Guide to earplugs and ear protectors: types, uses and tips


Earplugs and hearing protectors are essential items to preserve our hearing in situations of exposure to noise, water or humidity. It is important to protect and care for your hearing in a comfortable and practical way. In this guide, we will explore the different types of earplugs for hearing protection available, as well as their applications and how to choose the right ones for your needs.

Types of earplugs by material

The choice of earplug material plays a crucial role in their effectiveness and comfort. Below, we will explore the different types of earplugs according to the material they are made of and the situations in which they are most suitable:

Wax earplugs

Wax earplugs, although uncommon, are noted for their versatility, comfort and low likelihood of causing allergies. These earplugs fit snugly in the ear and are ideal for prolonged use, especially during sleep, due to their ability to continuously adapt to the ear canal.

Silicone earplugs

Silicone earplugs fit easily in the ear canal and are especially recommended for use during sleep. They are easy to insert and remove, forming an airtight seal on the outside of the ear canal for efficient protection. Within the silicone earplugs category, some are more mouldable and are made of soft silicone, making them hypoallergenic.

They use ergonomic design and advanced noise cancelling technology to effectively block unwanted ambient noise such as snoring. These earplugs ensure a restful and undisturbed sleep, making them the ideal solution for improving sleep quality and enjoying a noise-free environment.

Swimming earplugs

Swimming and pool earplugs are essential accessories for those who enjoy water activities. Designed specifically to protect the ears from water, earplugs for swimmers are highly effective in preventing fluid from entering the ear canal. Made of high quality waterproof materials, such as silicone, they ensure a tight seal that keeps water out, thus reducing the risk of infections and otitis externa. Swimming earplugs are the ideal choice for those who want to enjoy their favourite water activities without worrying about potential ear problems, providing reliable protection and comfort in the water.

Shooting earplugs

Shooting and hunting earplugs are an essential tool for those who participate in activities that involve shooting. These earplugs are designed with a focus on hearing protection, reducing noise levels to safe levels without compromising communication or perception of the environment. Some models are equipped with noise-cancelling technology that instantly muffles the sounds of intense gunfire, providing a more comfortable and safer experience. Hunters and shooters can choose between reusable and disposable earplugs according to their specific needs.

Surf earplugs

Surfing earplugs are crucial elements in hearing protection for those who enjoy water sports such as surfing, kitesurfing and swimming in the sea or pool. These earplugs play an essential role in preventing ear infections and the dreaded "exostosis" or "surfer's ear", a medical condition resulting from abnormal bone growth in the ear canal due to repeated exposure to cold, salt water. This condition can lead to hearing problems and, in severe cases, even require surgery. Surf earplugs, designed specifically for this purpose, effectively protect the ear from the ingress of water, cold air, dirt and bacteria present in the water, while allowing for proper hearing and effective communication in the aquatic environment. They are comfortable, mouldable and available in a variety of styles and materials, making them a smart choice for maintaining optimal hearing health when playing water sports.

Earplugs for work

Earplugs for work are essential devices in noisy work environments where hearing protection is essential. These earplugs, also known as ear protectors or earmuffs, are specifically designed to completely isolate noise, ensuring the hearing safety of workers. Their use is mandatory in accordance with occupational safety regulations, such as Royal Decree 286/2006, which establishes preventive and control measures for the protection of the health of employees in places where daily noise levels exceed 85 dB. Work earplugs, available from various brands such as 3M, offer an effective barrier against constant noise and provide comfort during long working hours. Making the right choice from the different types of earplugs and ear protectors available on the market ensures that workers are optimally protected against the harmful effects of noise in the workplace.

Earplugs for concerts

Earplugs for concerts are an essential accessory for live music lovers. They are specifically designed to protect the hearing of people attending concerts, festivals and live music events, where sound levels can reach potentially damaging levels for the human ear.

