I'm Ernest, the author behind Audio Tech knowledge. I began researching the health implications of head-phones in our ears since 2018 out of concern for my daughter who's almost 24 hours with ear-phone on her ears. I started the website to help others learn more about why having sounds constantly on our ears may not be healthy and how to minimize harmful exposure in their daily lives or later in their lives. With all the latest technologies, I've been delighted by how much Audio-Tech Knowledge has grown in such a short period of time and I'm looking forward to continuing to share and more information with you about this important topic.
