SWIMMING EAR PLUGS SOUND BLOCK EAR PLUGS SILICON EAR PLUGS WATER EAR PLUGS SWIMMING POOL Kalpdev earplugs can give you up to 85% to 95% noise reduction, depending on noise level of environment, user error and few other factors. Earplugs cannot give you Sound Lab like 100% silence. For better understanding of noise reduction capacity of this earplug please read and understand about NRR or Noise reduction rating 4 pair The Noise Reduction Rating (NRR) is a measurement of how effectively hearing protection device (earplugs) reduce the level of noise that reaches the ears.

To use the NRR, you should first determine the noise level of your environment using a sound level meter. Then, subtract the NRR of hearing protection device from the measured noise level to determine the estimated noise level that will reach your ears. For example, if the noise level in your workplace is 95 dB and you are using earplugs with an NRR of 32 dB, the estimated noise level that will reach your ears is 63 dB.

It is important to note that the NRR is not a perfect indicator of actual noise reduction achieved by a hearing protection device. It is a laboratory-based measurement that assumes the user is wearing the device correctly and that the noise environment is similar to the one used in the test. Factors such as poor fit, user error, and variations in noise frequency can all affect the actual noise r
