White paper, M&RIE receiver preferred for sound quality and localisaton
Receiver-in-the-ear (RIE) hearing aids are the most popular style of hearing aid today. Unfortunately, the location of the microphones on the devices deprives users of natural cues for spatial hearing. ReSound ONE preserves these cues with the M&RIE receiver module. It places a microphone in the user’s ear canal along with the receiver and allows sound to be collected in the most natural location.
This article presents the results of two experiments that explored sound quality preferences and localization performance with the M&RIE and traditional RIE microphone location, as well as pinna compensation algorithms using the RIE onboard microphones.
Journal article, Research study, Remote fine tuning, Apps
A field trial at NAL with 30 experienced hearing aid users tested hearing aid outcomes and usability of the ReSound Smart 3D app and Assist remote services, as compared to in-person follow-ups.
Initial fitting procedure was the same for all patients, but only 15 patients tested the app and Assist. Of these, 12 patients requested fine tuning via the app, with 11 patients using it successfully (92%). Questionnaire and exit interview data from the 11 patients who successfully used the feature suggested that, while not perfect, the app was easy to use and that it was a good way to receive fine tuning services.
Outcomes measured on all patients at 6 weeks post- fitting via speech in noise testing, APHAB and SADL showed no difference between patients using the app/remote services and those who did in-person follow up visits.Leer meer
Journal article, Research study, Sound quality
In this field trial, 23 patients who had recently purchased ReSound LiNX2 RIEs at one audiology practice were refit with ReSound LiNX 3D RIEs.
They wore the new ReSound LiNX 3D devices for 4-6 weeks.
QuickSIN results were identical between hearing aids, but average satisfaction with sound quality measured via the SSQ12 and Hearing Aid Satisfaction Survey was significantly higher for LiNX 3D over LiNX 2 in various real-world listening situations.
70% of patients stated a preference for the sound quality of ReSound LiNX 3D and 65% opted to pay a 10% markup from the LiNX2 price to upgrade to LiNX 3D devices.Leer meer
White paper, Sound quality, Wireless streaming
This study conducted by an independent laboratory examined sound quality preferences specifically for sounds streamed from an iPhone for multiple premium hearing aids.
16 hearing aid users evaluated samples of streamed speech and music recorded from ReSound LiNX Quattro, LiNX 3D and five other premium hearing aids.
The recordings were customized to each tester’s hearing loss. ReSound LiNX Quattro was most preferred for both streamed speech and music, with ReSound LiNX 3D and one other hearing aid brand slightly but not significantly worse than ReSound LiNX Quattro.
Aspects of sound quality attributed to the ReSound devices included full dynamic range with clear details, a balanced bass/treble mix and lack of a hollow or restricted frequency response.Leer meer
Journal article, Directionality, Field study
This study examined performance and preference of asymmetric directionality settings in patients with differing SIN abilities. 28 men with symmetric SNHL – 16 of whom had symmetrical SIN abilities in each ear, while 12 had a left ear SIN advantage – completed the study.
Patients with asymmetric SIN abilities performed more poorly on SIN tests than the symmetric SIN group – and asymmetric directional settings affected their SIN scores differently than the symmetric SIN group.
However, the asymmetric SIN group’s real-world experience with asymmetric directionality was not significantly impacted by settings for omni/directional ears.
This suggests that patients with asymmetric SIN abilities can still benefit from the advantages that asymmetric directionality provides.Leer meer
Journal article, Teleaudiology, Apps, Field study
Fourteen tech-savvy hearing aid users compared in-person and remote fine-tuning appointments in this field study from the Hearing Center in Oldenburg, Germany.
Each participant experienced both a remote fine-tuning session using ReSound Smart 3D and ReSound Assist and a face-to-face fine tuning over a wear time of 3 weeks.
The order of each fine-tuning appointment was counterbalanced across participants. The fine-tuning method did not significantly impact average SIN scores, IOI-HA scores measured at each visit.
