Ear Plugs for Hearing Protection: How to Choose and Use Them

Exposure to loud noise can damage hearing, sometimes permanently. Earplugs are a convenient way to reduce the amount of sound reaching your ears at work, at concerts, while travelling or when using noisy equipment. The right choice depends on the noise, how long you will be exposed to it and how well the plugs fit.

When should you use hearing protection?

Consider hearing protection when you need to raise your voice to speak to someone about two metres away, or when noise leaves your ears ringing or your hearing feeling muffled afterwards. These can be warning signs that sound levels are too high.

In the UK, workplace noise regulations set daily or weekly exposure action values at 80 and 85 decibels (dB), with an exposure limit value of 87 dB at the ear after taking hearing protection into account. Employers have responsibilities to assess and control workplace noise, and to provide suitable protection where required. Earplugs should not be used as a substitute for reducing noise at its source where that is reasonably practicable.

Types of earplugs

• Foam earplugs: Disposable plugs that expand in the ear canal. They can provide substantial noise reduction when inserted correctly.
• Pre-moulded reusable earplugs: Usually made from silicone or a similar material. They can be easier to fit and clean, but must be maintained according to the manufacturer’s instructions.
• Filtered earplugs: Designed to reduce sound more evenly across different frequencies. They may suit musicians and concert-goers who want to lower volume while retaining greater sound clarity.
• Custom-moulded earplugs: Made to fit an individual’s ears. They can be comfortable for regular use, but still need to be selected for the noise and level of protection required.
• Banded earplugs: Plugs attached to a band, which can be convenient for intermittent use. Their protection may be lower than that of correctly fitted in-ear plugs, so check the product rating.

Understanding protection ratings

Hearing protection products are often labelled with an SNR (Single Number Rating). This gives an estimate of the sound reduction provided under specified test conditions. A higher SNR does not automatically mean a product is the best choice: real-world protection depends heavily on fit, correct use and the noise environment.

For workplace use, protection should be selected as part of a noise assessment. If the plugs reduce sound too much, it may be difficult to hear speech, alarms or other important signals. Never assume that a rating alone guarantees a particular level of protection for every wearer.

How to insert foam earplugs

1. Wash and dry your hands.
2. Roll the plug between clean fingers into a narrow, crease-free cylinder. Do not simply squash the end.
3. Reach over your head with the opposite hand and gently pull the top of your ear upwards and backwards to straighten the ear canal.
4. Insert the plug gently, following the product instructions. Hold it in place while it expands.
5. Check the fit. The plug should sit securely, with only a small amount visible. If it is loose or does not reduce noise adequately, remove it and try again with a new plug.

Never force an earplug into the ear. If you are unsure about fitting, ask a hearing protection supplier or occupational health professional for guidance. Some employers can arrange fit testing to check whether a particular product works effectively for an individual wearer.

Using and caring for earplugs safely

• Follow the manufacturer’s instructions on fitting, cleaning and replacement.
• Do not reuse disposable foam plugs. Replace reusable plugs if they are damaged, dirty or no longer fit properly.
• Keep reusable plugs in a clean case when they are not being worn.
• Use earplugs designed and rated for the noise exposure. Ordinary sleep or swimming plugs may not provide suitable protection against hazardous noise.
• Make sure you can still hear alarms, instructions and traffic where necessary. If you cannot, speak to your employer or a hearing protection professional about a safer arrangement.
• Do not share earplugs.

Earplugs or earmuffs?

Earplugs are small, portable and can be worn with other protective equipment, such as a hard hat. Earmuffs may be easier to put on and check, and can be more suitable when protection needs to be removed frequently. In very noisy environments, a professional assessment may recommend using both. The correct option depends on the task, the noise level, comfort and whether the protection can be worn consistently.

When to seek advice

Stop using earplugs and seek advice if they cause pain, irritation or a feeling of blockage that does not settle. If you have ear pain, a history of ear surgery, recurring infections, a perforated eardrum or difficulty inserting plugs, speak to a healthcare professional before using in-ear protection.

Ringing in the ears or muffled hearing after noise exposure can be a sign that your ears have been overexposed. Move away from the noise and allow your ears to rest. Seek medical advice if symptoms persist, recur or are accompanied by sudden hearing loss. Sudden hearing loss should be assessed urgently.

Choosing the right earplugs

For effective hearing protection, choose a product suited to the noise and the activity, check its rating, and make sure it fits correctly every time. In workplaces, follow the noise assessment and your employer’s guidance. At concerts or other leisure events, filtered earplugs can reduce sound exposure while helping preserve sound quality. Whatever the setting, good fit and consistent use are essential.

