Is there something wrong with my ear?

I keep hearing a buzzing noise every now and again this morning for some reason. It happens in usually 4 or 5 short bursts. Not very loud. But its happened a bit now. Sounds like zzzt zzzt zzzt zzzt. Thats the best I can describe it phonetically I guess.

I was trying to find out what this was online, I’m hoping that it isn’t a bug of some sort inside my ear.