The participants rated ReSound Assist as highly usable, both after this short 3-week trial and after an additional 4 weeks of wear time for 10 participants who owned their own compatible smartphone.Leer meer
Journal article, Remote microphones, Apps
This study examined how different remote microphone technologies may affect speech recognition in a simulated classroom setting. 15 experienced hearing aid users with moderate to severe HL were fitted with ReSound LiNX2 hearing aids.
Speech recognition in quiet and in noise using the AzBio was measured using hearing aids alone, hearing aids + fixed-gain remote microphones with omnidirectional (ReSound Mini Mic) and adaptive directional mics (ReSound Multi Mic) and hearing aids + adaptive-gain, adaptive directional remote microphone system (Roger Touchscreen with Roger X receivers).
Results showed that all remote mics were superior to hearing aids alone in noise, and that the adaptive gain system (Roger) performed best in the worst SNRs, while both adaptive directional remote mics (Multi Mic, Roger) outperformed the omnidirectional Mini Mic in more moderate SNRs. These results can help clinicians find the best solution for patients while balancing performance, convenience and cost.Leer meer
Journal article, Real ear measurements, Open fittings
Variability in real ear measurements (REM) is a real issue that can affect the accuracy and practical application of hearing aid fitting verification. This study examined how different types of hearing aid fittings, including the popular open fitting, can affect the variability seen in REM.
Insertion gain measurements were conducted on 20 ears using 5 different conditions – BTEs with standard tubing and custom earmolds, BTEs with thin tubes and open and tulip domes, and RIEs with open and power domes – and 2 different audiologists who measured each condition twice.
None of the variation in REM between the 2 testers, the 5 hearing aid conditions and the 2 test-retest sessions were found to be significant. This shows that REM is reliable in open fittings, as long as care is taken to ensure appropriate REM procedures, especially proper probe tube insertion.Leer meer
Journal article, Directionality, Field study
While benefits of asymmetric directionality had been demonstrated in laboratory settings, this field study set out to determine how listeners in the real world may function with an asymmetric directional fitting.
12 experienced hearing aid wearers wore their own hearing aids (represented by various brands) in two counterbalanced at-home trials – 1 program with bilateral omnidirectional microphones and 1 program with asymmetric directional (1 ear omni, 1 ear directional). They logged their hearing aid use and ease of listening in each microphone mode.
The participants did indicate greater ease of listening for asymmetric mode, though this was only in situations where directional microphone use would be expected. They did not show a strong preference for either microphone mode, meaning that the participants were able to benefit from the asymmetric directional mode without impacting satisfaction for environments where omni is typically preferred.Leer meer
Journal article, Environmental classification, Datalog, Field study
This observational study examined the acoustic environments experienced by older adults using ReSound hearing aids, over both a 6-week and 13-month trial period.
The data collected by the hearing aids suggested that the older adults spent an average of 60% of their time in quiet or one-on-one speech situations, which matched closely with measures of social activity conducted before the start of the trial.
It provided evidence that sound environmental classification is accurately identifying the acoustic situations patients are encountering, due to the high correlation of datalogging obtained in left and right hearing aids for each listener. This, in turn, helps to ensure the automatic processing features of the hearing aid are activating in their intended environments.Leer meer
Journal article, Directionality, Speech recognition
Asymmetric directionality utilizes both omnidirectional and directional settings in diffuse noise environments to improve audibility of desired signals while also preserving environmental awareness. This study looked at how different speech and noise configurations can affect performance in an asymmetric directional program.
Two noise conditions were tested – speech in front with diffuse noise behind the listener and speech on the right side of the listener with diffuse noise on the left. Bilateral directional was best for speech in front, while directional mode towards the noise source was more beneficial than directional mode towards the speech when speech was on the side.
This study doesn’t replicate real-world scenarios, but rather shows the importance of adaptability of an asymmetric microphone mode. While did not always show the greatest benefit, the ability of the program to adapt to different microphone configurations can help encompass a wide variety of dynamic noise environments.Leer meer
Journal article, Sound quality
Sound quality is one of the most important drivers of patient satisfaction with hearing aids – but defining sound quality, and what makes good, is very subjective.
