WSA says two clinical studies across 42 clinics in Spain, Canada and the United States found hearing aid conversion rates were 5 percentage points higher when clinicians systematically explored sound preferences. The studies report an association, not proof that the discussions alone caused the increase; further details about the study methods and comparison groups are limited in the published summary.
WSA says clinical studies at 42 hearing clinics in Spain, Canada and the United States found hearing aid conversion rates were 5 percentage points higher when professionals systematically explored patients’ sound preferences during consultations. The finding suggests that discussing how people want sound to be presented may be relevant to hearing aid selection, although the reported results show an association and do not establish that the approach alone caused more purchases.
The studies ran for more than three months and involved 63 hearing care professionals: 43 in Spain and 20 across the United States and Canada. Clinicians used WSA’s Sound Preference tool with new and experienced hearing aid users, followed by a discussion of the preferences expressed during the consultation.
The tool lets patients compare natural and enhanced sound designs across five listening scenarios. Clinicians can consider those preferences alongside hearing needs and other fitting requirements. WSA reported a 5-percentage-point global difference in conversion rates, with a 4.3-percentage-point advantage in the Spanish study and a 5.8-percentage-point advantage in North America.
In the Spanish study, about 40% of clients expressed a moderate or strong preference for one of the two sound designs. Their preferences were split approximately evenly between natural and enhanced sound, according to the report. Among Spanish clinicians surveyed, 84% agreed the approach improved the clinical experience they could offer, and 77% agreed it improved the likelihood of selecting the right hearing aid. Those figures reflect clinician views, rather than measured patient outcomes.
How Sound Preferences Could Shape Fittings
The results point to a practical issue in hearing care: people may value different listening experiences, and a fitting conversation can bring those preferences into the decision. Some listeners may favor a more natural balance between speech and surrounding sounds, while others may prioritize speech clarity in difficult environments. The reported preference split in Spain suggests that a single sound approach may not match every person’s expectations.
For patients, the approach may make selection more collaborative by giving them a structured way to describe what they hear and prefer. For clinicians, the tool offers another consideration when discussing options, without replacing professional judgment or individual hearing needs. The reported conversion difference could also matter to providers because it concerns whether people proceed with a hearing aid after consultation. However, the available summary does not provide enough detail to determine the size or reliability of that effect beyond the percentage-point differences reported by WSA.
WSA connects the findings to its use of two sound-design platforms. The company describes Widex Allure AI as aimed at listeners who prefer natural sound, with a Clarity Boost program for greater clarity in noise. It describes Signia Multi-adaptive Xperience as emphasizing speech clarity and comfort in complex environments. These are company descriptions of its products; the study summary does not establish that either platform is superior overall or that a particular design suits every patient.

From Sound Preference Program to Clinic Studies
The studies build on WSA Sound Preference, a program the company launched in April with research and clinical tools intended to help hearing care professionals discuss how sound preferences influence hearing aid experiences. The reported clinic work tested a tool-and-discussion approach during consultations with both new and experienced users.
The published account says the results reinforce earlier research on offering distinct listening experiences, but it does not provide the earlier studies’ methods or findings in detail. A separate white paper on the Spanish study is attributed to Laura Winther Balling, Ingrid Rubio Roldán and José Antonio Navarrete Salmerón. The report also identifies WSA as the hearing healthcare group behind the program and the study announcement.
Study Methods and Causation Details
The account does not specify how clinics or participants were selected, what comparison or control conditions were used, or how conversion was defined and measured. It also does not give participant totals, confidence intervals, or enough information to assess whether the differences were statistically significant. Those details limit how confidently readers can interpret the reported percentage-point differences or apply them to other clinics.
WSA’s summary describes the approach as associated with higher conversion rates. It does not establish that preference exploration caused the increase, nor does it show whether the effect persisted beyond the study period. The reported clinician survey results are perceptions and should not be treated as independent measures of patient satisfaction or fitting success.
Further Study Details and Clinical Use
The Spanish study’s white paper, by Balling, Rubio Roldán and Navarrete Salmerón, is identified as a source for additional information. WSA also directs readers to its Sound Preference website. The published summary does not announce a date for further study results or describe a planned follow-up trial.
For now, the reported findings offer clinicians a reason to explore patient preferences as one part of a fitting conversation, while weighing those preferences against hearing needs and professional judgment. More complete methods and independently reported follow-up data would help clarify whether the approach consistently affects purchasing decisions and patient outcomes.
Key Questions
What did the WSA studies report?
WSA reported that hearing aid conversion rates were 5 percentage points higher when clinicians systematically explored sound preferences during consultations. The reported difference was 4.3 percentage points in Spain and 5.8 percentage 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 source summary does not give specific start and end dates.
What does the Sound Preference tool do?
It lets patients compare natural and enhanced sound designs across five listening scenarios. Clinicians can discuss the patient’s responses and consider them alongside clinical needs.
Do the findings prove that preference discussions cause more purchases?
No. The report describes an association between using the approach and higher conversion rates. The published summary does not provide enough detail about comparison groups or study methods to establish that the discussions caused the difference.
What remains unknown about the results?
The summary does not detail participant totals, conversion definitions, statistical uncertainty or whether the effect continued after the study period. Those details would help readers judge how broadly the findings apply.
