Remote microphone hearing aid technology (RM-HAT) makes hearing and listening easier for a child with hearing loss.
RM-HAT systems include a transmitter and a receiver. The receiver is either attached to the bottom of the hearing aid or integrated inside of the hearing aid. The transmitter is worn close to the mouth of the person who is talking, usually a parent or teacher. The transmitter picks up the speech signal and sends it straight to the receiver. The child then hears speech as if the person talking is just a few inches away from them.
Children need access to speech to develop their hearing, language, and learning skills. To develop these skills, children need to be able to both hear sounds and words and tell them apart.
Young children who are learning language are unable to tell when speech is unclear or buried in background noise. Hearing speech clearly in noisy environments is much harder for children with hearing loss than for those with normal hearing. RM-HAT systems can help with this.
RM-HAT systems provide the following benefits for children:
Because the RM-HAT system sends the speech signal directly from the person speaking to your child’s hearing aid, it makes the voice of a person using the transmitter seem closer and louder. This makes speech louder and clearer for your child, which can improve your child’s:
The benefits of using an RM-HAT system are not always obvious right away, but giving children clear speech signals supports their long-term development.
RM-HAT can be used for children of all ages to help hear spoken language in noise or from a distance more clearly.
Using RM-HAT systems early is encouraged.
Children can use RM-HAT systems in a variety of listening situations, like:
RM-HAT systems can also be used with different media and technology, like cell phones, computers and laptops, gaming devices, music players, or school speaker systems. In those cases, the transmitter is connected to the media device so that the sound can stream directly to the receiver on or in your child’s hearing aids.
RM-HAT systems should be checked first thing every morning. To do this, place the RM-HAT transmitter near a sound source such as a radio or TV. Take the hearing aids connected to the RM-HAT receiver to another room. Turn on the sound source (radio or TV) and perform a listening check through the hearing aids. You should be able to hear the sound through your child’s hearing aids from a distance. Refer to the RM-HAT manufacturer’s manual for the specific instructions.
If there is no sound coming through the RM-HAT system, check the following:
If you are unable to get the RM-HAT system to work properly, contact your child’s audiologist for help or for repairs.
