Bone Conduction Hearing Devices

About BCHD

Components: they consist of two main components, an internal component which will be beneath the skin in the bone and external sound processor which will be worn over the skin.

Here's how BCHD works

Implantation: BCHD consists of two main components: a small titanium implant and an external sound processor. The implant is surgically placed into the bone behind the ear during a minor outpatient procedure. Over time, the implant fuses with the bone in a process called osseointegration, providing a stable anchor for the external components.

Sound Transmission: The external sound processor captures sounds from the environment using a microphone. Instead of transmitting sound through the ear canal, the sound processor converts the acoustic signals into mechanical vibrations.
Bone Conduction: These vibrations are then transmitted through the skin and skull bone to the implanted titanium fixture. The implant vibrates in response to sound. This bypasses any obstructions in the outer or middle ear, allowing individuals with certain types of hearing loss to perceive sound more clearly.

Who Is It For?

  • Have conductive hearing loss due to conditions such as chronic ear infections, congenital malformations, or middle ear surgery.
  • Experience mixed hearing loss, which involves a combination of conductive and sensorineural hearing loss.
  • Suffer from single-sided deafness, where one ear has little to no hearing function, while the other ear has normal or near-normal hearing.
  • BCHD systems come in various models and configurations to suit different hearing needs and preferences. They are custom-fitted and tailored to each individual’s unique anatomy and hearing profile.

Project Name :
Hearing Aids

What is it?

Hearing aids are small electronic devices designed to improve hearing for individuals with hearing loss. They work by amplifying sounds from the environment and delivering them to the ear, making them easier to hear and understand. Here’s how hearing aids typically work:

Microphones: Hearing aids contain one or more microphones that pick up sounds from the surrounding environment.
Amplifier: The microphone sends the incoming sounds to an amplifier, which increases the volume of the sounds.
Signal Processing: Advanced digital hearing aids often have signal processing technology that helps to filter out background noise, enhance speech clarity, and customize the sound to match the wearer’s hearing needs.
Receiver: The amplified sounds are then sent to a receiver or speaker, which delivers the sound into the ear canal.
Ear Mold or Dome: Depending on the style of the hearing aid, the sound is delivered either through a custom ear mold that fits snugly into the ear canal or through a small dome that sits in the ear canal.
Battery: Hearing aids are powered by batteries, which can be disposable or rechargeable. The batteries provide the necessary energy for the hearing aids to function.

Types of Hearing Aids

Hearing aids come in various styles and sizes to accommodate different types and degrees of hearing loss, as well as personal preferences. Common styles include:
Behind-the-ear (BTE): A small device that sits behind the ear and is connected to a custom ear mold.
Receiver-in-the-ear (RITE) or receiver-in-canal (RIC): Similar to BTE, but the receiver or speaker is placed inside the ear canal, connected to the device by a thin wire.
Completely-in-the-canal (CIC): The smallest type of hearing aid, fitting completely inside the ear canal and nearly invisible when worn.

Project Name :
Cochlear Implants

Cochlear Implants

Cochlear implants are advanced medical devices designed to provide a sense of sound to individuals with severe to profound hearing loss or deafness. Unlike hearing aids, which amplify sounds, cochlear implants bypass damaged parts of the inner ear (cochlea) and directly stimulate the auditory nerve, allowing the wearer to perceive sound signals.

Cochlear Evaluation

Cochlear implants can provide significant benefits for individuals with severe to profound hearing loss who do not benefit sufficiently from hearing aids. They can help improve speech understanding, communication skills, and overall quality of life.

It’s important to note that cochlear implants require a comprehensive evaluation by a team of hearing healthcare professionals, including audiologists, otolaryngologists (ENT specialists), and speech-language pathologists. The evaluation helps determine candidacy for cochlear implantation and ensures that individuals receive appropriate counseling, support, and rehabilitation services before and after surgery.

External Components: Cochlear implants consist of two main components: an external sound processor and an internal implant. The external sound processor captures sounds from the environment using microphones and processes them into digital signals.

Speech Processor: The digital signals are then transmitted to a speech processor, which filters and codes the signals based on their pitch and intensity. This processed information is sent to a transmitter coil in the external component.

Transmitter Coil: The transmitter coil transmits the coded signals wirelessly across the skin to an internal receiver-stimulator, which is surgically implanted beneath the skin behind the ear.

Electrode Array: The receiver-stimulator converts the coded signals into electrical impulses and sends them along a thin electrode array, which is inserted into the cochlea during the surgical procedure.

Auditory Nerve Stimulation: The electrical impulses stimulate the auditory nerve fibers in the cochlea, bypassing damaged hair cells and directly activating the nerve fibers. These signals are then transmitted to the brain, where they are interpreted as sound.
