Already did all of those things. Even Yoast is set to say Sound advice Audiology. The only thing I found was the NPI record says Sound Advice Hearing Aids & Audiology.You may wish to conduct a search on the keywords "Sound Advice Hearing" to identify the source. Could be at one of they many citations out there. If you find it submit a request to correct your business name or if you are able to do so self manage it. Double check all of your website content to make sure that your business name is not reflected as "Sound Advice Hearing" in any of your content, front end or back end. I hope this is helpful to you.
