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.
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.
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.

When selecting a CROS hearing aid, consider the following factors:
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.

Fitting a CROS (Contralateral Routing of Signals) hearing aid involves several key steps to ensure it meets the user's needs:
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.
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:
Overall, while CROS hearing aids are generally successful in improving hearing for those with single-sided deafness, individual experiences can vary.
