Helpful For Reducing Noises

My hubby works in a factory where there are a lot of noises. I can imagine how noisy the environment where my hubby works. Something surprised me recently. Its about my hubbys hearing. I noticed that lately his hearing has started to decrease. It really worries me. So I talked to him one day about this matter and he said he would get help. I think he went to his supervisor and that day he brought home an earplug. He said its always been there on the first aid supplies right at the factory where he worked but he was never told about this. He said a lot of workers also experienced the same problem as he had but they were also never told about this earplug.

This earplug comes in small yellow box. The earplug itself is white, made from rubber, and attached to it is a nylon string with the same yellow color. The string is to prevent one earplug to be lost or separated because they are meant to come in pair. When I tried to put these to my ears, they are comfortable enough. But I dont know if they still are when we use them for a longer period. My hubby said that this is quite helpful for reducing the noises, though. Well, its good to know that this earplug can do something to help him. I guess I dont need to worry much now.
