Real-Ear Evaluation of Earplugs Using One-Third Octave Bands of Noise.
Abstract
The objective of the test was to evaluate the attenuation characteristics of three earplugs using noise bands as the test signal, and to compare the attenuation characteristics of the Sound Sentry protective device using noise bands to those using pure tones. A real-ear attenuation method using noise bands was utilized to evaluate the attenuation characteristics of the earplugs. Comparison of these data with other data obtained in this laboratory and from a manufacturer's brochure was accomplished for the Sound Sentry device, and two separate studies from this laboratory were used to compare attenuation data for the V.51R earplug for pure tones and noise signals.
