Improvements For Hearing Aid Users
With Coherence Technology

From research on hearing aid users and the data from discrete signal analysis techniques, CT offers  improvements in the following areas:

1. Greater speech intelligibility - more exchange with the auditory environment
2. Higher resolution of sound - users are reporting less need for increasing volume
3. Better speech separation - users are hearing better in crowds and in noise filled auditory environments
4. Improved hearing after prolonged use
5. Improved harmonic separation by the inner ear - change in the cumulative spectra of harmonics
6. Adjusted harmonic intensities to the needs of the user - different energy-time curve
7. Less cross talk between specific auditory signals - less cross correlation
8. More auditory information is reaching the ear - greater auto correlation.

Applications

Improving hearing aid performance using Coherence Technology (CT) offers significant benefits for users, scientists, technologists, innovators, and new product developers, alike. Here’s a closer look at each group's potential gains:
### 1. **Scientists**
For scientists, particularly those in the fields of audiology and acoustic engineering, CT provides a more precise and reliable framework for understanding auditory perception. By improving signal coherence, researchers can more accurately measure how the brain processes complex sounds, leading to advances in both the theory and application of auditory science.
### 2. **Technologists**
Technologists involved in the design and manufacture of hearing aids can use CT to enhance product specifications. The ability to reduce noise and increase sound resolution directly affects the usability and efficacy of hearing aids. These improvements can lead to broader acceptance of hearing aid technologies, especially among users who have previously been hesitant due to inefficacy in noisy environments.
### 3. **Innovators**
Innovators can leverage the improved metrics of sound quality offered by CT to develop new applications beyond traditional hearing aids. For example, applications in virtual reality environments, where clear and precise auditory signals are essential, or in environments with a high degree of auditory pollution, where clarity and noise cancellation can substantially improve user experience.
### 4. **New Product Developers**
For new product developers, CT provides a competitive edge in the rapidly evolving market of personal audio devices. The enhanced capabilities such as better speech intelligibility, speech separation, and improved harmonic separation allow for the development of highly differentiated products that cater specifically to niches like musicians, public speakers, or people regularly exposed to noisy environments.
### Value of Improved Hearing Aid Performance
By enhancing hearing aid performance using Coherence Technology, developers can provide users with:
- **Greater Speech Intelligibility**: Makes everyday communications easier and more effective.
- **Higher Resolution of Sound**: Reduces the need to increase volume, preserving hearing health.
- **Better Speech Separation**: Enhances the user's ability to distinguish speech in noisy settings.
- **Improved Hearing After Prolonged Use**: Potentially slows down hearing degradation by providing clearer sounds at safer volumes.
- **Improved Harmonic Separation and Adjusted Harmonic Intensities**: Tailors the hearing aid's response to individual user's needs, improving overall satisfaction and comfort.
This not only improves the quality of life for hearing aid users but also expands the potential market for these devices as they become more effective and appealing to a broader audience. Overall, Coherence Technology represents a significant stride forward in the intersection of audiology and signal processing, holding profound implications for multiple industries concerned with audio and sound technologies.