Help reduce exposure to harmful noise

Earplugs help reduce exposure to harmful noise by lowering the volume of sound that reaches your ears. When correctly fitted and suitable for the noise level, they can help protect your hearing in loud workplaces, at concerts or while using noisy equipment. For the best protection, follow the manufacturer’s instructions and wear them consistently whenever you are exposed to hazardous noise.

Small and easy to carry

Earplugs are small, lightweight and easy to carry, making them a convenient choice for hearing protection on the go. They fit easily into a pocket, bag or key case, so you can keep a pair close at hand for concerts, travel, work or other noisy situations.

Suitable for work, concerts and travel

Earplugs are a versatile choice for hearing protection, with options suited to noisy workplaces, live music and travel. The right pair can help reduce exposure to loud machinery or concert sound, while discreet, comfortable designs are easy to carry and wear on journeys. Choose earplugs rated for the noise you expect, and make sure they fit properly; for workplace use, follow your employer’s guidance and ensure important alarms and instructions remain audible.

Available in disposable and reusable styles

Earplugs for hearing protection are available in both disposable and reusable styles, making it easy to choose an option that suits your needs. Disposable foam plugs are convenient for occasional use or when hygiene is a priority, while reusable plugs can be a practical choice for regular wear, provided they are cleaned and stored as instructed. Whatever style you choose, make sure the earplugs fit properly and are rated for the noise you need to protect against.

Can be comfortable when correctly fitted

Earplugs can be comfortable to wear when they are correctly fitted and suited to your ears. A good fit helps them sit securely without causing pressure or irritation, making them easier to keep in for longer periods. If they feel painful, loose or uncomfortable, remove them and try a different size or style, following the manufacturer’s fitting instructions.

Offer a practical alternative to earmuffs

Earplugs offer a practical alternative to earmuffs when you need hearing protection that is compact and easy to carry. They fit inside the ear, so they can be more convenient in warm conditions or when earmuffs might get in the way of other equipment, such as a hard hat or safety glasses. Choose earplugs suited to the noise level, and make sure they fit correctly to provide effective protection.

Poorly fitted earplugs may offer little protection.

Poorly fitted earplugs may offer little protection because gaps between the plug and the ear canal allow harmful noise to reach the eardrum. This is especially common when foam plugs are not rolled and inserted correctly, or when reusable plugs are the wrong size. Follow the manufacturer’s fitting instructions and check that the plugs sit securely; if they feel loose or noise still seems loud, remove them and refit or try a different size or style.

Foam plugs can be uncomfortable for some people.

Foam earplugs can feel uncomfortable for some people, particularly when worn for long periods or if they do not fit the ear canal properly. They may create pressure, irritation or a blocked sensation, so it can help to try a different size or style. If discomfort continues, remove the plugs and consider another type of hearing protection.

They may make speech and alarms harder to hear.

Earplugs reduce sound, which can make speech, warning signals and alarms harder to hear. This may affect communication or make it difficult to notice hazards, particularly in busy workplaces or near traffic. Choose protection suited to the noise and setting, and check that essential alarms and instructions remain audible. In workplaces, follow the noise assessment and your employer’s guidance.

Reusable plugs need regular cleaning.

Reusable earplugs need regular cleaning to remove earwax, dirt and moisture. If they are not cleaned and stored properly, they can become unhygienic and may irritate the ear or increase the risk of infection. Follow the manufacturer’s care instructions, and replace the plugs if they become damaged or no longer fit well.

Disposable plugs create ongoing waste.

Disposable earplugs can create ongoing waste, particularly if they are used regularly and replaced after each use. Foam plugs are often made from materials that are not accepted in household recycling, so used pairs may end up in general waste. For frequent use, reusable earplugs may be a more sustainable option, provided they are cleaned, stored and replaced in line with the manufacturer’s guidance.

Incorrect insertion can irritate the ear canal.

Incorrectly inserting earplugs can irritate or scratch the delicate skin of the ear canal, particularly if they are pushed in too far or forced into place. Poorly fitted plugs may also cause discomfort and provide less effective protection. Follow the manufacturer’s fitting instructions, use clean hands and never force an earplug into your ear.

Some plugs may reduce sound quality at concerts.

Some earplugs can make music sound less clear or balanced by reducing certain frequencies more than others. This may affect the concert experience, particularly with basic foam plugs. Filtered earplugs, designed to lower volume more evenly, can help preserve sound quality while still reducing exposure to loud noise.
