SLEEP PLUGS TEMPERED FOAM: The earplugs are made of tempered foam and are mainly applied to the body without pressure points. This is a very important feature since there many delicate nerves in the auditory canal. Lingering pressure on the nerves can be very sensitive during a night of seven to eight hours of sleep. The compacted surface ensures that there no wax sticks to the plug or in the foam. Therefore, they can be easily cleaned with a damp cloth and reused. The SNR (Sound Noise Reduction) of these earplugs is a high 34 dB. Over 120 dB can lead to hearing loss immediately. Under normal circumstances, the ear can withstand 80 dB for approximately 8 hours. With each increase of 3 dB, the time is halved. Earplugs with a high SNR provide protection from noises while sleeping-a connection that is linked to the circulatory system of your own body and is often very disturbing.
