TEST RESULT: NRR 26dB up to 125dB

• Lab Code 100427-0
• Attenuation measurements have been performed according to the American National Standards Institute (ANSI) Specifications, ANSI 3.19-1974, using the experimenter-fit protocol, on the G&F Products Model 12010/BL, 12010/BU earmuff (test ID Q3991A). The specified threshold measurement data were obtained using ten normally-hearing listeners, six male, and four female. These listeners were selected from a standby group of about 35 volunteers who regularly serve as listeners for measurements of this kind.
• The measurements were made in a room designed for this purpose. All acoustic characteristics of the room meet the requirements outlined in ANSI 3.19-1974. The ambient noise levels in this room are below the limits specified in ANSI 3.19-1974, and open ear thresholds are used on a continuing basis to monitor the background noise levels. An automatic recording attenuator was used to record both open and occluded ear thresholds.
• Each of the ten subjects was tested three times at each of nine test frequencies. The attached Tables show grand mean attenuation values in decibels (dB) for each test signal along with group attenuation values. Standard deviations (S.D.) for the 30 different attenuation determinations for each test signal are also given. The results presented in this report pertain to the samples tested only.

Disclaimer: Use these laboratory-derived attenuation data for comparison purposes only. The amount of protection afforded in-field use is often significantly lower depending on how the protectors are fitted and worn.

Power machine is too powerful and too loud, must get the ear protected while getting work done

NRR SOUND TECHNOLOGY

Designed with noise-dampening sponge, soft ear cushions and solid ABS ear cups that seal around your ears, our toddler ear protection ensures NRR (Noise Reduction Rating) 26dB for noise reduction. Protect you and your child's hearing by blocking out the noise of monster jam/ monster trucks, hunting season, sports events, concerts, Disneyland, airplane flights.

Advantages of a good noise reduction earmuff:

• less attenuation variability among users
• designed so that one size fits most head sizes
• easily seen at a distance to assist in the monitoring of their use
• not easily misplaced or lost
• maybe worn with minor ear infections

Adjustable headband fits Men, Women and little ones

WHY DO WE NEED NOISE REDUCTION EARMUFFS

People should wear a hearing protector if the noise or sound level at the workplace exceeds 85 decibels (A-weighted) or dBA. Hearing protectors reduce the noise exposure level and the risk of hearing loss.

If hearing protection is required, then a complete hearing conservation program should be implemented. A hearing conservation program includes noise assessment, hearing protector selection, employee training, and education, audiometric testing, maintenance, inspection, record keeping, and program evaluation.

The effectiveness of hearing protection is reduced greatly if the hearing protectors do not fit properly, if they are worn only periodically, or if they are removed even for a short period of time. To maintain their effectiveness, hearing protection should not be modified. Radio/music earphones or headsets are not substitutes for hearing protectors and should not be worn where hearing protectors are required to protect against exposure to noise.

Select hearing protection that is:

• Provides adequate protection.
• Compatible with other required personal protective equipment, or communication devices.
• Comfortable enough to be accepted and worn.
• Appropriate for the temperature and humidity in the workplace.
• Able to provide adequate communication and audibility needs (e.g., the ability to hear alarms or warning sounds).
