People with hearing loss can benefit from signaling and substitution systems, which convert sound or key strokes into another mode, 比如文字或闪烁的灯光.
信号和警报系统
Lights can be used to signal everything from the phone ringing to the 门铃. There are different ways of hooking a light into the 电话 line; 例如, when the phone rings, a light flashes. 它可以设置为在客厅里闪光, 即使手机在别的地方, 比如厨房. A light also can be hooked into a small transmitter in the 门铃, with a receiver triggering a light or a loud buzz in each room of the house, 哪一个可以通过家里的电线工作. Even when you are staying somewhere besides your house, 比如在酒店, 你可以要一个门环灯, which is placed on the inside of the door and lights when someone is knocking.
A 视觉烟雾报警器 如果你有听力损失,是必须的吗, as the sound signal generated by smoke alarms may not be sufficient to wake you up. Some alarms come with both visual and audible signals. They are as simple to install as the ordinary sound alarms. These also can be requested when staying in a hotel. 不幸的是, some of the 视觉烟雾报警器s in the hotels are not tied into the central 火灾报警 system. Some hotel chains are more sensitive to these problems than others, so the status of the 视觉烟雾报警器 should be verified whenever making reservations and when checking into a hotel.
也有 婴儿监视器 使用闪光灯. An intercom can be placed next to the crib of an infant or bed of a mobility-impaired person. A light-flashing receiver is then put in the parent or caregiver's room.
把所有这些系统整合起来——电话, 门铃, 火灾报警, baby monitor – there are base stations that convert each sensor into a different stimulus, 比如一个, 闪光两三次. In addition, the receivers can be worn on the wrist and deliver a vibratory or a light signal.
An all-weather microphone on the rear window or inside the trunk of your car can be installed to trigger warning lights from an indicator resting on the dashboard when an emergency vehicle is approaching with its siren on. The equipment and installation of this device can be reimbursed in many new automobiles. This program is called Emergency Alert Response Systems (EARS).
另一个汽车设备, 虽然不是免费的, is called a signal indicator and it lets the individual know whenever the turn indicator has been left on for longer than 15 seconds, 没有刹车. A dash light will flash and a buzzer gets louder and louder the longer the turn indicator stays on.

电话
The classic text display system is the teletype system (TTY). Several decades ago, a deaf physicist developed a way to connect TTYs through a 电话 modem. This opened up the world of telecommunication to deaf people. This is the same device that is sometimes called text 电话 (TT) or 电话 devices for the deaf (TDD).
A TTY system looks a bit like a typewriter with a built-in acoustic coupler for the 电话. A direct electrical connection to the 电话 line is used for permanent hookups. TTYs come in all shapes and sizes, the smallest ones are about the size of a notebook. If a phone call is received, a light will flash to signal you. 接电话的人将通过输入来接听电话, 例如, “你好, 这是马克, (“Ga”代表“go ahead”). The sender then types a message back to the receiver, which they can either read on a small screen or on a paper copy. To communicate this way, both the sender and the receiver must have a TTY.
If the person you want to speak to does not have a TTY, you can use a 电话 relay service. This is a national program, available in all states. 只需拨打711 在你的手机或TTY上. You can find more information on TTY relay services on the 全国聋人协会的网站 或者在 网上消费指南 由联邦通信委员会提供.
今天, many deaf people also use their computers and the Internet for real-time communication, and it's likely that this form of communication will increase exponentially in future years.
电视字幕
Televisions manufactured after 1994 usually include a chip that provides access to captioning. Click on the remote control menu or directly on the TV set, and cycle through the options until you see the closed captioning command. 它通常一开始是关闭的. 选择“在.“当你这样做的时候, the screen will show a written version of a program's dialogue and other information about sounds. Separate decoder units are available for TVs that do not have a closed captioned feature.
