Last night around 2:30am a huge firecracker, shot into the sky, wen't off. It was LOUD. I was probably 15 feet from my front door, where windows were open (all condos here use ocean breeze as A.C so we all have windows open) and it startled me. It's dead quiet outside. I estimate the firecracker got launched somewhere between 70-100 feet from the front door. Does anyone know with say a 150db firecracker at what range it would drop to levels not causing a problem? I wouldn't typically think this was an issue, but after the event and going to bed, I woke up to a pressure in my ears, which is upsetting my greatly. I'm concerned this is hearing loss, as pressure in the ear can be the feeling when you've had severe hearing loss. Since my ears are already in a bad place trying to recovery from 2 months ago, I'm panicking that this sent my ears over the edge. I'm just utterly stunned this could of caused me a problem.
