Deelat also offers un-corded noise reducing earplugs which are constructed with a flame-retardant, non-irritating foam that is designed to prevent moisture from accumulating. Our specially formulated PVC foam expands and contracts at a slower rate than typical foam making them much more comfortable to wear.

Hearing Protection Tools: Ear Plugs and Ear Mitts

In the construction and manufacturing industry, hearing damage is a real danger, and steps should be taken to prevent hearing loss. According to the Centers for Disease Control, four million Americans work in places where there is a risk for hearing damage. Repeated exposure to excessive noise can cause permanent hearing loss, which cannot be corrected through surgery or with hearing aids.

There are a variety of hearing protection devises on the market, like PVC earbuds, ear mitts and canal caps. These convenient and comfortable devices can be used to lower the risk for hearing loss, and they’re ideal for use in a variety of situations:

  • Loud work environments
  • At concerts and night clubs
  • At gun ranges and when hunting
  • When operating heavy machinery

How Can Noise Damage Hearing

Both one-time and repeated exposure to loud noises can cause permanent hearing loss, and loud noise degrades tiny sensory hairs in the inner ear. Over time, these hairs are damaged, and they are not regenerated. Thus, hearing loss is permanent. But how loud is too loud? The National Institute for Occupational Safety and Health suggests that workers are at risk during an eight-hour day at worksites with noise levels above 85 decibels, which is roughly equivalent to running a lawn mower.

This level can be quickly reached in a variety of situations. For instance, in construction, using a jackhammer produces 100 decibels of noise. A gunshot produces 140 decibels. And a rock concert, at its loudest, can potentially reach 150 decibels. Noise exceeding 85 decibels can be potentially damaging, and in these situations, the risk for hearing loss is high. Ear protection should be used in these situations.

You can measure sound levels using a sound level meter, but when you don’t have access to a meter, you can also estimate the noise level. Here’s a rule of thumb: Standing two to three feet away from your co-worker, if you have to raise your voice above the noise, it’s likely exceeding 85 decibels of sound.

How Effective Is Ear Prevention at Reducing Noise?

All ear protection equipment reduces noise according to an NRR rating, generally ranging between 10 and 33 decibels. This rating refers to the noise reduction at the ear, and the overall reduction is determined by subtracting 7 from the NRR number and dividing it by two. So for instance, an NRR 33 hearing protection device, like ear mitts, reduces the level by 13 decibels. If you were in a 110-decibel environment, the noise would be 97 decibels.

Ear protection devices can be used in tandem, like foam ear plugs and ear mitts. This increases the overall noise reduction. What types of noise-reducing devices work best? The key is selecting a comfortable device that is convenient to use. Common types include:

  • Ear mitts: These look similar to studio headphones, and they completely cover the ear. The biggest advantage is that proper use is simpler; they only need to be placed directly over the ear. They can also be used with foam ear plugs underneath. One disadvantage is that they are bulkier, heavier and they can get hot.
  • Foam ear plugs: These are a classic noise reduction device, and they are used by everyone from hunters, to construction works, and concert attendees. Foam plugs are made from moldable foam, they are convenient, low-cost and they’re comfortable. They’re easy to use as they slip and fit into the ear, but must be properly placed in the ear to guarantee maximum protection.
