Abstract |
Sound level conversion (SLC), which results in a single-number value describing the noise reduction (the difference between the source C-level and the received A-level) afforded by ear protectors, was performed for 30 ear protectors in 615 industrial noise spectra. The SLC value is useful for situations in which the noise hazard is characterised only by C- and A-weighted sound levels. A simple procedure for calculating the SLC value, accurate to within ±1dB, is proposed. Protection rates of 50-97@1p can be achieved. |
