Widex PureSound™: A Revolutionary Breakthrough in Natural Sound for Mild-to-Moderate Hearing Loss

Why Widex PureSound™

Living with hearing loss can be a challenging experience, especially for individuals with mild-to-moderate hearing loss. The majority of individuals falling within this range are typically fitted with open or vented fittings, which aim to provide comfort and alleviate the feeling of occlusion. However, these fittings often come with a trade-off – artificial sound quality.

To address this issue, Widex, a renowned hearing aid manufacturer, has developed an innovative solution known as Widex PureSound™.

In this blog post, we will delve into the groundbreaking features of Widex PureSound™, its ability to overcome the comb-filter effect, and how it brings forth a new level of naturalness and transparent sound for those with mild-to-moderate hearing loss.

The Challenge of Open and Vented Hearing Aid Fittings

Open and vented fittings have been commonly used for individuals with mild-to-moderate hearing loss due to their ability to minimize occlusion effects. These fittings allow natural sound to enter the ear canal, providing a more comfortable listening experience. However, they often suffer from a significant drawback known as the comb-filter effect.

The comb-filter effect arises when sound waves from the hearing aid and those entering the ear canal mix together, leading to interference patterns that affect the perception of sound quality. This effect can result in a distorted, artificial sound that compromises the wearer’s ability to fully enjoy and comprehend their surroundings. Overcoming the comb-filter effect has long been a challenge in the audiology field, and this is where Widex PureSound steps in as a game-changer.

Widex PureSound™: A Breakthrough in Natural Sound Design

PureSound is an innovative alternative to the classic sound design in Widex’s Universal listening program, specifically developed for individuals with mild-to-moderate hearing loss. It employs advanced signal processing techniques to tackle the comb-filter effect, thus offering a more natural and transparent sound experience.

The technology behind Widex hearing aids using PureSound involves an intelligent algorithm that works in real-time to analyze and compensate for the interference caused by the comb-filter effect. By carefully manipulating the sound signals, PureSound can reconstruct the auditory input in a way that reduces the artificial sound and provides a more authentic listening experience.

Transparent Naturalness: The Perfect Impression

One of the most remarkable qualities of this innovative technology is its ability to deliver a transparent naturalness that leaves a perfect impression on the wearer. Unlike traditional open and vented fittings that often sound tinny or distorted, PureSound creates a more authentic sound perception, closer to how sound is naturally experienced.

This naturalness is achieved by preserving the integrity of the original sound source. By minimizing the comb-filter effect, Widex ensures that the hearing aid wearer can perceive sounds with improved clarity, richness, and depth. Whether it’s the delicate rustling of leaves, the melodic notes of a song, or the crispness of speech, PureSound allows individuals with mild-to-moderate hearing loss to rediscover the beauty and nuance of sound.

Beyond Sound Quality: Enhanced Listening Experience

This technology not only revolutionizes sound quality but also enhances the overall listening experience for individuals with mild-to-moderate hearing loss. By providing a more natural auditory input, PureSound promotes better speech understanding and sound localization, enabling wearers to effortlessly engage in conversations, enjoy music, and participate in various social activities.

Moreover, this improved sound quality translates into a reduced listening effort. With clearer and more distinct sounds, wearers can focus on the content rather than struggling to decipher muffled or distorted speech. This can lead to increased confidence, better cognitive functioning, and overall improved quality of life.

Customization and Adaptability

Widex PureSound also offers customization and adaptability to cater to individual preferences and specific hearing needs. Hearing care professionals can fine-tune settings to optimize the sound experience based on the wearer’s unique hearing profile and listening environments. This level of personalization ensures that the wearer receives the best possible sound quality and comfort, regardless of their specific hearing challenges.


Widex PureSound represents a remarkable breakthrough in the world of hearing aid technology, particularly for individuals with mild-to-moderate hearing loss using open or vented fittings. By successfully overcoming the comb-filter effect, PureSound offers a revolutionary alternative that delivers transparent naturalness and authentic sound perception. With improved speech understanding, sound localization, and reduced listening effort, wearers can truly immerse themselves in the rich tapestry of everyday sounds.

Thanks to these advancements, those with mild-to-moderate hearing loss can now experience the world in all its natural glory, enjoying a renewed sense of connection and quality of life.
