Signs of Hearing Loss, Hearing Aids and Hearing Implants - HearWorldUSA.com

Hearing loss affects one in ten Americans. It affects them in a variety of ways. Over time, it can lead to anxiety, depression, isolation, and decline in career performance. In children, it can result in what appears to be behavioral problems and lack of social and academic performance. By leaving hearing loss untreated, a physical condition may also become a psychological one. It is important to seek a diagnosis promptly. We've provided the quiz below for you and a checklist for parents of children suspected of having a loss.
Answering these questions is the right place to start:
Do people always comment that the volume on your TV or radio is too loud?
Have you missed visits and calls from people because you didn't hear the doorbell or telephone ringing?
Do you have trouble following conversations in crowded or noisy settings?
Do people seem to mumble and not speak clearly during conversation?
Do people tell you that you speak too loudly?
Do you frequently ask people to repeat themselves?
Do your friends and family suggest that you have a hearing problem?
Do you have a difficult time understanding the words of popular songs when listening to the radio?
Hearing Aids & Phonak Hearing Aids
There are many functions that set apart a Phonak hearing aid from others. SoundRecover is one of Phonak's most important and successful hearing aid solutions. Phonak has the right hearing aid - regardless of type of hearing loss, lifestyle, personal preferences, age or budget. Assistive Listening Devices develop outstanding hearing solutions for all individuals.
A hearing aids is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations.
A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.
The purpose of implantable hearing aids and cochlear implants is not to make a person hear normal again. Rather, they have revolutionized ways to stimulate and/or better amplify sound. Because each recipient has a different degree and type of hearing loss, all implants work differently for every person. Implant recipients are those who for a variety of reasons do not benefit from or cannot wear hearing aids.
A cochlear implant is a small, complex electronic device that can help to provide a sense of sound to a person who is profoundly deaf or severely hard of hearing. The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin (see figure). An implant has the following parts:
A microphone, which picks up sound from the environment.
A speech processor, which selects and arranges sounds picked up by the microphone
A transmitter and receiver/stimulator, which receive signals from the speech processor and convert them into electric impulses.
An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve
An implant does not restore normal hearing. Instead, it can give a deaf person a useful representation of sounds in the environment and help him or her to understand speech.
