Hearing protection explained: a practical guide to selection and use
Hearing protection explained: a practical guide to selection and use
Hearing protection is an important part of personal protective equipment in the workplace and workshop. Prolonged exposure to loud noises can cause permanent hearing damage, but with the right hearing protection you can work safely and comfortably all day long. The range goes from simple earplugs to advanced electronic hearing protection with integrated communication and noise filtering.
In this article you will get an overview of what to consider when choosing hearing protection, the types available and the features that can make your day-to-day work easier.
The article presents a wide selection of hearing protection covering different needs, from lightweight disposable earplugs to advanced earmuffs with active noise reduction. The aim is to provide an overview of the features, comfort and level of protection so that you can find the solution that best suits your work. The product information is based on publicly available descriptions from manufacturers and distributors, and has been summarised to provide a clear and informative overview.
Factors to consider when buying hearing protection
When choosing hearing protection, it’s not just about reducing noise as much as possible. Comfort, fit and features also play an important role in the effectiveness and comfort of using hearing protection.
1. Attenuation level (SNR value)
The attenuation of hearing protection is indicated in SNR (Single Number Rating). The higher the number, the more noise is reduced. In workplaces with high levels of machine and tool noise, an SNR value of 25–35 dB is usually recommended. It’s important not to choose hearing protection that attenuates too much, as this could make communication or hearing warning signals difficult.
2. Comfort and fit
Hearing protection should fit well, even after many hours of use. Earmuffs should have soft cushions and adjustable headbands, while earplugs should fit the size of the ear canal. Many prefer reusable silicone earplugs because they combine comfort and durability.
3. Electronic features
Electronic hearing protection can filter out harmful noise while allowing speech and ambient sounds to pass through. Some models have built-in Bluetooth so you can communicate by radio or phone without removing your hearing protection. This is especially useful in teams where cooperation and safety require constant contact.
4. Weight and ventilation
Heavy hearing protection can be uncomfortable with prolonged use. Lightweight models with good ventilation and pressure distribution reduce fatigue and sweating, increasing users’ willingness to wear them all day.
5. Maintenance and replacement
Regularly check cushions, headbands and filters for wear. Disposable earplugs should be replaced after each use, while reusable models should be cleaned regularly. Well-maintained hearing protection offers better protection and lasts longer.

Different types of hearing protection
There are several types of hearing protection, each with its own advantages depending on the work environment and personal preferences.
1. Disposable earplugs
Disposable foam earplugs are economical, lightweight and effective for short-term tasks. They expand in the ear and provide good attenuation, but may be less comfortable for prolonged use and need to be replaced frequently.
2. Reusable earplugs
These are made of silicone or rubber and can be cleaned and used several times. They are ideal for workers who need hearing protection regularly and are available in different sizes for an optimal fit.
3. Earmuffs
Earmuffs cover the entire ear and provide high attenuation. They are suitable for noisy environments such as construction sites and workshops. Many models can be worn over the head, behind the neck or mounted directly on a helmet.
4. Electronic hearing protection
Electronic models combine protection and technology. They automatically attenuate loud noises but allow speech and background sounds to pass through. Some also have radio, Bluetooth or active noise reduction, making them popular among professionals working in teams.
5. Hearing protection with communication
These models allow communication by radio or mobile phone without compromising protection. They are often used on large construction projects where coordination and safety are essential.
Different brands of hearing protection
The hearing protection market is extensive, and several manufacturers have specialised in combining safety, comfort and technology.
3M Peltor
3M Peltor is one of the best-known brands in hearing protection. They offer everything from classic earmuffs to advanced electronic models with Bluetooth and integrated communication. The products are known for their high quality and ergonomic design.
Hellberg Safety
Hellberg Safety focuses on hearing protection for professional users and offers both passive and active models. The brand emphasises comfort and compatibility with helmets and protective visors.
Honeywell Howard Leight
Honeywell manufactures a wide range of hearing protection, including both earplugs and earmuffs. The Howard Leight series is popular for its combination of effective attenuation and comfortable fit.
MSA Safety
MSA Safety offers hearing protection that is often integrated with helmet and communication systems. They are designed for demanding work environments where safety and collaboration are priorities.
Zekler
Zekler is a Scandinavian brand that combines modern design and functionality. Their electronic hearing protection is known for its ease of use and good sound quality, making it suitable for both industry and construction.
Frequently asked questions
How much should hearing protection attenuate?
It depends on the noise level in your work environment. As a general rule, the sound should be reduced to less than 80 dB in the ear. Choose hearing protection with an appropriate SNR value so that you can still communicate safely.
Can I use earplugs and earmuffs at the same time?
Yes, at extremely high noise levels you can combine earplugs and earmuffs for additional protection. This combination increases attenuation by approximately 5 dB.
How do I know if my hearing protection fits correctly?
Well-fitting hearing protection should seal without being uncomfortable. If you can hear sounds clearly or feel the protection loosening, you should adjust it or choose another model.
How often should hearing protection be replaced?
Disposable earplugs should be discarded after use, while reusable models should be replaced when they lose their shape or become damaged. Earmuffs should have new cushions at least once a year to maintain their effectiveness.
Can electronic hearing protection be used in the rain?
Most electronic hearing protection can withstand light moisture, but should not be exposed to heavy rain without protection. Always check the manufacturer’s specifications for water resistance.