In addition to their pressure equalisation function, these earplugs feature a special filter that attenuates unpleasant noises present during the flight, providing a more comfortable and quieter ride. Ear pressure, which can be uncomfortable during take-off and landing, is carefully controlled, thanks to the pressure equalisation filters, which reduce the noise levels of the aircraft's engine and turbine. These earplugs offer high wearing comfort and exceptional sound quality, as well as acting as an effective passive noise insulator. They are ideal for frequent flyers who want to protect their hearing and enjoy an undisturbed flight.

Diving earplugs

When it comes to water activities such as scuba diving, ear protection is essential, as water can enter and cause discomfort or even ear infections. For those who enjoy exploring the deep sea or simply swimming on the surface, earplugs designed specifically for water are a key solution. These earplugs allow for a comfortable experience by eliminating the sensation of clogged ears while preventing water from entering the ear canal. In addition, for more experienced divers who face significant pressure changes during their dives, these earplugs offer additional relief by allowing the ears to compensate naturally without putting the eardrum at risk. These earplugs are recommended by water sports doctors and help to maintain the pH balance in the ear, thus preventing possible infections.

Earplugs for autism

Earplugs for autism are specialized hearing protection devices designed to provide sensory relief and comfort to individuals on the autism spectrum who may experience heightened sensitivity to noise and auditory stimuli. These earplugs are crafted with the unique needs of autistic individuals in mind, offering a means to regulate and control their exposure to sound in various environments. They come in a variety of shapes and sizes, designed to fit comfortably and securely in the ears. Earplugs for autism can be especially beneficial in situations where sensory overload can occur, such as crowded places, loud events, or during periods of heightened stress or anxiety. By offering a way to manage auditory stimuli, these earplugs can contribute to a more controlled and soothing sensory experience for individuals with autism, helping them better navigate their surroundings and improve their overall well-being.

How to choose the right earplugs

1. Level of protection needed

Determine the amount of hearing protection you need based on noise exposure. Earplugs with a high level of attenuation are ideal for very noisy environments.

2. Comfort

Comfort is critical, especially if you plan to wear your earplugs for long periods of time. Custom-made earplugs are often the most comfortable, as they fit snugly in your ear.

3. Durability

If you're looking for a long-term solution, choose durable, long-lasting earplugs. Materials such as silicone and rubber tend to be more durable than foam.

4. Intended use

Consider the context in which you will use the earplugs and choose a type that suits your specific needs, whether for swimming, sleeping, work or sports.

  5. Store them properly: Store earplugs in a clean, dry case when not in use to avoid contamination.

By following these regular cleaning steps, your earplugs will stay in good condition and provide the protection you need for longer.

Are earplugs bad for your ears?

Earplugs themselves are not inherently bad, but improper or excessive use can have negative effects. On the one hand, earplugs are useful tools to protect the ears from excessive noise, water or wind, and are especially beneficial in noisy environments or during water activities. However, excessive or improper use can lead to problems such as earwax build-up, ear infections or injury if not applied correctly. In addition, using earplugs with the volume of music at dangerously high levels can increase the risk of hearing damage. In summary, earplugs are beneficial when used properly for their intended purpose, but it is important to follow the recommendations and guidelines to avoid potential complications.

How many decibels can earplugs block?

The extent to which earplugs can block decibels depends on various factors, including the type of earplugs, their design, and how well they fit in the ears. On average, most earplugs can provide a noise reduction of 15 to 35 decibels (dB). Foam earplugs, for instance, can offer around 30 dB of noise reduction, making them effective for reducing sound levels in everyday situations. However, custom-molded earplugs, designed to fit precisely to an individual's ear canal, can achieve even higher levels of noise reduction, often exceeding 35 dB. It's important to note that proper insertion and a secure fit play a crucial role in maximizing the effectiveness of earplugs. Additionally, the specific noise reduction rating (NRR) of earplugs should be considered, as it provides a standardized measure of their noise-blocking capabilities. Ultimately, the choice of earplugs should align with the level of noise reduction required for a given environment or activity.
