Hearing aids collect sounds from the environment, amplify them and direct the amplified signal into the ears. Once hearing loss has been confirmed, 沟通需求评估是必要的,以确定是否或哪种助听器适合你.
助听器
You and your audiologist will examine, independently:
- Your communication needs.
- Preferred hearing aid style.
- Features of the devices.
助听器的样式不一定决定其电子元件或功能的复杂程度.
Hearing aid styles
- Behind-the-ear (BTE). 这种类型的仪器有两个部件——助听器和耳模. 助听器戴在耳后,并连接到一个定制的耳模,适合你的耳朵. 耳模是由外耳和耳道的印模制成的. 印模在听力学家的办公室拍摄,然后送到制造商生产.
- As the outer ear changes or grows, particularly in children, new earmolds should be made to maintain a proper fit. BTE助听器适用于所有类型和程度的听力损失以及所有年龄的人. 这是最适合婴幼儿和听力损失严重的人的风格.
- Open-fit mini BTE. 的 newest style available, 开放式迷你BTE结合了许多大款式的声学优势和小款式的美容优势. Open-fit instruments consist of a small BTE device, 耳廓,耳廓:钩住并紧紧跟随耳朵前部轮廓的窄管, 还有一个软的, non-occluding piece that directs sound into the ear canal. 对于低频听力良好的患者,开放的配合可以让自然声音进入耳道. 该仪器非常谨慎,吸引人的美容问题, and because it does not require custom molding, it often can be selected, programmed and fit in a single visit.
- In-the-ear (ITE). 这款助听器内置在一个定制的外壳里,外壳是用外耳的印痕制成的. 的 ITE is most appropriate for mild to moderate hearing losses. This style is not appropriate for infants or young children.
- In-the-canal (ITC). 这种助听器被安装在一个定制的外壳中,外壳是根据耳道的印模制成的. 这种风格最适合轻度到中度听力损失的人. While this is one of the smallest hearing aid styles available, 它可能不适合某些程度和配置的听力损失. It is not appropriate for infants or young children.
- Completely-in-the-canal (CIC). 比如ITC, 这种助听器被安装在一个定制的外壳里,外壳是根据耳道的印模制成的. 中耳道和中耳道的区别在于中耳道更靠近耳道,并且经常向鼓膜方向延伸. This aid is often the most hidden cosmetically, but is not invisible. 这种类型的助听器最适合轻度至中度听力损失的人, 并且可能不适合某些配置的听力损失. This style is not appropriate for infants or young children.
Digital hearing aids
Most hearing aids sold today contain digital circuitry. 数字助听器分析传入的声音并将其转换为数字信号. 然后可以根据个人的听力水平和听力需求来操纵信号, reconverted to an analog form (sound waves) and delivered to the ears, 不会产生通常与模拟技术相关的失真. 除了, these devices are often superior in terms of programming flexibility, 先进的电路压缩(放大柔和的声音,但不会过度放大响亮的声音), improved noise reduction, multiple programs, and the ability to minimize acoustic feedback.
Many digital hearing aids also have a directional microphone option, which helps with hearing in noisy environments. 数字助听器有不同的复杂程度, making them an affordable option for many people.
Communication needs assessment and hearing aid evaluation
In order to establish the appropriate plan of action, 您必须在过去六个月内由听力学家进行过完整的听力测试.
如果你最近没有做过听力测试,你可以到 UCSF Audiology Clinic. 一旦听力测试完成,你的沟通需求将被确定. 检查与您的保险,以确定您的保险范围之前,作出预约. If hearing tests are not covered by your insurance, there will be an additional fee for the evaluation.
成本
At UCSF Medical Center, 各种类型的助听器的自费费用从1美元到1美元不等,500 to $4,000 per hearing aid. 大多数双耳听力损失的患者使用双耳助听器.
保险 coverage and Medicare
医疗保险不包括听力测试、助听器评估或助听器的费用. Coverage for hearing aids from private insurance varies. 请直接与您的保险公司联系,以确定您的保单是否包括助听器作为承保福利,以及UCSF是否是您保单的助听器提供商.
的 UCSF Audiology Clinic can bill insurance companies for hearing aids, 但请注意,这通常需要事先获得保险公司的授权. If your insurance company does not pay the claim once it is submitted, you will be responsible for the full cost of the hearing aids.
