Model No. QZ313A. Comfortable. Noise reducing. Sleep; Study; Work; Power tools; Loud events; Concerts. Noise Reduction Rating: 32 decibels. Sound Attenuation Data: 125 Hz Frequency: 39.3 dB mean attenuation; 3.9 dB standard deviation. 250 Hz Frequency: 41.1 dB mean attenuation; 4.8 dB standard deviation. 500 Hz Frequency: 41.8 dB mean attenuation; 4.7 dB standard deviation. 1000 Hz Frequency: 38.7 dB mean attenuation; 3.7 dB standard deviation. 2000 Hz Frequency: 39.9 dB mean attenuation; 3.8 dB standard deviation. 3150 Hz Frequency: 46.5 dB mean attenuation; 3.2 dB standard deviation. 4000 Hz Frequency: 47.5 dB mean attenuation; 3.7 dB standard deviation. 6300 Hz Frequency: 49.9 dB mean attenuation; 4.1 dB standard deviation. 8000 Hz Frequency: 50.1 dB mean attenuation; 3.3 dB standard deviation. The level of noise entering a person's ear, when hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR. Example: 1. The environmental noise level as measured at the ear is 92 dBA. 2. The NRR is (32) decibels (dB). 3. The level of noise entering the ear canal is approximately equal to (92 dB [A]-32 NRR) dB(A). Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the noise reduction rating (32) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire. Noise Reduction Rating: 32 decibels (when used as directed). The range of noise reduction rating for existing hearing protectors is approximately 0-30 (high numbers denote greater effectiveness).

For noise environments dominated by frequencies below 500 Hz the C-weighted environmental noise level should be used. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit.
