Assistive listening devices and systems (ALDS) help hearing impaired listeners overcome noise, reverberation, and distance. ALDS deliver speech from the lips of the talkers to the ears of the listeners. Thus, hearing impaired persons can function in the mainstream of society. ALDS include hardwire, infrared, FM, loops, and signaling and alerting devices. They help hearing impaired persons develop and maintain listening and talking skills. As a result, they can function at optimal levels of personal, social, educational, vocational, spiritual, and recreational activities. The use of "self-wiring," windscreens, and remote microphone technology make it possible for hearing impaired persons to enjoy communication in one-to-one situations; small and large groups; large listening areas; and settings such as television listening, communicating in an automobile, and counseling with medical, educational, vocational, and spiritual advisers. ALDS, combined with hearing aids, offer state-of-the-art listening and talking opportunities.
助听设备和系统（ALDS）帮助听力受损的听众克服噪音、混响和距离问题。ALDS将说话者嘴边的语音传送到听众耳中。因此，听力受损者能够在社会主流中正常生活。ALDS包括硬线、红外线、调频、感应圈以及信号和警报装置。它们帮助听力受损者培养和保持听力及交谈技能。结果，他们能够在个人、社交、教育、职业、精神和娱乐活动的最佳水平上发挥作用。使用“自布线”、防风罩和远程麦克风技术，使听力受损者能够在一对一的场合、大小群体、大型聆听区域以及诸如电视收听、汽车内交流以及与医疗、教育、职业和精神顾问咨询等场景中享受交流。ALDS与助听器相结合，提供了最先进的听力和交谈机会。
