Noise Reduction Ratings (NRR) are required by law to be included on the packaging of all hearing protection devices. Unfortunately, the methods for obtaining these ratings are both outdated and often erroneously applied or misleading. This can lead to the wearer receiving far less protection than he was led to believe. Goforth Audiometrics can verify the amount of protection our wearers are actually receiving through FIT Testing, available onsite when receiving plugs or by appointment.
