Moving Beyond the Audiogram Towards a Patient-Centered, Interactive First Fit

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.

Listening Effort, Speech Intelligibility, and Narrow Directionality

Dr. Veronika Littmann at Signia R&D, 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.

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.

SPEECH

The SPEECH 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, SPEECH steers a conglomerate of algorithms and processes which work in concert to achieve the goal: less listening effort.

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.*

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.
