    What’s Inside your Hearing Aid?

    Today's hearing aids had come a long, long way since
    its invention in the 17th century. Modern hearing aids come with
    sophisticated technology that makes it nothing short of a scientific marvel.
    And, not to forget, it helps millions of people hear and enjoy life

    If you're a hearing aid user or contemplating using one, it's a great idea to understand the basics of what's inside it and how it works. It not only helps you appreciate these marvelous technological inventions but also enables you to troubleshoot it if any errors occur.

    Hearing aids are of two major types:

    • RITE (Receiver-in-the-ear)
      hearing aid
    • FITE (Fully-in-the-ear)
      hearing aid

    Regardless of the hearing aid you use, it contains the
    following three major components.

    • The Microphone

    The functioning of the hearing aid starts with the
    microphone. It picks up the various sounds from the environment and converts it
    into electric signals that are fed to the processor.

    When you buy hearing aids, look for advanced models that can differentiate between different sounds helping to separate background noise from speech. These models segregate sounds into various categories, processing them differently, thereby providing the wearer with a better hearing experience.

    Microphones can be further classified into two types:

    • Directional microphones – As the name implies, this picks up sounds predominately from one direction, i.e., sounds coming in from the front of the wearer. Directional microphones are great when the user wants to recognize and understand speech in a noisy place. To give an example, the Siemens Signia Pure Primax model makes use of directional microphones. Make sure to check out the latest Siemens hearing aid prices before you choose the right model that works for you.
    • Omni-directional microphones – From the name, you would have guessed it. These microphones pick up sounds from all directions. It helps the user orient them better in a noisy environment.

    Nearly all modern hearing aids have both these types
    of microphones to provide users with a more natural listening experience.

    • The Processor

    It's also known as the amplifier. It's the small chip
    that acts as the brain of the hearing aid. It converts the electric signals
    picked up by the microphone into digital signals. The microprocessor decides
    how the digital signal has to be amplified based on the wearer's needs. The
    severity of the user's hearing loss determines the amplification levels.

    To give an example, if the person has low to moderate
    hearing loss, then the signals are amplified only a little. The power of
    amplification depends on the hearing capabilities of the wearer. This is why
    swapping or exchanging hearing aids with another wearer is not recommended.

    The processor also cuts down other distracting sounds
    in the environment like wind, background noises, etc. Once the processor has
    optimized the sounds picked, it converts the signal – from digital to analog,
    which goes to the next component.

    • The Receiver

    Also known as the speaker, this is the final component
    of the hearing aid. The primary role of a hearing aid is to deliver sounds from
    the environment directly to your ear. And, the receiver does that. It
    transforms the electric signals from the processor into sound waves that are
    passed into the wearer's inner ear.

    The position of the receiver depends on the severity
    of the hearing loss and lifestyle preferences. In some hearing aids, the
    speaker is placed directly into the ear canal. While in other models - the
    receiver is connected to a small tube inserted into the ear.

    Apart from these three major components, hearing aids
    have other minor but equally important parts like:

    • Battery – This is the power
      source for all the parts of the hearing aid.
    • Volume Control – This helps
      the wearer to increase or decrease the intensity of the sound. It may not be
      present in all styles.
    • Wax guard – This prevents ear
      wax from clogging the critical components of the hearing aid.

    Understanding the components of your hearing aid will help you make informed choices while comparing different hearing aids for sale. Make sure to learn the features of your hearing aid, to pick the right one that suits your medical requirements as well as your lifestyle preferences.
