Cros hearing aids: cost, pros and cons
Single-sided deafness (SSD) can profoundly impact daily life, making it difficult to localize sounds and understand speech. For Australians facing this challenge, CROS (Contralateral Routing of Signals) hearing aids provide an effective solution by transmitting sound from the impaired ear to the better-hearing ear. This guide explores how CROS hearing aids work, their benefits, and the top brands available in Australia, helping you make an informed decision to enhance your hearing experience.
What is a CROS hearing aid?
CROS (Contralateral Routing of Signals) hearing aids are a specialized solution for individuals with unilateral hearing loss, meaning they have significant or complete hearing loss in one ear. These devices capture sound from the impaired ear and transmit it to the better-hearing ear, enhancing the overall auditory experience.
How do CROS hearing aids work?
CROS hearing aids consist of two parts: a transmitter placed in the ear with hearing loss and a receiver in the better-hearing ear. The transmitter picks up sounds from the environment and sends them wirelessly to the receiver, which then delivers these sounds to the functioning ear. This setup effectively mitigates the “head shadow” effect, where sounds on the impaired side are blocked by the head and cannot be heard clearly.

Choosing the best CROS hearing aid in Australia
When selecting a CROS hearing aid, consider the following factors:
- Brand and Model: Popular hearing aid brands like Phonak, Signia, Oticon, and Starkey offer reliable CROS and BiCROS solutions.
- Features: Look for features such as Bluetooth connectivity, rechargeability, and tinnitus management.
- Comfort and Fit: Ensure the device is comfortable for prolonged use.
- Reviews: Reading user reviews can provide insights into the performance and reliability of different models.

- Starkey CROS Hearing Aids: Valued for their robust performance and customizability.
Difference between CROS and BiCROS hearing aids
- CROS (Contralateral Routing of Signals) hearing aids are for individuals with normal hearing in one ear and no hearing in the other, transmitting sounds from the non-hearing ear to the good ear.
- BiCROS (Bilateral Contralateral Routing of Signals) hearing aids are for those with hearing loss in both ears, not only transmitting sounds from the poorer ear but also amplifying sounds in the better ear, offering a more balanced hearing experience.
CROS hearing aid vs. BAHA
CROS (Contralateral Routing of Signals) hearing aids and Bone Anchored Hearing Aids (BAHA) both address single-sided deafness but differ in approach and technology.
CROS hearing aids use a transmitter in the non-hearing ear to capture sound and wirelessly send it to a receiver in the better-hearing ear, enhancing the user's ability to hear from all directions without surgical intervention. In contrast, BAHA systems involve a surgically implanted device that transmits sound vibrations directly to the inner ear via the skull bone, bypassing the outer and middle ear. While CROS aids are non-invasive and suitable for those who prefer a simpler solution, BAHA can offer superior sound quality and is often recommended for individuals with conductive hearing loss or chronic ear infections. Choosing between the two depends on personal preference, medical condition, and lifestyle needs.

CROS Hearing Aid pros and cons
CROS (Contralateral Routing of Signals) hearing aids provide significant benefits but also have some limitations:
Pros
- Enhanced Sound Localization: They transmit sound from the impaired ear to the better-hearing ear, allowing users to perceive sounds from all directions.
- Reduces Head-Shadow Effect: Helps overcome difficulties in hearing from the non-hearing side by sending sound to the functional ear.
- Advanced Features: Often includes modern technologies like Bluetooth connectivity and tinnitus management for added convenience and relief.
Cons
- Noise Interference: Background noise from the non-hearing side may interfere with sound clarity, particularly in noisy environments.
- Adjustment Period: Users might face a learning curve as they adapt to the new auditory setup.
- Limited Amplification: CROS devices do not amplify sounds, which may be less effective for those with substantial hearing loss in the better-hearing ear.

CROS Hearing aid fitting
Fitting a CROS (Contralateral Routing of Signals) hearing aid involves several key steps to ensure it meets the user's needs:
- Initial Assessment: The process starts with a detailed hearing evaluation by an audiologist to determine the level of hearing loss and the individual's specific requirements.
- Device Selection and Programming: Based on the assessment, the audiologist chooses a suitable CROS device and customizes its settings to match the user's hearing profile.
- Placement and Adjustment: A transmitter is placed in the non-hearing ear, while a receiver is positioned in the better-hearing ear. The audiologist adjusts the device to optimize sound transmission and clarity.
- User Guidance: The user receives instructions on how to wear, operate, and maintain the hearing aids.
- Follow-Up Care: Subsequent appointments are scheduled to fine-tune the device and address any issues, ensuring the CROS hearing aid provides the best possible hearing experience.
CROS hearing aid and tinnitus
CROS hearing aids can be beneficial for individuals with single-sided deafness and tinnitus, a condition characterized by ringing or buzzing in the ears. Many CROS devices come equipped with tinnitus management features that help mask the distracting sounds. These features often include white noise or soothing sound options that can be adjusted to the user's preference. By improving overall hearing and providing specific tinnitus relief, CROS hearing aids can significantly enhance the quality of life for those struggling with both hearing loss and tinnitus. Audiologists can tailor these settings to suit individual needs, offering a comprehensive hearing solution.

What is the success rate of CROS hearing aids?
The success rate of CROS (Contralateral Routing of Signals) hearing aids varies based on several factors including user adaptation, fitting accuracy, and the hearing loss profile. Generally:
- User Satisfaction: Around 72.5% of patients have reported satisfaction with CROS and BiCROS hearing aids, indicating a relatively high success rate in terms of user acceptance and preference.
- Adoption and Effectiveness: Despite the benefits, adoption rates can be low due to various factors such as the complexity of the devices and user expectation.
- Clinical Success: Success rates in clinical settings often range from 80% to 90% when devices are properly fitted and users adapt well to them.
Overall, while CROS hearing aids are generally successful in improving hearing for those with single-sided deafness, individual experiences can vary.
