TelecoilTelecoilThe hearing aid is able to pick up audio from landline telephones or public audio systems without using its acoustic microphones. This minimizes background noise and improves clarity and understanding, even over great distances. At performing arts venues, events, government meetings, etc., look for assistive listening systems (hearing loop, FM, and infrared systems), which must be provided at no cost under the Americans with Disabilities Act (ADA) and other international regulations.

Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.

Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.

DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.
