Hearing Loss

What is ANSI's S3.19-1974 Standards?

Manufacturers of hearing protection are required to evaluate their devices and label them with a Noise Reduction Rating based on ANSI S3.19-1974 . ANSI's S3.19 is the American National Standards Institutes method for measurement of real-ear protection. The ANSI's standards are used to ensure that hearing protection devices provide a predictable level of protection for your ears.

New Junior baby earmuffs have been tested by the ANSI and meet the following standards:

NRR 22dB
Mean Attentuation @ 500Hz    26db
Mean Attentuation @ 1000Hz  30db

What is a dB or Decibel Rating?

A decibel (dB) is a unit of measurement that gages the intensity of a sound. The units define how loud a noise source is, ranging on a comparative scale from 0-194. A dB reading of “0” indicates the faintest sound the human ear can detect, while a dB reading of “180” would be the equivalent to standing on a rocket pad during launch.

Understanding Hearing Protection

The rating levels you see advertised don’t measure how many dB will be reduced from a particular noisy environment, this is a common misunderstanding. In order to calculate the actual protection level given is very important when choosing the right hearing protection for your baby.

To determine how much of a reduction in dB there will be you must take the NRR number, then subtract 7, and then divide by 2. You should then take the dB level in the noisy environment and subtract that number.

For example, if a boat has a steady noise level of 100dB and the hearing protection is rated at NRR 22dB, the formula would look like this: (22-7)/2=7.5. 100-13 = 92.5db.

Based on that, the noise levels that would reach your baby would be 92.5dB. This formula can be used for both ear plugs or ear muffs.

What is noise-induced hearing loss in newborns and infants?

Every day, your infant is exposed to different sounds in their environment, such as the sounds from TV or a stereo, household appliances, and traffic. Generally, these sounds are at safe levels that won’t damage their hearing. However, some sounds can be harmful when they are too loud, even for a short time, or when they are both loud and long-lasting. These sounds can damage sensitive structures in their inner ear and cause noise-induced hearing loss (NIHL).

NIHL can be temporary or permanent, and it can affect one of their ears or both of their ears. Regardless of how it might affect you, one thing is certain: noise-induced hearing loss is something you can prevent by using our New Junior baby earmuffs.


Sound is measured in units referred to as decibels. In most cases sounds of less than 75 decibels, even after long exposure, are not going to cause NIHL. Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. Generally, the louder the sound, the shorter the amount of time it takes for NIHL to take effect.

A normal conversation is usually about 60 decibels and fireworks or a firearm is about 150 decibels. The obvious first rule to protect your infant is to avoid loud noise whenever possible. A good rule of thumb to remember is if you must shout to be heard, then it could be too loud without a pair of New Junior baby earmuffs hearing protection.