A new methodology to better assess sound quality attributes of hearing aid output was developed by an independent lab. Hearing-impaired listeners were trained to assess various aspects of sound quality, such as naturalness, bass/treble mix, reverberation, loudness and distortion.
They then assessed passages of speech and music recorded through six premium hearing aids. ReSound hearing aids were top-rated for sound quality over two generations of hearing aid products.
High ratings for sound quality were associated with high levels of naturalness and low levels of distortion.Leer meer
White paper, Mild hearing loss, Sensorineural hearing loss
Permanent perceptief gehoorverlies bij volwassenen is een van de meest voorkomende gezondheidsproblemen bij oudere volwassenen. Huisartsen spelen een belangrijke rol in de hoorgezondheid van oudere volwassenen. Veel patiënten bespreken gehoorproblemen voor het eerst met hun huisarts en deze patiënten gaven aan dat het advies van hun huisarts de belangrijkste factor was bij het bepalen of ze iets deden om hun gehoorproblemen aan te pakken, inclusief het proberen van hoortoestellen.
Journal article, Real ear verification, Wireless streaming, Smartphones
Gezondheidszorgtechnologie wordt steeds meer geïntegreerd met consumentenapparatuur, en hoorgezondheidstechnologie vormt hierop geen uitzondering. Nu steeds meer gebruikers van hoortoestellen profiteren van de smartphone-connectiviteit met hun hoortoestellen, is de vraag hoe ervoor gezorgd kan worden dat gestreamde audio geoptimaliseerd is voor het gehoorverlies van een gebruiker belangrijker dan ooit geworden.
Er is echter weinig klinisch advies over hoe dit kan worden bereikt. In dit artikel stellen we een nieuwe methode voor, specifiek voor het verifiëren van de output van hoortoestellen voor signalen die rechtstreeks van een smartphone worden gestreamd.
Survey data show that hearing care professionals seldom make adjustments to advanced feature settings, although personalization of these settings may not be optimum for an individual user.
This paper describes a new advanced feature prescription in SmartFit fitting software and reviews the scientific literature that informed the development of this prescription.

Journal article, Real ear verification
Real ear measurements (REM) are a crucial part of verifying hearing aid fittings. This article discusses how stimulus type and hearing aid settings can impact REM results.
Pilot data measurements with three hearing aids demonstrated that when a speech stimulus, such as the ISTS, was used for REM, the hearing aid features used in everyday listening programs could remain activated and have less than a 2 dB effect on REM output.
Pure tone or speech-shaped noise, on the other hand, caused differences in output depending on what features were activated and how long the stimulus was presented. This variability also depended on hearing aid brand.Leer meer

Journal article, Teleaudiology, Apps
Hearing care professionals can gain valuable insights into the amount of time they spend on appointments each day, but most clinics don’t have the ability to step back and examine this information. This article analyzed anonymized appointment data for over 80,000 patients in a large hearing aid clinic over a 9-year period.
Fine tuning appointments represented nearly 30% of all appointment types, with nearly all taking 30 minutes or less time to complete. However, most clinicians and patients know that much more than 30 minutes is spent in total when accounting for travel and wait times.
Insights like these, along with solutions for increasing efficiency and convivence, can help inform other clinicians regarding their own practices.Leer meer

Journal article, Fitting protocol, Real ear verification
Protocols for fitting and fine-tuning hearing aids have been developed by multiple experts in the field, but little has been discussed about a fitting “philosophy” – the more personal aspect of providing hearing care that is shaped by the hearing care professional’s experience and what each patient beings to the table.
This article delves into concepts relating to fitting philosophy and how hearing care professionals can develop their own patient-centered models for practice and how it can affect hearing aid fittings.Leer meer
Journal article, Fitting prescription, Fitting protocol, Real ear verification
The gain or output display in fitting software does not necessarily match closely with the actual output in a patient’s ear.
