disposable earplugs

The crew gave me disposable earplugs and directed me to a seat made of webbing.

Since the noise levels in industrial laundries can be quite high, earmuffs and disposable earplugs are often issued.

The asphalt in front of the building was strewn with disposable earplugs, which the mechanics wore so they wouldn't go deaf from the rivet guns.

This small pack, of course, will allow you only the minimum: a guidebook, a pair of sandals, standard hygiene items, a few relevant medicines (including sunscreen), disposable earplugs (for those inevitable noisy environments), and some small gift items for your future hosts and friends.
