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.

Listening Effort, Speech Intelligibility, and Narrow Directionality

Dr. Veronika Littmann R&D Audiology, together with Dr. Harvey Dillon and his research team at NAL recently published an article on Narrow Directionality in The Hearing Review. The article reports on a study which showed that Narrow Directionality provided a significant listening advantage in a laboratory experiment comprising a frontal target speech in diffuse speech babble. For this experiment, participants with moderate hearing loss matched the intelligibility performance of a group of age-matched near-normal hearers. The range of effort incurred in listening for the hearing-impaired participants also matched that of the age-matched, near-normal hearing group.

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.

Notch Therapy: A New Approach to Tinnitus Treatment

Tinnitus affects a staggering number of individuals. Population studies conducted in six different countries reported the incidence of prolonged tinnitus varying between 4.4 and 15.1 percent for adults. One study reported 2.4 percent of the population responded “yes” to the description of tinnitus as “tinnitus plagues me all day” (Moller, 2011).

Optimising hearing aid processing for music appreciation

Hearing aid manufacturers’ main focus has, up until recently, been improvement of speech intelligibility. Today’s hearing aid users have much broader demands however and often cite improved music perception as a key outcome or goal. Drs Tish Ramirez and Rebecca Herbig from Signia outline the changes in technology that hearing aid manufacturers are implementing to try to address this need.

Reducing Reverberation with EchoShield: Clinical Outcomes

Improved understanding of speech in background noise is a common desire of hearing aid wearers, and a design goal of hearing aid manufacturers. Over the years, technology has been developed to specifically address this concern. Noise reduction algorithms contribute significantly to sound quality and reduced listening effort; directional microphone technology can substantially improve the signal-to-noise ratio (SNR) at the ear of the listener.

Objective Measurement of Listening Effort

Listening Effort is the mental exertion listeners experience trying to solve an auditory task such as understanding speech (or detecting a target among interferers). Because listening effort is influenced by the clarity of the signal, it is therefore affected by hearing loss, as well as signal degradation caused by background noise or bad sound quality.

SpeechMaster

The SpeechMaster is the core of primax. This is the engine responsible for the automation of the Universal program, and it is clinically proven to reduce listening effort for the wearer throughout the day*. More than a single feature or innovation, SpeechMaster steers a conglomerate of algorithms and processes which work in concert to achieve the goal: less listening effort.

HD Music

As a major improvement upon the binax music program, an industry benchmark, primax offers three dedicated music programs. These dedicated music programs are uniquely designed to enrich the sound quality of music and to maximize the enjoyment of music, whether the wearer is listening to recorded music, attending a live concert, or making music himself.

EchoShield

Reverberation is the persistence of sound caused by sound waves reflected from surfaces. When the room is large or reflective enough, the reverberation mixes with the original speech source and degrades the signal quality. The EchoShield program reduces the effects of reverberation so that the sounds are clear and crisp again, reducing listening effort for the wearer.*

A New Wireless CROS and BiCROS Solution

While the majority of individuals with hearing impairment have hearing loss in both ears, 10% or so of this population have a unilateral condition. Of this group, for many, the impaired ear is unaidable, and this condition often is referred to as single-sided deafness.

Listening effort

Depending on the acoustic situation and the context, listening can require more or less attentional and cognitive processing. This dynamic activity of the brain which accompanies and enables listening is ongoing and cumulative. And it happens regardless of how much of the speech is actually understood.

Reducing Listening Effort via primax Hearing Technology

The primary goal of amplification is improving speech understanding. When listening situations become noisier or more challenging, this is even more important. However, beyond improving speech intelligibility, another indicator of the effectiveness of hearing aid fittings that has sometimes been overlooked is the cognitive demands, or listening effort required for speech understanding to take place. This is why it is important to not only improve speech understanding, but also make speech understanding easy. This is the underlying goal of the new Signia primax™ platform ― to improve speech intelligibility and reduce listening effort for the wearer.

Music Lovers and Hearing Aids

Some people cannot imagine life without music - it relaxes, inspires, and for many, completes their lives. Music has a different meaning for each person, and there are individual preferences, but most would agree that music listening should be enjoyable. This seemingly simple task easily can be undermined when hearing loss is present, as listening to just a limited part of the dynamics, or a reduced frequency range of our favorite music could significantly reduce the enjoyment of the experience.

Directionality Assessment of Adaptive Binaural Beamforming with Noise Suppression in Hearing Aids

In this work we present a new method for assessment of directionality in modern hearing aids, which has the benefit of simulating both a target source and an interfering source at the same time using speech signals. We show the benefits and the limitations of the method and present measurements for different microphone modes of different manufacturers. Furthermore, a sequential index based on these measurements is introduced.
