Hearing Devices

Hearing devices use different technologies to help people with hearing loss access sound. Some amplify sound through the ear canal, while others transmit sound through bone conduction or use implanted components to bypass certain parts of the auditory system. The New York Hearing Center offers several hearing technology options, including:

• Hearing aids: Devices that amplify and process sound according to an individual’s hearing needs.
• Bluetooth hearing aids: Hearing aids that can connect wirelessly to compatible smartphones and other electronic devices.
• Bone-anchored hearing aids: Devices that transmit sound through bone conduction to the inner ear.
• Earlens hearing technology: A specialized system that uses light-driven technology and a custom lens to stimulate the eardrum.
• Cochlear implants: Implantable electronic devices that bypass damaged sensory structures in the inner ear and stimulate the hearing nerve.
• Other implantable hearing devices: Specialized solutions that may be appropriate for selected types of hearing loss.

Each option has different benefits, limitations, and candidacy requirements. A professional hearing evaluation helps determine which technologies may be appropriate for your condition.

Hearing aids are electronic devices that amplify and process sound to help people with hearing loss hear more effectively. Modern digital hearing aids can be programmed according to an individual’s hearing test results and adjusted to support different listening environments.

Depending on the device, features may include directional microphones, background-noise management, rechargeable batteries, wireless connectivity, and smartphone controls. Hearing aids may help people who have difficulty following conversations, hearing television dialogue, understanding speech in groups, or communicating in noisy environments.

How They Work:

Hearing aids generally use microphones to capture sound, a digital processor to modify it, and a receiver to deliver the processed sound into the ear. The device is programmed to provide appropriate amplification based on the person’s hearing profile.

A hearing aid evaluation helps determine which device style, amplification level, and features may be suitable. Follow-up programming and adjustments can help improve comfort and listening performance.

Hearing aids do not restore normal hearing, and their benefits vary depending on the individual’s hearing loss and other factors. However, appropriately selected and fitted devices can improve access to speech and everyday sounds.

Bluetooth hearing aids combine hearing amplification with wireless connectivity. Compatible devices can connect to smartphones, tablets, computers, and selected television accessories to stream audio directly to the hearing aids. Depending on the model and device compatibility, Bluetooth features may allow you to:

• Hear phone calls through your hearing aids.
• Stream music, podcasts, and audiobooks.
• Listen to compatible television audio.
• Adjust settings through a smartphone application.
• Use supported wireless accessories.

Bluetooth connectivity can be especially helpful for people who frequently use smartphones or other electronic devices. However, connectivity features vary by manufacturer, hearing aid model, and operating system. When choosing Bluetooth hearing aids, it is important to consider both hearing performance and compatibility with the devices you use daily.

Bone-anchored hearing aids (BAHAs) use bone conduction to transmit sound vibrations to the inner ear, bypassing the outer or middle ear when appropriate. These devices may be considered for selected patients with conductive hearing loss, mixed hearing loss, or single-sided deafness. Suitability depends on the patient’s hearing profile, anatomy, medical history, and the specific device system.

How Do They Work:

Depending on the system, a sound processor captures sound and converts it into vibrations that travel through the skull to the inner ear. The inner ear then processes the sound through the auditory pathway. Bone-anchored hearing technology differs from conventional hearing aids because it does not rely solely on delivering amplified sound through the ear canal.

Some systems require surgical implantation, while other bone-conduction options use a non-surgical approach. A specialist can explain the differences and determine which options may be appropriate.

Earlens is a specialized hearing technology designed to deliver sound through a light-driven system rather than relying exclusively on the conventional acoustic receiver used in many hearing aids. The system uses an external processor to capture and process sound and a custom lens placed on the eardrum. Light-based signals activate the lens, which stimulates the eardrum and supports sound transmission.

Conventional hearing aids generally use a small receiver to deliver amplified sound into the ear. Earlens uses a different approach involving a custom eardrum lens and light-driven stimulation. Its potential suitability depends on the patient’s hearing loss, ear anatomy, medical history, and the system’s clinical requirements. It is not appropriate for every patient. A professional evaluation can help determine whether Earlens or another hearing technology is worth considering.

Cochlear implants are implantable electronic devices designed for certain people with significant sensorineural hearing loss who may not receive sufficient benefit from conventional hearing aids. Unlike hearing aids, which amplify sound, cochlear implants bypass damaged sensory structures in the inner ear and electrically stimulate the auditory nerve.

How Do Cochlear Implants Work?

A cochlear implant system typically includes an external microphone and sound processor, along with an implanted receiver and electrode array. The external components process sound and transmit signals to the implanted components, which stimulate the auditory nerve. The brain interprets these signals as sound. Outcomes vary, and cochlear implants require appropriate medical evaluation, programming, and rehabilitation.

Who May Benefit From a Cochlear Implant?

Some people may be candidates if they have significant hearing loss and receive limited benefit from appropriately fitted hearing aids. Candidacy depends on hearing test results, medical findings, speech understanding, and other individual factors. A cochlear implant evaluation helps determine whether this technology may be appropriate and what the treatment process involves.

Implantable hearing devices are specialized technologies designed to improve access to sound for selected patients whose hearing needs may not be adequately addressed by conventional hearing aids. Depending on the device, implantable systems may use bone conduction, mechanical stimulation, or electrical stimulation to deliver sound through an alternative pathway.

These devices differ in how they work, the conditions they treat, and their candidacy requirements. Some involve surgery and ongoing follow-up care. A specialist evaluation is important to determine whether an implantable hearing device offers a suitable alternative to conventional hearing aids or other treatment options.

Choosing a hearing device involves more than comparing features or prices. The appropriate technology depends on the underlying cause of hearing loss, the patient’s hearing test results, medical needs, and daily communication requirements. During the selection process, a hearing specialist may consider:

• Type of hearing loss: Conductive, sensorineural, or mixed hearing loss may require different approaches.
• Severity of hearing loss: The degree of hearing loss helps determine the level and type of support needed.
• Medical history and ear anatomy: Certain conditions may influence device selection.
• Previous hearing aid experience: The benefit received from existing devices can help guide future recommendations.
• Communication needs: Work, social activities, phone calls, and group conversations may influence useful device features.
• Connectivity requirements: Smartphone compatibility and wireless streaming may be important for some patients.
• Comfort and usability: Device style, maintenance, battery options, and ease of handling can affect everyday use.
• Treatment goals: Patients may prioritize speech understanding, awareness of environmental sounds, or specific listening situations.

Not every patient needs an implantable device, and not every patient benefits equally from conventional hearing aids. An individualized assessment helps identify appropriate options.

A hearing device evaluation helps determine which hearing technology may best address your needs. Your appointment may include a review of your hearing concerns, medical history, and previous treatment, along with appropriate hearing tests and discussion of your daily listening challenges.

Based on the findings, your provider can discuss suitable device options, explain their benefits and limitations, and recommend next steps. Depending on the device, care may involve fitting and programming, connectivity setup, surgical evaluation, device activation, or follow-up appointments. Some technologies also require rehabilitation to help patients adapt to new ways of hearing. The process is designed to help you make an informed decision about your hearing care.
