Digital technology, the latest know-how is now applied in the hearing aids too wherein the incoming sounds are converted into a computer code for further manoeuvring to make them more audible for the hearing aid users. More and more individuals now prefer to opt for these modern devices. The manufacturers are able to produce the digital hearing aids with superior features and methods through the digital signal processing, i.e. DSP. Available in all sizes as per the specific requirements of the wearers, the digital hearing aids are programmed by the qualified audiologists who care maximum for the clients through proper counselling and other requisite procedures. Digital hearing aids are advantageous in many ways.
Enhanced audibility – Proper processing and filtering of the incoming sounds through the digital hearing aids help in the improvement of the audibility and the wearer finds it comfortable to grasp the same with more clarity.DNR, i.e. Digital Noise Reduction – Unwanted noises in certain bands or the smaller frequencies are considerably reduced through the digital hearing aids.
Deafening sounds are cut down considerably that result in improved quality of the incoming speech. The users are delighted greatly in terms of relief from unwanted noises that could harm the ears in a big way.DFR, i.e. Digital Feedback Reduction – Feedback is monitored through the improved feedback reduction systems. The elimination process of the modest feedback is initiated by using the deletion structure or through scratch sifting. Feedback linked with the movement of the chin or nearness to any article is reduced through DFR.
DSP and Directional Microphones – Microphones are adjusted with DSP that helps to reshape the directional outline apart from automatic switching between Omni directional and directional modes. The surplus noise created with directional microphones is cut down greatly that helps the wearers to be relieved from the unwanted sounds.
Signal creation – With DSP, the digital hearing aids can create and process sounds. These contemporary devices that are fitted after proper hearing tests increase the loudness of the sounds. The levels of sound can be checked and unwanted backdrop sounds are eliminated that in turn help to enhance the speed signals.
Independent Programmability – While the incoming sounds are converted into computer code, the sounds can be broken into varied bands across different frequencies, i.e. from elevated to squat with the help of the computer chip inside the digital hearing aids. Such bands are programmed independently for improving the sound volumes as per the specific needs of the individuals who are satisfied with the digital hearing aids that help them to lead a normal life.
Volume control – With programming of the hearing aid, it is able to adjust the sound levels in an automatic manner. The computer chip processes a large number of sounds per second and amplifies the same across the frequency bands. The excessive volume for the relevant frequency segment of the noise is cut down without any effect upon the usual volume of the digital hearing aid that helps the user to grasp the incoming speech clearly.
