Signia AX, introduced in 2021, is a significant departure from traditional signal processing found in other hearing aids, and it addresses the most common problem associated with hearing aid use: performance in background noise

Auto EchoShield in Signia Augmented Xperience (AX) hearing aids addresses the situation where a hearing aid wearer is present in a room with reverberation caused by multiple sound reflections (echoes) from the room surfaces, for example in a church or entrance hall.

Since its introduction, Own Voice Processing (OVP) has been a unique technology only offered by Signia, preserving the familiar sound of the hearing aid wearers’ natural own voice.

Signia commissioned Ramboll a/s to conduct a life cycle assessment (LCA) study in accordance with ISO standards 14040 and 14044 for two comparable hearing aid devices and their respective battery solutions, i.e. a primary, non-rechargeable battery and a secondary, rechargeable battery. The overall aim was to investigate and understand the environmental impacts of two comparable hearing aid devices with different battery solutions. The two products chosen for assessments are rechargeable Signia Augmented Xperience (AX) and non-rechargeable Signia AX.

Recently, Signia introduced the AX platform of hearing aids to take the next step managing and augmenting the listening experience. The AX platform builds on former platforms, but also incorporates new approaches to processing. Part of the AX development was to look at how other industries approach sound and explore opportunities to expand on previous approaches.

To investigate the benefits of an AI assistant to support the individualization of hearing aid fittings, 58 hearing aid wearers were surveyed. The results showed Signia Assistant is perceived as easy to use and improves the fitting for individual wearers in difficult listening situations. Further, it increases the clinician’s ability to optimize the fitting more accurately to the individual and strengthens the provider-wearer relationship.

The combination of acoustic and motion sensors provides the hearing aids with data to better optimize the hearing aid features in anticipation of the hearing aid user's listening needs.

Seminars in Hearing, September 24, 2021

Signia has a long track record of developing innovative amplification features that optimize wearer performance in all types of challenging listening situations. The goal of optimizing wearer performance across a range of divergent listening conditions was the main driver in the development of the Signia Augmented Xperience (AX) platform with the revolutionary Augmented Focus™ technology.

Audiology Online, September 1, 2021

Understanding the principles of our unique and patented Augmented Focus technology is easy, when the methods the brain uses to focus on sound inputs are considered.

To test the wearers’ experience of Signia AX in real-world listening situations, an international survey was done in which respondents were fitted with Signia AX devices and then assessed the devices in their everyday life and compared the performance to that provided by their own hearing aids. In this white paper, we present preliminary data from the US part of the survey. The data indicate high levels of satisfaction with AX in a variety of listening situations and a clear preference for AX over the respondents’ own hearing aids.

Due to the restrictions dictated by the COVID-19 pandemic, a fully remote study of Signia AX was done in collaboration with Hörzentrum Oldenburg in Germany, involving both fitting and assessment of Signia AX being done in the participants’ own homes. The results showed high levels of immediate satisfaction with AX just after the fitting, and in an at-home speech-in-noise test, the new Augmented Focus processing allowed the participants to perform significantly better with AX than with their own hearing aids.

In a study at the University of Northern Colorado, the performance of Signia AX was tested in challenging communication situations simulated in the lab. The results showed that activation of the new Augmented Focus processing significantly improved the participants’ ability to understand speech in a restaurant scenario. Furthermore, the speech-understanding performance exceeded that offered by two main competitors and was on par with the performance of a normal-hearing reference group. In a simulated party scenario, the performance with AX was even better than normal-hearing performance when binaural beamforming was activated.

The white paper discuss important aspects of fitting hearing aids to people with severe to profound hearing loss in general, and specifically highlights the new features in Signia Motion C&G SP X supporting and innovating this field, also supported by study results.

A survey of 56 hearing aid users compared users’ satisfaction between Xperience and their own hearing aids, showing higher satisfaction ratings for Xperience across the board. The advantage for Xperience was especially pronounced for listening situations where the integrated acoustic-motion sensors, advanced directionality and noise reduction of the Xperience instruments help users lead their lives. These satisfaction ratings are compared to norms from MarkeTrak and EuroTrak, showing that even though hearing aid satisfaction is generally quite high, the Xperience instruments stand out.

The use of masks and increased distancing while talking because of the coronavirus pandemic is a unique challenge that can be very frustrating even for people with normal hearing. But for the hard of hearing it can prove especially difficult. Signia offers flexible solutions for you as a Hearing Care Professional (HCP) to optimize speech intelligibility in this “new normal” world. This new audiology bulletin explains the adverse effects of masks and social distancing on speech understanding and how HCPs can improve their clients’ hearing experience with the right advice and program settings in Connexx.

Times are changing and the need for new tools to provide support has never been higher. The Signia Assistant is founded on over 130 years of audiological experience and trust in the hearing care professional. Build on the Artificial Intelligence technology Neural Networks, it’s able to identify which adjustment suits the current environment best, based on both global and individual learning. For the user it means they can tailor their sound to meet their everyday situation, for the HCP it means a completely new insight tool into their wearer’s real world experience and use of the hearing aids. Relevant for the special situation we’re facing globally: The Assistant is also able to support with handling and troubleshooting and can act as the extended arm of the HCP. In this white paper, the Assistant is put to the test. Let’s see how it performs is real world user studies.

