New technical investigations from Oticon demonstrate the vast difference of speed and clarity between the new Oticon More™ hearing aids and other premium hearing solutions that continue to use traditional directionality technology


Copenhagen, Denmark, 8th April, 2021 – Hearing aid manufacturer, Oticon, has released new evidence proving that the ground-breaking technologies in the Oticon More™ hearing aids outperform the traditional technologies still used in other premium hearing aids. Oticon More™ delivers clearer sound to the brain with high precision, all while letting users hear more of the sounds around them.

Mimicking real-world sounds, recorded with a spherical microphone to create a 3D image of the surroundings, Oticon has reproduced true-to-life sound environments in order to compare the performance of Oticon More™ to premium competitor hearing aids in a real-life environment. Using proven technical measures, Oticon tested; the achieved contrast between speech and the background in complex environments, the speed of adaptation of the device to suppress background noise, and access to speech details in the presence of noise. The results revealed:

  • Oticon More™ has increased contrast for a clearer full sound scene.

  • Oticon More™ adapts quicker to suppress background noise in the changeable sound environment.

  • Oticon More™ helps meaningful sound to stand out more which provides better speech understanding.

By clarifying the full sound scene, Oticon More™ ensures meaningful sounds stand out from the background

Looking at the signal-to-noise ratio in a real café scene, Oticon tested the clarity of speech the three devices provide with a speaker toward the front (-15 degrees) and a speaker to the side (-60 degrees). Oticon More™ and one other premium device performed well when focusing on a speaker to the front, with little difference in speech clarity, whilst the last premium device did less well. Oticon More™ was able to provide this level of clarity while also providing more of the relevant sounds in the environment. And it is clear just how important this level of sound detail is for a user when listening to a speaker that is not directly in front of them, as the study showed that Oticon More™ provides better clarity. Instead of depriving users of speech information that would help them fully participate in conversation, Oticon More™ supports users to understand more speech from more directions with much less effort.

Thanks to precision amplification, Oticon More™ ensures access to important sounds’ details

Using a spectrogram for a detailed time-frequency analysis, Oticon tested just how quickly all three test devices were able to access speech detail in the presence of noise. Oticon More™ not only proved to give users access to more precise details than the other premium hearing aids, with vowels and consonants clearly more prominent, but also proved to have much quicker reactions to changing sounds. Oticon More™ takes around 6 seconds to provide the clarity a user needs for understanding when the sound environment changes, while the other products on test take approximately 20 seconds or more to stabilize the sound picture.

In addition, Oticon looked at device adaptation over time to predict speech intelligibility**. With Oticon More™, users can enjoy higher speech intelligibility much faster as the hearing aid encounters a new complex sound scene.

“World sounds consistently change, and what our new research reveals is that traditional systems in hearing aids are too slow and singularly focused to support the user to hear well,” says Thomas Behrens, Chief Audiologist, Oticon. “Oticon More supports hearing loss in a radically new way. It features an advanced noise reduction feature which works in unison with a deep neural network to allow users to hear more of the relevant sounds ‘comfortably’. This not only provides a more natural hearing experience but based on these test results, Oticon More is a superior solution for taking part in even fast-paced conversation. . On top of this, we have documented that Oticon More reduces the listening effort for hearing aid users which can have many direct positive effects on their health and wellbeing.”

Oticon continues to take the lead in audiology with its ongoing development of industry leading hearing solutions. To read more about the technical investigations by Oticon detailed in this press release you can read the white paper here:
