Cochlear implants help individuals with severe to profound hearing loss perceive sound by directly stimulating the auditory nerve. Unlike traditional hearing aids, these devices can be powered down or removed. This article explores how to turn off a cochlear implant, common reasons for doing so, the resulting auditory experience, and daily device management.
How Cochlear Implants Can Be Turned Off
Cochlear implants consist of two main parts: an internal component surgically placed under the skin and an external sound processor worn outside the body. Users can turn off the external sound processor, which disengages the system. The internal implant requires signals from the external unit to function.
Turning off the sound processor is a simple process, often involving a dedicated button on the device. Some models allow users to press and hold a button until an indicator light confirms it’s off. Removing the external processor entirely also severs the connection. The external processor contains a microphone, a speech processor, and a transmitter coil that sends signals to the internal implant. When the processor is off, this signal pathway is interrupted, and no sound information reaches the auditory nerve.
Common Reasons for Turning Off an Implant
Users frequently turn off or remove their external sound processors for practical reasons. During sleep, the external unit can be uncomfortable and is not needed for auditory input. Protecting the device from water is another reason, requiring removal before activities like showering, bathing, or swimming.
Engaging in sports or other vigorous physical activities often necessitates removing the processor to prevent accidental damage or loss. Some individuals choose to turn off their implant when they desire quiet surroundings, such as for concentration or to reduce sensory input in noisy environments. This can provide a temporary respite from constant sound. Turning off the device also helps to conserve battery life, extending the operational time of the processor. Lastly, removal is necessary for routine maintenance, cleaning, or troubleshooting the external unit.
The Experience of an Implant Being Off
When the external sound processor of a cochlear implant is turned off or removed, the user no longer receives auditory input through the device. This means the world becomes silent or returns to the individual’s natural hearing level, which for many cochlear implant users is profound deafness. The internal component of the implant remains inactive without the external processor to convert sounds into electrical signals.
This cessation of sound input has clear implications for communication and environmental awareness. Without the implant active, verbal communication becomes challenging, often requiring visual cues like lip-reading or alternative communication methods. The user’s awareness of their surroundings is significantly reduced, as they cannot hear alarms, approaching vehicles, or conversations. Essentially, being “off” means returning to the quiet or profoundly deaf state that existed before the cochlear implant provided access to sound.
Daily Management of Your Implant
Proper daily management of a cochlear implant, particularly when it is not actively in use, helps maintain its performance and longevity. Battery management is an important aspect; users should regularly charge rechargeable batteries or replace disposable ones as needed. It is often recommended to turn the processor off before placing it in a drying unit overnight to remove moisture, which can extend the device’s lifespan.
When the external processor is not being worn, it should be stored in a safe, clean, and dry place, preferably in its designated case. This protects it from dust, accidental damage, and curious pets or children. Regular cleaning of the external components, such as the microphone and the main unit, with a soft, dry cloth is important to remove debris and maintain optimal function. Protecting the device from moisture and impact, even when off, is important for its continued reliability.
