What is amplification for APD?

Generally, hearing aids amplify all the frequencies that a person has lost hearing in. In general, people with APD do not have hearing loss but still struggle to hear speech in noise. So, their amplification needs are different.

People with APD benefit from technologies that help bring speech above the background noise, as this will improve their speech understanding.

There are 3 ways that this can be achieved:

1. Sound field amplification
2. Remote Microphone system (sometimes called an FM system)
3. Low-gain hearing aids.

Both the Sound field and FM systems have a microphone picking up the person’s speech (usually a teacher/presenter).

The sound field amplification system would involve a series of speakers around the room allowing for improved speech understanding for all listeners.

The Remote Microphone system has a personal receiver that picks up the transmission and delivers it either via headphones or bilateral ear-level devices directly to the listener, affecting and only benefiting the listener.

The low-gain hearing aids would pick up the speaker’s voice and transmit it directly to the wearer’s ears. There are options to include a remote microphone with a hearing aid. The benefit of a hearing aid is that it would enhance all listening situations, rather than just single-speaker listening situations (like a classroom or church service).
