Silicone Earplugs
Used for both sound reduction and keeping water out of the ear. They are reusable and can be cleaned. The NRR varies depending on the fit but usually offers moderate protection.
Earmuffs
Used for high noise environments such as airports and shooting ranges. They provide an NRR of around 20 to 30 decibels.
Active Noise Cancelling Headphones
These are used for listening to music, traveling on airplanes, or in office environments, where they cancel out ambient noise using active noise control. The level of protection is not measured in NRR but can be substantial for low-frequency noise.
Foam Earplugs
Usage for general noise reduction, such as sleeping or studying. They provide a Noise Reduction Rating (NRR) of approximately 25 to 33 decibels.
Passive Earplugs
Generic noise-blockers used for sleeping or in loud environments like factories. They provide average noise reduction without electronic components. NRR ranges from 22 to 33 decibels.
Helmet-Mounted Earmuffs
Used with safety helmets for construction, logging, or mining, providing hearing protection without compromising head protection. NRR varies but usually ranges from 20 to 30 decibels.
Wax Earplugs
Usage for swimming to prevent water entry, as well as noise reduction. They mold to the shape of the ear and provide variable NRR depending on fit.
Electronic Earmuffs
Used for environments where communication is necessary amidst noise, such as on construction sites. They allow for normal conversation while blocking loud sounds. Protection level is similar to regular earmuffs.
Canal Caps
Used for intermittent noise exposure as they can be easily put on and removed. They have an NRR of approximately 17 to 25 decibels.
Sound Attenuation Earplugs
These earplugs, often used by musicians and sound engineers, attenuate all frequencies almost equally without distorting the sound quality. NRR can range from 12 to 20 decibels.
Communication Headsets
Used in industries where verbal communication is imperative amongst noise, such as aviation or military. These often have an NRR of 20 to 30 decibels while allowing for clear communication.
Banded Earplugs
Ideal for workers moving in and out of noisy areas, as they can be easily positioned around the neck when not in use. NRR typically ranges from 10 to 20 decibels.
Flanged Earplugs
Used for musicians and concert attendees, providing a relatively flat response to preserve sound quality while lowering volume. NRR varies but typically around 15 to 25 decibels.
Custom Molded Earplugs
These are made for the individual wearer's ear canal, used by professionals exposed to noise regularly. NRR depends on fit but can be quite high.
Reusable Earplugs
These earplugs provide a cost-effective solution for repeated exposure to noise. The NRR typically spans from 23 to 27 decibels, depending on proper fit and cleanliness.