This paper describes in detail how to use the Signia Assistant, both in the Signia App and in Connexx for Hearing Care Professionals.

The StreamLine Mic from Signia is a versatile Bluetooth streaming device and remote microphone all in one.

And the remote microphone capabilities help make even though most difficult listening situations easier to manage. This white paper examines advantages and the performance of the StreamLine Mic

Options to offer services and solutions based on electronic processes and communication have in recent years been increasingly explored within the entire healthcare industry. Depending on the specific processes and technologies involved, such solutions are often referred to using umbrella terms like eHealth, mHealth, connected health, telemedicine or telehealth, but more field-specific terms have also been introduced.

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.

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.

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.

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.

One of the main concerns of Hearing Care Professionals (HCPs) who are fitting and dispensing hearing aids is knowing how to achieve excellence in patient service. A study involving 88 HCPs and more than 5600 first time users revealed the benefit of Signia TeleCare in creating higher hearing aid adoption rates with patients. The use of TeleCare was also found to result in high user satisfaction ratings in all the most relevant hearing situations for the individuals. The findings showed that a careful and consistent implementation as part of the HCP’s patient care workflow was key to leverage the remote care potentials provided by Signia TeleCare.

Today’s hearing aid fitting and counseling session should extend beyond the traditional hearing aid fitting & counseling protocol, in order to ensure user satisfaction in daily life right from the start. Exploring the benefits of Bluetooth technology and counseling regarding realistic expectations should therefore be routinely provided prior to leaving the Hearing Care Professional’s office. The paper gives detailed guidance how to conduct such an assessment for all manufacturer’s Bluetooth hearing aids, with further tips for Signia products utilizing manufacturer specific tools and features.

Few manufacturers offer technology that incorporates both bilateral full-audio sharing of signals as well as direct streaming from a mobile device. In a comparative research project, the effectiveness of the streaming for such hearing aids was evaluated. The findings reveal a crucial difference between streaming indoors and outdoors, which is important to consider when counseling patients. Results show a substantial streaming advantage for the Signia product, and indicate that a Bluetooth based wireless approach as applied by the competitor brand does not deliver on all basic user needs.

In an AmpCROS or TriCROS set-up, the aid on the poorer hearing side picks up the sound, amplifies it, and delivers it to both ears. The aid on the better hearing ear receives an amplified signal from the contralateral side and combines it with the ipsilateral signal. This short guide shows you how to use Signia NxTM instruments for an AmpCROS fitting.

Our goal at Signia has always been to allow our patients to live their lives to the fullest despite hearing loss. Therefore, we develop hearing solutions designed to ease and facilitate communication in a variety of listening situations. This paper describes several of our advanced features on the Nx platform and corresponding studies that demonstrate clinically proven benefit to patients.

This Hearing Review article presents a study which demonstrates that the two new CROS/BiCROS systems from Signia—Pure 312 Nx CROS with Narrow directionality and Silk Nx CROS—provide a superior solution to the daily listening problems encountered by people with single-sided deafness (SSD).

It’s debatable whether a computer will ever “think” in the same way that the human brain does, but machines’ abilities to see, understand, and interact are changing our lives. It is no surprise then, that in the past few years we have seen mention of machine learning in hearing aid trade journal articles. But are machine learning hearing aids really something new?

In a real-world field study, the Hearing Profile was shown to be a valuable tool for hearing care professionals, not only by providing an individualized first fit with an appropriate target prescription, but also a means to leverage the cooperation between professionals and patients which results in improved fitting success.

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.

An increasing number of wearers are relying on Bluetooth to stream phone calls to their hearing aids. Some options on the market which feature streaming to both ears contend that the bilateral signal fosters better speech intelligibility, but is this supported by research evidence, or just conjecture?

We have been taught that the occlusion effect often is the culprit in own voice issues, so why is it that with the prevalence of open fittings, patient dissatisfaction with the sound of their own voice is still an obstacle to hearing aid acceptance?

This Hearing Review publication reports on a study which uses three tests to evaluate the various aspects of hearing aid performance directly affected by the FBC: Aided Gain Before Feedback, Max-REIG, and a sound quality evaluation using Multi-Stimulus Test with Hidden Reference and Anchor (MUSHRA). Considering all potential trade-offs, the Signia FBC can be considered a best-in-class algorithm in this multifaceted benchmark analysis.

While hearing aid users often wear their hearing aids for music listening, they are frequently dissatisfied with the sound quality of music. This AudiologyOnline article details a study which describes music sound quality ratings between the universal and music programs of five premier market hearing aids, and which hearing aid achieves the best overall sound quality ratings.

AudiologyOnline, August 2017

It has long been known that pure tone audiogram (PTA) measurements cannot fully account for the variation in speech intelligibility scores measured from hearing impaired listeners. With regard to hearing aid fittings, it is clear that there is no simple solution that would allow us to perform a consistently perfect customized fitting by even adding one additional variable to audiogram data. A transition from the “average” patient fitting towards a more individual fitting requires several stages. In this paper, these stages are described and explained, based on data obtained from several clinical studies.
