How a Hearing Instrument Works

  All hearing instruments are not created equal. However they have certain basic things in common. A simple explanation is that they let you hear sounds that you are missing. In short they will help you hear better and the most advanced ones will help you hear as naturally as possible.  
     
  These are the basic components:  
     
  1.  Two microphones to pick up sound  
  2.  A digital amplifier to make the sound louder and adjusted to your prescription  
  3.  A miniature loudspeaker called a receiver that sends the amplified sound into the ear for you to hear  
  4.  A tip or mold that goes into the ear, or an individual shell for custom instruments  
  5.  A tiny battery that runs the instrument  
       
  How to know what’s right for you?  
     
  Choosing your hearing instrument is the first step to success. There are 3 basic elements to this decision:  
       
  1.  Your design and style preferences  
  2.  Your communication needs and hearing abilities  
  3.  Other individual preferences and issues, including financial matters  
     
  You are going to make this decision with expert advice. It is important to share your needs and preferences with your hearing care professional, and together you will arrive at a solution that is best for you. Hearing care professionals are accustomed to guiding this discussion and will help you make the right choice.  
     
  Design and Style  
  People have preferences about how hearing instruments should look, feel and operate. These preferences are often the first things people think about when they decide to purchase a hearing solution. How a hearing instrument looks can be a very important decision factor, especially if you are a first-time wearer. But even an experienced wearer wants an attractive solution. Huge strides are being made in hearing instrument design. Hearing instrument manufacturers and hearing care professionals have been listening to the public. The result: choices that satisfy people more than ever before.  
     
     

Choose Your Style
         
         
  Receiver-In-the-Ear (RITE)      
  All RITE solution have their electronics, battery, and microphone inside a casing worn behind the ear. An ultra thin, sculpted wire carries the amplified sound to a speaker that fits in the ear canal. RITE advantages include- superior cosmetics, a more natural sound quality and a comfortable open fitting. Initially introduced for mild hearing losses, RITE is becoming increasingly popular for moderate and severe hearing loss, as well. RITE solutions are available in different sizes. Improvements in microchip design can explain the high popularity of the ultra small miniRITE solutions which are more effective than ever.  
         
  BTE with Earhook      
  BTEs with earhooks are connected to the ear canal via plastic tubing. The tubing is attached to an ear mold which is custom made from an ear impression to perfectly replicate the size and shape of your ear. Most BTEs with earhooks can be fitted with a very cosmetically appealing thin tube solution. For some people, the BTE is a better solution due to hearing needs, dexterity or physical fit. It is still the most widely used choice for children and people with high power needs.    
       
  Both styles of BTE solutions are available in a range of natural colors to match peoples’ hair or skin tone and in more creative colors to match their personal style. Children are especially interested in bright, fun colors, which capture their imagination and help them feel positive about their choice.    
         
  Custom      
  Custom hearing instruments range in size from the smallest CIC (Completely-In-Canal) to the slightly larger ITC (In-The-Canal) to the HS/ITE(Half-shell or In-The-Ear). All of the working parts are contained within a single unit which is custom molded to the ear. A choice of colors is available to best match individual skin tone.    
   
       
  Custom styles can usually be vented, to permit air exchange from the environment to the ear canal. However, people with smaller ears and milder hearing loss may find the venting insufficient, and may prefer a more open BTE style.    
         
  If the smallest CIC is right for you, it can be quite cosmetic. However, the larger custom products are usually more flexible for people with more significant hearing loss, and can be easier for some people to insert. Many wearers now prefer the RITE solutions over custom products due to cosmetic appeal and other acoustic advantages.    
       
  Whether you prefer a RITE style with a non-traditional design, a BTE with ear-hook or a custom version, there are a wide variety of choices available. It is important that you communicate your preferences to your hearing care professional.
