This is where directional microphones make a big difference. That’s why simply amplifying sounds won’t fix the problem-speech and non-speech need to be separated from one another. This can make it difficult to fully understand conversations and engage in certain situations, such as in a crowd or at a restaurant. As with BTEs, these devices are for people with severe hearing loss or those with mild or moderate loss but with a preference for this design.Have you ever tried to have a conversation during a loud concert or at a movie and struggled to hear? This experience is an example of how excessive background noise can make it hard to hear speech-often what we want to hear most.įor those with hearing loss, differentiating speech from background noise and other distracting sounds is more of a challenge than it is for others. They are smaller than BTEs and can suffer from earwax clogging in the same manner as other devices designed for use deep inside the ear. In a RITCs hearing aid, a speaker is inserted within the ear canal and connected via a tube to an amplifier behind the ear. Receiver in the canal (RITC) or Receiver in the ear (RITE).Still, their raw amplification power makes them a good choice for people who have severe hearing loss. They are larger than almost any other device, but the powerful amplification they offer is seen by many as truly offsetting the large size and susceptibility to wind noise. These are for people with any level of hearing loss. Their speakers may become clogged with earwax, but the larger size is often seen as an advantage when it comes to additional features like easily accessible volume controls.īTEs hook over the ear and have a tube that connects to the ear canal itself. Designed for people with substantial hearing loss, these slightly larger devices have batteries with a longer life than more discreet alternatives. The former covers the entire ear bowl while the latter only covers the bottom half. ITE hearing aids are also customised to their wearers, and there are two versions: the full shell and the half shell. They can become clogged with earwax, but offer more features than CICs, such as easily accessible volume controls. Although they are not as small as CICs, they are compact enough to have tiny batteries that need to be changed more frequently than larger devices. ITC hearing aids must be customised to the wearer's ear for a proper fit but are useful for people with varying levels of hearing loss. ITC devices sit just within the ear canal and are visible to other people. These aids can also get clogged with earwax. CICs don't have much problem with wind noise, but their compact size has drawbacks: they use the smallest hearing aid batteries which need to be frequently replaced. They are well-suited to people with mild to moderate hearing loss. Kinds - What types of hearing aids are there?ĬIC devices are prized for being the smallest and least-visible type of hearing aid. All hearing aids work on the same general principles: A microphone converts sound to an electrical signal, an amplifier increases the signal’s strength, and the signal is converted back to audible sound for playback from a speaker near or within the ear canal.
