WSA reports that hearing aid conversion rates were 5 percentage points higher when clinicians systematically explored patients’ sound preferences during consultations. The studies covered 42 clinics in Spain, the United States and Canada, but the reported findings do not establish that the approach alone caused the difference.
WSA says hearing aid conversion rates were 5 percentage points higher when hearing care professionals systematically explored patients’ individual sound preferences during consultations, according to results from studies at 42 clinics in Spain, the United States and Canada. The findings suggest that discussing how patients want sound to be presented may be associated with their decision to purchase hearing aids, although the reported results do not establish that the discussions caused the increase.
Over more than three months, 63 hearing care professionals used WSA’s Sound Preference tool and a follow-up discussion with new and experienced hearing aid users. The group included 43 professionals in Spain and 20 across the United States and Canada. The overall result combined findings from the Spanish and North American studies.
WSA reported a 4.3-percentage-point advantage in the Spanish study and a 5.8-percentage-point advantage in North America. The source describes these as differences in conversion rates, not relative percentage increases. It does not give the underlying conversion rates, participant totals or enough methodological detail to assess how the studies handled other factors that can affect purchasing decisions.
The tool lets patients compare natural and enhanced sound designs across five listening scenarios and discuss what they prefer with a clinician. In the Spanish study, about 40% of clients expressed a moderate or strong preference for one design; preferences were split approximately evenly between natural and enhanced sound. WSA also reported that 84% of Spanish clinicians agreed the approach improved the clinical experience they could offer, while 77% agreed it improved the likelihood of selecting the right hearing aid.
How Preference Talks May Affect Purchases
The reported difference matters to hearing care providers because it connects a consultation practice—asking patients to compare and describe sound—with a measure of whether clients proceed to buy hearing aids. The results also point to a possible benefit beyond sales: clinicians said the process gave patients more involvement in choosing a device and made the discussion more collaborative.
For patients, sound preference discussions offer a way to describe listening experiences that may not be captured by clinical measurements alone. However, the results should be read as an association reported by WSA, not proof that the tool itself produces higher conversion. The source does not report whether the difference persisted over time, whether participants continued using their devices, or how the approach affected hearing outcomes.

WSA’s Sound Preference Program
The studies build on WSA Sound Preference, a global program launched in April, according to the report. It provides research and clinical tools intended to help hearing care professionals explore how patients’ preferred sound experiences relate to hearing aid selection. The Spanish study is described in a white paper by Laura Winther Balling, Ingrid Rubio Roldán and José Antonio Navarrete Salmerón.
WSA links the findings to its strategy of offering distinct sound designs through its Widex and Signia brands. The report describes Widex Allure AI as aimed at listeners who prefer natural sound and Signia Multi-adaptive Xperience as emphasizing speech clarity and comfort in complex listening environments. These product descriptions are provided by WSA; the study results presented in the report do not establish that either product is superior or that a particular sound preference improves clinical outcomes.
Study Methods and Outcomes Not Reported
The available report does not provide the full study protocols, baseline conversion rates, participant counts for each study, or details about how clinics or patients were selected. It is not clear whether clinics used a comparison group, how conversion was defined, or whether factors such as price, insurance coverage, follow-up practices and local purchasing patterns were accounted for. Those details are needed to judge how broadly the findings apply and whether the observed difference can be attributed to the preference discussions.
The report also does not describe long-term outcomes, including device use, satisfaction after fitting or changes in hearing-related quality of life. The clinician survey results reflect reported agreement, not an independent measurement of patient outcomes. The figures and product characterizations are attributed to WSA and the reporting on its studies.
Further Evidence and Clinical Use
WSA says the findings support continuing its Sound Preference program and maintaining distinct sound design options. Hearing care professionals may use the comparison tool as one part of a consultation, with clinical judgment and individual hearing needs still guiding the final recommendation. The report does not announce a separate next study or provide a timeline for additional results.
The Spanish findings are available in a white paper by Balling, Rubio Roldán and Navarrete Salmerón. Further independent research with published methods, comparison groups and longer-term patient outcomes would help clarify whether structured preference discussions consistently affect purchasing decisions and what benefits patients experience after fitting.
Key Questions
What did the WSA studies find?
WSA reported that hearing aid conversion rates were 5 percentage points higher overall when clinicians systematically explored sound preferences. The reported advantages were 4.3 percentage points in Spain and 5.8 percentage points in North America.
Where and how long were the studies conducted?
The studies involved 42 clinics in Spain, the United States and Canada and lasted more than three months. A total of 63 hearing care professionals used the preference tool and held follow-up discussions.
Does the research prove that sound preference discussions cause more purchases?
No. The report describes higher conversion rates associated with the approach, but the available information does not establish cause and effect or provide enough methodological detail to rule out other explanations.
What does the Sound Preference tool do?
It allows patients to compare natural and enhanced sound designs across five listening scenarios, then discuss their preferences with a hearing care professional. The clinician considers those preferences alongside hearing needs and other fitting requirements.
