Leader Soft Foam Earplugs 10 ea

Q1441A Comfortably contours to ears. Soft protection from harmful noise. Blocks noise from snoring. Not made with natural rubber latex. Snoring. Studying. Working. Sports. Power tools. Noise Reduction: 32 decibels (when used as directed). The range of noise reduction rating for existing hearing protectors is approximately 0 to 30 (High numbers denote greater effectiveness). Sound Attenuation Data: 125 Frequency Hz: 37.3 mean attenuation, dB; 5.9 standard deviation, dB; 32 NRR. 250 Frequency Hz: 40.8 mean attenuation, dB; 5.3 standard deviation, dB; 32 NRR. 500 Frequency Hz: 43.1 mean attenuation, dB; 5.0 standard deviation, dB; 32 NRR. 1000 Frequency Hz: 41.6 mean attenuation, dB; 4.8 standard deviation, dB; 32 NRR. 2000 Frequency Hz: 40.7 mean attenuation, dB; 2.8 standard deviation, dB; 32 NRR. 3150 Frequency Hz: 45.6 mean attenuation, dB; 4.2 standard deviation, dB; 32 NRR. 4000 Frequency Hz: 46.2 mean attenuation, dB; 4.2 standard deviation, dB; 32 NRR. 6300 Frequency Hz: 49.4 mean attenuation, dB; 4.4 standard deviation, dB; 32 NRR. 8000 Frequency Hz: 48.3 mean attenuation, dB; 4.5 standard deviation, dB; 32 NRR. 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 is approximately equal to [92 dB(A)-32 NRR] dB(A).
