noticeable. These types of hearing aids are especially designed for kids because they may struggle to manage the other types of hearing aids. ITE hearing aids completely fit inside the ear and are barely visible. They usually come with extra functions like a telephone switch to allow the user to easily listen to a telephone conversation. ITC and CIC work in a similar way, but ITC aids are somewhat bigger in size than CIC hearing aids.
There is another type of hearing aid that is much less well known, this is called the bone conduction hearing aid. This is designed for people whose eardrum or ear canal becomes so damaged that other hearing aids are not feasible. The brain interprets these vibrations as sound. There is an additional component in this type of device, known as the oscillator, which receives sound signals and produces vibration according to their pattern. These aren't very common, they're only really used by people that have no alternative.
