I've been hearing a buzzing sound in my ear. Is it serious?

It's probably just the wax in your ear canal that is vibrating due to the sound waves from the outside world. You can try gently pulling out any excess wax with an earbud or cotton swab, and then blowing air into your ear to help dislodge any remaining particles. If the noise persists, you should see a doctor to have it checked out.
