商品の概要

商品説明

  • NRR 32
  • Helps Block Snoring
  • Ideal for Light Sleepers
  • Trusted Since 1992

Tested according to ANSI Specs S3.19-1974

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.

Noise Reduction Rating: 32 Decibels (When used as directed)

The range of noise reduction ratings for existing hearing protectors is approximately 0 to 30 (Higher numbers denote greater effectiveness)

Attenuation Chart         (ANSI S3.19-1974)
Frequency 125 250 500 1000 2000 3150 4000 6300 8000
Mean Attenuation (dB) 36.1 37.4 39.7 38.6 38.5 44.6 45.4 47.4 48
Standard Deviation (dB) 3.6 4.9 4.3 3.1 2.7 3.2 4.1 3.2 3.2

Example:

  1. The environmental noise level as measured at the ear is 92 decibels dB(A).
  2. The NRR is 32 decibels (dB).
  3. The level of the noise entering the ear is approximately 60 dB(A).

ご使用の目安

Ear plugs must be inserted properly for optimum performance.

  1. With clean hands, firmly roll entire ear plug between thumb and fingers to form a thin tight cylinder.
  2. Using one hand, gently lift top of ear up to open ear canal. With other hand, insert rounded end of ear plug.
  3. With forefinger, hold ear plug in place until it expands to form a comfortable, snug fit.

Practice of insertion is recommended. Please refer to the audio and video instructions at HEAROS.com. discard product after several uses or as soon as dirt or wax accumulates on ear plugs.

警告

 Keep away from infants. This product is non-toxic but may interfere with breathing if caught in windpipe.

 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 above instructions for proper fit. Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the Noise Reduction Rating (NRR) 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. The Noise Reduction Rating (NRR) calculated from the attenuation data is 32dB. Ear plugs must be properly fitted to attenuate noise effectively. Refer to instructions.
