When you discover that your child has been diagnosed with hearing loss, it’s natural to wonder what kind of hearing assistance they might need. Should you consider hearing aids or cochlear implants? Thanks to advancements in technology, even infants just a few weeks old can be fitted with devices to assist with their hearing. Your child’s pediatric audiologist will provide recommendations tailored to their specific level of hearing loss and individual requirements. To help you prepare for your upcoming consultation, let’s delve into the differences between these two types of hearing devices.
How Hearing Works
To grasp the distinction between hearing aids and cochlear implants, it’s essential to understand the basic function of the ear. Hearing loss is often thought of as an ear issue, but it fundamentally relates to how the brain processes sound. This means that both hearing aids and cochlear implants serve as pathways to the brain, enabling access to sound, meaning, and language necessary for a child to develop their listening and speaking skills.
The ear consists of an outer section and an ear canal that picks up sound, which is transmitted as acoustic energy. This energy travels through the middle ear to the cochlea. The cochlea’s role is to convert this acoustic energy into electrical signals. Inside the cochlea are tiny hair cells that help propagate the sound and facilitate this conversion. In a healthy ear, these electrical signals travel to the brain, allowing for sound perception.
Hearing Aids vs. Cochlear Implants
Hearing aids amplify sound. They are suitable for children who have some residual hearing but need assistance in making sounds louder. They work by increasing the volume of sounds, which the child’s existing ear structures can process.
On the other hand, cochlear implants are more complex devices designed for children with severe to profound hearing loss. They bypass damaged parts of the ear and directly stimulate the auditory nerve, sending signals to the brain. This approach is especially beneficial for children who cannot benefit from hearing aids alone.
