Noise blocking during NC machining, noise blocking during ballistic machining

Work noise generated at the site is quite large, but 3M company products are highly soundproof, the noise of the unpleasant grinder is also reduced, and the workers' evaluation is also high, so I have been using it all the time.

Because the restoration time when crushing is long, it is easy to put it in your ear. Sound insulation is also quite different from things sold at Daiso.
Used during sleep.

Even with wearing, there was no sense of oppression, and the soundproofing effect was satisfactory somewhat. I plan to purchase it next time.

There is no problem as an earplug. We will also purchase.
Sound insulation when using Thunder

The best thing purchased this time is this This is reasonable hardness and the time to return Since the surface is not smooth, it will stay in the same place for a long time Sound insulation is also satisfactory

It's easy to use because it's not too hard and not too soft. It also shuts out the noise firmly.

Since I used the same product for a long time and it deteriorated, I bought it.
When going to bed

I can sleep well because it cuts off in a good condition as it is hard to remove and the sound is good.

It fits tightly and interrupts the sound. Although it is a repeat, it lasts longer than other similar sponge types.

Because the rebound is somewhat strong, it can be made small by crushing strongly (じ じ る), but if you do not put it in your ear quickly it will inflate before you insert it all the way back. However, it is possible to use it without trouble if it matches timing and even timing. Since the material is soft, it does not feel stress at all even if it is in the ear, so it will not feel stress or feel pain even after long-term use. The durability is more than the price of goods. (The durability is high for 100%)
