Hearing Protection

Noise-induced hearing loss is a common workplace injury that is 100% preventable. Protective Industrial Products is proud to offer a complete line of hearing protection options to keep workers protected from loud working environments, while achieving all-day comfort and optimal sound attenuation.

Electronic Ear Muff

Ear Muffs

Ear Muffs provide a more secure form of hearing protection, especially because they are easier to use and allow the user to gain maximum protection from the product.


All hearing protection methods have capability to reduce noise. Devices with only this function are called passive hearing protectors. Electronic styles integrate advanced electronics with the ear muffs to suit multiple work environments.

PASSIVE EAR MUFFS - Noise blocking muffs attenuate noise using the highest quality insulating and dampening materials and are offered in multiple levels of protection to fit your working environment. Slim profile increases stability and reduces the risk of snagging in confined areas • Available in Headband, Cap Mounted and Neckband Styles


When combining hearing protection with other protective equipment it is important that the hearing protection attenuation is not impaired due to the combination. For example the temples of safety eyewear should be of a low profile type to minimize the reduction of performance. If you are uncertain if your other equipment will affect the attenuation it may be wise to choose an ear muff with a slightly higher protection level than what the analyze method is stating.

  • headband style ear muff

    Electronic & Passive
    Light, durable construction with easy size adjustment provides the perfect fit for all head sizes. Unlike other ear muffs on the market, our line is made with a high performance, thermoplastic material that allows the headband to be stretched without warping or distorting.

  • hard hat mounted ear muff

    Electronic & Passive
    Fits most cap-style hard hats with universal slots. They can be worn snapped into place on the ear, slightly off the ear to allow hearing, or pivoted up and away when not needed.

  • neckband ear muff

    Passive Only
    For use in conjunction with bump caps, hard hats without universal slots or head-mounted face protection. Adjustable head support strap ensures that muffs stay in position at all times.

NRR Rating

When selecting hearing protection you need information on the character of the noise; sound pressure level (dB), duration and frequency content (Hz). The level of the disturbing noise and its frequency distribution is of great importance. High levels of low frequency noise have the inconvenience of making it difficult to understand speech (below 500Hz).

A product's Noise Reduction Rating, or NRR, measures the effectiveness of a hearing protector to decrease exposure to sounds. The higher the rating, the stronger the protection. While it is important to offer workers enough protection, it is actually dangerous to over protect them as well. If the NRR rating is too high for the environment (specifically, levels below 70dB), difficulties with communication and hearing warning signals. It will cause the user to feel isolated and to remove the hearing protector.

Ear Plugs

Ear plugs are a popular choice because they are seen as the most economical solution, and they can easily be worn with other PPE.

SINGLE USE EAR PLUGS - Comfortable, soft foam plugs that are commonly used and hygienic, ideal for high contamination environments and for workplace visitors

Materials Basics

Using ear plugs should be comfortable. From traditional to innovative, the materials that make up our plugs are designed for excellent performance during the task at hand, while avoiding discomfort after long periods of use.

  • polyurethane ear plugs

    Our soft polyurethane foam has a unique cellular structure that allows for slow expansion to perfectly fit the size and form of the ear canal, with a sealed surface that prevents foreign bodies from penetrating. The material provides high and immediate noise reduction.

  • thermoplastic elastomer ear plugs

    The smooth, dirt-repellent surface of TPE plugs can be cleaned using soap and water. This is ideal for dirty working environments, preventing minor injuries and irritation. It is created in a pre-formed shape and requires no rolling, making them easy to put on. Its moderate noise reduction blocks out hazardous noise yet allows warning signals and voices to be clearly understood.

  • pvc ear plugs

    A more traditional material for ear plugs, soft PVC foam provides high and immediate noise reduction.

Shape & Fit

The shape of the ear plug is designed to bring the wearer maximum comfort. They are tailored to best fit the ear canal and deliver optimal attenuation.

  • bullet style

    Tapered Bullet
    Fits to the natural contour of the ear canal

  • compact tapered style

    Compact Tapered Bullet
    Perfect size for users with narrow ear canals

  • Tapered Flare style

    Tapered Flare
    Reduces risk of back out of ear canal

  • Tapered Flare style

    Easy insertion and removal from ear canal

  • cylindrical style

    Classic design, proven favorite for many workers

  • flange classic style

    Proven design for comfort and optimal attenuation

  • flange/disc combo

    No rolling or pinching required. Just insert and twist

Plug Styles

These features help tailor a product to be safer and more convenient in a specific working environment, whether that means fitting in a dispenser or keeping track of plugs after removing them from the ear.

  • uncorded ear plug style

    The most economical option, and mainly for one time use. Also practical in areas where a cord may be hazardous.

  • corded ear plug style

    Easier to keep track of by allowing the user to wear the plugs around their neck while not in use. Can be made with rubber or non-resonating textiles, and certain styles are detachable for added safety.

  • headband ear plug style

    Convenient for intermittent use. Ensures out of the way comfort and limits contact with clothing and resulting sound transmission. Prevents the plugs from contact with dirty surfaces when set down.
