What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test a Mobile Research App, known as Cochlear CoPilot, to evaluate its effectiveness in helping people with hearing loss understand speech. The trial examines how well this app works for adults with cochlear implants or hearing aids. Participants will use the app either in a clinic or both at home and in the clinic. Adults who use a hearing device and speak the test language fluently may be suitable for this trial. As an unphased trial, this study provides a unique opportunity to contribute to innovative research that could improve hearing aid and cochlear implant experiences.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial investigator.

What prior data suggests that this Mobile Research App is safe for measuring speech perception in cochlear implant recipients?

Research shows that the Mobile Research App, used to assess speech comprehension, is safe for humans. No evidence indicates safety problems with this app. It is designed to help people with cochlear implants or hearing aids improve their listening skills. Since the app is used for testing and practice, it poses much less risk than new drugs or medical procedures.

Similar apps, like the Cochlear™ CoPilot, have been used without any reports of problems, suggesting that the Mobile Research App is likely safe and well-tolerated. Participants use it to practice and improve their hearing both in the clinic and at home, offering flexibility and convenience. In summary, research supports the app's safety for users. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Speech Perception Assessment via Mobile App for hearing loss because it offers a new method for delivering therapy using technology. Unlike traditional treatments that require frequent in-person visits to assess and improve hearing, this mobile app allows cochlear implant and hearing aid users to practice speech perception at home. This convenience can lead to more consistent use and potentially better outcomes. Additionally, the app aims to gather data on how well users perceive speech over time, which could help tailor treatments more effectively in the future.

What evidence suggests that the Mobile Research App is effective for assessing speech perception in hearing loss?

Research has shown that mobile apps like Cochlear CoPilot can help people with cochlear implants improve their listening and communication skills. These apps provide information and interactive activities to enhance speech understanding. A study on a similar app found that it aided real-time speech processing and improved hearing techniques. Users reported better hearing through the app's skills training. In this trial, participants will use the Mobile Research App, either in-clinic or both in-clinic and at home, to evaluate its effectiveness in assisting cochlear implant and hearing aid users with speech perception. Although limited data exists on the Mobile Research App specifically, early findings suggest it could effectively aid in speech perception. ^{1 4 6 7 8}

Published Research Related to This Trial

This study introduces a new evaluation protocol for research platforms (RPs) used in cochlear implants (CIs) and hearing aids (HAs) to ensure their operational safety and reliability, which is crucial for advancing hearing restoration technologies.

The proposed two-phase analysis includes an acoustic phase to assess sound output safety and a parameter phase to evaluate the reliability of electrical stimulation, providing a structured approach to improve the design and testing of hearing devices.

A new smartphone application allows cochlear implant users to self-select frequency allocation tables (FATs) in real time, potentially enhancing their sound quality and speech perception.

In a pilot study with six cochlear implant subjects, all participants preferred a different FAT than the standard one, and their speech perception scores using the self-selected FAT were comparable to those with the clinical FAT, indicating the app's effectiveness.

In a study of 75 patients undergoing cochlear implantation, 39% experienced dizziness post-surgery, with most reporting delayed episodic vertigo that began a median of 74 days after the procedure.

Preoperative dizziness, older age at implantation, and earlier onset of hearing loss were significant risk factors for developing post-implantation dizziness, suggesting that these factors may influence vestibular symptoms after surgery.