This is due in part to the COupler Response for Flat Insertion Gain (CORFIG), which must convert coupler gain to simulated real ear gain, as well as the issue of creating the “average” real ear in the fitting software.
Details on the effects of these and other variables on simulated real ear view are discussed.Leer meer

De Covid-19-pandemie heeft een impact gehad op de communicatie voor mensen met gehoorverlies. In de huidige studie onderzochten we de impact van de Covid-19 pandemie in februari 2021 op een groep van 294 slechthorende volwassenen die in de grootstedelijke gebieden van Kopenhagen, Denemarken (CPH) en Chicago, Illinois (CHI) woonden.
Deelnemers werd gevraagd om hun functioneren te beoordelen op vijf gebieden: gehoor en hoortoestellen, tinnitus, communicatie, gedrag en emoties. Deelnemers met een slechter gehoor rapporteerden de grootste moeilijkheden in de communicatie met anderen die maskers droegen en grotere emotionele gevolgen, ongeacht de leeftijd of de regio waar ze woonden.
White paper, The evolution of the ReSound binaural hearing strategy: All Access Directionality and Ultra Focus.
Adult hearing aid users wear their hearing aids in a wide range of acoustic environments, including a high proportion of time in less complex ones. Their preferences and listening goals are also variable. Therefore, it is important to provide the best possible hearing experience in all types of these real-life situations. ReSound ONE introduces the innovative All Access Directionality to help users hear well in all their daily life environments. All Access Directionality brings new, advanced directional technology to the evidence-based binaural approach to applying directionality that ReSound pioneered. In addition, Ultra Focus can be activated by users to hear better in one-to-one conversations in especially noisy conditions where they desire extra help.
White paper, An innovative RIE with microphone in the ear lets users “hear with their own ears”.
The Receiver-in-the-Ear style of hearing aids has overtaken the hearing aid market. The popularity of the RIE makes sense. It is robust, comfortable, discreet to wear, and can offer the most comprehensive collection of features. A significant drawback of the RIE is that the microphones are in an unnatural location to deliver sound to the individual ear. As yet another example of how the ReSound Organic Hearing sound philosophy inspires innovations that mimic and preserve natural hearing processes, the ReSound ONE RIE hearing aid can be fit with the M&RIE. This innovative receiver module places a microphone in the user’s ear canal so that sound can be naturally shaped by the individual’s unique anatomy, giving users all the benefits of the RIE style with the most natural sound quality.

Journal article, Directionality, Severe to profound hearing loss
Directional microphones have long been utilized in hearing aids to improve speech understanding in noise, but the implementation of directional microphone modes can be vastly different and likely have different effects on listeners. This study examined how ReSound’s Binaural Directionality III feature – which is designed to take advantage of both omni- and directional microphones in noise – impacted SIN understanding compared to 2 binaural beamforming features commercially available in hearing aids from other brands.
10 listeners with moderate hearing loss, and 7 with severe to profound loss, were fitted with the three hearing aid brands and completed an adaptive SIN task in three listening setups -speech from the front, from the side and from behind the listener. Binaural Directionality III significantly outperformed the other 2 brands when speech was either to the side or behind the listeners. One brand of binaural beamformer was better for speech in front than ReSound, but only for the moderately impaired listeners.Leer meer
Journal article, Wireless streaming, Phone use, Severe-to-found hearing loss
When direct-to-hearing aid MFi streaming became available, the opportunity for patients to benefit from added visual cues during phone calls via FaceTime also became a reality. This trial examined how various phone calls techniques used with hearing aids might affect speech recognition for hearing-impaired listeners.
15 listeners with severe-to-profound hearing loss attempted a speech in noise task with audio routed through an acoustic phone, through a wireless PhoneClip+ device and through direct MFi streaming with and without FaceTime. Unilateral versus bilateral streaming was also investigated. Streaming the phone call via any method over acoustic greatly improved understanding in noise, as did bilateral streaming over unilateral.
The visual cues provided by FaceTime were also of significant benefit, with a 23% average improvement over audio only, even when using unilateral streaming.Leer meer
