| Resumen |
The protection (reduction in A-weighted sound pressure level at the ear) afforded by a hearing protector varies between wearers and between noises. According to the amount of information available on the noise, various methods exist for the estimation of the effective protection afforded by a protector. The octave-band and the single-number method are reviewed, together with their underlying assumptions. Attenuation data on individual wearers for 7 protectors were used in conjunction with 100 noise spectra to test the validity of these assumptions and to calculate and compare the errors of each method. The best single-number method, representing a practical compromise between accuracy and convenience, is one which generates a rating number to be subtracted from the C-weighted sound pressure level of the noise. |
