Maintaining Narrow Directionality While Improving Soundscape Processing

Since its introduction with the binax platform in 2014, Signia’s Narrow Directionality has been the industry leader in optimizing speech understanding in background noise. The purpose of the current research was to ensure that the Narrow Directionality feature of the Xperience was equal to that of the Nx model—previous research has shown that the speech-in-noise processing of the Nx is superior to that of premier models from competitive manufacturers. Indeed, the results of this research revealed that there was no difference in the speech recognition findings for the two different instruments. This allows us to reasonably assume that Xperience also is superior to the competition for these important listening conditions. For those who were questioning if it is possible to obtain excellent soundscape processing for speech, while still maintaining a high level of narrow directionality, the answer is yes.

YourSound Technology and Dynamic Soundscape Processing

Signia Xperience devices take a significant step towards adapting to the listening intent of the wearer. YourSound technology is the realization of this comprehensive approach, consisting of the sensory analysis layer provided by Acoustic-Motion Sensors, the processing of environmental sounds in the Dynamic Soundscape Processing, and the Own Voice Processing to process the microphone input as soon as the system detects that the wearer is speaking. This article provides insights into the different components of YourSound technology.

Research Evidence for Dynamic Soundscape Processing Benefits

It is important that the design of hearing aid processing closely resembles the listening intent of the user. This has been enhanced with the Signia Xperience, which utilizes new acoustic and motion sensors, serving to improve speech understanding and the acoustic sound scape. Laboratory data shows significantly better speech understanding for speech from the sides, both when stationary and when moving. Real-world studies using EMA methodology revealed highly satisfactory environmental awareness, and higher overall user satisfaction ratings than have been obtained for either EuroTrak, or the recent MarkeTrak10. Overall, for both efficacy and effectiveness, the performance of the Signia Xperience hearing aids was validated, and increased patient benefit and satisfaction is expected to follow.

Industry Research: Clinical Comparison of Premier Hearing Aids

Premier hearing aid products from three leading manufacturers were placed in head-to-head competition to assess key benefits for the wearer. For the speech recognition measures, the Signia product was significantly superior, and this was true for three different background noise conditions. Subjective judgements for different attributes of the listening experience were equal for the three products, suggesting that superior speech understanding can be achieved without causing negative effects regarding the acoustic environment.

Closing the Open Fitting: An Effective Method to Optimize Speech Understanding

The findings of this research clearly show that the coupling system chosen by the HCP can have a substantial effect on subsequent speech understanding in background noise for the patient. The mean additional signal-to-noise ratio (SNR) benefit for a closed fitting was 3 dB, which corresponds to an impressive improvement in speech understanding of approximately 50%. This constitutes a significant advantage for the patient’s daily life in terms of social interaction. This benefit should not easily be foregone, especially in light of the clinically proven high acceptance of closed fittings based on the patient’s improved perception of his or her own voice as a result of Signia Own Voice Processing.

Better Speech Understanding with Signia Nx CROS/BiCROS Instruments

Patients with SSD often experience significant problems with speech understanding in daily listening situations where noise is a factor. The results of this study demonstrate that the two latest CROS/BiCROS solutions offered by Signia, the Pure 312 Nx CROS with Narrow Directionality and the Silk Nx CROS, provide clear and significant speech intelligibility benefits for users in challenging listening environments.

3D Classifier

At first glance, a tiny hearing aid and a self-driving car don’t have much in common. However, on a technological level there are a couple of similarities: self driving cars use a variety of sensors to collect real-time information about the environment such as GPS, optical cameras, specialised radar, and accelerometers.

The art of designing Pure Charge&Go Nx

Connectivity is undoubtedly one of the most im-portant topics in the hearing aid industry today. While most people immediately associate the word connectivity with being able to link their hearing aids with electronic devices such as smartphones, in a genuinely patient-centric hearing system the ap-plication of connectivity encompasses more than simply connecting to personal electronic devices.

Direct Streaming with Pure 13 BT

“Direct streaming” describes transmitting an audio signal from a mobile device to a wearer’s hearing aids - without using an intermediate accessory to relay the signal. Direct streaming is the most desirable streaming technology available for hearing aids, and has become even more important because of increasing usage of smart phones.

The Connected Ear

“Connectivity” is a word that is used a lot in today’s society, and for good reason. Whether we are connecting with friends and acquaintances on Facebook, using our smartphones to connect to media and news websites, or checking the weather, the theme of connectivity plays a big part in most people’s lives.

Motion Detection. A System for the Listener on the Move.

Pure 13 BT is the first solution that marries the until-now separate worlds of hearing instruments and advanced smartphone technology to improve signal-processing. With the new myControl app from Signia, the hearing aids can access information from the wearer’s smartphone, enabling them to detect the acoustic environment and anticipate the listener’s intent and preferences more precisely than ever before. The hearing aids cannot know for certain what the wearer wants to hear, but with the movement information, they can predict it with better accuracy. In addition, the user can control their instruments, monitor their acoustic environment and, of course, stream directly from their iPhone or iPad.

Signia Click Sleeves for RIC fittings improve audiological performance and usability

As digital hearing aids become increasingly advanced, the spotlight often shines on signal processing features, software functionality, and connectivity capabilities, rather than the physical components. At Signia, however, we constantly seek to improve every aspect of design, engineering, and production processes to create a better hearing aid. The new Click Sleeve for Receiver-in-Canal (RIC) fittings is a seemingly simple yet effective solution which improves both wearer comfort and audiological performance.

Multi-center Evidence of Reduced Listening Effort Using New Hearing Aid Technology

A review of clinical studies from three leading hearing aid research centers show a consistent trend for the Signia primax features to significantly reduce listening effort. Moreover, research from one site revealed that speech recognition performance for hearing-impaired listeners (pure-tone average 35-60 dB) using the primax Narrow Directionality algorithm was equal to that of normal-hearing individuals for the same speech-in-noise task.

Hearing Aid Batteries: The Past, Present, and Future

Modern digital hearing aids offer a huge variety of form factors, features, and wireless connectivity options that allow for individual hearing solutions. However, the price of functions like situation-based real-time processing, binaural algorithms, or streaming is an increased demand on battery performance. So far, the topic of efficient powering has received only scant attention, but this may change soon due to the many good reasons for using rechargeable batteries.
