Hearing Aid Compatible Some hearing aids have a feature called a "telecoil" built into them. The telecoil allows the hearing aid to hear magnetic signal representing an audio signal instead (or in addition to) just an audio signal. A device that is "Hearing Aid Compatible" is designed to output the required magnetic signal that the telecoil can hear in additon to an audio signal. The term "Hearing Aid Compatible" is usually used to refer to telephones, but may also apply to headphones. Also, hearing aid users who have a telecoil in their hearing aid may use an ALD with a neckloop or with a silhouette to allow them to hear devices that are not by nature "Hearing Aid Compatible". Headphones: Not all headphones are "Hearing Aid Compatible", but those that use powerful magnets to drive the speakers may be. The most common headphone that people may encounter that is "Hearing Aid Compatible" is the "PhonicEar" Headphone (really an ALD which many movie theaters have to loan free to patrons who would like to hear the movie better. Many users can simply use that ALD acoustically, but users with a telecoil in their hearing aids may benefit from switching it on, since that particular headset is "Hearing Aid Compatible". Telephones: Most non-portable telephones, some remote phones, and a few cell phones sold in the United States are now "Hearing Aid Compatible". This means that the telephone speaker in the earpiece not only outputs the sound of the person you are talking to, but it also outputs a magnetic signal representing the sound. All early telephones were automatically hearing aid compatible, because they used magnets to drive the speaker in the earpiece. Telephones built a few years ago were probably not hearing aid compatible, because they frequently didn't use magnets to drive their speakers. Using a equipped hearing aid with a Hearing Aid Compatible telephone can dramatically improve your ability to hear on the telephone. Shop carefully, however, since the strength and effectiveness of Hearing Aid Compatible phones and of telecoil varies greatly. If you have more than a minor hearing loss, you may want to check out the several Hearing Aid Compatible telephones and especially those Amplified Telephones designed especially for hard of hearing people.
Additional features Some hearing aid optional features improve your ability to hear in specific situations: Noise reduction. All hearing aids have some amount of noise reduction available. The amount of noise reduction varies. Directional microphones. These are aligned on the hearing aid to provide for improved pick up of sounds coming from in front of you with some reduction of sounds coming from behind or beside you. Some hearing aids are capable of focusing in one direction. Directional microphones can improve your ability to hear when you're in an environment with a lot of background noise. Rechargeable batteries. Some hearing aids have rechargeable batteries. This can make maintenance easier for you by eliminating the need to regularly change the battery. Telecoils. Telecoils make it easier to hear when talking on a telecoil-compatible telephone. The telecoil eliminates the sounds from your environment and only picks up the sounds from the telephone. Telecoils also pick up signals from public induction loop systems that can be found in some churches or theaters, allowing you to hear the speaker, play or movie better. Wireless connectivity. Increasingly, hearing aids can wirelessly interface with certain Bluetooth-compatible devices, such as cellphones, music players and televisions. You may need to use an intermediary device to pick up the phone or other signal and send it to the hearing aid. Remote controls. Some hearing aids come with a remote control, so you can adjust features without touching the hearing aid. Direct audio input. This feature allows you to plug in to audio from a television, a computer or a music device with a cord. Variable programming. Some hearing aids can store several preprogrammed settings for various listening needs and environments. Environmental noise control. Some hearing aids offer noise cancellation, which helps block out background noise. Some also offer wind noise reduction. Synchronization. For an individual with two hearing aids, the aids can be programmed to function together so that adjustments made to a hearing aid on one ear (volume control or program changes) will also be made on the other aid, allowing for simpler control.
How hearing aids work Hearing aids use the same basic parts to carry sounds from the environment into your ear and make them louder. Most hearing aids are digital, and all are powered with a hearing aid battery. Small microphones collect sounds from the environment. A computer chip with an amplifier converts the incoming sound into digital code. It analyzes and adjusts the sound based on your hearing loss, listening needs and the level of the sounds around you. The amplified signals are then converted back into sound waves and delivered to your ears through speakers.
BTE Cross System Cross systems are used for people with hearing loss in one ear or significantly more in one ear, this system allows the user to wear technically a microphone in one ear and the speech is transferred into a speaker in the good ear, whilst the cone in the good ear allow normal hearing
What are hearing aids? In its most basic form, a hearing aid is a device that amplifies the frequencies that you have trouble hearing. Most devices nowadays are digital, consisting of a microphone, digital signal processors, amplifiers, and speakers. Hearing technology has undergone a radical rate of evolution in recent years. The introduction of digital signal processing technology has allowed chips to process multiple millions of calculations per second, resulting in unparalleled sound quality. The durability has improved dramatically, and comfort, as well as aesthetics, have been thoroughly addressed. Modern devices have shrunk so much in size that they are barely noticeable.
