Hi. For most of my adult life whenever I hear dog bark or sometimes when somebody coughs I get this weird, and annoying, dull popping/crackling sound in my left ear. It only happens for a split second but will repeat if a dog keeps barking. I m reading some about the blown speaker effect , which sounds like an accurate description, but I can t find any good information. I m 28, white male, no health issues. Had a lot of eat infections as a child and had tubes in my ears at one point. Thanks.
