Hearing aids are not meant to be what your natural hearing powers were. It can never be so, just like how your correctional eyewear cannot be what natural vision was to you. It is meant to be a substitute for what you have lost. It can be, at best, a second choice. To be more blunt, a listening device cannot match up to what you could hear naturally. However, like it or not, you have to make do with it!
With technology, these hearing devices are closer to your natural hearing power than ever before. At our end in Bengal Speech, we sell cutting-edge devices that were not heard of even a couple of years back. Technology has actually jumped ahead in leaps and bounds!
The most basic problem with hearing aids is that you cannot hear everything that your natural hearing power could. Sound signals can come from any direction. It need not always be from a source directly in front of you or even from a source which is known to you. The direction can be from a single source or from multiple sources, like the chatter in a closed room.
This is the distinction between two kinds of hearing aids: the omni directional and the directional.
The omni directional hearing aid is able to pick up sound signals from any part of the ambiance. It need not always be from a desired or known direction. On the other hand, the directional hearing aid has its microphone cocked to one single sound source. It may be a speaker or a sound source in front or at the side known to you. Because it is coming from a single source, you are able to focus on it clearly and even hear it clearly.
Some directional hearing aid users will often tilt their head to one side, usually the direction of the source sound. This enables them to pick up sound signals more prominently.
Modern hearing aids, like the ones you can get from Bengal Speech, have both of these features incorporated in them. It is a happy balance where the device can pick up sound signals from different directions as well as a single point source. It ensures that you can hear things clearly, no matter how you are using the hearing machine or where you are located with respect to the sound source.
