There are smartphone applications that can be used as a remote control for some hearing aids, tinnitus maskers, and portable microphones. With Bluetooth connections to your smartphone or tablet, you can stream music, videos, podcasts, and phone calls directly to your hearing devices. With the introduction of Bluetooth wireless connectivity, there have been many advancements in standard features of hearing aids, which act as a more complete and often seamless listening system. Additionally, there are similar ADs for fire and smoke alarm systems, carbon monoxide alarms, door bells, and baby monitors. For example, there are alarm clocks with strobe lights, or perhaps a vibrating pillow inserts-to help wake people who cannot hear the typical alarm. These ADs can use visual signals, such as a flashing or strobing light, vibrotactile indicators, for a vibration component, or alternative auditory signals, such as a louder alarm or one of a lower pitch. Alerting Devicesīeyond the most common ALDs mentioned above that help primarily with communication, there are also alerting devices (ADs) designed to help those with hearing loss stay safe and connected during day-to-day and emergency situations. To know if a venue is looped, look for the blue universal loop system sign. Induction looped systems are found in some theaters, museums, airports, places of worship, and even some taxi cabs. The signal can be from a microphone, PA system, or a telephone. In a “looped” area, such as a living room or auditorium, the T-coil picks up the electromagnetic signal and streams it directly into the hearing device. A telecoil is a small copper coil located inside the housing of many hearing devices and serves as a receiver or antenna. Telecoils, sometimes referred to as T-coils, and loop systems are another type of ALD and have been available in hearing aids for more than 50 years. Sound-field systems are not only beneficial for students with hearing loss, but many studies have shown that all students in the classroom benefit when sound field systems are used to improve classroom acoustics. With this system, the teacher wears a small, wireless microphone and the sound signal is sent to strategically placed speakers located across the classroom to enhance the speech signal to all pupils. Sound Field SystemsĪnother commonly used listening system designed for classrooms is a sound-field system. FM systems are also useful for adults in many listening situations such as noisy restaurants, meetings, lectures, and in places of worship. With the direct streaming to the listener’s ears, FM systems limit background noise, distance from the speaker, and effects of the acoustics of the environment, like reverberation/echoing. To connect with the FM system, it may require a neck loop or an ear-level receiver, sometimes referred to as a hearing aid boot. In a classroom setting, the teacher speaks into a small, portable microphone (usually clipped onto his/her collar or lapel) and the sound is delivered wirelessly to the student’s hearing device using FM signals. FM systems are micro-radio transmission systems that maximize the speaker’s voice. From infra-red TV headsets to closed-captions (CC) while watching TV or the phone to amplified telephones and stethoscopes, there are an array of ALDs to help people with hearing loss remain connected to their world.įrequency modulated (FM) systems are a type of ALD that makes it easier for those with hearing loss to hear in complex listening environments and are widely used in educational settings. Many people with hearing loss depend on or can benefit from some kind of ALD to help them develop or maintain a comfortable level of independence in their daily lives. Some of these situations include listening in the presence of background noise, at a distance, or in special circumstances such as listening to a television, while using a telephone, or at a lecture in a large hall. There are, however, some circumstances where additional listening support is useful and necessary. Hearing aids, bone-anchored implants, and cochlear implants are specifically designed to enhance conversational speech and work best in one-on-one situations and in relatively quiet environments. Assistive listening devices (ALDs) are devices used with or without hearing aids, bone-anchored implants, and cochlear implants to make sounds more accessible to people with varying degrees of hearing impairment.
