Advancements in Cochlear Implant Technology
In recent years, technology has become available that has allowed hearing aid users to connect their hearing devices directly to their Apple IPhone. This technology has allowed users to stream phone calls, stream media, and use their phone as a remote control without the need for an extra piece of equipment (neck worn device, etc.). Unfortunately, this option has not been available for cochlear implant users. However, with the release of Cochlear Americas’ Nucleus 7 sound processor, this is now a great option for IPhone and Cochlear Americas implant users.
But what about users without iPhones?!
Not to worry, there are still those “in-between” devices that will allow users to connect to their cell phones with Bluetooth. These types of devices are available to users of all three of the cochlear implant companies with which we work (Advanced Bionics, Cochlear Americas, and MED-EL).
If you or a loved one are a cochlear implant user looking to upgrade technology or if you are someone suffering from hearing loss and believe the cochlear implant may be the best solution for your hearing needs, contact our clinic at 904-399-0350.
The Benefits of Binaural Listening
The question regarding whether to purchase one or two hearing aids is an important topic to address with your audiologist during a hearing aid consultation. Hearing aids are an investment in your hearing health that can contribute to improved communication with family and friends and lead to better quality of life. Hearing aids are also a financial investment and it makes sense that many people want to weigh the benefits versus the cost.
In some cases one hearing aid truly is the best option. For example, a person may have a hearing loss in only one ear and normal hearing in the other ear. Another example is a person who has very little useful hearing in one ear; in this case a hearing aid may not provide any benefit at all and a cochlear implant may be the better option. In most other cases if both ears have a hearing loss then two hearing aids are better than one.
Binaural hearing is the term used to refer to hearing with two ears (whether with two normal hearing ears or with two hearing aids). Bimodal hearing applies to people who wear a hearing aid on one side and a cochlear implant on the other ear. Studies have shown that binaural/ bimodal hearing have many benefits and leads to improved communication ability.
Detecting Location of Sound
The ability to detect where sounds are coming from is called “localization” and is a function of the brain that is dependent upon sound being heard well by both ears. The brain uses timing and loudness cues to determine which ear received the sound first and at which ear the sound was louder in order to determine where the sound is located. The brain is unable to detect the location of sound accurately with only one (amplified) ear.
Understanding in Noise
When sound reaches the ears, the signal travels to the inner ear and is then transferred to the hearing never. It then travels up the brainstem to the hearing centers of the brain. The brain analyzes and combines the sound heard from both ears to help “tease out” the speech signal from the unwanted background noise. If the brain only receives sound from one amplified ear it has much more difficulty separating speech from noise.
When sounds are received by both ears the signal travels through multiple pathways in the brainstem. This double input of information to the brain creates a boost in the volume of the speech signal making it easier to hear. This boost or summation of volume does not occur with one ear.
Studies have shown that when the brain listens with two ears, less effort is needed to hear and understand speech which helps to reduce fatigue.
