CROS & BiCROS Hearing Aids: Enhancing Sound Perception for Unilateral Hearing Loss

Welcome to our comprehensive guide on CROS and BiCROS hearing aids, the ideal solution for people who have hearing in only one ear. This article will provide you with an in-depth understanding of CROS and BiCROS hearing aids, their benefits and limitations, how to get them, and how they can improve your daily life.

Understanding CROS and BiCROS Hearing Aids

CROS (contralateral routing of sound) hearing aids pick up sound from the side with no hearing and feed it into the hearing ear, while BiCROS (bi-contralateral routing of sound) aids amplify sound from both sides and feed it into the ear with better hearing. These types of hearing aids are designed to help people with hearing loss in one ear to hear sounds more clearly and be more aware of other noises around them.

CROS and BiCROS hearing aids are made up of a conventional hearing aid that sits in the hearing ear, and a microphone that looks like a hearing aid, which sits in the ear with no hearing. The microphone picks up sound from the side with no hearing and sends it to the hearing ear, providing a more natural hearing experience.

Types of CROS and BiCROS Hearing Aids

There are several types of CROS and BiCROS hearing aids available in the market, including:

  1. Behind-the-Ear (BTE) CROS and BiCROS: These hearing aids have a microphone and processor unit that sits behind the ear. The most prevalent CROS and BiCROS aids are BTE hearing aids, which are typically available through the NHS.

  2. Receiver-in-the-Ear (RITE) CROS and BiCROS: These hearing aids have a microphone and processor unit that sits behind the ear, with a thin wire connecting to a receiver (speaker) inside the ear canal. RITE CROS and BiCROS hearing aids are discreet and provide natural sound quality.

  3. In-the-Ear (ITE) CROS and BiCROS: These hearing aids are custom-made to fit inside the ear canal, with the microphone and processor unit sitting within the ear. ITE CROS and BiCROS hearing aids are more discreet than BTE versions and provide a comfortable fit.

  4. Completely-in-the-Canal (CIC) CROS and BiCROS: The only CROS and BiCROS hearing aids that are made to fit deep inside the ear canal are the Signia Silks. They are almost invisible. CIC CROS and BiCROS aids are the most discreet option and offer excellent sound quality.

  5. Invisible-in-the-Canal (IIC) CROS and BiCROS: These would fit even deeper within the ear canal, making them entirely invisible if they existed. Whilst IIC hearing aids do exist, their CROS and BiCROS counterparts do not.

Benefits of CROS and BiCROS Hearing Aids

CROS and BiCROS hearing aids offer several advantages for those with unilateral hearing loss, including:

  1. Improved speech understanding: With CROS and BiCROS hearing aids, users can better understand speech coming from their non-hearing side, making conversations more comfortable and enjoyable.

  2. Elimination of the "head shadow" effect: The “head shadow” effect occurs when the head obstructs sound waves, making it difficult to hear sounds coming from the non-hearing side. CROS and BiCROS hearing aids help eliminate this issue by routing sound from the non-hearing side to the hearing ear.

  3. Enhanced spatial awareness: CROS and BiCROS hearing aids improve spatial awareness by providing sound input from both sides, allowing users to better navigate their surroundings and detect potential hazards.

  4. Increased confidence in social situations: By improving speech understanding and spatial awareness, CROS and BiCROS hearing aids can boost users' confidence in social situations, making it easier to engage in conversations and enjoy group activities.

  5. Greater comfort in noisy environments: CROS and BiCROS hearing aids can help users distinguish speech from background noise, making it easier to communicate in noisy environments like restaurants or busy streets.

Limitations of CROS and BiCROS Hearing Aids

While CROS and BiCROS hearing aids offer numerous benefits, there are some limitations to consider:

  1. Difficulty localising sounds: Although CROS and BiCROS hearing aids can improve spatial awareness, users may still have difficulty determining the precise location of sounds due to the nature of the microphone's sound pickup.

  2. Limited battery life: As with all hearing aids, CROS and BiCROS hearing aids require regular battery replacement or recharging, which can be inconvenient for some users.

  3. Potential discomfort: Although modern hearing aids are designed for comfort, some users may find certain styles uncomfortable, especially if they are not accustomed to wearing hearing aids.

  4. Cost: Private CROS and BiCROS hearing aids can be expensive, especially for custom-made devices like ITE, and CIC models. However, BTE versions are usually provided by the NHS.
