WSA says two clinical studies across 42 clinics found hearing aid conversion rates were 5 percentage points higher when clinicians systematically explored patients’ sound preferences. The results show an association; the supplied report does not establish that the approach alone caused the increase.
WSA reports that hearing aid conversion rates were 5 percentage points higher when hearing care professionals systematically discussed patients’ sound preferences during consultations, based on studies involving 42 clinics in Spain, Canada and the United States. The findings suggest that giving patients a structured role in comparing sound experiences may support decisions about hearing aids, although the reported results show an association rather than proving the discussions caused more purchases.
Across the studies, 63 hearing care professionals used WSA’s Sound Preference tool and a follow-up discussion for more than three months. The group included 43 clinicians in Spain and 20 in North America. They worked with both new and experienced hearing aid users during consultations. The report does not specify the number of patients involved or provide further details about how participants or clinics were selected.
The tool lets patients compare natural and enhanced sound designs across five listening scenarios. Clinicians can then consider those preferences alongside hearing needs and other fitting requirements. WSA reported a 4.3 percentage-point conversion-rate advantage in the Spanish study and a 5.8-point advantage in North America; the global average was 5 percentage points. These are percentage-point differences, not percentage increases.
In the Spanish study, about 40% of clients expressed a moderate or strong preference for one of the sound designs. Preferences were divided approximately evenly between natural and enhanced sound. Spanish clinicians also reported favorable views of the consultation process: 84% said it improved the clinical experience they could offer, and 77% said it improved the likelihood of selecting the right hearing aid. Those clinician responses are reported perceptions, not independent measures of patient outcomes.
How Preference Enters Hearing Aid Decisions
The results address a practical question in hearing care: whether discussing how sound feels to an individual can make the fitting conversation more useful and help patients decide whether to proceed. Hearing aid selection involves more than technical hearing needs; patients may also respond differently to the balance between speech and surrounding sounds. A tool that makes those preferences easier to describe could give clinicians another factor to weigh when discussing options.
For patients, the approach may make a consultation more collaborative by inviting them to compare listening experiences rather than relying only on a clinician’s description. For providers, the reported conversion-rate differences may be relevant to how consultations are structured. However, the report does not establish that preference exploration alone drove purchases, nor does it say whether higher conversion rates led to better long-term use, satisfaction or hearing outcomes. The findings are best read as early practice-based evidence supporting further evaluation, not a guarantee that the approach will work the same way in every clinic.

The Sound Preference Program
The studies build on WSA’s Sound Preference program, launched in April, which provides research and clinical tools intended to help hearing care professionals understand how individual preferences shape hearing aid experiences. The reported work applies the program’s tool in consultations and examines conversion rates alongside clinicians’ views of the process.
WSA says its product strategy includes two distinct sound-design approaches. Widex Allure AI is aimed at listeners who prefer a natural sound experience, while Signia Multi-adaptive Xperience emphasizes speech clarity and listening comfort in complex environments. The company says clinicians can use Sound Preference to inform a recommendation, while clinical judgment and other patient needs remain part of the decision. These product descriptions and intended audiences are WSA’s account; the study summary does not compare the products’ clinical effectiveness.
The report says the detailed Spanish study is described in a white paper by Laura Winther Balling, Ingrid Rubio Roldán and José Antonio Navarrete Salmerón. The supplied material provides fewer methodological details for the North American study and does not include a full description of the research design for both studies.
Limits of the Reported Results
The supplied report does not provide the patient sample size, baseline conversion rates, confidence intervals or other statistical details needed to judge the precision of the reported differences. It also does not explain whether clinics were randomly assigned, how conversion was defined, or whether factors beyond the preference discussions could account for some of the difference. Without those details, the findings cannot show that the tool itself caused conversion rates to rise.
It is also unclear whether the reported results apply to clinics or patient groups beyond those studied, and whether the approach changes longer-term hearing aid use or satisfaction. WSA’s figures are reported study findings, while clinicians’ ratings of the consultation experience are subjective responses. The available material does not provide an independent replication or a comparison of health outcomes between sound-design approaches.
Further Evidence and Clinic Use
The Spanish study’s white paper offers a route for readers to review more of the research, while WSA says the Sound Preference program and its tools are intended for hearing care professionals. The company has said the findings give it reason to continue advancing its sound-design platforms and preference program. The report does not announce a date for further studies or specify a next research milestone.
Further reporting would help clarify how the studies were conducted, how many patients took part and whether the conversion-rate association persists across a larger or more varied group of clinics. Longer-term data on patient satisfaction, hearing aid use and clinical outcomes would also help show whether preference discussions affect more than the initial decision to purchase.
Key Questions
What did the WSA studies find?
WSA reported that hearing aid conversion rates were 5 percentage points higher on average when clinicians systematically explored sound preferences. The reported advantages were 4.3 points in Spain and 5.8 points in North America.
Where and when were the studies conducted?
The studies involved 42 clinics in Spain, Canada and the United States and ran for more than three months. The report does not give exact start and end dates.
How does the Sound Preference tool work?
It lets patients compare natural and enhanced sound designs in five listening scenarios. Clinicians can use the discussion to consider preferences alongside hearing needs and other fitting requirements.
Do the findings prove that discussing preferences causes more purchases?
No. The reported results show an association with higher conversion rates, but the available account does not provide enough study-design and statistical detail to establish that preference discussions caused the difference.
What remains unknown about the results?
The report does not state the patient sample size, baseline conversion rates or detailed methods for both studies. It also does not report whether the approach affected long-term satisfaction, hearing aid use or clinical outcomes.
