What is a good SNR rating?

Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications.

What does SNR 30 dB mean?

Like the NRR, the SNR gives you an estimate of the level of noise reduction that a hearing protection device can provide. This means that if you come across a product with an SNR of 30, then it's essentially saying that the product can reduce up to 30dB of noise exposure.

What is the highest SNR rating?

About SNR Ratings

So, this means if the environment you're in has a noise level of 80 decibels, the noise reduction of the ear plugs puts the noise level at roughly 55 dB. The highest SNR ratings available at the moment are in the high 30s.

What is difference between SNR and NRR?

Summary. Put simply, SNR and NRR are two standards for measuring the attenuation of a hearing protection product. SNR is the EU standard, while NRR is the US standard. ... It's important to consider the noise environment that the protection will be used in, and how well the hearing protection product is fitted.
