Sounds like you're still buzzing.
I wear earplugs unless it's just gently pottering through town. Disposable plugs bought by the hundreds are really cheap while the same plugs bought individually are extortionate. Custom moulded plugs (with or without earphones) can be really effective - unfortunately I didn't get told that they don't suit everybody's ears until after I'd paid serious money for them and just about deafened myself! Back to yellow foam cylinders for me.
I use a silicone rollup disposable plug since they feel better in my ears after wearing them all day. Inexpensive when purchased by the case.
Here is exactly the plugs I use when I use plug. I have tried many things over the years because of very noisy hobbies; sound cancelling headphones, custom mold fitting ear plugs, cheap rollup foam plugs, cigarette filters (in an emergency), rolled up t-shirt strips (also emergency method), and finally when I found these they allow me to wear them all day without discomfort and additional headphones can be used over them comfortable (necessary with cannon fire).

These are inexpensive when purchased by the case(lots of 100 or lots of 200) and can be dispensed to your passengers and discarded without thought as to expense.
