Welcome to Hearing Insider!
Hi, I’m Dr. Jonathan Javid, Au.D.

I’ve been a full-time audiologist since 2011. Each week, I typically perform:

12 hearing aid fittings

12 hearing exams

20 hearing aid follow-up appointments

Over the years, I’ve helped more than 10,000 patients improve their hearing and quality of life. I created this site, with help from my wife, to provide a trusted online resource for people who use hearing aids or are exploring hearing solutions.

💬 Ask the Audiologist
Have a question about hearing aids or hearing loss?
I’m happy to help if I can!

I’ll reply personally if it’s something within my scope.

Note: I can't diagnose conditions or adjust hearing aids remotely, but I’ll do my best to offer useful, honest guidance.

Thanks for visiting Hearing Insider!
