Chariton Valley offers many devices that are Hearing Aid Compatible (HAC) for the hearing impaired.
M refers to the RF emissions level of the handset device, and means the device is intended for use with hearing aids in microphone mode. The higher the “M” rating number on the device, the more likely the device can be used with a hearing aid on the microphone setting.
T refers to the device’s telecoil coupling ability, and means the device is intended for use with hearing aids in telecoil mode. The higher the “T” rating number on the device, the more likely the device can be used with a hearing aid on the telecoil setting. A telecoil is a small device that is built into some hearing aids for use with the telephone as well as assistive listening devices. To use the telecoil, generally either the hearing aid is switched to the “T” position or a button on the hearing aid is pushed to select the telecoil program. Some newer hearing aids will automatically switch to telecoil mode when using a phone. The telecoil picks up magnetic fields generated by telephones and converts these fields into sound. Telecoils are particularly useful for telephone communication because they permit the volume control of a hearing aid to be turned up without creating feedback or ͞whistling,͟ and background noise can be reduced especially when using cell phones in noisy places. A hearing health professional can determine whether a hearing aid contains a telecoil and how it is activated.
