What Decibel Level Should You Wear Ear Protection?

As we are exposed to various kinds of noises on a daily basis, it is crucial to protect our ears from the harmful effects of loud sounds. One of the most effective ways of doing this is by wearing ear protection. But the question arises, at what decibel level should we start using it? In this discussion, we’ll delve into different decibel levels and suggest what ear protection is suitable for each.

Understanding Decibels and Hearing Loss

Noise-induced hearing loss (NIHL) is a serious and irreversible condition that affects millions of people worldwide. It occurs when exposure to loud sounds damages the hair cells in the inner ear, leading to hearing loss and tinnitus. The level of noise that causes hearing damage is measured in decibels (dB). The higher the decibel level, the louder the sound, and the shorter the amount of time it takes for hearing damage to occur.

The Safe Decibel Level

The Occupational Safety and Health Administration (OSHA) recommends that workers do not expose themselves to noise levels above 85 dB for more than eight hours a day. However, exposure to noise levels above 110 dB for even a few minutes can cause permanent hearing damage.

Types of Ear Protection

There are many types of ear protection devices available, including earplugs, earmuffs, and specialized headphones. The choice of ear protection depends on several factors, including the noise level, the duration of exposure, and personal preferences.

One key takeaway from this text is the importance of understanding decibel levels and choosing the appropriate ear protection to prevent hearing loss. Exposure to noise levels above 85 dB for extended periods of time can cause irreversible hearing damage, and even short exposure to levels above 110 dB can lead to permanent hearing loss. Ear protection devices such as earplugs, earmuffs, and specialized headphones can help to reduce the impact of loud noises on the ears, but it is important to consider factors such as comfort, durability, and noise reduction effectiveness when choosing the right type of protection.


Earplugs are small devices that fit inside the ear canal, forming a seal that blocks out noise. They come in various shapes and sizes and can be made of foam, silicone, or wax. Earplugs are often used in noisy environments, such as construction sites or concerts.


Earmuffs are larger devices that fit over the ears, forming a seal that blocks out noise. They are usually made of hard plastic and foam and are worn over the head like a pair of headphones. Earmuffs are often used in industrial settings or when operating loud machinery.

Specialized Headphones

Specialized headphones, such as noise-cancelling headphones, are designed to reduce the level of outside noise. They work by creating an anti-noise signal that cancels out the incoming noise. These headphones are often used in noisy environments like airplanes or trains.

Factors to Consider When Choosing Ear Protection

When choosing ear protection, several factors should be considered, including comfort, durability, and noise reduction effectiveness. It is important to choose ear protection that fits well and does not cause discomfort, as poorly fitting ear protection can cause irritation or even damage to the ear canal.

Noise Reduction Effectiveness

The noise reduction effectiveness of ear protection is measured in decibels, and it is important to choose ear protection that provides adequate protection for the noise level in question. For example, if you are working in a noisy environment with a decibel level of 100 dB, you should choose ear protection that reduces the noise level to below 85 dB.

Comfort and Durability

Ear protection should be comfortable and durable. Discomfort or irritation can lead to the removal of the ear protection, leaving the ears exposed to harmful noise levels. Durability is also important, as ear protection that wears out quickly will need to be replaced frequently.

FAQs – What DB Should You Wear Ear Protection

What is considered a dangerous noise level?

Noise exposure becomes dangerous when it exceeds 85 decibels (dB) for an extended period. People working or spending time in a noisy environment above 85 dB for 8 hours are considered at risk of hearing damage. Every 3 decibels increases the noise exposure levels that can trigger hearing damage by two times.

When should you wear ear protection?

Earplugs or earmuffs should be worn when you are in areas where the noise level exceeds 85 dB, especially if it persists for a prolonged period. Examples include loud music concerts, shooting ranges, construction sites, airports, woodworking shops, nail salons, or riding a motorcycle.

What types of ear protection are there?

There are two types of ear protection – earplugs and earmuffs. Earplugs are disposable or reusable foam plugs that are placed inside your ear canal, sealing out the noise. Earmuffs are designed to cover the outer ear and can be adjusted to fit a person’s head.

Can earplugs damage my ears?

Earplugs, if inserted correctly and used according to the manufacturer’s instructions, will not damage your ears. Improper insertion, over insertion or frequency of use may cause damage to the ear canal such as an earwax buildup or ear infection, but if used correctly, earplugs are safe.

What are signs of hearing loss?

Listening to loud noises for an extended period can lead to hearing loss. Some signs of hearing loss include a feeling of fullness in the ears, tinnitus or a ringing in the ears, difficulty hearing in noisy environments, or having to turn up the volume on devices to hear correctly. Getting a regular hearing test is recommended to monitor your hearing health.
