Слуховые аппараты, классификация

Слуховые аппараты, классификация

Те или иные проблемы со слухом испытывают достаточно много людей. Частичная или полная глухота может быть как врожденным, так и приобретенным явлением, поэтому от развития этого недуга (например, в результате травмы), не застрахован, увы, никто.

К счастью, современные технологии готовы прийти на выручку слабослышащим людям и помочь им справиться с дискомфортом в повседневной жизни. Для этого существуют особые электроакустические приборы, называемые слуховыми аппаратами.

Современный рынок буквально изобилует различными типами этих устройств. Слуховые аппараты различают по:

  • способу обработки звукового сигнала;
  • методу настройки;
  • способу закрепления на ухе.

Кроме того, в зависимости от способа обработки поступающего звукового сигнала, выделяют цифровые и аналоговые устройства для слабослышащих. Аналоговые приборы усиливают все окружающие звуки, довольно просты в эксплуатации и весьма доступны.

К недостаткам таких аппаратов стоит отнести тот факт, что они усиливают звуки не избирательно. Во многих случаях это может быть источником серьезного дискомфорта, поскольку окружающие шумы слышны так же хорошо, как и человеческая речь.

С цифровыми приборами подобных проблем не возникает, поскольку они способны снижать уровень посторонних шумов и более качественно передавать звуки речи.

В зависимости от того, как какому из вышеописанных типов принадлежит аппарат, его настройка может осуществляться либо программными методами, либо вручную.

В зависимости от применяемого способа крепления на ухе слабослышащего, выделяют:

Заушные аппараты – держаться непосредственно за счет ушной раковины. Соединение аппарата с находящимся в слуховом проходе вкладышем осуществляется посредством специальной трубки. Устройства этого типа отличаются демократичной стоимостью и пользуются наибольшей популярностью у покупателей и специалистов.

Внутриушные слуховые аппараты – вводятся непосредственно в ушную раковину. Обычно изготавливаются по индивидуальному заказу, с соблюдением всех анатомических особенностей уха конкретного пациента. Применяются только в случаях незначительного расстройства слуха. Отличаются миниатюрными габаритами.

Также существуют аппараты, довольно больших размеров, которые обычно носят в кармане. Чаще всего их используют люди преклонного возраста.

          Hello this is kind of of off topic but I was wondering if blogs use WYSIWYG
          editors or if you have to manually code with HTML.
          I’m starting a blog soon but have no coding knowledge so I wanted to get guidance
          from someone with experience. Any help would be greatly appreciated!

            Hi, I do believe your web site could possibly be
            having browser compatibility issues. Whenever I take a look
            at your blog in Safari, it looks fine but when opening in IE, it has
            some overlapping issues. I merely wanted to provide you with a quick heads up!
            Besides that, great site!

                      You actually make it seem so easy with your presentation but I find this matter to be really something that I think
                      I would never understand. It seems too complex and
                      extremely broad for me. I’m looking forward for your next post,
                      I will try to get the hang of it!
