When you are eager to hear all the sounds around you and fail to do so successfully, it may not agree with you. There are solutions for these problems, and they are hearing aids. As the name suggests, these are machines that can help you understand the sounds in a better and more pronounced way. There were analog hearing aids till now, but now you will also get digital aids for hearing all the sounds more clearly like never before. These machines consist of some components that will process the sounds for you, and you can listen to the sounds true to life.
Analog hearing aids
The analog hearing aids, unlike the digital hearing aids Washington, make the sounds louder and it amplifies all the sounds – like the noise and the speech too. Some analog machines are programmable, and it contains a microchip. The programs are stored here, and the settings can be chosen for different listening environments. You can use these settings and change the situation in a quiet setting like a library or to a noisy place like a restaurant. There are settings of amplified ambiance too – like a football stadium or a movie hall. The settings can be changed from one to another with a single push in the machine.
Amplify all the sounds
These machines help in hearing when you have a low hearing capacity. They will cost less and can still be more powerful than the digital ones at times. These machines process the sound simply or straightforwardly. The microphone picks up the music and then amplifies it. Then the music is sent to the ear through some efficient speaker machine. This machine amplifies all the sounds, and so you get the actual sound of a voice with the unwanted background sounds. You would want to hear the voice or the speech but would like to keep the background noise at a low level.
Digital hearing aid
These are also named digital signal processor. These machines are also programmable ones, and they can be changed too. The main difference is that these machines convert the sounds to digital signals. The digital signals are duplicates of the sounds. So there is conversion to digital signals and not an amplification of sound. The machine has chips that are used for analyzing the speech with all the available sounds. This helps in the processing of the sounds instead of amplification. This helps in reducing the background noise to some extent. The programs are set flexibly so that the ones who have lost the hearing ability get more advantage.
Reduced background noise
These machines, therefore, are versatile and can amplify the sounds that are specified by the program. These sounds are then converted to digital signals and then stored at a specific frequency in the computer chip. The digital hearing aids Washington, therefore, save the higher frequency sound of the voice in a separate place, and the lower ones or the background noise are stored in a different area. The hearing aid is programmed so that the computer chip amplifies the high-frequency sounds and suppresses the low-frequency ones. This makes it easy for the user to hear the speech or voice and get the background sound almost filtered by the machine. The one who is low on the hearing will find it easy now to follow any conversation and get the noisy environment reduced for his betterment.
